In today’s episode we move on to our next sustainable design theme – healthy buildings.

We’ll investigate the design of a house on an off grid site located in Mullumbimby in the Subtropical northern New South Wales hinterland. I talk with architect, Michael Leung, the director of Balanced Earth Architects, who will share the inside story on his Sky Farm project.

Today we’ll learn about:

• The key design considerations, materials and products for a healthy home,
• We talk further about the process, costs and benefits of using hempcrete in custom architectural construction, and
• We’ll also cover a wealth of other insights and practical information drawn from Michael’s extensive experience as both an architect and a builder.

KEY POINTS SUMMARY

1. Healthy building is about interrogating the detail of materials. Often that's not presented on websites and you have to dig deeper into the Material Safety Data sheets.

After extensive research, Balanced Earth Architects now work with a simple palate of materials and the basics include: hempcrete, recycled timber and other materials from demolition, galvanised steel, timber windows, and natural finishes including clay and lime renders.

2. A hempcrete and lime rendered wall composition prevents mould growth. Hempcrete is vapour permeable, allowing moisture to travel from the inside to outside. In addition, lime render has an alkali surface preventing mould growth.

3. A hempcrete wall is set up as follows:

• It can be constructed on a timber framed or concrete floor.
• In timber framed construction, the joists or bearers may be doubled up to carry more load when the hemp is wet. Then a 10 or 20mm compressed FC board is fixed on top as a base for the hempcrete.
• To build the wall, a timber stud frame is setout 80mm in from the external wall line. The 90x45 stud sits centrally in the 250mm hempcrete wall, allowing 80mm of cover on both inside and outside.
• The entire house is constructed with standard timber stud frame construction. All timber can be untreated pine because the lime in the hempcrete protects the timber, and
• The services are clipped into the stud wall, and...]]>Prioritising health when selecting materials and products is simply common sense, and the best thing about healthy materials – they are also brilliant for the environment.

  • The entire house is constructed with standard timber stud frame construction. All timber can be untreated pine because the lime in the hempcrete protects the timber, and
  • The services are clipped into the stud wall, and the formwork is set up ready for the hempcrete.
  
  

  4. Concrete interior floor slabs are burnished and then finished with a natural flax seed oil.

  Burnishing is a process that creates a smooth, dense and low sheen surface by mechanically trowelling a concrete slab before its fully cured. Unlike polished concrete, burnishing does not grind down the concrete or expose aggregate. The process uses a power trowel or helicopter to compact and smooth the surface to a sleek durable finish.

  5. Other healthy internal materials and finishes include:

  • Wall linings of pine boards, plasterboard or Villaboard finished with natural clay or lime paints, and natural clay or lime renders.  
  • Cabinetry carcasses are constructed from VOC free moisture resistant plywood, painted with natural paint. There is no melamine cabinetry.
  • Kitchen benches are made from timber, concrete or a copper treated with natural oils.
  • Wet areas avoid tiles on walls or floors to minimise the opportunity for mould growth in tile joints. Instead the walls are finished in a burnished render. Burnishing involves trowelling the fresh render surface until it is completely smooth and all pores and scratches are removed. Bathroom floors and showers are finished with micro cement and sealed.
  
  

  6. Materials for roof water collection and storage systems avoid chemical leaching and include:

  • Galvanized steel roof sheeting, gutters and downpipes.
  • HDPE pipes (never PVC).
  • Rainwater tanks made from stainless steel or concrete.
  
  

  7. EMR or electromagnetic radiation exposure is reduced - particularly in bedrooms. All cabling in the house is not within 2 metres of any sleeping head, particularly children. Solar panels and batteries are located on sheds or garages and away from sleeping and habitable spaces, and Internet cabling and plug in connection is provided to avoid WIFI wherever possible.

  KEY POINTS SUMMARY

  1. Structural insulated panels or SIPs are used in floors, walls and roofs for residential and light commercial buildings. The panels are made by sandwiching a core of rigid foam plastic insulation between two structural facings and in this case Murray used oriented strandboard (OSB). SIPS are manufactured off site and are custom designed for each project.

  2. SIPs panels do have some timber framing in them, but much less than a standard timber stud wall. The reduced timber content plus the polyurethane insulation deliver better thermal performance than standard insulated timber frame construction.

  3. The external wall composition of this project was as follows:

  • The basic external shell was a 165 mm thick SIPS panel.
  • Externally, the ProClima weathertight membrane was fixed directly to the SIPS board and a 45x45 timber structural cavity batten attached to the outside of the membrane for the external cladding, and
  • Internally, 45 x 45 timber battens were fixed to the SIPs, creating space for services, additional insulation and attachment for internal plasterboard lining.
  
  

  4. Internally, the oriented strandboard lining can be exposed rather than covered with plasterboard to save costs, but this approach makes access to services much more challenging. Additionally, since the strandboard wall serves as the finished surface, it requires protection during construction.

  5. SIPS are very airtight, making them very appealing for use in Passive House projects. Only the joints in the very large SIPS panels require taping.

  And finally,

  6. Important design considerations when using SIPs include:

  • Lintels above doors and windows cannot be concealed within the ceiling, meaning that floor to ceiling glazing is not possible, and
  • SIPS roof panels stop at the wall line resulting in no eaves overhang. Therefore, a custom solution to attach eaves is...]]>SIPS, or structural insulated panels are a fast and efficient way to achieve very high thermal performance.

    KEY POINTS SUMMARY

    1. Cross Laminated Timber (CLT) is an engineered wood panel product created by gluing layers of timber together with the grain alternating at 90 degrees for added strength. CLT panels are cut into entire wall, floor and roof sections with precise computer accuracy.

    2. CLT buildings must be meticulously designed and this includes all openings and holes cut for doors and windows, services, fittings and even power points. Everything must be accurately located in the computer shop drawings because making changes on site is very challenging.

    3. The CLT serves as both the internal wall lining and the structural shell. Externally, it needs thermal insulation, a weather and air tightness building wrap and cladding for weatherproofing. Internally, makers utilise prefabricated stud frame walls in conjunction with CLT to accommodate access to services, particularly in bathrooms.

    4. Once prefabricated, the CLT panels are transported to the site and assembled to create the entire building form. The construction timeline is streamlined because site foundations, retaining walls and service connections can occur simultaneously with the off site CLT prefabrication.

    5. Prefabrication using CLT offers several advantages:

    • It replaces studs, bracing and other structural components.
    • It eliminates the need for trims such as skirtings, cornices and architraves.
    • It's made from locally sourced New Zealand pine.
    • It reduces construction time on site.

      • It enables building on remote or difficult to access sites, sometimes even by helicopter lift, and
      • Off site construction minimises waste and enhances building quality.
      
      

      6. Makers Fabrication are professional builders who also offer CLT cutting and prefabrication services to other architects and industry.

      KEY POINTS SUMMARY

      1. Rammed earth was chosen for this project because it suits the local continental climate. It optimises energy efficiency by absorbing and releasing heat slowly throughout the day, stabilising internal temperatures. This means it helps maintain a moderate temperature range inside the house by absorbing heat in summer to take the edge off those high temperatures and releasing heat slowly in winter to take the edge off low temperatures.

      2. The soil used for rammed earth must be laboratory tested to ensure it is structurally suitable. In Steffen's experience in regional Victoria, there are usually quarries with appropriate soil located within a reasonable distance from most sites. A rammed earth contractor can assist with this process.

      3. The rammed earth construction process is relatively simple and dates back over 10,000 years. Plywood formwork boxes are constructed and a rammed earth mix, of dirt, cement, water and potentially other admixtures is poured in and compacted with specialised equipment. At the time the Butterfly House was constructed, rammed earth walls comprised a single solid wall with a thickness of around 500mm. Now, rammed earth walls must include insulation. Their current composition involves an internal layer of rammed earth, a core of thermal insulation and an outer layer of rammed earth, resulting in an overall wall thickness of around 450mm. Alternatively, rammed earth can be constructed as a 200mm thick reverse brick veneer wall.

      4. Rammed Earth offers numerous benefits, including thermal mass to stabilise internal temperatures, excellent acoustic qualities, high flame resistance, low embodied carbon and durability and a long lifespan,...]]>Are you looking for a unique sustainable material with a low carbon footprint?

      In today's episode, we move on to our next sustainable design theme, Earth Building, and investigate rammed earth construction. Architect Steffen Welsch, director of Steffen Welsch Architects, shares the story behind his Butterfly House project, located on an off-grid site in Rutherglen in the hot, dry summer and cool winter climate of north-eastern Victoria.

      Today we'll learn about the process, benefits and costs of using rammed earth construction and a wealth of insights and practical information drawn from Steffen's extensive experience.

      5. The cost of rammed earth construction is about three to four times higher than that of standard 90mm timber stud frame construction. It's comparable to insulated cavity brick.

      And finally,

      6. Considerations when using rammed earth include:

      • understanding all the benefits and qualities of the material,
      • being aware of regulatory issues. It's not covered in the Australian National Construction Code and requires a performance solution report,
      • engaging the right expertise early, including a sustainability consultant, rammed earth contractor and structural engineer, and
      • co-ordinating all services early in the process.

      KEY POINTS SUMMARY

      1. In this project, like so many others this season, the clients drove the environmental agenda and they were very well educated about environmental design and materials. This is what they were seeking and it's a fantastic brief for everyone to keep in mind:

      • A floor plan sized to suit their needs that connected to a diverse and productive garden.
      • Maximum thermal comfort for now and the future,
      • A life cycle assessment to help understand and reduce their environmental impact and carbon footprint, and
      • All within a modest budget.
      
      

      2. To control costs, the strategy involved standard construction techniques combined with climate responsive design and environmental materials. This included:

      • a single level design,
      • a slab on ground floor,
      • a trussed roof with flat ceilings throughout,
      • a 90mm timber stud frame,
      • external cladding in low maintenance, pre finished compressed fibre cement sheeting, and
      • internal linings in Durra Panel.
      
      

      3. Key strategies for achieving a maximum NatHERs energy efficiency rating in a warm temperate climate included:

      • orienting the house toward the north,
      • appropriately located and sized windows and shading to provide shade in summer, spring and autumn while allowing sunlight in during winter, and
      • ensuring effective ventilation.
      
      

      Also, double glazed, thermally broken, clear glass windows greatly enhanced the thermal performance.

      Also, double glazed, thermally broken, clear glass windows greatly enhanced the thermal performance.

      4. Matt utilised a mix of thermal mass construction techniques throughout the house to stabilise the internal temperature. This included reverse brick veneer walls on selected orientations, exposed concrete slab floor and an internal double brick mass in the kitchen. It's important to note that all the bricks used were recycled.

      5. Durra Panel is an internal wall and ceiling board product made from compressed wheat and rice straw waste with linings on both sides. The default lining is paper, but a range of lining board options are available depending on the application. Durra Panel offers a heap of benefits. It's cost effective, it's renewable, it reuses an agricultural waste product, it sequesters carbon, it's 100% biodegradable, it provides excellent thermal and acoustic insulation and it's very flame resistant.

      And finally,

      6. Durra Panels are around 50mm thick and are screw fixed to a standard stud frame. The key item to note is that you can't have a flush finish like plasterboard. All panel joins must be covered with a timber batten or other cover strip.

      KEY POINTS SUMMARY

      1. The biggest environmental change can be effected through improving existing buildings. Currently in Australia, there is no requirement to upgrade your existing home as part of your renovation. However, Emily always encourages her clients to set aside some budget for this important work to ensure long term comfort and energy efficiency.

      2. Hemp is used in construction in a range of formats. Hempcrete, as covered in this episode, also hemp blocks, hemp sprayed onto a frame and hemp panels.

      3. Hempcrete walls are non-structural. They're formed up around a timber stud frame.

      4. Hempcrete walls can be finished in a number of ways. They can be left unfinished, coated with natural breathing lime render, or a clear, penetrating, breathable sealer coat. Externally, it usually requires extended roof overhangs to prevent weathering.

      5. In Emily's experience, the cost of Hempcrete construction in Sydney by a subcontractor was approximately on par with cavity brickwork. Historically, hemp buildings have been constructed by a community of unskilled friends and family, enabling much lower labour costs.

      6. Hemp offers a multitude of benefits:

      • It delivers very healthy indoor air quality.
      • It's very durable and has a long lifespan.
      • It offers excellent acoustic and thermal insulative performance.
      • It's very fire resistant,
      • It can be made airtight, and
      • It sequesters carbon and is biodegradable at end of life.

      In today’s episode we move onto our next sustainable design theme - renewable materials.

      We’ll investigate the design of a new certified Passive House built from Huff’n’Puff SITUP strawbale wall panels. This house is located on an off grid site in the cool temperate Victorian high country. 

      Architect Talina Edwards, a director at Envirotecture, shares the inside story on her Huff’n’Puff Haus.

      Today we’ll learn about:

      • Biophilic design and our intrinsic connection with nature, Country and our planet
      • The costs and benefits of using straw bale panels and their role in construction
      • Strategies to achieve Net Zero carbon, and
      • A wealth of insights and practical information drawn from Talina’s extensive experience

      KEY POINTS SUMMARY

      1. Biophilic design is linked to care for Country and an understanding that we are part of nature and intrinsically linked with our planet. If we don't care for Mother Earth, she can't keep caring for us. It's a reciprocal relationship of being present, responsible and caring. Like we take responsibility to care for our family.

      We feel better when we're outside in nature, but most of us spend around 80% of our time indoors. Biophilic design is about creating indoor environments that help us feel closer to nature and the outdoors through ideas such as plants, natural light, textures and materials. But it's critical to be very mindful of how our design choices affect the environment. Because remember, it's not only about what is good for us, it's a reciprocal relationship.

      2. The primary driver for using straw bale panels is to create maximum wall insulation in colder or more extreme climate zones. Other benefits include being a renewable material, low embodied carbon and reuse of a waste product from the agricultural industry.

      3. Huff n Puff straw bale wall panels are made from straw bales tightly fitted inside plywood box frames. The panels are typically 350 - 450mm thick, approximately 600 - 1200mm wide and 2.5 – 3m high depending on the project requirements and they're engineered to be load bearing.

      4. Lime mortar or clay mortar can be used on the exterior or interior to seal the straw bales. Limemortar is a natural breathable material that is airtight but vapour permeable, meaning the building can sweat through it. If rendered externally, large eaves are critical to protect the external render from weathering.

      5. Materials like straw bale and hempcrete are not in the building code, so additional consultant reports and engineering input is required. On this project, there were three structural engineers in total: the project structural engineer, the engineer from Huff n Puff for their SITUP panel system, and a third engineer to independently review and verify for the building surveyor.

      And finally,

      6. The use of straw bale panels worked out time and cost comparable to custom builds based on the use of 140mm timber stud framing that Talina typically uses for colder climates. Note: 140mm framing allows for the additional thickness of insulation and is more expensive than 90mm stud framing and insulation used in the majority of Australia.

      KEY POINTS SUMMARY

      1. It's important for architects to educate their clients about the world of opportunity that design and particularly sustainable design offers. And if you're a client of an architect, it will require trust, sometimes bravery and working collaboratively to achieve a unique and environmental home.

      2. If an existing house has character and good bones, think very carefully before demolishing it. Older homes contribute to the character we value in our streets and enhance property value, pride and delight in our suburbs. This character is rarely matched in new low budget homes.

      3. It's easier to salvage and recycle items from demolition if you are living on site. Builders work within tight time frames and usually don't have the resources or time to stockpile materials and determine how to pass them on to a new owner.

      4. An ordinary mid-century home may be cost effectively renovated into something very special through enhancing its existing motifs and design elements. Look for inspiration in the surrounding older homes.

      Paul shared some very wise advice about architectural practice.

      Paul shared some very wise advice about architectural practice.

      5. Architects must be transparent about their commitment to projects and build trust with clients by itemising non-chargeable time and tasks. Clearly itemise work done for free in invoices to ensure that your clients are aware of it. Encourage your builders to also follow this process because it helps to validate trust and the importance of give-and-take on a project.

      6. Validate your construction team on site to build trust. Appreciate the skills they bring and ask their opinion. Creating a happy project site will help the project run smoothly and improve the outcome because happy people communicate better and are more invested.

      KEY POINTS SUMMARY

      1. Old buildings and materials have a unique character that is very difficult to obtain from anything affordable and new. They make a home so much more interesting, inspirational and joyful to live in, adding to quality of life, market appeal, and ultimately property value.

      2. In recent years, interest and awareness of sustainable design have grown in the market, but unfortunately, knowledge has not. Social media, architectural journals and architect websites promote environmental design with glossy, finished project photos, but with limited information about what's going on in the background. These glamorous images support the assumption that environmental buildings are expensive and all about appearance.

      In reality, a house that performs well from a sustainability point of view is not necessarily expensive or glamorous. Unfortunately, many genuinely sustainable houses do not photograph well, so they do not get the interest that they should.

      The next points are about ideas for reusing materials out of your existing building. Rob had heaps of ideas, but these particular ones come up most frequently on a lot of old houses.

      3. Old window glass and old windows can be retained and made safer by applying security film. Old window glass is thinner and more fragile than modern glass and breaks into sharp, jagged shards when shattered, posing a serious safety risk. The application of security film enhances the window's resistance to breakage and holds the shattered glass together.

Old window glass is thinner and more fragile than modern glass and breaks into sharp, jagged shards when shattered, posing a serious safety risk. The application of security film enhances the window's resistance to breakage and holds the shattered glass together.

      4. Old timber T&G floorboards on their last legs can be retained with a thorough cleaning. This approach is beneficial in cases where sanding would expose the tongues, causing the floor to break apart. Rob had to hunt around to find a floor finisher with the right equipment. It requires a machine with something equivalent to a brush rather than a sander.

      For those who don't know, sanding a top nailed floor, which is how all old timber floors are fixed, requires nails to be punched down by hand, which is slow and costly. As an alternative to replacing the floor, your builder might also suggest laying another flooring material on the top. So if you find yourself in this situation, investigate the thorough floor cleaning option first.

      And finally, the lessons learned from this project.

      5. if you're an owner who is building or renovating, you will ultimately control the sustainability of your project. Your architect and builder can propose ideas, but you make the final choices. Rob's clients were great environmental collaborators and constantly pushed to go further.

      6. The primary problem with using materials from demolition is the commonly held belief that buildings must look perfect and new. For recycled materials to be properly embraced by the industry. The owner, architect and builder must question and agree on the final appearance before the work is done. Reducing the amount of reworking saves money, making construction more affordable and ultimately resulting in the use of recycled materials becoming more commonplace.

      They must meet the current occupants’ needs efficiently and enable rearrangement or repurposing to accommodate future needs with minimal work and material waste.

      In today's episode we continue our exploration of the sustainable design fundamentals. We investigate the design of a new house on a standard 600m2 suburban site in Yuggera Country, Samford in subtropical Brisbane. This house contains three different parts; a four bedroom home, a self-contained office and a self-contained secondary dwelling.

      KEY POINTS SUMMARY

      1. The design brief for the average Australian home is not what it used to be, and it keeps changing.

      More people are working from home, children are staying at home longer or they leave only to return with their partners and young children.

      There is a serious shortage of smaller affordable housing suitable for couples, young families or single parent families. For anyone looking for a source of income, incorporating secondary accommodation into your house plans can often provide much needed housing options for others and offer additional flexibility for the future.

      2. Reducing your building footprint to maximise green space is critical and provides multiple benefits, such as improved access to passive ventilation, areas for productive food gardening and support for nature and natural processes.

      3. Ideas to maximise cooling through passive ventilation included providing openings to at least two, if not three sides of every room. Chris used internal courtyards to achieve this. And security solutions that allow the house to remain open and ventilated while locked up.

      4. Ideas to control access to sun in winter and shade in summer included retractable awnings over courtyards, using windows with solid infill instead of glass to provide shade and privacy while allowing ventilation, and adding retractable outdoor curtains to...]]>To be sustainable, buildings must be adaptable and flexible.

      4. Ideas to control access to sun in winter and shade in summer included retractable awnings over courtyards, using windows with solid infill instead of glass to provide shade and privacy while allowing ventilation, and adding retractable outdoor curtains to block hot low angle afternoon sun.

      5. Create a floor plan that will enable air conditioning of selected rooms with optimal energy efficiency. Only air condition reasonably sized rooms. Avoid air conditioning really large open plan areas with voids. Ensure the rooms designated for air conditioning are well insulated and can be effectively sealed to prevent constant energy draw, and install ceiling fans in all rooms.

      And finally,

      6. Chris sourced all his hardwood, including structural members from demolition yards. Chris had the engineering drawings so he knew the sizes that he needed and his engineer performed stress testing of the timber on site to ensure compliance. While using demolition yard timber offers significant environmental benefits, it requires considerable effort. The timber must be sourced, often requiring searching across multiple demolition yards, transported to site and stored on site, often well before construction begins. Once on site, the timber needs sanding to remove splinters.

      KEY POINTS SUMMARY

      1. Houses in hot tropical climates can be comfortable most of the year with access to good natural ventilation and shading. However, they will need a small air-conditioned retreat space designed for optimal energy efficiency for those very hot days every summer.

      2. Belinda's design ideas to maximize ventilation and airflow include:

      Thermal venting by allowing a large volume of cool air to enter at the lower level and as it heats, rise and exit through the upper level.

      • Providing narrow floor plans with windows on opposite sides of the house to promote breeze flow straight through because breezes move best in straight lines through the house,
      • Providing awnings and eaves over windows and doors so they can remain open during rain.
      • Maximising door opening size in this case with sliding stacker doors,
      • Using louvres and casement windows to provide 100% opening. These windows can be angled to channel breeze through the house and also remain open during rain. However, it is important to note if you're designing a room to be opened for maximum ventilation, and also closed for air conditioning with optimal energy efficiency, choose more airtight window openings and this includes casement windows, bifold doors, swing doors. Avoid louvers, sliders and double hung windows because they do not seal shut as effectively.

      3. A common design requirement in cyclonic regions is the psychological need to feel safe. Timber and steel framing is very strong in cyclonic wind speeds when built to the correct engineering standards. However, masonry, and that means concrete block and brick walls make people feel safer from wind borne flying debris. Therefore, Belinda always incorporates a small cyclonic retreat space built with heavy masonry walls.

      4. Ideas to create a small but efficient building floor plan and leave more site area for garden and outdoor space include:

      • Thinking carefully about your design brief and the least you need to be comfortable and happy in your home.
      • Look for opportunities to have multi-purpose rooms.
      • Minimise hallways,
      • Maximise openings around the living area to enable connection to the surrounding garden and a feeling of generosity.
      • Consider a double height volume through the main living area to create a feeling of openness and generosity to offset modest ceiling heights through the rest of the house, and
      • use two levels rather than one big sprawling level on ground.
      
      

      5. Hot tropical climates cause materials to break down quickly if they're not durable. The humidity, high rainfall and living close to large trees is an ideal environment for mould and algae growth and deterioration of materials. Belinda chooses durable, affordable materials such as fibre cement (FC) and concrete block.

      And finally,

      6. Do not compromise on joy and delight in your house design. It does not have to cost more. Home design is so much more than arranging the number and size of rooms. It should focus on optimising quality of life through good natural lighting, connection to nature and the sky, and flexible spaces enabling occupants needs to change over time

      KEY POINTS SUMMARY

      1. Reducing carbon emissions through design is critical, but we must think holistically and find regenerative design solutions that do not focus on carbon at the expense of everything else. Regenerative design aims to integrate the building into a broader system, emphasising ways to give back and create a positive impact rather than merely reducing negative impacts.

      As an example, Andrew could have achieved 10 star NatHERS but chose not to because achieving it would have required upgrading from single to double glazing. This change would have significantly increased his embodied carbon due to the added glass. NatHERS modelling proved that his house design would be comfortable in a subtropical climate without mechanical heating and cooling, and so double glazed windows were not essential.

      2. Relying on rooftop solar power to offset large household energy consumption is not a balanced regenerative approach. It's crucial to prioritise reduction over production. Always explore ways to reduce energy demand first.

      3. Getting the fundamentals of climate responsive design right is a vital starting point for all designs and will significantly enhance energy efficiency.

      3. Getting the fundamentals of climate responsive design right is a vital starting point for all designs and will significantly enhance energy efficiency.

      4. Choosing light coloured exterior paint in hot climates can minimise heat gain and prolong the life of exterior materials. Timber is particularly vulnerable to damage when painted dark colours because the paint essentially seals it in plastic. Dark painted walls and windows absorb large amounts of heat when exposed to the sun, causing the timber inside to steam and break down over a reasonably short time frame. Be aware that most timber window manufacturers in Brisbane and presumably in other hot climates have disclaimers about dark paints on their products which can void warranties.

      5. Always investigate the origin of your timber. If you're choosing new timber, ideally find timber grown locally in Australia or New Zealand. Only choose timber with valid third party forestry certification, FSC or PEFC, to uphold environmental protection and human rights.

      In recent years, many states in Australia have significantly reduced hardwood logging from native forests, making local hardwood more difficult and expensive to obtain. Be aware that affordable hardwood species commonly used for clear finished doors and windows in Australia, like New Guinea rosewood, lack third party chain of custody certification.

      And finally,

      6. Andrew discovered that plasterboard is a very environmental product from a circularity perspective. Initially he believed plywood would be a better option for internal linings, but he found that it contained a highly carbon intensive glue. Additionally, there is no pathway for plywood products to have a second life. Their only circular outcome is energy recovery, meaning incineration. In contrast, plasterboard has a significantly lower whole of life impact than plywood. The gypsum used in plasterboard is easily recycled to create new plasterboard from old materials.

      It's important to note that the material choices made on this project are not universally applicable to all projects. Each project has unique requirements and solutions should be explored on a case by case basis.

But where should we concentrate our efforts to achieve the greatest impact?

      In today's episode, Dr. Paul Matthew, a lecturer and researcher at the University of Queensland School of Architecture, Design and Planning, will share his research on building for a changing climate to help guide us forward.

      Today we'll learn about:

      • The latest climate change science and what we need to focus on in design.
      • The regulatory changes in the pipeline for existing and proposed houses to help tackle climate change,
      • The key steps to achieve net zero carbon, and
      • Loads of other valuable insights, and practical information from Paul's years of research.

      KEY POINTS SUMMARY

      1. The CSIRO have modelled the potential future impacts of climate change over course of the century in all the Australian climate zones. The link to this CSIRO document is in the show notes.

      As the climate warms, design to optimise cooling through cross ventilation in summer will be critical for the whole of Australian. However it’s essential that rooms to be mechanically heated or cooled can be efficiently insulated and sealed to minimise energy consumption.

      2. The Australian Government is planning two significant building regulatory changes to tackle climate change.

      • The first proposed change affects new building work – Embodied carbon calculations are required as part of the Australian National Construction Code approval process. This change was enacted in 2025 in NSW for commercial buildings only. However, the goal at this early stage is to establish a standardized method for measuring embodied carbon.
      • The second proposed change is for existing houses - An operational energy assessment will be required at the point of sale or lease using the NatHERS tool. This change is yet to be enacted, but it's worth noting that a very similar scheme has been in place in the ACT for over 25 years.
      
      

      3. To achieve net zero carbon there are three steps:

      The primary objective is to reduce operational carbon. To create highly energy efficient homes through strategies such as:

      • climate responsive design
      • systems like Passive House
      • adding rooftop PV panels, and
      • purchasing renewable energy via the grid

      • climate responsive design
      • systems like Passive House
      • adding rooftop PV panels, and
      • purchasing renewable energy via the grid
      
      

      The secondary objective is to reduce embodied carbon by:

      • maintaining and reusing existing buildings, rather than demolishing and rebuilding, and
      • choosing lower embodied energy materials.
      
      

      And then finally, once we've reduced operational and embodied carbon as much as possible,

      • looking at carbon offsets to balance out the remaining embodied and operational carbon. But be very careful where your offsets come from because they are not all legitimate.
      
      

      4. To effectively sequester carbon in a timber building, the building must stay in place for up to a thousand years. If all or part of the building is demolished before that time, and the timber breaks down in a landfill, the carbon will be released back into the atmosphere.

      5. A lifecycle assessment is a method of evaluating the environmental impacts of a building from the creation of its components, construction, operation and refurbishment to its ultimate deconstruction and disposal. It looks at a comprehensive range of environmental impacts. Lifecycle assessments are currently predominantly used for large-scale commercial projects but are equally valuable for houses.

      6. Circular economy thinking is based on the concept of the closed-loop system. It involves designing to minimize waste and maximize resource efficiency by keeping materials in use for as long as possible.

      There is a hierarchy of 10 broad R strategies. The objective is to stay up as high as possible. So rethinking and reducing is better than reusing or repairing, and reusing and repairing is better than recycling or recovering.

      NOTE: These are the opinions of Dr Paul Matthew and he is not speaking on behalf of The University of Queensland

       

      INTERVIEW QUESTIONS

      [00:01:11] How did your passion for sustainable architecture begin?

      [00:03:42] Please clarify the meaning of the term sustainable architecture?

      [00:09:11] What are the current global predictions for climate change from the IPCC?

      [00:10:47] What are the climate change scenarios forecast for Australia?

      [00:13:23] How do the CSIRO climate change scenarios align with the Paris Agreement and Australia's commitment to net zero emissions by 2050?

      [00:16:08] Can you tell us what NatHERS is and how it works?

      [00:22:48] There are two building regulatory changes in the pipeline for Australia to tackle climate change - the first one is for existing houses and operational energy assessments at the point of sale or lease. Can you tell us about that?

      [00:25:07] The second regulatory change in the pipeline is about calculating embodied carbon. Can you tell us about that?

      [00:26:20] Can you explain net zero whole of life carbon?

      [00:28:51] What should we focus on in design to work towards net zero whole of life carbon?

      [00:36:43] Where's everything moving to with electric energy supply and use?

      [00:40:00] Does choosing timber construction for carbon sequestration make a difference?

      [00:46:17] What is a life cycle assessment?

      [00:54:47] Are lifecycle assessments applicable for use on houses?

      [00:57:08] What does Circularity mean?

      [01:02:32] Key Points Summary

       

      IN THE NEXT EPISODE

      Next week, we continue exploring the latest science and delve further into the importance of regenerative design and circular economy thinking.

      We’ll investigate the renovation and extension of a 150 year old timber cottage on a small suburban inner-city site in subtropical Brisbane.

      I talk to architect, Andrew Noonan, director of Andrew Noonan Architect who will share the inside story on renovating his own home. Andrew extensively researched his design, product and material choices to ensure they optimised regenerative outcomes and he shares his very interesting findings.

      SEASON KEY POINTS SUMMARY

      The three key messages I want you to take away from this season are:

      1.      Less is more. Less is More encompasses ideas such as:

      • building only the necessary floor area,
      • reducing our building footprint to allow more space for natural processes,
      • reusing our existing buildings and sending less waste to landfill,
      • choosing materials with lower negative impact - local, renewable, high quality and durable,
      
      

      And most importantly, Less Is More is all about making choices that lead to cost savings, both upfront and over the long term.

      2. The importance of creating joy through design. Homes and buildings designed to inspire happiness are more likely to be cherished and maintained over the long term with minimal demolition or alteration.

      As you'll discover in the upcoming episodes, creating joy is often easier and more affordable when reusing older buildings and materials, thanks to their inherent history and connection to place.

      And finally,

      3. The pivotal role that the owner - the person who pays for the building - plays in sustainable design. Every decision ultimately comes down to cost. The building must fit within the owner's budget, so the owner ultimately has the final say.

      If you're an owner who wants to do more for the environment, I am so glad you're here.

      This season will provide you with valuable knowledge and ideas that you can share with your design and construction team.

      KEY POINTS SUMMARY

       

      I'll start with the information about the Australian Passive House Association.

      The association have been advocating for the adoption of the Passive House standard in Australia since 2013. One of the primary barriers to Passive House worldwide is the lack of education. So the association provide everything you need to know in a range of learning formats. Following is a quick snapshot of what they offer and you can find further info on their website.

      They offer free information including:

      • A searchable project database, consultant database and general info blog on their website.
      • Free information sessions in your office to introduce the Passive House basics and benefits.
      • Free one-on-one support for large organisations and government through their Passive House Incubator and this service is designed to help integrate Passive House into building procurement policies, and
      • Free open days to visit Passive House buildings all around Australia.
      
      

      Their paid information options include:

      • Association membership, providing access to online forums where you can ask for support and advice, plus local chapter meetings in each state to discuss local issues.
      • Online courses including the Certified Passive House Designer course and the Certified Passive House Tradesperson course.
      • Plus they offer a hands on construction training course in all states and that's open to anybody, and
      • Their annual conference.

      Renew has been advocating, researching and providing independent practical advice to Australians wanting to live more sustainably for over 40 years. Sanctuary Modern Green Homes is Australia's only dedicated sustainable house design magazine and it profiles the best in environmentally aware architecture and design solutions.

      • If you're looking for information about Passive House products, project consultants and builders, you can search the Renew website and find a heap of previous magazine editions profiling Passive Houses,
      • Also once a year Renew hosts Sustainable House Day which is a free, nationwide open house event where you can visit sustainable houses, some of which will be Passive Houses or take a virtual online tour.
      • All of the virtual tours from the previous years can be accessed on the Renew YouTube channel.
      
      

      
      

      And my final points,

      If you want to experience Passive House for yourself - the temperature, the air quality and the quietness - then why not have a holiday in a Passive House? I've scoured the Internet to find all the Passive House holiday accommodation available in Australia and New Zealand and there are some amazing architecturally designed properties.

      Plus, if you're planning a Passive House or high performance project, you can also find a PDF list of all the suppliers used by my guests this season.

      You can find these two downloadable lists - the accommodation and the supplies list - on the Renovation Collaborative website FREE page.

      KEY POINTS SUMMARY

      1. The 5 Passive House design components for a subtropical climate are as follows:

      • Windows are typically double-glazed and always operable. Windows should enable cross ventilation, purging of any excess heat build-up, and connection to the outdoors to enjoy comfortable external temperatures over spring and autumn and much of winter.
      • The fresh air circulation system for subtropical is an ERV (energy recovery ventilation system) which is different to the HRV systems used in the cooler southern states.
      • Wall insulation can fit within a typical 90mm timber stud framed wall thickness. No under-slab insulation is required because connecting to comfortable earth temperatures (usually around 22-23 degrees Centigrade) is beneficial for cooling.
      • Only one layer of external wrapping is required; the vapour-permeable weatherproof membrane on the outside of the home is taped, sealed and made airtight. An additional internal membrane may be used to obtain certainty of airtightness, but it can be avoided in most cases to reduce costs.
      • Removing thermal bridges is always essential to avoid heat gain.
      
      

      2. Effective shading to avoid all heat gain is critical - no sun can enter the house. Passive houses retain heat very effectively because they are well-insulated and sealed; therefore, the hotter the climate zone, the more shading is required.

      3. Humidity and condensation are major issues in subtropical design. It’s always essential to run a Wufi analysis (which is a moisture study) as well as the PHPP modelling to resolve any moisture issues and prevent unseen mould growth in the building structure over the long term. .

If you’d like to hear more about the Wufi analysis you can find more information in Episode 4. Passive House Consultant and Certifier – with Luc Plowman the director of Detail Green.

      4. A dehumidification system is usually required in subtropical.  The dehumidification system can be added to the ERV system in line or added as a separate system.

      5. Active cooling through air-conditioning is usually required. H4 Living use split system or ducted air-conditioning systems depending on their client preferences. If you choose a ducted system, its critical that the ducts are within the insulated building envelope to maintain optimal energy efficiency.

      And finally,

      6. H4 Living offer passive house consulting advice covering both design and construction. They can work with you on design, help you choose the right builder and also get your chosen builder up to speed on the Passive House construction process.

      In today's episode, I continue to investigate the design specifics for each of the four climate zones around Australia, where most of our population lives.

      I talk to very experienced Passive House designer Ben Caine, the director of the award-winning practice Leanhaus Architecture in Perth. Ben’s architectural mission is to deliver well-thought-out, mindful, architectural homes to the passive house standard, at less cost than a typical architecturally designed home. Ben explains the Passive House design specifics for Warm Temperate, plus he shares ideas on cost savings and heaps of other information and insights from his years of experience to help you better understand Passive House.

      KEY POINT SUMMARY

      1. Through his practice, Leanhaus Architecture, Ben delivers well-thought-out, mindful architectural homes to the passive house standard for a lower cost than a typical architecturally designed home. His practice proves that if you are open to finding efficiencies across design and construction, you can have a passive house or high-performance home without the additional cost.

      
      

      2. Ben generally designs to the Passive House standard without going as far as certification for the simple reason that Passive House certification adds cost. However, it’s essential to note that during the first four years of Leanhaus Architecture, Ben and his team went to great lengths to model, test and optimize every design and understand the exact formula for success. They can now confidently deliver to the passive house standard without the extra cost.

        • Removing thermal bridges is always essential.
        
        

         

        4. Shading is critical, particularly from low-angle sun from the east and west and even from the south in summer. Passive houses retain heat effectively because they are well-insulated and sealed; therefore, the hotter the climate zone, the more shading is required.

         

        5. Reverse cycle air conditioning systems are predominantly used for cooling. The heat load created in the house through cooking, showering, etc. is sufficient for heating. The air-conditioning system size is minimal, at 20 Watts per square metre or less. By contrast, for an ordinary house an air-conditioning contractor would typically provide 60 to 80 Watts per square meter. As an example, Ben has a 6 kW split system for his entire 240m2 house.

         

        6. Australian passive house design is very different from passive house design in the extremely cold climates in Europe. Our sunny, comfortable climate allows us to live with an indoor-outdoor connection. People associate Australian architectural design and modern living with large expanses of glazing, particularly connecting to outdoor living spaces. Passive house design in Australia retains those big expanses of glass and the Australian way of living as much as possible. It maintains people’s expectations of what an Australian house should look like while exceeding expectations about health, comfort and energy efficiency performance.

        In today's episode, I continue to investigate the design specifics for each of the four climate zones around Australia where most of our population lives. I talk to very experienced Passive House designer Andy Marlow, a director of the award winning environmental practice Envirotecture in Victoria and New South Wales.

        In this episode, Andy explains the Passive House design specifics for Mild Temperate. Plus we talk more about Enerfit, the renovation and retrofit tool, and he shares heaps of other information and insights from his years of experience to help you better understand Passive House.

        KEY POINT SUMMARY

        1. In terms of the five Passive House design components, mild temperate is very similar to cool temperate.

        • Windows are double or sometimes triple glazed depending on the design.
        • The fresh air circulation system is an HRV
        • Stud framed wall thicknesses are typically 140mm to allow for more insulation, and insulation is required to separate a concrete floor slab from the cool earth temperature below.
        • An internal wrap for air tightness and moisture control is usually required in addition to the exterior weather tight wrap, and
        • Removing thermal bridges is always important.
        
        

        2. The colour of the roof and walls is considered in the PHPP modelling and affects the design's performance. In cooler climates, dark coloured buildings perform slightly better than light coloured buildings. Dark coloured roof and walls will dry out faster which can be beneficial to reduce any moisture in the wall and roof structure. However, Andy noted that as a nation going forward into climate change and increasing temperatures, generally speaking, lighter coloured buildings are the best solution.

        3. Passive House is a performance standard so buildings can be constructed from any material as long as they deliver the required results through the PHPP modelling. Andy references a Passive House that Envirotecture have completed made from straw bale.

        4. Passive House certification costs around 3 to 8% extra, however the value it adds far outweighs the extra cost. Envirotecture prefer to build certified Passive Houses over uncertified high performance because of the rigorous testing on site. The quality assurance.

        4. Passive House certification costs around 3 to 8% extra, however the value it adds far outweighs the extra cost. Envirotecture prefer to build certified Passive Houses over uncertified high performance because of the rigorous testing on site. The quality assurance.

        5. When renovating, the whole building must be upgraded to achieve Enerfit certification. Improvements must be made to the existing building where possible, but the new work will carry the existing. This is very different to the Australian National Construction Code in many parts of Australia which only requires the new work to be constructed to the current code requirements.

        However, building is expensive and if you can't afford to upgrade the whole house, please don't let this put you off building your new extension to the Passive House standard. The new work needs to have an airtight door that separates it from the existing house and it won't be able to be formally certified. But if it's living areas where you spend most of your time, it will be well worthwhile and add substantial comfort and value.

        And finally,

        6. Enerfit Heritage renovations are definitely the most challenging. Most of the renovation work is done on the interior to retain the exterior character. Andy notes that you don't always need to replace the windows, particularly if they're beautiful character windows such as lead light stained glass. There are other solutions available.

        KEY POINTS SUMMARY

        1. Passive House design for cool temperate climates has a focus on warming. Of the four Australian climate zones accommodating most of our population, cool temperate is the most extreme. In Canberra, winters regularly go down to less than -5 degrees Celsius and in summer can reach the 40s.

        2. Using a compact building form makes the Passive House standard much easier to achieve in more extreme climates like cool temperate. However, if you want a more linear form because of your site or to capture views etc. The PHPP tool can be used to determine building form alternatives and compensate for heat loss in other ways.

        3. Windows are generally triple glazed. The window glass area reduces as the climate becomes colder to reduce heat loss. However, it's still critical to have opening windows in all habitable rooms to get cross ventilation when needed. And shading is still very important to prevent too much heat gain.

        4. The fresh air circulation system is a HRV, which stands for Heat Recovery Ventilation System. The HRV provides a constant supply of filtered fresh air and incorporates a highly efficient heat exchanger to retain heat from inside the house. Some additional mechanical heating, usually from a reverse cycle air conditioner, is generally required.

        As a side note, Michael clearly explains how Passive House heating is generated from three sources:

        i) Solar heat gain,

        ii) Internal gains from occupants, showering, cooking and equipment, etc.

        iii) Mechanical heating.

        The air tightness and insulation in a Passive House very efficiently retains the heat inside the house.

        5. An internal air barrier is required in a cool temperate climate zone and this is in addition to the vapour permeable external membrane used for weatherproofing. Heat energy]]>Passive House design is different in every climate zone.

        iii) Mechanical heating.

        The air tightness and insulation in a Passive House very efficiently retains the heat inside the house.

        5. An internal air barrier is required in a cool temperate climate zone and this is in addition to the vapour permeable external membrane used for weatherproofing. Heat energy moves from warm to cold, so in a cool temperate climate this is generally from inside the house where it's warm, through the building envelope to outside the house where it's cool.

        Moisture is created inside the house by breathing, showering and cooking, etc. An air barrier such as a membrane is installed on the inside face of the wall to prevent moisture laden warm air from moving through the wall structure. This eliminates the risk of condensation and mould growth within the wall.

        A HRV system continuously extracts that stale humid air from spaces such as kitchen and laundry and bathrooms. Building elements and construction details that create thermal bridges are either designed out or analysed and modified if necessary to ensure that surface temperatures never drop so low that condensation can form.

        And my final point,

        6. Insulation is increased. The standard wall solution is a 140mm timber stud frame to allow for the increased width of an R4 wall batt. If you're using concrete floor slab construction, it requires continuous insulation to reduce heat losses to the ground, as well as to the slab edge. Depending on the engineering requirements and the preferred flooring finish, the insulation can be either below or above the slab.

        And finally, additional insulation in the roof is required, creating a completely insulated envelope.

        KEY POINTS SUMMARY

        1. Involving the builder during design is critical for keeping the project on budget. PHPP is used to test and find a balance of the best design and product options that meet the Passive House standard. And so when you include the builder's cost advice during PHPP design stages, you can effectively balance performance and cost to get the optimal outcome.

        2. Passive House projects are easier to build than typical houses because of the high level of communication and collaboration. A specific outcome (Passive House certification) must be delivered and everyone wants to get it right. It's a shared goal. Everyone involved cares about what they do and works together.

        3. The main difference between Passive House construction and typical construction is airtightness. Successful building wrapping is about getting prepared and thinking ahead. Once you understand, it's not that difficult, but there is extra time and cost involved. To wrap a standard house internally, it takes about three or four people an extra week.

        4. Passive House certification gives you the unquestionable guarantee that what is designed is built. There is no other method on the market that will do that. There are multiple tests during construction to confirm that everything is built correctly, including blower door testing to confirm the air tightness, thermal imaging to confirm the insulation is installed correctly, and visual inspections and photographic documentation of evidence to confirm the right products and installation methods have been used.

        IN THE NEXT EPISODE

        Next week we move on to the next step in the process:

        Know your climate zone.

        Passive House design is different in every climate zone. Over the next four episodes, I talk to Passive House designers in the four Australian climate zones where most of our population lives to discover the key design differences.

        First up, I cover Passive House design for cool temperate climates like Canberra, Hobart and Launceston. I talk to Michael Tolhurst, the director of the award winning practice Envelope Architecture in Canberra. He shares the specifics of climate design plus heaps of other insights to help you better understand Passive House design.

They require double glazing and sometimes triple glazing, and they open and close in different ways.

        Glass windows and doors are an integral part of building design, functionality and energy efficiency and they always take a large portion of the budget. So it's critical to know what you're working with before you get started.

        
        

        In today's episode, I talk to Paul Gerrard, the owner of Energy Efficient Windows, about the uPVC windows he manufactures for Passive Houses and high performance homes all around Australia. You'll learn:

        • The different window and door types that can be used in a Passive House,
        • The answers to your questions about UPVC window frames,
        • Plus heaps of other practical info to help you understand how windows work in a Passive House.

        KEY POINTS SUMMARY

        1. Passive House windows are different to the typical windows that we're used to in Australia. The main Passive House options are tilt and turn windows, lift and slide doors and hinged swing doors. These opening types comply with the airtight requirements. They lock the entire perimeter of the window and really compress the seals.

        2. Passive House windows need to be double or triple glazed. The option that's correct for your climate zone will be determined through your PHPP calculations.

        3. The window frame material is also part of the window energy equation, not just the window glass. It needs to be insulated and airtight and thermal bridge free, meaning that the heat energy can't transfer through the window frame from inside to out, or outside to in.

        4. uPVC windows are the most cost effective Passive House window option. Other options include timber thermally broken aluminium and timber aluminium composite.

        5. The window brand and type you choose doesn't need to be a certified component through the German Passive House Institute. As long as the required data on the window glass and the frames is available, the PHPP calculations can be balanced with everything else in the house to achieve the Passive House standard.

        6. A few facts about uPVC windows:

        • uPVC doesn't off gas like a vinyl floor.
        • It has a very long lifespan.
        • It won't break down in the sun because it contains a special tropical mix for the hot Australian climate.
        • It's 100% recyclable in bushfire areas,
        • It can go up to BAL40 in bushfire zones and...]]>Passive House windows are not like the typical windows that we are used to in Australia. They require double glazing and sometimes triple glazing, and they open and close in different ways.

          KEY POINTS SUMMARY

          To conclude today, I want to draw your attention to six main points.

          1. The market for Passive House in Australia has grown exponentially since about 2015. It's really come on in the past few years as the number of built Passive House projects has increased, enabling more people to experience and understand it.

          2. Enerfit is the Passive House tool for renovations. It's more challenging and expensive than new build because you need to replace windows and remove cladding to properly address the requirements, but everything is possible so it's worth investigating feasibility.

          3. A Passive House Consultant is particularly helpful for a first time Passive House team. They do the Passive House scientific modelling on the PHPP program to inform the design through the entire design, construction and certification process.

          4. A Passive House Certifier's role is to provide independent review and quality assurance. They don't get involved in the design process at all. They sit in the background and provide technical support at multiple stages.

          5. Building a custom architectural home to the Passive House standard adds around 10% as a rough rule of thumb. Simple design solutions can cost less.

          6. Building a commercial building to the Passive House standard is not much of an uplift in cost above typical construction in mild climates like Sydney. Luc forecast that Passive House would become standard practice for commercial in Australia over the coming years. From an owner's perspective, it's not much more expensive to build, delivering low running costs and a more robust building. From a user's perspective, it's a healthier, more thermally comfortable building and therefore a more desirable and productive working environment.

          KEY POINTS SUMMARY

          1. There are five design components that the passive house standard uses to achieve its outcomes of energy efficiency and indoor air temperature and quality:

          • Thermal insulation: This is about keeping the warmth in during winter and the hot out during summer.
          • High-performance windows: These are for thermal insulation.
          • Air tightness: This is about sealing your building so there are minimal gaps where the heat energy can get in and out.
          • Heat recovery ventilation system: This brings filtered, fresh outside air into your home and evenly distributes it without losing the thermal efficiency of everything else you're doing.
          • Thermal bridge-free construction: This stops heat energy transfer through materials from outside in, or inside to out.
          
          

          2. You also need mechanical heating or cooling but only a minimal system. A passive house requires much less energy to cool or heat it than a very leaky house where you will constantly be running the air conditioning.

          3. You can open the windows when the external conditions are right and the temperature and the relative humidity outside are pleasant. Opening the windows, feeling the natural breeze, and hearing the birds outside are essential to a healthy home. The heat recovery ventilation system will remain running.

          4. What is the difference between a passive house and a passive solar or climate-responsive design?

          • Traditional passive solar design (in the southern hemisphere) is about orientating the glazing primarily to the north to enable sun or shade into the house to passively warm or keep it cool, depending on the season. In addition, climate-responsive houses are deliberately open to optimise cross ventilation and don't seal very well.

            KEY POINTS SUMMARY

            1. There are five design components that the passive house standard uses to achieve its outcomes of energy efficiency and indoor air temperature and quality:

            • Thermal insulation: This is about keeping the warmth in during winter and the hot out during summer.
            • High-performance windows: These are for thermal insulation.
            • Air tightness: This is about sealing your building so there are minimal gaps where the heat energy can get in and out.
            • Heat recovery ventilation system: This brings filtered, fresh outside air into your home and evenly distributes it without losing the thermal efficiency of everything else you're doing.
            • Thermal bridge-free construction: This stops heat energy transfer through materials from outside in, or inside to out.
            
            

            2. You also need mechanical heating or cooling but only a minimal system. A passive house requires much less energy to cool or heat it than a very leaky house where you will constantly be running the air conditioning.

            3. You can open the windows when the external conditions are right and the temperature and the relative humidity outside are pleasant. Opening the windows, feeling the natural breeze, and hearing the birds outside are essential to a healthy home. The heat recovery ventilation system will remain running.

            4. What is the difference between a passive house and a passive solar or climate-responsive design?

            • Traditional passive solar design (in the southern hemisphere) is about orientating the glazing primarily to the north to enable sun or shade into the house to passively warm or keep it cool, depending on the season. In addition, climate-responsive houses are deliberately open to optimise cross ventilation and don't seal very well.
            • In future climate scenarios, there will be extreme heat peak days, day on day on day. Mechanical heating and cooling will be essential. Climate-responsive houses are not well sealed, so they can't run efficiently.
            • The advantage of the Passive House standard is that you can seal it all up and run a very efficient air conditioning system to maintain thermal comfort. The passive within passive house means it looks after the temperature for you with minimal input.
            
            

            5. You can achieve the health, comfort and energy benefits of a passive House without going as far as formal certification. However, it's essential to understand that the certification process is necessary for QA (and we will talk more about this in the next episode). In a non-certified 'High Performance' home, the insulation, windows and heat recovery ventilation system are the same, but the airtightness requirements are lower than the strict passive house standard.

            6. How does the airtightness of the passive house standard compare with the typical Australian home?

            • 15-20 air changes per hour: The average Australian house. This means that with all the doors and windows shut, all the air in the house could change over or escape to the outside/ come in 15 to 20 times in a single hour.
            • 6.0 air changes per hour or less: A heat recovery ventilation system (fresh air circulation system) is required to avoid mould.
            • 3.0 air changes per hour: Alexander considers this a 'high performance' building.
            • 1.0 air change per hour or less: Enerfit - Passive House renovation/ refurbishment standard.
            • 0.6 air changes per hour or less - The Passive House standard.

            Today, you are going to find out.

            In this first episode, I let passive house speak for itself through the experience of 5 passive house owners from different climate zones around Australia. Most of them are home owners, but my final guest is from a commercial building, because passive house delivers incredible benefits for all building types, not just houses!

            
            

            In today's episode, my 5 guests explain:

            • What made them decide to build a passive house,
            • Their concerns before they started,
            • What they now love most about their passive house, and
            • How it has affected their lifestyle.
            
            

            The interviews bring to light surprising information and sweep away all misconceptions and scepticism.

            
            

            One thing to note:

            You’ll hear in the interviews that some guests live in Passive Houses, and some live in Passive House style high performance homes. The high performance homes incorporate all the components, testing and outcomes of a Passive House, but have not sought formal certification.

            You’ll find out more about the pros and cons of formal certification in Episode 4 with the Passive House consultant and Certifier Luc Plowman from Detail Green

            1. Passive House delivers genuine health and comfort benefits. The temperature is always stable and pleasant. It's quiet and calm inside the house. There's no mould and the filtered air keeps dust, dirt and pollen and all other pollutants out of the house.

            2. It's low maintenance. Because the windows can stay shut, the dirt and dust build up slower and there are no insects and spiders, so there's a lot less cleaning. The bathrooms can stay dry and fresh and your towels are dry within a few hours.

            3. You can still connect with the outside like any typical home. You can open the windows whenever the weather is comfortable outside, or just to hear the birds sing, feel a breeze or talk to the neighbours.

            4. Passive Houses require a specialised system to duct filtered outdoor air throughout the house. This is called a HRV or an ERV depending on your climate zone. It's silent and you can't feel it. The air is just trickling out at the ceiling level. You also need some air conditioning to fine tune the temperature to a small degree or for a minimum amount of time. You're not running an air conditioning unit on full for hours at a time.

            5. There are substantial energy use and running cost savings. The HRV or ERV energy use is negligible at about 80 watts, so if you had to compare that to something, it's...]]>What's it really like in passive house?

            6. The Australian National Construction Code Energy requirements for houses would have to be some of the lowest in the Westernised world. All my guests could not understand why anyone in the industry could turn their back on the science and evidence of Passive House and continue to build in this outdated way.

              KEY POINTS SUMMARY

              To conclude today, I want to draw your attention to three main points.

              1. Interest rates are remaining fairly steady. We are at the end of the interest rate rising cycle. However, another rise is not out of the question because inflation still remains high.

              2. Australians are taking out higher mortgages than ever before. You are not alone. Ten years ago, the average Australian mortgage was around $600,000 to $700,000 across major capital cities. Now we're starting to see seven figure mortgages across major capital cities for new entrants to the property market.

              3. A financial adviser can help you determine the level of home loan debt that's affordable for your personal situation. This can include budgeting, cash flow management, and stress testing to ensure that you can tolerate a level of interest rate rise comfortably.

              
              

              ADDITIONAL ADVICE FROM TIM WARD

              Steps to help you work out the right amount to borrow

              The best process to do this is to reverse engineer what you can afford. These steps will ensure that you can live within your means and do not unknowingly force yourself into undue financial pressure.

              Step 1. Most importantly, don't use the maximum borrowing capacity afforded to you by the bank.

              Step 2. Create a budget with all your non-discretionary and discretionary items. Non-discretionary are things that you have to pay, like rates, utilities, phones, insurances. Discretionary items are things that you choose to pay for entertainment, for quality of life and lifestyle.

              Step 3. See how much is left over for paying off your home loan.

              Step 4. Stress test your affordability of the loan and this means if interest rates increase 2- 3% from current rates, can you still afford them?

              
              

              How much is too much to borrow in 2024-2025?

              In Australia, the typical cost of housing as a percentage of gross income has been around 25% to 30%. How much is too much? The answer is definitely not one size fits all.

              As a general guide, if your home loan repayments are higher than 30% of your gross income, you're more likely to struggle with financial stress. If]]>Are you pondering taking a very large home loan to renovate, build or buy a new house?

              KEY POINTS SUMMARY

              To conclude today, I want to draw your attention to three main points.

              1. Richard forecast that interest rates would remain fairly stable over the next twelve months.

              2. There's a high demand for more houses all over Australia, coupled with a shortage of available houses. Southeast Queensland alone has a shortage of about 14,000 homes a year, and this demand is pushing up house prices with no sign of stopping.

              Brisbane's long-term average medium house price growth rate is around 6 - 8%. And this means two things:

              • House prices are rising steadily. If you're a first-time home buyer in southeast Queensland, get into the market before it becomes even more unaffordable.
              • It also means that property in southeast Queensland is very desirable for investors.
              
              

              3. If you are looking for a bank that supports the environment, there are a few around. Richard mentioned a great website listing banks that don't invest in fossil fuels. Here is the link:

              You might think of mortgage brokers only for getting the best home loan rates, but they've got a lot more knowledge and value to offer than that. Loans for construction and renovation are definitely not one size fits all.

              When it comes to construction projects, everyone has different objectives: large projects, small projects, owner-builders, licensed builders, and even modular or relocated homes. And that's just the beginning. Not all banks will finance everything, because from the bank's perspective, there are different levels of risk. So, finding out what finance is available for your project ideas is essential before you go too far.

              KEY POINTS SUMMARY

              There are so many key points from today that narrowing it down to three is hard, but I'll start with these.

              1.Depending on your personal financial situation and construction project specifics, you can access a number of loan types. You may also be able to access finance for the design stage consultants as well as the construction.

              As a general guide, the standard loan types are construction loans and smaller renovation loans. A construction Loan is for projects over about $150,000. It involves a licensed builder and payments made over the standard stages in a construction contract. The alternative is smaller renovation loans for more cosmetic work under the $100,000 mark. This is for bathrooms, kitchens, and other similar projects where you don't necessarily have to have a licensed builder. You can manage the process yourself, and the amount of money will be paid out in a lump sum drawn down at your discretion.

              2.Some projects will require specialized loans, and limited lenders will be available. Typical examples of this are when you're going to be an owner builder for a large project of a size potentially that would have usually been covered by a typical construction loan. Also, if you're looking for finance for a relocated home, modular home, prefabricated home, or something similar.

              3.If you need finance, getting in touch with a mortgage broker at three key stages is essential.

              • The first stage is the initial discussion. Before you start any design, you need to determine your budget so it can guide your design brief.
              • The next stage is pre-approval finance. When you've got some draft floor plans and more of an idea of what you want to do, be aware that pre-approval finance is only valid for 90 days....]]>Today, we move on to the next step in the Renovate or Sell journey - Borrowing finance.

                You might think of mortgage brokers only for getting the best home loan rates, but they've got a lot more knowledge and value to offer than that. Loans for construction and renovation are definitely not one size fits all.

                When it comes to construction projects, everyone has different objectives: large projects, small projects, owner-builders, licensed builders, and even modular or relocated homes. And that's just the beginning. Not all banks will finance everything, because from the bank's perspective, there are different levels of risk. So, finding out what finance is available for your project ideas is essential before you go too far.

                I talk to highly respected mortgage broker Richard Jefferies from Newbridge Home Loans in Brisbane.

                KEY POINTS SUMMARY

                There are so many key points from today that narrowing it down to three is hard, but I'll start with these.

                1.Depending on your personal financial situation and construction project specifics, you can access a number of loan types. You may also be able to access finance for the design stage consultants as well as the construction.

                As a general guide, the standard loan types are construction loans and smaller renovation loans. A construction Loan is for projects over about $150,000. It involves a licensed builder and payments made over the standard stages in a construction contract. The alternative is smaller renovation loans for more cosmetic work under the $100,000 mark. This is for bathrooms, kitchens, and other similar projects where you don't necessarily have to have a licensed builder. You can manage the process yourself, and the amount of money will be paid out in a lump sum drawn down at your discretion.

                2.Some projects will require specialized loans, and limited lenders will be available. Typical examples of this are when you're going to be an owner builder for a large project of a size potentially that would have usually been covered by a typical construction loan. Also, if you're looking for finance for a relocated home, modular home, prefabricated home, or something similar.

                3.If you need finance, getting in touch with a mortgage broker at three key stages is essential.

                • The first stage is the initial discussion. Before you start any design, you need to determine your budget so it can guide your design brief.
                • The next stage is pre-approval finance. When you've got some draft floor plans and more of an idea of what you want to do, be aware that pre-approval finance is only valid for 90 days.
                • The final step, obviously, is the final approval stage. When you've got all of your information together and your building approval in place,
                
                

                It's important to note that you should consider your mortgage broker as part of your consultant team. You need to keep them up to date as the project progresses and ensure they're aware of any budget changes that may affect the amount of money you need to borrow.

                KEY POINTS SUMMARY

                Another fantastic interview with Tim Douglas. I just want to draw your attention to three main points from today.

                1. Firstly, the property market is showing growth in most Australian capital cities, with Brisbane looking particularly strong going into the Olympics. Brisbane has had a very strong run since COVID and there's no sign of that stopping over the next 7 - 8 years.

                2. Secondly, the high price of construction over the past few years has led to a shortage of completed larger renovations and new houses in the Brisbane market. Therefore, these products are now in high demand. On the flip side, unrenovated smaller cottages are not performing as well as they used to. This is obviously because there's not as much enthusiasm for renovating as there used to be, making these products less desirable. Tim advised that if you're able to hold onto one of these properties and just wait, they'll become a better investment over the longer term.

                3. The third point was that environmental design adds value. I've always known it does, but it's really great to see that reflected in the market. Getting the climate responsive design basics right is always a winner. Get those living areas facing north, the indoor outdoor living areas, so they'll be filled with light and responding to the climate, responding to the seasons, winter through summer.

                1. Firstly, if you've got design brief or budget questions, it's always worth talking to a few experienced local real estate agents to get their opinion, particularly if you're considering selling in under five years. Agents talk to buyers on a daily basis so they're in a unique position to provide information on features that add value and those that don't, as well as what buyers are prepared to pay for them. At the end of the day, it's your house, so you can do what you want. You don't have to follow the agent's advice, but I always think it's worth getting informed before you start spending any money, so there's no regrets later on.

                2. Secondly, it was interesting to find out the features of a house that add value in 2024. These vary depending on your location, but the most popular were:

                • a second living area,
                • an ensuite and walk in robe off the main bedroom,
                • a mudroom for dumping clothes and shoes and bags, etc, on the way in from the car, and interestingly,
                • a pool.
                
                

                3. The third point was that it's preferable to get advice from an agent as early in the design process as possible. This will ensure you've got clear direction forward on your design brief and most importantly, your budget, to avoid over capitalisation. Agents can provide advice on rough floor plans or even simply a discussion of your design ideas.

                KEY POINTS SUMMARY

                We covered so much information in this episode, but I just want to draw your attention to three main points.

                1. The first point was the wide range of costs to build custom, mid-range quality houses in the current market, which varied from around $3,000 up to over $6,000 per square metre.

                I predominantly work on residential renovations two storeys in inner Brisbane, which is quite sloped. So the fact that you could build on a flat block, a single story building for so much less, was quite a surprise to me.

                It was important to note what did make those renovations in inner Brisbane to older houses so much more expensive that everything is custom. Every bit of timber has to be custom cut. Everything has to fit in unusual sizes for houses out of square and that's what adds to those prices compared to the new single level building on a flat site.

                2. The second point to make is that there's no easy way to get costs down.

                There's never one or two big items that you can just take out of a job and save those costs. Costs are always spread across the entire project, so you really have to go through everything and take out little bits through the entire job.

                A better way to deal with this is when you're designing and as you go through and you choose each item, make sure you choose an item that's within your budget. Try to keep the costs down in the design stage so you don't have to go back through and take them out after costing.

                3. The third important point to note that in this market where costs are so high, it's only worth renovating houses that have got good bones.

                And this means a great piece of land that's well located, good orientation, good room sizes in the house, decent ceiling heights, limited asbestos timber doors and windows that are in good condition, and good structure.

                If this is not the case, then it may be wiser to sell.

                Alternatively, if the orientation of the land is great and the piece of land is great and you're able to remove the house, then sometimes it can be worth removing the house and building new. But it's really important to note if you are going to get rid of the house, always think of smart ways to recycle the whole house or parts of that house. You can save money and you can save the planet at the same time. Don't just send it all to landfill.

                2. Square metre rates may or may not include verandas or bits and pieces attached to the house, but they never include work outside the house.

                So make sure you allow to add all of this on to your building cost work. This includes things like driveways, cut and fill, complex footings, pools, pool houses, landscaping, fences. All of those things need to be added onto your construction cost.

                3. Both the quantity surveyor and the building cost estimator really didn't like using square metre rates because they're so variable and it's hard to get a really accurate result.

                KEY POINTS SUMMARY

                We cover so much useful information in this interview, however there are three critical points that came out of the discussion:

                1. The first point was that quantity surveyors (QS) and building cost estimators come from different backgrounds, but when it comes to residential costing they work in very similar ways.

                • Either one can provide the cost education you need. You just need to find someone local.
                • Although I did not cover it in this episode, the costs for a quantity surveyor's services are very similar to those of building cost estimator. I covered a building cost estimator’s services and costs in the previous episode.
                
                

                2. The second point was again about the critical importance of obtaining costing advice early in the design phase, to ensure your budget and design brief are aligned, before you go...]]>Did you know that a quantity surveyor can give you independent building cost advice on your house plans and ideas, and help you decide whether to renovate or sell?

                Welcome to the Renovation Collaborative ‘On the tools’ podcast, where I interview industry experts to find out practical information to help you renovate smarter. My name is Stephanie Skyring. I'm an Australian architect with 20+ years of experience helping people create better, more environmental homes on any budget.

                
                

                In the previous episode, I spoke to a building cost estimator. In today's episode, you’ll find out how a quantity surveyor can also provide you with independent building cost advice. You’ll get further insights into building costing that will add value to your residential project, whether you’re an owner, an architect, a building designer or a builder.

                
                

                I talk to highly respected quantity surveyor, Flavio Costanzo from Flavio Costanzo and Associates building cost consultants, in Brisbane.

                INTERVIEW QUESTIONS

                00:00 Introduction

                01:16 What is the difference between a quantity surveyor and a building cost estimator?

                06:42 At what stages of the design process would a quantity surveyor provide costing advice?

                11:13 Do you provide cost estimates at the tender stage for builders?

                19:06 When you are putting together an estimate, where do the material and labour prices come from?

                20:01 What are the benefits of obtaining independent building cost advice from a quantity surveyor?

                20:39 Can a quantity surveyor give advice for the whole of Australia or are they more locally based?

                KEY POINTS SUMMARY

                We cover so much useful information in this interview, however there are three critical points that came out of the discussion:

                1. The first point was that quantity surveyors (QS) and building cost estimators come from different backgrounds, but when it comes to residential costing they work in very similar ways.

                2. The second point was again about the critical importance of obtaining costing advice early in the design phase, to ensure your budget and design brief are aligned, before you go too far. Ideally this should happen at two stages:

                • First at the concept design stage when you have just got rough floor plans, to confirm your ideas are even feasible.
                • The second stage, if you proceed that far is at the detailed (developed) design stage, when you have floor plans and elevations and a bit more information. But you haven’t gone to Town Planning and you haven’t gone as far as getting full engineering done. You may have partial engineering if you need that information based on your design. This is so important, I just can’t stress this enough.
                
                

                3. The third interesting point is that both quantity surveyors and cost estimators provide costings for builders at tender stage. Many builders don’t have the time or inclination to prepare their own tender estimates. It’s important to note that all builders will have their own suppliers and buying power, and this will lead to a different final tender price outcome.

                You’ll find out all about square metre rates - What they are, how they are calculated, and why building cost professionals hate them! 

                I’ll be talking again to Quantity Surveyor Flavio Costanzo from Flavio Costanzo and Associates, Building Cost Consultants, in Brisbane.

                2. Obtaining cost advice early in the design phase is critical to ensuring your budget and design brief align.

                Preferably at two key stages:

                • Concept (Sketch Design) Stage: As soon as you have a rough floor plan to determine if your ideas are feasible. This is when you decide whether to renovate or sell.
                • Developed Design (DD) Stage: When you have more developed floor plans and elevations to ensure you are still on track. This costing must happen before you seek Town Planning Approval (if required for your site) or finalise engineering.
                
                

                This is such an important process to follow to avoid cost blowouts in this incredibly expensive construction market.

                3. For anyone obtaining a price from only one builder: The value of obtaining a cost estimate at Tender Stage to provide an essential education about what’s included (and excluded!) from your builder’s price. This should be a very open process to be discussed with your proposed builder before he prepares his tender price to ensure the costs can be compared.

                
                

                NEXT EPISODE

                  FULL TRANSCRIPT

                  Are you going in circles trying to work out whether to renovate or sell? Do you need to know more information about current costs to help you make the right decisions? Welcome to the Renovation Collaborative podcast where I demystify everything about home design and construction. I’m Stephanie Skyring

                  In my first podcast season, Renovate or Sell in Australia in 2024, I tackle costs head on. I interview five trusted industry insiders to find out the latest information:

                  • About the cost of construction,
                  • About the cost of houses
                  • About home loans, and
                  • About the right amount to borrow.
                  
                  

                  I ask the right questions to help you find the answers you need, saving you time and money.

                  The interviews follow a logical process to help you work through your cost questions.

                  I start with the current cost of house construction to help you understand what your design ideas or house plans might cost. I interview the two types of specialists who provide independent construction cost advice: a Building Cost Estimator and a Quantity Surveyor.

                  Once you have a rough idea what your design ideas might cost to build, the next step is to confirm if your ideas are feasible. I talk to a Real Estate Agent about what’s happening with the price of houses in Brisbane and all around Australia in 2024.

                  The next step is finance. Understanding the amount of money you can access is a critical first step to help you understand the size of the renovation you can build, or the house you can buy. I talk to a mortgage broker to find out the latest information about getting a home loan in Australia in 2024

                  So once you know how much you can borrow…the next question is how much should you borrow? The incredibly high costs of construction, and real estate in many Australian capital cities is leaving many people shackled to more debt than they can pay off in their lifetime.

                  In my final episode, I talk to a financial advisor about borrowing finance and how much is too much in 2024?

                  These five professionals have an incredible wealth of knowledge to help you make the right decisions. I capture their knowledge in two types of interviews:

                  1. ‘Latest info’ is covered in the main Renovation Collaborative podcasts. You’ll find out what’s going on in 2024 and 2025.
                  2. ‘On the Tools’ podcasts focus on what the featured specialist can do for you, and how to move forward with their services. I demystify the process so you can stop going in circles and start moving forward.
                  
                  

                  Action Summary At the end of each interview I wrap up the key points so you are clear on how to move forward. 

                  I’ve been an architect in practice for over 20 years, but I still learned so much in my interviews with these five experienced industry experts. I know you’ll enjoy this series whether you are a home renovator just starting out, an experienced construction industry professional or someone who simply loves learning about design and construction.

                  Join me every Tuesday and find out whether to Renovate or Sell in Australia in 2024.
