Get It Right with Undercover Architect

Hello! This is Episode 423. This is Way #23 of the 44 Ways to Create Your Sustainable Home series, and we’re continuing through Section Five: The Building Envelope.

Way #23 is: Choose Appropriate Insulation.
[For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/423]
The things we’ve been discussing in Section Five are all about improving the energy efficiency of your future home, whilst also supporting its durability, longevity, and the contribution it makes to your health and well-being in your home, through the choices in how you assess, test and specify your building envelope.
Over the past few episodes, we’ve covered airtightness, window selection, and how to choose the right building wrap for your climate. This episode is about insulation: the various types and what to know about how it works.
Insulation has been part of home construction for decades, and as energy efficiency benchmarks have become part of building and renovating, insulation has been adopted as a worthwhile investment to help reduce the cost of heating and cooling homes.
We’ve done a great job of improving the insulation in our homes over the years, understanding it improves our home’s thermal performance.
But how much insulation do you really need? And where, and what type?
In this episode, I share more with you as we go through why insulation matters, what to measure and consider, why adding more insulation may be counterproductive, and how to think about the roof, ceiling, walls and floor of your home for the best outcome.

Hello! This is Episode 422. This is Way #22 of the 44 Ways to Create Your Sustainable Home series, and we’re continuing through Section Five: The Building Envelope.
In the last two episodes, we covered thermal mass and window selection. Before that, in Way #19, we talked about what building tight actually means: why you want a continuous air barrier, and why airtightness and ventilation have to be designed together. This episode is about a layer that sits within the wall and roof assembly of your home: the building wrap.
Way #22 is: Review Building Wraps to Manage Moisture for Climate.
[For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/422]
Historically, especially in Australia, we’ve seen foil sarking act as this layer.
However, with learnings over time about how this has detrimentally affected the performance of the building envelope, as well as how it has trapped moisture inside the wall, bringing issues such as mould and rot, better products are now available to do this job.
Yet, the industry isn’t up to speed with this, and in some cases, is still installing the wrong building membranes, and using the wrong detailing, which continues to create long-term issues.
Getting it right with building wraps involves knowledge of building science and construction detailing, and your climate and construction methodology is key to ensuring the best solution for your project.
So, what I’m sharing in this episode will get you started, but it’s super important to be discussing this in detail with your team. Don’t assume that, just because it’s in the local building regulations, your team is across it.

Hello! This is Episode 421. This is Way #21 of the 44 Ways to Create Your Sustainable Home series, and we’re continuing through Section Five: The Building Envelope.
Way #21 is: Review Your Window Selection.
[For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/421]
In my experience, as people go to design their new build or renovation, it can be all about maximising the indoor / outdoor connection, and having a home that feels light-filled and expansive.
And so, the glass windows and doors you choose, in their size, arrangement, design, functionality and type, all become really important decisions in achieving this in your home.
And, they’re likely to take a big chunk of your building budget.
However, glass windows and doors are also where the majority of uncontrolled heat gain and heat loss happens in a home. They sit at the intersection of the envelope performance issues we’re covering in this section: thermal performance, ventilation, airtightness, and moisture management.
And yet, most homeowners haven’t been given the information they need to make deliberate choices about them.
In this episode I focus on the envelope performance side: thermal properties, airtightness, and ventilation. Because when you’re thinking about your glass windows and doors, you’re possibly not asking questions about these things, and they’ll make the biggest difference to how your home performs.

Hello! This is Episode 420. This is Way #20 of the 44 Ways to Create Your Sustainable Home series, and we’re continuing through Section Five: The Building Envelope, A Sustainable Skin.
In the last episode, Way #19, we covered airtightness and ventilation. We talked about what it means to build tight, why homes don’t need to breathe, and what ‘ventilating right’ looks like in practice.
In this episode, we’re looking at one of the most commonly discussed, and commonly misunderstood, elements of the building envelope: thermal mass.
Way #20 is: Use Thermal Mass to Maintain Even Temperatures.
[For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/420]
You’ll hear architects, builders and sustainability consultants talk about thermal mass as a worthwhile inclusion in any home. This can include concrete slabs, brick walls, rammed earth, and other ‘heavy’ forms of construction.
Even water-filled features are used as thermal mass in homes.
Thermal mass is a powerful tool when the conditions support it, and it’s designed with the right approach for the climate and site. However, when those conditions aren’t in place, it can make your home harder to heat, harder to cool, and less comfortable overall.
In this episode, I take you through what thermal mass actually is and how it works, the three conditions that need to be in place for it to function well, when thermal mass will work against you, why the ground your slab sits on and the finish that covers it matter just as much, and what to ask your team.
