Show notes

Hello! This is Episode 430. This is Way #30 of the 44 Ways to Create Your Sustainable Home series, and we’re continuing through Section Six: Choosing Materials, Fixtures and Finishes.

In this section, I’m covering one specific criteria for choosing materials and products per episode, providing you with six different criteria overall. This episode covers the fifth criteria you can use to choose materials, fixtures and finishes with sustainability in mind.

Way #30 is: Choose from Companies with Sustainability Missions.

[For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/430]

Increasingly in other sectors, we’re seeing people make choices to spend money with businesses that are aligned with their own personal values.

They’re keen to see their spending decisions support businesses they believe in, and find companies that have missions that help create the kind of world they also envisage for their future.

This is also possible when you build or renovate, because the culture, values and mission of the companies you purchase from for your project can be aligned with your sustainable values.

And finding companies that operate like this can be a great selection criteria for the products, materials, fixtures and finishes you’re choosing for your future home.

[For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/428]

Given how much time we spend in our homes, the quality of our indoor air becomes super impactful on how our home feels.

There’s also the increasing susceptibility people can have to toxins, as well as personal values that drive them to make low tox choices in other areas of their lives.

So, it makes sense that this can be a selection criteria in making sustainable choices with the materials, products, fixtures and finishes for your home.

44 Ways #27: Choose for Low Carbon Footprint Oct 05, 2026

Show notes

Hello! This is Episode 427. This is Way #27 of the 44 Ways to Create Your Sustainable Home series, and we’re continuing through Section Six: Choosing Materials, Fixtures and Finishes.

In this section, I’m covering specific criteria for choosing the products, materials, fixtures and finishes for your future home. Last episode, in Episode 426, Way #26, I talked about choosing for longevity and durability, and the five financial costs of any material decision.

Way #27 is: Choose for Low Carbon Footprint.

[For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/427]

Selecting your interior and exterior products and materials with this in mind can be one key way to improve the sustainability of your home, especially in the impact that lower embodied carbon can have over the lifetime of your home overall.

Calculating the embodied carbon of buildings has been occurring in other parts of the industry for some time now, especially in public and commercial projects. And now, I’m seeing this be considered in residential projects as well.

You (or your team) can now do formal carbon calculations that take into account the life cycle of any products and materials you’re using in your home. This measures the carbon used in material and product sourcing, manufacture and production, transport, installation and end of life as well.

As you can imagine, this can get quite involved, so it’s great to see carbon calculators making this simpler for homeowners, and manufacturers and suppliers discussing the carbon content of their products. From low carbon products such as timber, through to innovations in high carbon products like concrete to reduce its carbon content, you have lots of options.

44 Ways #25: Include Eaves and Window Hoods in Your Finished Home Sep 28, 2026

Show notes

Hello! This is Episode 425. This is Way #25 of the 44 Ways to Create Your Sustainable Home series, and it’s the last episode in Section Five: The Building Envelope.

Over this section we’ve worked through airtightness, windows, building wraps, and insulation. In this episode, we discuss something that can elevate the performance of your building envelope very simply.

Way #25 is: Include Eaves and Window Hoods in Your Finished Home.

[For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/425]

This episode pulls together two concepts: the information about designing for the orientation of your site that I shared back in Way #1, Episode 401, our first episode of the ‘44 Ways’ series, and the discussions we’ve been having in this section about the building envelope.

Because once you understand how the sun moves across your site, the next question is about how your building envelope is designed to provide the protection you need from the elements on your site.

And that’s what eaves, hoods and awnings can provide.

44 Ways #24: Install Insulation Correctly Sep 24, 2026

Show notes

Hello! This is Episode 424. This is Way #24 of the 44 Ways to Create Your Sustainable Home series, and we’re in the final stretch of Section Five: The Building Envelope.

In the last episode, we went through the types of insulation, what R-values mean, and how to think about products for your ceiling, walls, and floor.

This episode is the follow-up to that: what happens when the product is specified, the quote is signed, and the installer shows up. Because that’s where a lot of the thermal performance of a home is either delivered or lost.

Way #24 is: Install Insulation Correctly.

[For all resources mentioned in this podcast and a free, downloadable PDF transcript, head to www.undercoverarchitect.com/424]

Did you know that a 5% gap in your insulation coverage can reduce its effectiveness by up to 50%?

So, you can invest money in specifying the right product, achieving the right R-value, choosing the right type for your climate, and testing it through modelling. And all of that work can be significantly undermined by how the product is installed.

And unfortunately, once the building is lined, any rectification becomes more challenging.

44 Ways #23: Choose Appropriate Insulation Sep 21, 2026

Show notes

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.

44 Ways #22: Review Building Wraps to Manage Moisture for Climate Sep 17, 2026

Show notes

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.

44 Ways #21: Review Your Window Selection Sep 14, 2026

Show notes

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.
