5 Principles Of A Healthy Home 31.08.2018 1:08:59
Health is the new green - this message is seemingly everywhere these days. It's clear that a shift is underway in the way we think about our homes and buildings. A quality building does more than just use energy efficiently, it needs to provide for the occupants. This means recognizing that our clients will spend their time immersed in the air we create for them and that indoor air is a dominant e...

Inside The Mind Of An HVAC Contractor (Or Two) 27.07.2018 1:07:16

Locavore Dirt Construction? 13.07.2018 59:12
Through the years, we've been asked a lot about natural building materials and how they relate to building science. And frankly, it's a nuanced conversation that requires a lot of unpacking preconceived notions about what constitutes a good product (from the perspective of liability, ecology, availability, serviceability, durability, etc.). In this episode of the podcast, we interview Brad King of...
Use Your Tools - The New COTE Tool Kit 29.06.2018 1:08:08

Welcome To The Filtration Station 15.06.2018 50:57

Who knew there was so many impor...
Let's Get Legal-ish 01.06.2018 1:02:55
When we think about building science, we're thinking about systems and the unseen forces that contribute to the success or failure of a building.

Dirty Socks & Your HVAC Coil 04.05.2018 44:48

Fortunately for us, we got to catch up with Greg for a more in depth discussion. So what do dirty socks have to do with the...

Our Homes, Our Health 06.04.2018 57:21
It's normal these days to pay attention to what we eat. But what about the steady diet of air we breathe and soak ourselves in? The impact of homes on health somehow manages to stay below the radar.

Design & Construction In Humid Climates 26.01.2018 29:36
Yes. We're going to have a chat about humidity. If you live in a heating dominated, dry climate you might be thinking "what good is this for me to hear?" and I wouldn't blame you.

In this episode of The...
