Hello! This is Episode 435. This is Way #35 of the ‘44 Ways to Create Your Sustainable Home’ series.

In this episode, we’re kicking off Section Eight: Sustainability During Construction.

And so, we’re going to start this section of the ‘44 Ways’ series by discussing something I wish would become standard for every single new build and potentially every renovation as well.

Way #35 is: Get a Blower Door Test.

Because, if you’re planning to create a sustainable home, your goals can come completely undone during construction.

This is largely because there is no ‘as built’ verification process inherently included in how we deliver construction of residential homes. Yes, in some locations, there are some checks along the way, but the conventional construction process doesn’t have a legislated way of proving to you that you’ve got the home you designed and specified.

However, a certified Passive House does have as-built verification requirements, and so, there are certain tests that can be adopted from the passive house methodology into traditional construction practices.

These tests can provide useful information during construction, whilst improvements and changes can still be made, to ensure you’re getting what you’re paying for in your designed and modelled energy performance. And as a result, they can uplevel typical construction to optimise what’s possible for your home.
