It is interesting to see how you do it down under. In Sweden, we generally have a vapor barrier and 45mm stud cavity for plumbing and electrics to not make penetrations in the airtight vapor barrier. But we live in a harsher climate.
It's easy to eliminate the air (and sound) leakage through wall switches and GPOs by applying putty pads around the boxes and penetrations. It's quick and easy to do. Vital if you're trying to reduce sound leakage from a home cinema room.
I'm definitely going to refer all current and future clients and friends to this video series. (They'll probably annoy some builders and trades, but its their home.) My only query is there any way to cost effectively recover the energy lost from bathroom and cooking ventilation? (Because directly exhausting conditioned air from the bathroom for up to half an hour is a lot, especially if it is going to suck in some makeup external air somewhere else in the house). ie. Would a reversible ceramic core ventilator work considering the humidity?

Blower door testing and air sealing are under appreciated.

It's a shame that there aren't a lot more views for these videos.. Way too many houses are still being poorly built in Australia.
Great series - all people building should watch - the link to SV takes you to an error page
This will be fixed next week. Sorry about that. ;)
@@ecoevo all good 👍🏻👍🏻👍🏻

What’s a putty pad? Where do you get them?

@@ecoevo nice! for the Coburg CLT passive house episode, do you know what kind of exterior insulation they were using?
@@wordle492 Andy, thanks for your contacts. I suggest you get in contact with the architect of the project. hutt.com.au. They will let you know.
R6 on those three layered attic hatch? Looks more like it will yield r18 - are r values in oz different than USA??
Where do brick ties come in penetrating the external membrane
