"Thanks Sean, Yes, the color is just a general indicator. The software attributes an absorptance value to color. I generally advise that cladding is battened, providing a shading, ventilation and drainage plane. I've been arguing against thermal…"

Just after general feedback about a local Australian issue.My question is, in what situation would you advise thermal bridging though the building envelope to improve the energy efficiency of a building?Our National energy simulation software for…

"great stuff Todd. Thanks for your comment. You have obviously mastered the art of communication. My initial mistake was overenthusiastically blurting out information without noticing the blank stares looking back at me. You are right, the more jobs…"

Guess what? As much as we enjoy nerding out about building science not everyone shares our enthusiasm. This can be very frustrating when we are trying to sell our ideas and have them implemented.I was on the phone to Mark LaLiberte of Construction…

Hi Lori,
Thanks for the offer of help. We are about 20 years behind the game here.....due to going down the wrong path in a well-intended way. Very few people here know what a 'building envelope' is. It amazes, frustrates and amuses me at the same…"

Much like Hawaii most porple outside of Australia think that Australia is hot.  We actually have tropuical climate, deset climate, and temperate…"

Thanks Sydney,
I have found out a bit more about the thought process at regulatory level here since I first posted my question. The underlying issue is that they don't know how to implement air pressure testing without the physical capability to…"

Hi everyone,This is a question from Australia, (I think I’m the only Australian member of BPA).Our national building code is being updated in 2022. We currently do not address air tightness in our building code and the ‘code writers’ are reluctant…

"That's brilliant Kent.
I think Joe is on the money here. My own experience has taught me that it's not that hard to achieve around 3ACH50 for a "normal" house, and the benefeits are great. Our housing stock will improve dramatically with a sensible…"

"Thanks Kent,
It is interesting looking at the development in this area in North Ameriaca over the last 15 years or so. For the last 10 years here we have unfortunately not advanced in Australia. I remain optomistic though.
Thanks again for your…"

"Thanks very much Kent. I greatly appreciate your suggestions. I have read a lot of Joe Lstiburek's papers. I will investigate his information further in relation to air tightness.
I will also look into the IECC paper. We have Passivhaus here but…"
