I’ve been publishing a magazine on how to make buildings sustainable since 2003.
I’m terrible at social media - it doesn’t come naturally to me - but I have a few ideas that might help.
First, we need to clearly define what we do and don’t mean by sustainable. Confusion erodes confidence. 1)

According to Sotheby's Real Estate, the hot design trend of 2024 is comfort, and the superrich are looking for "comfort, ease, and quiet luxury." But research shows that you get true comfort from warm walls, good windows, and fresh air, which is what you get from #passivhaus.

The superrich apparently are looking for "comfort, ease, and quiet luxury." Passivhaus delivers.

What happens to buildings after they're built.
Do architects care about people or do they only care about their 'art'?

…what field tests and laboratory research has been done on foam insulation:
1) dimensional stability/shrinkage over time
2) impact of joint types upon heat loss
If you know of research on this then give me pointers.
