I heard that Belgium has mandated that all new house builds must be passive homes going forward. (very cool) Can anyone confirm or deny that? Have any other regions made that forward-thinking policy?

I spoke to a real estate agent in the US who didn’t even know what a passive house was, and after I explained it he was sure that no such house existed in his whole state. I was blown away by the gross oversight.

In another US region, someone who needed a new roof said they did an exhaustive search for a roofer who could install a vegetated roof. Not a single roofer in their city or neighboring city could do that. WTF… how are people so not on the ball at this stage?
