I appreciate that you don't see how a direct answer to your question, where you asked what you don't understand and it was spelled out for you, doesn't relate to the discussion.

I agree, your attempt to make the world's energy problems about the way you live personally in a Passivhaus doesn't relate to this discussion. That was kind of my point, as well as the point of several other people who've replied to you so far.

You might as well ask why everyone doesn't just live in an igloo. It's because they don't work in the places that most people live, like downtown. And if you try to ask the company "hey, I see that you claim you reduce carbon by 90%, why wouldn't LEED certify you, they only require 30%," the company will quickly change the topic.

I'll try it a little differently.

"If your solution doesn't work for 99.99% of humans, your solution just doesn't work."

No, I wasn't selling anything. This wasn't spam. But, you knew that.

I was making a good faith attempt to answer the question you asked.
