I love that prototype, I was inspired in part by the fact that almost all saab vehicles have quite a nice slope to the rear window! Very cool photo you posted there.
The Passive Haus concept is something I was reading about, so yes essentially net-zero / passive haus techniques are very similar. The two books I read most recently were:
- Green From The Ground Up
- Toward A Zero Energy Home
By: David Johnston & Scott Gibson
Great reads, kinda the same book.. but one covers houses which employ the techniques for producing their own energy and being self sufficient, and the other talks about the different systems in a bit more detail.
