> you couldn’t just take those designs and build them in anywhere in the US. This is the challenge of passive environmental design. Climate and topology make a huge difference in what works where. It's a built-in level of indirection: you can't take an effective design from Germany, and expect it to work well in Phoenix. You can take the design principles and (re)discover new pattens, but that's an order of magnitude more difficult.
