Which house belongs to the environmentalist?

huh, it only states that things where installed there, not who recommended them, but if you keep reading on it talks about how David kept having to limit what the Bush’s wanted, how ever he lost a few and won a few. Having worked on some of David’s work he is a genius when it comes to green buildings.

Or are you talking about this pasage

Karen P. Hughes, counselor to the president, said, Bush has put in place “responsible environmental policies” at his 1,600-acre ranch. “He has installed a very environmentally friendly heating and cooling system, and he has put in place a system to recapture groundwater.”

Which basically says he has it, but not who is the one who wanted it.
