Seen (and drooled on) parked in front of the Cleveland Museum of Art:
This is the PNC SmartHome.
It's around the curve from the Museum of Art and is for sale. They were holding open house and selling off the furnishings while we were there so we looked at it, too. It's a lovely home, but it does demonstrate one of the major problems with green building. While touring it the salesman told me it cost $500,000. to build, but they were asking $350,000. They started at $400,000. but have come down on the price, and still no takers. No wonder more people don't build this way.
