I am off to Seattle, home of this house by NK Architects with Rob Harrison consulting, and site the Passive House Northwest conference starting Thursday night with a keynote address by your correspondent.
There are a number of TreeHugger regulars at the conference; Bronwyn Barry, seen here and in Europe here, is talking about windows and a software program at the same time as Ken Levinson (who has much to say about plastic foam in building and is always good for a lively time). Andrew Michler will join the plastic pile-on, showing how he built a foam-free passive house, not an easy thing to do. (Andrew guest-posted on TreeHugger here but is a regular on Inhabitat)
These are interesting times in the Passive House world in North America; this evening at the Bullitt Center the Passive House US organization is formally introducing their proposals for an American Exceptionalist Passive House system that differs from that used in the rest of the world. There are some interesting ideas in it, and I have have no doubt that the buns will be flying at mealtime. See more on this at MNN. I will be tweeting like mad @lloydalter.
