Passive house and others of this design get all the heat and hot water they need from the amount of energy that would be needed to run a hair dryer

I have just finished Hot, Flat, and Crowded by Thomas Friedman, it was a very interesting book. Today the NY Times has an article titled No Furnaces but Heat Aplenty in 'Passive Houses'

From the outside, there is nothing unusual about the stylish new gray and orange row houses in the Kranichstein District, with wreaths on the doors and Christmas lights twinkling through a freezing drizzle. But these houses are part of a revolution in building design: There are no drafts, no cold tile floors, no snuggling under blankets until the furnace kicks in. There is, in fact, no furnace.

In Berthold Kaufmann’s home, there is, to be fair, one radiator for emergency backup in the living room — but it is not in use. Even on the coldest nights in central Germany, Mr. Kaufmann’s new “passive house” and others of this design get all the heat and hot water they need from the amount of energy that would be needed to run a hair dryer.


I wonder how that would work in Princeton where I live, we sometimes get 100 degrees Fahrenheit and 95% humidity in the middle of the summer. Could that house cool itself in that kind of heat? I doubt it.
