NYTimes article on "passive houses"

Very interesting article on another generation(?) of green-building technology in today's NY Times. "Passive houses" are increasingly popular in Germany and they sound like a great idea. The idea is to build an airtight structure with tons of insulation such that it can be kept warm by a body heat and the heat put off by lights, etc. It doesn't need a furnace because it stays warm enough on its own. The biggest challenge was maintaining fresh air in the house and they figured out how to do that via a heat exchanger system. Worth the read and further research.

It's exciting to see new innovation that will likely have huge positive impacts on our way of life.
