A school in Reidberg, Germany, built using the passive house approach

I got back yesterday from the 13th Annual Passive House Conference in Frankfurt, Germany. My biggest takeaways from the conference are:

• While the growth of passive houses in Europe is impressive, even in Europe there are still marketing challenges
• The opportunity to use energy efficient buildings as a hedge against climate change is immense
• We are way behind on energy efficient building here in the U.S. – in fact, essentially no one in the U.S. is doing this kind of building.
