Are most homebuyers interested in purchasing a home that saves 90% over a traditional home on heating and cooling costs and requires only a small active heating system the size of a hairdryer? The Passivhaus movement is an exciting building design concept that offers tremendous energy savings due to reliance on passive heating systems. Europe is embracing the concept with between ten and fifteen thousand houses already built and governmental support of mandating the standard. The Passivhaus Institut in Darmstadt was formed in 1996 to promote and control passive house design and the group only recently formed the Passive House Institute US (PHIUS) to reach out directly to the US building market. It is slow to gain momentum, but holds promise for the US market in the future.
The Solar Decathlon is a competition in which teams of college and university students compete to design, build, and operate the most attractive, effective, and energy-efficient solar powered house. The winners of the 2009 competition – the fourth to be held – were announced on the National Mall in Washington, D.C. by U.S. Department of Energy Deputy Secretary Daniel Poneman. The contest is organized by DOE’s National Renewable Energy Laboratory and supported by event and team sponsors from the private sector.
