Ready or Notcomments (1) February 25th, 2010 in Blogs
How many of you, standing back 10 –to– 15 years ago, would have imagined the total conversion in the building industry, not only accepting, but embracing and even championing green causes? I am currently attending the Residential Energy Services Network's, otherwise known as RESNET® Conference in Raleigh, North Carolina.
Along with interest in all the government stimulus money aimed at energy remodeling, I see lots of genuine interest in formally far out concepts like the Passiv Haus. What’s Passiv Haus? It is German for, well… “Passive House,” and refers to a method of building zero-energy consuming homes developed in Darmstadt, Germany, back in 1990, when green was still a fringe thing in the USA (remember tree hungers and eco-terrorists?).
Fast forward twenty years, and the US Department of Energy (DOE) has firmly established a program to entice, and challenge America’s mainline homebuilders to construct net zero energy homes. The Builder’s Challenge, a program started during the Bush years, and similar, but not as radical as Passiv Haus, has already stimulated the construction of about 2,500 net zero homes as of February 2010. It focuses on residential. The Passiv Haus program includes buildings from homes and hotels to US army barracks (the U.S. army was among the to embrace the Passiv Haus concept for its German bases) that have no connection to the power grid by virtue of designing the building to exploit natural light, radiant heat, convection cooling, and, of course, alternative energy.
