The International Living Future Institute (ILFI), owner of the Living Building Challenge, is going where no certification program has gone before with a new Net Zero Energy Building Certification program (BuildingGreen.com).  You can read the International Living Future Institute press release on the NZE Building Certification program here.  There is a zero net energy gas station in Beaverton, Oregon (OregonLive.com).  KB Home, one of the largest homebuilders in the U.S., has developed ZeroHouse 2.0, a house designed to achieve net-zero energy. The home is currently available in Tampa, Florida, and in San Antonio and Austin, Texas, but the company plans to expand the availability of net-zero options to other cities throughout 2012 (BuildingGreen.com).
