David Bangs, an energy investor and former Microsoft manager, founded Home Performance Washington (HPW) in 2009 by bringing together a handful of like-minded auditors and contractors interested using a whole house energy retrofit approach to maximize efficiency, comfort, durability and safety. The group found that working together would be necessary to surmount significant obstacles and transform an industry traditionally focused on installing individual products. Today, HPW is comprised of over 80 service providers, conservation programs, educational institutions and other stakeholders statewide. HPW is, in turn, a founding chapter of Efficiency First, the national organization most responsible for federal legislation promoting performance-based home retrofits, such as the Home Star ("Cash for Caulkers") proposal in the Obama Jobs Bill. David serves as president and policy chair of HPW and as a board member and national best practices committee chair of Efficiency First.
