The Northwest Energy Efficiency Alliance (NEEA) contracted with The Cadmus Group, Inc. (Cadmus) to conduct a study of residential energy code compliance in the state of Washington. This effort to measure compliance has roots in the 2009 American Recovery and Reinvestment Act (ARRA), which provided funding to states, contingent upon a commitment to adopt the latest model energy codes, and to develop and implement a plan, including active training and enforcement provisions, to achieve ninety percent compliance with target codes by 2017. This commitment also included measuring current compliance each year.
