This is the first Market Progress Evaluation Report (MPER) of the Northwest Energy Efficiency Alliance (NEEA) Codes Program. Since 1997, NEEA has conducted activities to support building energy codes and has funded several studies of these activities. In 2010 and 2011, Cadmus researched the program’s code support activities, logic model, and the building codes market. NEEA’s current code efforts focus on three distinct, but interrelated, code support stages—development and adoption, implementation, and compliance—and this study assesses the Codes Program activities since 2011 in each of these stages.
