Codes Market Progress Evaluation Report #4

This is the 4th 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. 

Between 2005 and 2009, NEEA fielded three MPERs evaluating the alliance’s Market Transformation efforts related to energy codes and standards, with the subsequent code-related MPER completed in 2017. Due to the period of time elapsed between this and earlier studies, the 2017 MPER was labeled as “MPER #1” at the time of its publication, with this numbering continuing with the recently completed MPER #2 published in 2024. NEEA has subsequently elected to consolidate all code-related MPERs completed to date under a consistent numbering scheme; code-related MPERs available on will be renumbered accordingly.
