From 1998 to 2004, the Northwest Energy Efficiency Alliance (NEEA) managed an initiative to transform the building commissioning market in the Northwest. NEEA’s goal was to make commissioning standard practice in public buildings and to create a standardized professional certification body for commissioning providers. Through the initiative, NEEA supported the adoption of state and local commissioning policies in public buildings, and created and fostered the Building Commissioning Association (BCA). To assess the long-term outcomes of the initiative, NEEA began tracking market activities and trends related to commissioning in 2005 through its long-term monitoring and tracking (LTMT) efforts. LTMT efforts include primary and secondary data collection activities on market characterization, commissioning providers, and policy.
