The Northwest Energy Efficiency Alliance (NEEA) engaged Cadmus in November 2016 to conduct the sixth market progress evaluation report (MPER 6) for NEEA’s Northwest Ductless Heat Pump Initiative (initiative). The initiative, which NEEA launched as a pilot in 2008 and at full scale in 2010, encompasses a range of activities to accelerate the adoption of ductless heat pump (DHP) technology by working with upstream and midstream market actors, promoting and supporting effective installation of DHPs in existing homes, supporting initiatives offered by Northwest utilities, and building consumer and market awareness.
