This roadmap effort is a continuum of the Northwest Energy Efficiency Technology Roadmap pursued by Bonneville Power Administration with the engagement of 20 collaborating organizations. The purpose of this roadmap is to explore adoption barriers and drivers associated with diffusion of variable capacity heat pump technology, and facilitate a regional consortium towards developing an energy efficiency program in the case of the Northwest, U.S. Adoption barriers are grouped under the names contractor, designer and owner related unfamiliarity; difficulty in measuring development and incentive programs; lack of information in savings and measures of cost effectiveness; and conflicting incentives and codes/standards. Policy tools and necessary action items have been developed to address specified issues by considering relevant regional efforts in an attempt to prevent duplicating the efforts already underway elsewhere.
