The Northwest Energy Efficiency Alliance (NEEA) contracted with Ecotope to conduct a feasibility study of domestic hot water systems that integrate commercial electric heat pump water heaters and natural gas water heaters, primarily in multifamily buildings. The study examined the technical feasibility, gas savings potential, market opportunity, design considerations, and regulatory requirements associated with these dual-fuel systems. …

The Northwest Energy Efficiency Alliance (NEEA) contracted with Kannah Consulting to evaluate whether the U.S. Department of Energy’s current clothes dryer test procedure (Appendix D2 to 10 CFR Part 430) accurately predicts dryer energy use under real-world operating conditions. The study assessed 12 top-selling electric clothes dryers representing three efficiency groups: non-qualified, ENERGY STAR® qualified, and heat pump models. Each…

Recorded July 14, 2026 – Adding energy storage to buildings not only saves energy, energy costs, water and carbon, but it now gets a boost with substantial federal tax incentives. Presentation covers innovations, challenges, and opportunities in the transition to electrified heating systems using thermal storage. Several system choices will be reviewed from a high-level…

The Regional Emerging Technology Advisory Committee (RETAC) held their second quarterly meeting of 2026 on June 17th. Topics included a review of the research around heat pumps conducted by the Electric Power Research Institute, as well as an overview of current projects by the Emerging Technologies Collaborative (ETC), which is part of the Consortium for…

The Commercial/Multifamily HPWH Systems QPL contains information on Commercial and Multifamily products that meet the Advanced Water Heating Specification requirements. These products generally serve more than four dwelling units or a commercial load (as defined in the specification). Products can be integrated or split systems. Please contact us with any questions. Updated as of 2026 – Version…

The Q2 committee meeting will focus on key regional heat pump initiatives, including a review of draft resources from the NW Heat Pump Symposium, NEEA’s proposed draft of the Advanced Heat Pump specification highlighted at Efficiency Exchange, and discussion on the RTF’s “Minimizing Supplemental Heat” measure development, facilitated by Sr. Program Manager Suzi Asmus. The…

Commercial Secondary Windows (CSWs) are retrofit glazing systems installed on the interior or exterior side of existing windows in commercial buildings. They are designed to improve energy efficiency and occupant comfort while reducing sound transmission and air leakage, all without requiring the expense and disruption of full window replacement. Secondary windows typically consist of an…

The Northwest Energy Efficiency Alliance (NEEA) contracted with Cadmus to review the naturally occurring baselines1 for ENERGY STAR® clothes dryers and heat pump clothes dryers. The study also explored whether separate baselines should be developed for clothes dryers based on drum sizes (compact or standard). Methods included a review of NEEA documentation, secondary research, and interviews with three clothes dryer market experts.   Report findings suggest that no…

Market Transformation begins with identifying new ways of providing the same or better services at low net cost. Jigar Shah will cover his experience that began with developing SunEdison to enable customer participation in virtual power plans, his work for the DOE setting up energy loans for new technologies and businesses, and the latest challenges…
