Domestic hot water system electrification is a high-potential decarbonization opportunity in multifamily buildings. Based on U.S. government data, this end use accounts for 28% of multifamily residential energy consumption in the United States (EIA, 2016). Centralized heat pump water heating...

This research project was performed to support the development and implementation of California’s Title 24, Part 6 Building Energy Efficiency Standards (Title 24) by better understanding the impact of installation location and ventilation on consumer integrated heat pump water heaters (HPWH)...

This research was performed to support the development and implementation of California’s Title 24, Part 6, Building Energy Efficiency Standards (“Title 24”), to better understand the potential energy and cost advantages of dedicated outdoor air systems (DOAS) and variable refrigerant flow systems...

This research was performed to help those involved with the development and implementation of California’s Title 24, Part 6, Building Energy Efficiency Standards (“Title 24”), better understand the real-world performance of Networked Lighting Controls (NLCs) and their advanced capabilities. NLCs...

The industry is at the very beginning of the process to electrify existing large commercial buildings. Technological and financial elements of electrification retrofits remain unknown, particularly for this market segment. However, there are many recent innovations that designers are pursuing to...

Demand Response Control on Integrated Space Conditioning System Field Test Results of Integrated Variable Refrigerant Flow and Indirect Evaporative Cooling System As an activity adjunct to the California Energy Commission (CEC) project “Climate Appropriate Innovations for Variable Refrigerant...

This project aims to develop a measure package for residential windows. With the recent California Decision 23-04-035 that outlines a path for eliminating gas incentives, windows are considered a “gas exempt” measure due to providing gas savings without incentivizing a gas appliance. The California...

Abstract: This Best Practices Guide provides designers and installers of variable capacity heat pumps (VCHPs) generic information to ease the selection and installation of this equipment and improve performance and comfort. The content is derived from five years of VCHP evaluations completed at...

VEIC will investigate the potential market opportunity and decarbonization impact of installing propane-based air-to-water heat pumps (AWHPs) in residential and commercial buildings across California. Traditional heat pumps use hydrofluorocarbon (HFC) and/or hydrofluroolefin (HFO) synthetic...

California eTRM (Electronic Technical Reference Manual) already offers a statewide deemed measure for clean water pumps, providing energy savings values and a path for payment of rebates for pump replacement and improving their efficiency. However, wastewater pumps do not currently have a...
