The 120V heat pump water heater (HPWH) has the potential to vastly increase customer adoption of heat pump water heaters by reducing installation costs. The 120V units plug directly into existing shared or dedicated circuits at the WH location, eliminating additional electrical wiring and/or...

Water heating represents significant energy use in residential applications. Therefore, energy efficient water heating is an essential component to achieve California’s saving goals. Although gas-fired heat pump water heaters (gHPWH) have been around for over three decades, this technology has only...

This Emerging Technology (ET) study project is proposed to research emerging gas-fired water heating technologies in order to provide actionable recommendations of technologies and gaps for further study by the Statewide Gas Emerging Technologies (GET) program. This project will cover both...

This Emerging Technology (ET) study project is proposed to analyze & research natural gas water heating technology adoption trends in existing California Investor-owned utilities (IOUs) offered Energy Efficiency (EE) incentive programs, perform market research to understand technology adoption...

This project will test GoPowerEV, a new electric vehicle (EV) charging solution designed to provide access to charging in existing multifamily buildings with limited electrical capacity. GoPowerEV's combination of power-sharing capabilities, built-in load shifting, scalability, and affordable...

Supplemental lighting in greenhouses uses significant electricity, and lighting controls that regulate supplemental lighting based on the amount of natural light available should be encouraged in the market. This project would extend a study currently being done by PG&E on the potential for...

Residential heat pump space conditioning and water heating can greatly reduce energy consumption compared to typical natural gas combustion or electric resistance equipment. Multi-function heat pumps are a product type that uses one efficient outdoor compressor and heat exchanger unit to provide...

The persistence of Covid-19 and remote work is driving new patterns of variable and unpredictable occupancy in commercial offices, where work flexibility is the new norm and employees may go to the office irregularly or infrequently. In many instances, this may become the new norm. As a result,...

AESC proposes a market evaluation study of solar assisted heat pumps, a technology that promises to provide supplemental, carbon-free heating to any variable-speed pump air conditioner in the 2-ton to 10-ton range – and thus is applicable to residential split heat pumps and small commercial split...

Currently, incentives for energy efficient water heater retrofits require a like-for-like replacement. However, there is anecdotal evidence that contractors upsize heat pump water heater replacements relative to existing gas water heaters. This project adds to current statewide water heating...
