This project is a field study of a Gas Absorption Heat Pump (GAHP) water heater. The GAHP is a gas-fired technology with a technology readiness level (TRL) of 9. This project falls into phase 2F (field study phase) of a multi-phase field study pilot project for GAHP water heaters & combination...

Laundry remains a significant obstacle to decarbonization efforts of multifamily buildings in California, with limited adoption of high efficiency equipment, especially heat pump clothes dryers. In addition, most LMI households living in multifamily buildings lack in-unit laundry, increasing...

The creation of new usage load shapes is planned for PA’s (“Program Administrators”) to complete before the next CA program cycle, as outlined in the most recent DEER (“Database for Energy Efficiency Resources“) resolution. The intensive measure development period in preparation for the 2028 cycle...

Central heat pump water heater (“CHPWH”) systems and load flexibilities are an important technology to achieving beneficial electrification cost effectively to support California’s climate mitigation goals. Water heating energy use in multifamily buildings with five (5) or more units accounts for...

AESC, Inc. proposes to conduct a market study which will include a comprehensive review of vehicle-to-everything (V2X) capable electric vehicles (EVs) and electric vehicle service equipment (EVSE). The V2X application implies bi-directional (two-way) charging of an EV so that the EV may be used as...

Rural, hard-to-reach (HTR), tribal, and disadvantaged communities (DAC) face significant barriers to electrification. The market for electrification solutions in rural California is fragmented, with gaps in infrastructure, workforce, supply chain, and customer engagement. Most rural areas rely on...

This project explores the energy efficiency and load flexibility potential of smart, single-unit combination washer/dryer appliances for residential applications. Unlike traditional laundry systems with separate washing and drying units, these dual-purpose appliances integrate both functions into a...

Deemed measures rely on competing goals of accuracy and volume to ensure that the gross claims are reasonable. In the current California eTRM (electronic Technical Reference Manual), deemed measures increasingly have relied on more extensive and more complex data collection to ensure a claim...

This project aims to evaluate the performance, energy efficiency, and load flexibility potential of Artificial Intelligence (“AI”)-enabled stand-alone clothes washers and dryers in residential settings. While these smart appliances are already commercially available, their adoption has been limited...

Project OverviewTo meet California’s emissions reduction goals under Assembly Bill 1279, which mandates reducing greenhouse gas (GHG) emissions to 85% below 1990 levels by 2045, widespread electrification of residential cooking is critical. Gas stoves are a major source of indoor combustion gases,...
