An innovative contractor model of partnering with homeowners and volunteers interested in saving energy has started impacting projects throughout California. Contractors partner with homeowners and community volunteers on home electrification projects, such as installing solar PV and heat pump...

This project will demonstrate variable-speed heat pumps (VSHPs) integrated with smart electric panels that will actively manage household electrical loads, including compressor and air handler speed for the VSHP. By modulating the speed in real-time according to panel capacity and grid conditions,...

This is the final project report for a study on industrial heat pump (IHP) applications conducted from 2024 to 2025 for the Pacific Gas & Electric Company (PG&E) Code Readiness Program. This research project supports the development and implementation of California’s Building Energy...

The field assessment conducted under this project will evaluate the real-world energy performance and market adoption barriers of R-454C refrigeration systems in supermarkets. R454C is a next-generation, low-global warming potential (“GWP”) hydrofluoroolefin (“HFO”‑) blend that could serve as a...

This project builds upon the findings from previous CalNEXT projects (ET23SWE0036: Industrial Heat Pump Market Study and ET23SWE0062: Craft Brewery Industrial Heat Pump Screening Tool) to facilitate the installation and characterization of an air-to-water heat pump system (“AWHP” or the...

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...
