This Demand Response Emerging Technology (DRET) Voice Automation demonstration project (pilot) leveraged residential voice-assistant technology (i.e., Amazon’s Alexa smart speaker) as well as cellular telephone app functionality to engage with and educate residential customers on energy usage, bill...

The 2022 C&S Planning and Coordination Key Initiatives Report presents the activities and achievements of the P&C subprogram in the program’s five elements: Decarbonization, Grid Harmonization, Code Harmonization, Strategic Planning and Coordination, and Program Coordination. For the...

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...

This study will identify the electrical service requirements for various sizes of foodservice facilities such as quick serve, full service, cafeterias, and hospitality. This will help understand the costs, electrical load requirements, electrical service upgrade costs, and potential electrical load...

Adaptive daylighting controls were installed at a large cannabis greenhouse operation in central California to start exploring the potential for a deemed measure package for this technology. The amount of light needed by a specific crop during specific phases of growth is specified as the target...

This report presents and synthesizes the results of: a.) on-site assessments of Controlled Environment Horticulture (CEH) facilities in California; b.) online grower and industry surveys; and c.) a previously published CEH literature review (ETCC Report #: ET21PGE8205). The report highlights...

This is the final report for boiler research performed at UL Toronto and Intertek Cortland New York laboratories in support of publication of ASHRAE Standard 155P, “Method of Testing for Rating Commercial Space Heating Boiler Systems.” Standard 155P will rate the performance of commercial boilers...
