The project will consist of an assessment of energy and non-energy impacts of moderate-low GWP refrigeration design on three newly constructed supermarkets. Each of the supermarkets will be newly opened and operating as of August 2020 with low-GWP (less than 150) and moderate-GWP systems (less than...

The project will consist of an assessment of energy and non-energy impacts of low-GWP retrofits on three supermarkets. Each of the three supermarkets are scheduled to upgrade their existing systems, replacing traditional HFC refrigerants with low-GWP (less than 150)  and reduced charge moderate-GWP...

The proposed project is an extension of an existing SCE EP project being implemented that is designed to enhance grid reliability, replace high GWP refrigerants with ammonia and/or carbon dioxide, improve efficiency, process optimization, and achieve decarbonization goals at a large bakery site....

This project evaluates the performance of a production prototype residential three-function heat pump (TFHP) system. TFHPs are called “three function” systems as they utilize a single compressor to serve indoor heating, indoor cooling, and domestic hot water loads. The system evaluated in this...

The California Air Resources Board and Southern California Edison recognized the need for robust primary research among key decision-makers to help California achieve the state’s ambitious climate goals – specifically through the adoption of zero-emission appliances such as heat pump water heaters,...

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...
