The Study’s goal was to investigate whether Title 24 energy code compliance requirements and energy simulation rulesets for RTU/economizer systems adequately reflected real world performance in California climate zones and make recommendations based on the investigation findings. The Study...

For four years (2015 to 2018) one of the Central Valley Research Homes (CVRH) in Stockton, CA has been used to evaluate radiant ceiling panel systems in a residential application. The radiant ceiling panel systems tested consists of two brands of panels. In addition, four air-to-water heat pumps...

Convenience store field evaluation of AI-based technology to evaluate its efficacy for broader customer segment in SCE’s service territory. Specifically, EPRI proposes to lead the field evaluation for Measurement and Verification of technology for power reduction (demand savings) and GHG...

This study evaluated the performance of unitary heat pump water heaters (HPWHs) operating in a shared configuration (each unit served four apartments) in an affordable all-electric multi-family project located in Davis, CA. The shared configuration allowed the HPWHs to be placed in close proximity...

PG&E’s Demand Response Emerging Technology (DRET) group initiated a Battery Study to investigate the ability to utilize residential photovoltaic solar systems paired with a Tesla Powerwall home battery systems to support state electric grid reliability in times of high electricity demand...

This project will help determine the effectiveness of Phase Change Materials (PCMs) in cold storage applications at Low Temperature -10 - 0 F (-23 - 18 C). Controls will also be implemented into the study to determine how compatible it is with PCMs. A total of 4 tests will be done on warehouses to...

San Diego Gas and Electric (SDG&E) contracted with Demand Side Analytics (DSA) to conduct analysis and develop tools to target Demand Response (DR) programs, behind-the-meter (BTM) battery storage, and distributed solar. The team designed the research tool to inform customer targeting and...

The craft brewing industry has experienced tremendous growth over the last 10 years and California—particularly San Diego—has been at the forefront of this wave. Unlike large breweries, small and mid-size craft breweries do not have the resources to dedicate to optimizing energy...

The study assessed the potential to leverage Electric Vehicle (EV) Automated Demand Response (ADR) charging technologies through the Demand Response Emerging Technology Program (DRET) from 2020–2021. It analyzed interval data from 71,000 EV customers in PG&E’s service territory to...
