Water heating represents significant energy use in residential applications. Therefore, energy efficient water heating is an essential component to achieve California’s saving goals. Although gas-fired heat pump water heaters (gHPWH) have been around for over three decades, this technology has only...

This Emerging Technology (ET) study project is proposed to research emerging gas-fired water heating technologies in order to provide actionable recommendations of technologies and gaps for further study by the Statewide Gas Emerging Technologies (GET) program. This project will cover both...

This Emerging Technology (ET) study project is proposed to analyze & research natural gas water heating technology adoption trends in existing California Investor-owned utilities (IOUs) offered Energy Efficiency (EE) incentive programs, perform market research to understand technology adoption...

This project is in phase 2F (field study phase) of a multi-phase field study pilot project for gas-fired heat pump water heaters & combination systems. Phase 1 of this pilot is already underway to address initial planning and data gathering necessary for phase 2F to launch. Phase 2F plans to have...

This Emerging Technology (ET) study project is proposed to research & analyze energy efficient (EE) technology adoption trends, barriers to EE equipment adoption, and gain feedback on installed EE equipment in the commercial food service (CFS) market to provide actionable recommendations to improve...

This project will explore the feasibility and a possible approach to develop a labeling process in CA (and potentially in the USA) that would provide a uniform means to label gas appliances for use with hydrogen blended natural gas. This would allow the consumers to understand if their appliances...

This project is part of a multiphase approach to explore the controlled environment agriculture (CEA) market potential and assess individual technologies impacts on for this customer segment. The first phase of this project is a market assessment of the various technologies and applications in use...

PG&E’s code readiness subprogram strives to collect data on measures and technologies that will support more robust advocacy in future code cycles rulemakings as well as inform voluntary energy efficiency programs. Additionally, by encouraging residential builders and commercial building...

PG&E’s Code Readiness subprogram (within PG&E's Codes and Standards Program) strives to collect data on measures and technologies that will support more robust advocacy in future code cycles rulemakings as well as inform voluntary energy efficiency programs. Additionally, by...

Heat pump water heaters have the capability to heat water during off-peak times of the day and store hot water for use during times when the demand for electricity is higher. Utilizing this strategy may provide potential cost savings for occupants by reducing energy use during the highest cost...
