Heat pump space conditioning and water heating can greatly reduce energy consumption compared to existing electric resistance or natural gas combustion options. Requirements for electrical service upgrades add cost and installation delays for customers considering heat pumps for space conditioning...

Using swimming pools as heat sinks for air conditioner waste heat has been estimated to reduce air conditioner energy use in California by 25-30% (Harrington and Modera, 2012). There are two primary advantages of rejecting waste heat to an air conditioner instead of ambient air: 1) swimming pool...

The majority of building power distribution systems use alternating current (AC). This significantly influences the design of connected, building system components and appliances such as direct current (DC) appliances. With the proliferation of DC devices as standard design elements across many...

The proposed project is a laboratory evaluation of advanced home energy management systems (HEMS) that will quantify the electrical efficiency associated with advanced distributed energy resource (DER) management features and assess claims of interoperability across a range of communication...

This Focused Pilot project will identify and address the comprehensive set of barriers associated with the purchase and installation of commercial high-efficiency condensing units (HECUs) and high-efficiency evaporator units (HEEUs) used in walk-in coolers and freezers and remote condensing...

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 California Low-Income Residential Housing Characteristics Study project proposes to address the lack of complete data on housing structures in disadvantaged communities (DAC) and Hard-to-Reach (HTR) single family residential housing. While high level data such as number of homes in DACs and...

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...

Flick Power is interested in a pilot to test the effectiveness of its communicating light switch technology that displays signals to residential consumers about the price of electricity.  While customers may have been transitioned to TOU rates, many do not know the hours that electricity is most...
