The goal of this project is to provide additional insight into the GAHP Tool development based on the following: -Overall daily and annual emissions savings estimates with the option to see a California-specific summary to understand the greenhouse gas (GHG) emissions impact. -A laboratory results...

Spas or hot tubs are normally used year-round, unlike heated pools. Spas typically maintain water temperatures between100-104 F which require fast heating for better customer experience. Spa heating and pool-spa configurations generally involve how the water is heated and circulated between pool...

This is an agile project idea to compare DHW sizing tools to actual site data for (9) multifamily sites. A comparison of data for (6) sites was done in ET23SWG0012 GAHP Sizing, Screening and Design. An additional (9) sites would further refine this analysis to make observations which would be...

The goal of Phase 1 of this project is to develop a tool that provides integration guidelines for emerging gas-fired commercial heat pump water heaters (CHPWH) and baseline equipment (standard & high-efficiency, tankless & storage-type) to ensure: - Ideal system configuration and component sizing,...

California hosts a significant number of data centers and telecommunication facilities, which are high energy consumers. Data centers in the United States account for over four percent of total annual electric energy consumption, and in California account for approximately two percent of total...

Motors that drive equipment such as fans and pumps, in aggregate, consume significant amounts of electricity. Pumps and fans each account for 21 percent of industrial sector electric motor energy use. Industry groups have developed test standards and regulatory agencies have developed test...

The proposed project will study early adopters of virtual commissioning (VCx) programs, a remote type of retro-commissioning program (RRCx), that focuses on HTR small and medium businesses.  A few of these programs are in the incubator and early adopter phases and are located in regional “clumps”...

This project addresses a critical market barrier: the lack of modeling tools capable of simulating distributed Phase Change Material (“PCM”) Thermal Energy Storage Systems (“TESS”) integrated with Central Heat Pump Water Heaters (“CHPWH”). Existing tools are not designed to capture the dynamic...

Micro Heat Pumps (“Micro HPs”) are efficient, rapidly deployable heat pumps that require minimal professional installation. Micro HPs are suitable for compact spaces where heat pumps can replace or displace existing air conditioners and space heating, or where traditional split or central systems...

The Clean Energy Optimization Pilot (CEOP) was authorized in 2019 by the California Public Utilities Commission. CEOP was designed to incentivize seven participating university campuses to reduce greenhouse gas (GHG) emissions through performance payments calculated based on electric and gas meter...
