This project is a field study of a Gas Absorption Heat Pump (GAHP) water heater. The GAHP is a gas-fired technology and its technology readiness level (TRL) is 9. This project falls into phase 2F (field study phase) of a multi-phase field study pilot project for GAHP water heaters & combination...

This project seeks to expand the California eTRM by adding measure packages [SP1] [SP2] [PB3] [SP4] [PB5] that focus on hydronic air to water heat pump (AWHP) and heat recovery chiller (HRC) offerings. This research will also determine whether the scope of AWHP and HRC can be combined into one...

Laboratory cold storage solutions such as refrigerators and freezers are critical to keeping valuable reagents and samples safe in biotechnology, pharmaceutical, university, government, and healthcare research laboratories. High performance laboratory grade refrigerators and freezers are designed...

This Flexible Load Technical Potential project is exploring the expected growth in electrification technologies and estimating the effect on residential, small commercial, and medium commercial customer load profiles as well as estimating the technical potential of flexible load as these load...

This study aims to characterize the hydrogen fuel blending performance (up to 30% blend) of a Robur Gas Absorption Heat Pump (GAHP)-A unit to sufficiently populate model inputs in EnergyPlus. Gas Technology Institute (GTI) Energy will serve as a contractor for this study. They will develop a test...

The existing commercial foodservice (CFS) measures offered in California (CA) incentive programs are the most common pieces of equipment for this industry. Many of these measures will be considered for appliance code standards in the coming years or removed from programs due to the gas incentive...

Central heat pump water heating systems (CHPWH) are crucial for the greenhouse gas, decarbonization, and energy efficiency goals of California. This technology is relevant to a large portion of the multifamily and commercial building market and the earliest adopters are beginning to install these...

Water heating accounts for 40 percent of natural gas consumption in the residential sector, representing 7 percent of the state’s total GHG emissions (E3 2019). Water heating energy use in multifamily buildings with 5 or more units accounts for 32 percent of total energy use based on a 2015...

The California Investor-Owned Utilities (CA IOUs) analyzed validated datasets of performance data for electric pumps, motors, and compressors collected as part of Measurement and Verification (M&V) of custom incentive programs for these types of equipment commissioned by the California Public...

Standard designs for large commercial buildings rely on separate gas-fired hydronic heating and chilled water loops. This technology has slowly been refined with incremental energy efficiency improvements over several decades. The HVAC industry has not yet had enough time to establish how to serve...
