The main objective of this project is to install a CarbinX unit at a pool heater boiler at a hotel in Los Angeles and test and quantify the carbon dioxide emissions reduction, fuel savings, waste heat recovered, and energy savings. The CarbinX unit will also operate as a Direct Air Capture (DAC)...

AGILE: There is a push for electrification of most gas end uses including commercial cooking. The results from GET Study ET23SWG005: Dual Fuel Single Family Modeling indicated that running an electric heat pump to heat a single-family home would cost anywhere from 68% - 144% more than a gas furnace...

On October 10, 2023, the U.S. Department of Energy (DOE) published a Notice of Proposed Rulemaking (NOPR) and Technical Support Document (TSD) for Energy Conservation Standards for Commercial Refrigerators, Freezers, and Refrigerator-Freezers (CRE). To support DOE’s CRE standards rulemaking, the CA...

Unlike the single-family residential market where a one-size-fits-most approach to HPWH systems is feasible, multifamily water heating systems require more varied designs targeted at specific building types and sizes. Design possibilities are myriad, beyond mere equipment selection, but many...

The two main goals of this research project were (1) to validate ASHRAE Standard 195 “Method of Test for Rating Air Terminal Unit Controls” as a reasonable and fair method for evaluating the controllable minimum of VAV boxes and VAV box controllers and (2) to use Standard 195 to determine the...

This is a field study which is the second phase of a market and technology study for natural gas efficiency technologies for controlled environment agriculture (CEA). The CEA and Greenhouse HVAC Market and Technology Study (ET23SWG0003) and completed in 2024 characterized California's CEA market...

This study aims to characterize the hydrogen fuel blending performance (up to 30% blend) of a second Gas Absorption Heat Pump (GAHP) 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 plan...

AGILE: The GET program recently completed project ET23SWG009 to test and quantity the emissions and efficiency improvements of an emerging burner technology as a boiler burner retrofit. The ClearSign Core™ technology is an innovative gaseous fuel combustion technology designed to significantly...

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

Temperature maintenance losses often account for around 30% of total thermal loads in centralized domestic hot water systems in multifamily buildings (but can be as high as 60%). Correction of these omnipresent recirculation inefficiencies in high-rise multifamily buildings has direct implications...
