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...

In 2021 PG&E’s Code Readiness Program research team (research team) initiated an evaluation and data collection of nonresidential hydronic heat pump heating equipment across California. The intent of the data collection effort was to better understand how hydronic heat pumps perform under...

This study aims to investigate a fuel-fired Thermal Heat Pump (THP) technology to assess its uniform efficiency factor (UEF) potential. The Gas Technology Institute (GTI) Energy will serve as the subcontractor for this study. The THP concept is a gas-driven ammonia adsorption heat pump water heater...

The California Investor-Owned Utilities (CA IOUs) analyzed the applicability and effectiveness of the National Electrical Manufacturers Association (NEMA) MG 1 Part 34 Test Procedures for Totally Enclosed Air-Over (TEAO) motors. TEAO motors are a specific type of motor used in heating, ventilation...

Frontier Energy will conduct a field study, which will characterize the energy use of high-speed ovens (also known as rapid cook ovens) in the commercial foodservice industry. This is an emerging technology commonly found in cafes, airports, and commissaries. These ovens use a combination of a...

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 retrofit heat pumps. Anywhere from...

Outdoor lighting systems have evolved considerably in the past twenty years since the first California outdoor lighting baseline assessment project was completed in 20031. When the 2003 study  California Outdoor Lighting Assessment study was completed, LED fixtures didn’t exist in any form and...

All existing refrigeration systems operate 24/7/365 and consume vast amounts of energy to maintain the required temperature to prevent spoilage of food, medicine, flowers and industrial chemicals.  It is standard practice that all refrigeration systems are designed to maintain temperature even on...

Current California Public Utilities Commission CPUC regulations limit the use of Normalized Metered Energy Consumption (NMEC) as a savings platform to three use cases: commercial buildings, industrial sites enrolled in a Strategic Energy Management (SEM) program, and industrial sites with...
