California has over 6,500 food and beverage manufacturing plants.  Most of these facilities use natural gas to heat relatively low-temperature hot water for cooking and cleaning requirements. Electrically powered industrial heat pumps (“IHP(s)”) can replace these hot water boilers with large energy...

This project will address barriers to heating, ventilation, and air-conditioning (“HVAC”) electrification in non-residential buildings using rooftop units for space heating and cooling. TRC Engineers Inc. and Energy Resources Integration (“ERI”) (collectively referred to herein as the “Project...

The project will evaluate the performance of heat recovery chillers (“HRCs”) paired with exhaust air coils in high-ventilation-rate commercial buildings, where the technology is especially well-suited to balance simultaneous heating and cooling loads. The evaluation will include an enhanced field...

The project proposes to develop new measure package inputs for air-to-water heat pumps (“AWHPs”) and/or heat recovery chillers as electrified successor technologies to conventional boiler and chiller systems in large commercial buildings. Building on prior market research and modeling efforts, this...

Major building envelope and duct leakage issues can occur during manufactured home production, transport, or setup; these leakage issues frequently will increase energy usage significantly and are a long-term barrier to efficient building electrification. Identifying and fixing building envelope...

The objective of this project is to support the development of a new central heat pump water heater (“HPWH”) measure package, to enable central HPWH projects where the baseline water heating system is electric (including electric resistance storage) or code minimum electric and HPWH baselines in...

This project will evaluate barriers and opportunities for accelerating the adoption of and improving energy savings associated with central heat pump water heaters (“CHPWH”) in multifamily buildings. CHPWHs typically consist of one (1) or more heat pump water heaters, hot water storage tanks, a...

Southern California Edison’s Codes & Standards Planning and Coordination (P&C) program presents their 2025 achievements and progress on key initiatives. The P&C program’s focus areas are energy-efficient building decarbonization, grid harmonization, and code harmonization. The P&C...

In 2024, PG&E’s Code Readiness Program research team initiated a research project for circulator pumps  to identify and estimate energy savings and costs for different types of controls in multifamily and non-residential buildings. The findings from this research will be used to guide...

California’s 2025 Title 24 standards advance state goals for energy efficiency, electrification, and grid readiness. However, current compliance software does not always fully reflect the benefits of core Passive House (PH) strategies. This study develops a modeling crosswalk between the Passive...
