This is the final project report for a study on steam trap fault detection and diagnostics (FDD) conducted from 2023 to 2025 for the Pacific Gas & Electric Company (PG&E) Code Readiness Program. The purpose of the study was to investigate the impact and feasibility of extending the 2022...

This proposed project aims to address the increasing demand for datacenters driven by the rise of Artificial Intelligence (“AI”), machine learning, and cloud computing. In California, Pacific Gas and Electric Company (“PG&E”) estimates an additional three and a half (3.5) giga-watts (“GW”) of...

The PG&E HVAC Tool, developed to estimate savings for retro-commissioning (RCx) measures in commercial buildings pursuing utility incentives in California, has faced limited adoption due to the need for additional validation and California Public Utilities Commission (CPUC) approval. To address...

This memo summarizes the endangered savings analyses conducted by the Pacific Gas and Electric Company (PG&E), San Diego Gas and Electric (SDG&E), and Southern California Edison (SCE), collectively referred to herein as the California Investor-Owned Utilities (CA IOUs), in response to the...

This report marks the third annual publication highlighting key initiatives of the SCE P&C program in its five focus elements of decarbonization, grid harmonization, code harmonization, strategic planning and coordination, and program coordination.  Key initiatives to advance technology...

In 2024, PG&E’s Code Readiness Program research team initiated an energy modeling research project for elevators in commercial and multifamily buildings. The intent of the energy modeling research was to provide a clear methodology and dataset that would help inform developing a CASE measure...

This study aims to provide additional system performance testing for a prototype dual fuel hybrid heat pump for the residential sector. Developed by a major OEM, this 120 V heat pump is equipped with a gas combustion burner to maximize efficiency and performance. This eliminates the need for...

The American Society of Heating, Refrigeration, and Air-Conditioning Engineers (“ASHRAE”) Guideline 36 High-Performance Sequences of Operation for heating, ventilation, and air conditioning (“HVAC”) Systems is considered the best-in-class control sequence in the industry. Several California Energy...

This research project supports the development and implementation of California’s Building Energy Efficiency Standards Title 24, Part 6 (Title 24) by providing insights into envelope and thermal energy storage (TES) design strategies along with their potential energy savings. A significant...

This research project was designed to introduce strategies that reduce and manage building peak electric demand to those involved with the development and implementation of California’s Title 24, Part 6, Building Energy Efficiency Standards. A key challenge and barrier in the transition to a fully...
