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...

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 document is a report on the Southern California Edison (SCE) Codes and Standards (C&S) Planning and Coordination (P&C) subprogram key initiatives for 2023.  The P&C subprogram aims to support California's energy transition and decarbonization goals by coordinating and...

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...

The intent of this Focus Pilot is to break down barriers to residential heat pump water heater (HPWH) adoption in the marketplace. We target four of the most significant barriers to test for scalable solutions that will result in faster time to market for HPWH. Those barriers are 1) Higher first...

The proposed idea is to provide recommendations for updates around adding plug-in 120-volt heat pump water heaters (HPWHs) for inclusion into existing residential HPWH related eTRM measure packages.   The 120-volt HPWHs are market-ready and proven to be important new offerings. It is estimated...

The proposed project involves field demonstration and evaluation of an emerging technology, which is micro-zone control for ducted variable air volume (VAV) systems in medium to large commercial buildings. The technology is the only commercially available product in the U.S. today that can be added...

This focused pilot aims to increase the adoption of Commercial Packaged Unitary Heat Pump systems (Commercial HP RTUs) ≥ 5.4 tons through a streamlined midstream pilot program. While Commercial HP RTUs have been on the market for decades, adoption in CA is lower than expected given the generally...

Industrial processes are one of the more difficult sectors for electrification and energy efficiency measures due to the high capital costs and risks of implementing new technologies. While less known, emerging microwave technologies can be a process heating solution for a variety of industrial,...

This project is an Emerging Technology Field Demonstration to evaluate the efficiency, cooling performance, and load shifting/demand flexibility, of a liquid desiccant- enhanced commercial packaged rooftop unit with integral energy storage. This tests a new class of equipment referred to by the US...
