With 40-60 kWh per square foot electric usage intensity (EUI) supermarkets and grocery stores have one of the highest EUIs in the commercial buildings sector. Refrigeration accounts for roughly 50% of the electric energy and furthermore relies largely on Hydrofluorocarbon (HFC) refrigerants with...

The goal of this project is to understand the potential of heat pump rooftop unit (RTU) technology to electrify and decarbonize existing commercial building heating loads. Rooftop units are particularly ripe for market transformation as they are ubiquitous in the commercial sector with decades of...

The goal of this project is to create a resource on programs and strategies that encourage heat pump adoption in new and existing homes by targeting non-cost barriers to adoption. California has identified heat pumps as a keystone technology to its path to decarbonization and plans to prioritize...

The industry is at the very beginning of the process to electrify existing large commercial buildings. Technological and financial elements of electrification retrofits remain unknown, particularly for this market segment. However, there are many recent innovations that designers are pursuing to...

This project aims to conduct a comprehensive market study on industrial furnace applications, with a primary focus on identifying opportunities for natural gas savings. The study will explore a range of technologies, including radiative recuperators, thermal imaging, insulation, ductwork, fuel/air...

This project is a demonstration and comparison study between conventional Normalized Metered Energy Consumption (NMEC) analysis and a Measurement & Verification (M&V) method which enhances NMEC with rapid & repeatable interventions. The Enhanced NMEC (E-NMEC) with Rapid Interventions (RI) is...

A limiting factor to rapid adoption of air-source heat pumps (ASHPs) for residential retrofit applications is the first costs associated with installing a heat pump system that provides the home’s full heating and cooling loads with direct distribution into all conditioned rooms of the home. This...

A previous CEC funded project ( https://cltc.ucdavis.edu/sites/g/files/dgvnsk12206/files/media/documents/LDA-June-2022-Edit.pdf) has demonstrated the potential of a fiber optic, solar-tracking core daylight system to deliver natural lighting into the building at ~620 lumens/watt at a maximum length...

This Demand Response Emerging Technology (DRET) Voice Automation demonstration project (pilot) leveraged residential voice-assistant technology (i.e., Amazon’s Alexa smart speaker) as well as cellular telephone app functionality to engage with and educate residential customers on energy usage, bill...

Demand Response Control on Integrated Space Conditioning System Field Test Results of Integrated Variable Refrigerant Flow and Indirect Evaporative Cooling System As an activity adjunct to the California Energy Commission (CEC) project “Climate Appropriate Innovations for Variable Refrigerant...
