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...

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 retrofitting heat pumps for space...

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...

In January 2022 we completed a laboratory study (ET19SCE1110) on the proposed air vane technology under contract with the SCE ET&P group to investigate the benefits of installing air vanes on vertical open refrigerated display cases used in grocery stores.  In the lab assessment, a reduction of 17...
