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...

GFO-20-303 Group 3  Address the problem of poor exterior lighting conditions in low-income and disadvantaged communities by developing, testing, and demonstrating a reliable, affordable, hybrid solar LED light that optimizes charging based on grid conditions while providing deep energy...

Demonstration platform to educate and demonstrate multiple emerging technologies for Indoor AG...

Frontier Energy will conduct a field study which will characterize the energy use of rapid cook ovens (also known as high-speed ovens) in the commercial foodservice industry. This is an emerging technology commonly found in cafes, airports, and commissaries. These ovens use a combination of a...

Outdoor lighting systems have evolved considerably in the past twenty years since the first California outdoor lighting baseline assessment project was completed in 20031. When the 2003 study  California Outdoor Lighting Assessment study was completed, LED fixtures didn’t exist in any form and...

All existing refrigeration systems operate 24/7/365 and consume vast amounts of energy to maintain the required temperature to prevent spoilage of food, medicine, flowers and industrial chemicals.  It is standard practice that all refrigeration systems are designed to maintain temperature even on...

In commercial buildings where forced-air heating and cooling systems are employed, the efficiency of ductwork plays a pivotal role in both energy management and indoor air quality.  According to the U.S. Energy Information Administration's (EIA), ventilation systems in commercial buildings consume...

Transcritical carbon dioxide (TC CO2) is emerging as the preferred low Global Warming Potential (GWP) option for commercial refrigeration systems in supermarkets and grocery stores. The unique system architecture and operating characteristics of CO2 make it difficult to model because these systems...

This project will assess pathways, technical solutions and guidance for simplified DIY homeowner or general contractor replacement of existing electric and gas water heaters with new heat pump water heaters (HPWH) in California. Permitting and code requirements for water heater installations can...

The two largest decarbonization targets in a commercial building are typically space heating and domestic hot water. Just these two end-uses account for well over 90% of the natural gas usage in most commercial buildings (excluding food service). Energy efficient, cost-effective solutions for...
