This technology increases system visibility and improves the management of building mechanical systems through better detection of events that waste energy or adversely affect occupant comfort. Building efficiency monitoring services provide the basis of a continuous commissioning process, energy...

Laboratory assessment on a walk-in cooler to measure the energy performance of drop-in refrigerant replacements for R-22 and R-404a. Testing will include testing of two alternative drop-in refrigerants with lower GWP in accordance to ASRHAE Standard...

Feasibility phase for a demonstration project with the objective is to link building energy retrofits with electric transportation system linking buildings to public transportation. To scale adoption of key technologies including energy efficiency, energy storage, distributed generation, charging...

This project will evaluate the efficacy, efficiency and operational nature of LED’s which offer color adjustability. These products are used in a range of applications but are typically selected to offer lighting color temperatures to set mode/ambiance or to balance human bio-rhythms. Testing...

ETP studies (ET11SCE1010 and ET11SCE1011) showed significant energy savings potential. This Scaled Field Placement (SFP) effort will take advantage of the Lighting Innovations project intended to test incentive midstream and upstream...

This project is the follow-up to the ETP assessment for LED Tube Replacement Lamps with an SFP that will provide measurement and verification of the installations through the limited release to the PRP area as a Custom...

The objective of this report is to calculate electric savings achieved by the fuel cell waste heat recovery absorber system installed at UCSD. The data collected from November 15th 2016 to September 11th 2017 from the fuel cell, absorber, and electric chillers were used. The data was then used to...

This report summarizes the conducted research, sources and findings. One finding is that available information is indeed not sufficiently detailed and up to date to accurately quantify power management software savings potential. A larger scale study remains nevertheless questionable, for several...

Phase One of San Diego Gas and Electric’s Digital Billboard Project “Digital Billboard Use in California: ET14SDG8011” consisted of a description of digital billboards’ technology, preliminary energy profile, and a California market characterization. The final report,...

This laboratory assessment compares the performance of low-temperature horizontal display case with natural refrigerant (propane or R-290) and conventional refrigerant...
