Project SummaryFume hoods keep laboratories safe and clean by removing unwanted gasses through filters and exhaust fans. But in the process, they consume considerable electricity. One laboratory fume hood uses as much electricity as three homes and produces the greenhouse gas emission equivalent of...

Project SummaryCalifornia's electrical system peak demand is growing rapidly in the residential sector, mainly because of increased air conditioner use due to increased population growth in the central valley. This project compared and evaluated three evaporative cooler technologies that could...

Project Summary:The largest energy and demand savings opportunities in residential and light commercial sectors are in cooling (47% of all peak demand savings opportunities). The use of air conditioning continues to grow in California due to increases in income, and in inland regions such as CEC...

Project SummaryTwo-stage or indirect-direct evaporative cooling technology offers the best opportunity for replacing air conditioning in California. The existing two-stage evaporative cooler on the market does not achieve the full potential of this technology. Previous lab testing has shown an...

Project SummaryThis project examines the energy efficiency potential and viability of lighting emitting diode (LED) lighting at an underground parking garage at a major hotel in San Francisco. Light-emitting diode (LED) lights are emerging as a viable alternative for outdoor locations such as...

Project SummaryReplacing the fluorescent bulbs that light frozen food and refrigerated cases in supermarkets with light-emitting diodes (LEDs) cuts electrical consumption by nearly half and results in more consistent lighting, lower maintenance costs, and longer lighting life. In this study, the...

Project SummaryThe specific objective of the study was to analyze the energy consumption of the mechanical vapor recompression (MVR) milk evaporation system at Humboldt Creamery. The results of the MVR energy consumption rate are compared to the energy consumption of typical multi-effect...

Project Summary:The Dimmable Stairwell Lighting Case Study will determine the energy usage and cost impacts of a retrofit stairwell lighting project at the Fillmore Center in San Francisco. This project will 1) calculate the pre-install energy usage, 2) calculate post-install energy usage, 3)...

Project SummaryThis project includes the design, installation, energy usage monitoring, and user/visitor satisfaction measurement for a High Color Temperature Lighting System at a demonstration site with significant target market visitor traffic. The design will demonstrate best lighting design...

Project Summary:This study evaluated an emerging technology that potentially provides energy efficiency improvements on HID lighting. The main objectives of this assessment were 1) to evaluate energy use of the emerging technology as compared to the existing technology, and 2) to characterize the...
