Project SummaryThis report summarizes the installation and assessment of light emitting diode (LED) luminaires at a department store in Northern California. Relying primarily on field testing, the project team conducted photometric and power measurements, as well as retailer satisfaction surveys...

This report assesses the demand response potential from single family residential swimming pool pumps. Pool pump profiles were developed based on site monitoring data for Inland, Coastal and Desert regions of Southern California Edison service territory.The resulting profiles produced an estimated...

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 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...

Project SummaryThis research project studied the energy efficiency and power quality characteristics of power supplies used in servers. The findings revealed ways in which power consumption could be reduced, and the load capability of the servers increased. Banks of servers (also known as “data...

Project Summary:This report summarizes an LED street lighting assessment project conducted to study the applicability of LED luminaires in a street lighting application. In this project, LED lights replaced regular high pressure sodium (HPS) streetlights on several streets in Oakland, California....

Project SummaryFood processing facilities often have concurrent needs for chilling and heating water, operations that are generally provided by natural gas fired boilers and electric driven chillers. This study examines ThermoSorbersTM, combined chiller-heat pumps that provide simultaneous chilled...

Project Summary:This assessment measured the energy savings of a Mechanical Vapor Recompression (MVR) evaporation system compared to a triple effect evaporation system for the production of tomato paste. The MVR system used 89% less natural gas per pound of water evaporated than the triple-effect...

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...
