Project SummaryThis report summarizes the installation and assessment of electronic HID at a regional supermarket chain location in Northern California. Relying primarily on field testing, the project team conducted photometric and power measurements, as well as customer satisfaction surveys and...

Project SummaryThis project analyzes and tests the integration of night ventilation cooling technology into a standard heating, ventilation, and air conditioning (HVAC) system. Night ventilation systems automatically ventilate houses using the normal air handler, supply, and return duct system, as...

Project SummaryA “control interlock” to stop air entering a dairy milking vacuum system. When milking cows, a pulsation unit lets atmospheric air into chambers at the milking claw which makes a gripping motion and then milk flows from the cow. When milk stops flowing, existing controls detach the...

Project SummaryOffice of the Future looks across a spectrum of technologies and energy factors including thermal comfort, lighting systems, building envelope, plug loads and overlays economic and human factors analysis on traditional engineering and product improvement efforts. The resulting models...

Project SummaryThe purpose of this Outdoor Lighting Symposium was to bring together researchers and stakeholders to identify and address key issues in efficient outdoor lighting, particularly in the arena of outdated lighting standards. One of the key goals was to begin the process of generating...

Project SummaryThis report summarizes the third phase of an LED street lighting assessment project conducted to study the applicability of LED luminaires in a street lighting application. In Phase II, fifteen 78-watt LED luminaries replaced a like number of 121-watt high-pressure sodium (HPS)...

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...
