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 SummaryRetrofit two existing relocatables with IDEC system to assess ease of installation, equipment performance, impacts on energy usage and demand, and general impressions of classroom users. For more information, please contact the sponsoring...

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. In this study, 36 five-foot fluorescent lights were replaced with 60 four-foot LED light bars at a major grocery...

Project SummaryThe Data Center Energy Efficiency Emerging Technology Demonstration Project focuses on the confinement of chilled air distribution in data center cold aisles. This methodology is based on the observation that current industry practices allow the chilled supply air to mix with...

Some recent studies have performed preliminary investigations into the differences in efficiency and operation of furnaces, including the evaluation of high efficiency prototype blowers. Unfortunately there is no uniform, single method of testing and comparing airflow and efficiency of competing...

Project SummaryThis report presents laboratory test data investigating the operation of an optical demand defrost system in a medium temperature open vertical refrigerated display case. In open vertical display cases, infiltration of warm and moist air into the cabinet is responsible for a...

Project SummaryEvaluated the potential energy savings of a combination of lighting system replacements and a new lighting installation in three different spaces on the LA County Internal Services Division campus. In the welding shop, probe start metal halide aluminum canister fixtures were replaced...

Project SummaryThree tools for diagnosing Air Handler Unit (AHU) problems will be demonstrated and compared to evaluate their attributes in diagnosing problems with air distribution systems. For more information, please contact the sponsoring...

Project SummaryThis project will investigate technical opportunities for and barriers to tankless (a.k.a. instantaneous) natural gas water heater use in residential single family and multi-family buildings, initially for new construction applications and in the future, for retrofit applications....

Project SummaryPG&E has commissioned study which will identify, technically evaluate, and examine market readiness for all existing residential air conditioner charge and air flow verification services. Verification service companies train, certify, list and collect testing data for independent...
