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...

Project SummaryThe objective of this project is to quantify the savings from the use of solar tubes as day lighting sources in relocatable classrooms. Specifically, the classrooms would be retrofitted after baselining to determine the extent to which the use of solar tubes for primary lighting can...

Project SummaryThe first phase of an evaporative cooler technology evaluation project conducted 2003 tested the performance of advanced evaporative coolers (AECs) that used 8 inch thick rigid media. The results showed that advanced coolers are 68-70% more efficient than conventional coolers....

Project SummaryThis scoping study builds on the multi-agency Integrated Design Charrette for energy efficient data centers that took place February 2-3, 2003 at the Pacific Energy Center. Scoping work will focus on the areas of uninterrupted power supply (UPS), high efficiency cooling strategies,...

Project SummaryThe purpose of this project is to evaluate and compare the performance of two types of advanced evaporative coolers to the traditional evaporative cooler. The results will allow validation of energy savings and other manufacturer performance information. For more information, please...

Project Summary:Demonstrate and assess energy and demand savings impacts of the following technologies and design strategies at three sites in northern and central California: -Variable air volume (VAV) for exhaust hoods, including applicable controls, -Makeup introduced through backwall supply...

Project Summary:The current project uses 100% uplight luminaires installed with dimming ballasts and 5000K lamps. Users have the ability to adjust the lighting levels to match their own preference. Dimmed levels and energy usage are metered for individual users and compared to individual users...

This study aims to characterize the performance of a second Gas Absorption Heat Pump (GAHP) unit to sufficiently populate model inputs in EnergyPlus. Gas Technology Institute (GTI) Energy will serve as a contractor for this study. They will develop a test plan including instrumentation, plumbing,...
