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...

The goal of this project is to provide additional insight into the GAHP Tool development based on the following: -Overall daily and annual emissions savings estimates with the option to see a California-specific summary to understand the greenhouse gas (GHG) emissions impact. -A laboratory results...

Spas or hot tubs are normally used year-round, unlike heated pools. Spas typically maintain water temperatures between100-104 F which require fast heating for better customer experience. Spa heating and pool-spa configurations generally involve how the water is heated and circulated between pool...

This is an agile project idea to compare DHW sizing tools to actual site data for (9) multifamily sites. A comparison of data for (6) sites was done in ET23SWG0012 GAHP Sizing, Screening and Design. An additional (9) sites would further refine this analysis to make observations which would be...

The goal of Phase 1 of this project is to develop a tool that provides integration guidelines for emerging gas-fired commercial heat pump water heaters (CHPWH) and baseline equipment (standard & high-efficiency, tankless & storage-type) to ensure: - Ideal system configuration and component sizing,...
