GTI used a creative way to assess the energy benefits of combi service for single family homes.  The Virtual Test Home (VTH) consists of multiple test rigs and associated algorithms that simulate real world conditions in a controlled, repeatable laboratory environment.  The VTH can be...

The purpose of this project was to conduct laboratory testing on the Indirect/Direct Evaporative Cooler (IDEC) to characterize its performance across typical cooling season weather conditions in climate zones 7 and 10.  The IDEC provides cooling very efficiently using only two sets of fans and...

This project evaluates market-ready connected plug load devices for opportunities in plug load programs. Unlike previous approaches that focus only on the programmatic or technology side, the approach used in this study evaluates the intersectionality between technical capability and program...

Energy storage technologies – and battery energy storage systems (BESS) in particular – have become increasingly popular across global markets over the last five years. BESS technology is now commonly hailed as a panacea solution to help address numerous problems with legacy electric...

This project created algorithms predicting the performance of drain water heat recovery devices as a function of their installed angle. The algorithms use the same process as previous Pacific Gas and Electric (PG&E) drain water heat recovery projects1. Four representative DWHR devices, two...
