PG&E’s code readiness subprogram collects data on energy efficiency measures and technologies that will support more robust advocacy in future code cycles rulemakings as well as inform voluntary energy efficiency programs. As part of a twelve-month field evaluation of an advanced...

With a target of reducing applied water, and thus resulting in pump energy savings, a new irrigation technique, Deep Root Irrigation (DRI), was tested in comparison to a conventional dual-line surface drip irrigation system (inline drip emitters) in a young almond orchard on the University...

The project objective was to provide independent evaluation of the Nest Labs (Nest) 2017/18 Summer and Winter Seasonal Savings Impacts Reports for the PG&E Emerging Technologies study, with a goal to evaluate the savings potential of Nest Labs Seasonal Savings and Peak Aware...

The study looks at improvements in residential refrigerator components, including connectivity, provides a market and technical analysis for each and the opportunities and risks for the Energy Star Retail Products Platform...

Southern California Edison (SCE) is planning to produce a case study for the third volume of a publication that contains case studies of commercial buildings that were designed and built to achieve zero net energy (ZNE) performance and for which post-occupancy energy performance data have been...

For four years (2015 to 2018) one of the Central Valley Research Homes (CVRH) in Stockton, CA has been used to evaluate radiant ceiling panel systems in a residential application. The radiant ceiling panel systems tested consists of two brands of panels. In addition, four air-to-water heat pumps...

The measure under study is the sealing and conditioning of existing baseline, and vented crawl spaces at single-family residences. Sealed, conditioned crawl spaces have a vapor barrier on the earthen floor, insulation on the crawl space walls, and a pathway for conditioned air to circulate. The...

Southern California Edison (SCE) is teaming up with EPRI and a large production homebuilder to design, build and monitor a new ZNE residential community in Fontana, CA. SCE will act as the project's lead on emerging DSM technologies, battery storage integration, electrical grid optimization and...

Variable refrigerant flow (VRF) systems are well suited for automated demand response (ADR) because of their high efficiency, inherently flexible design, and more sophisticated controls available from the factory, relative to traditional air conditioners. Although VRF has been used successfully for...
