The project evaluated the performance of the 15W Amerlux Hornet LED fixture as a potential replacement for a variety of low voltage halogen MR16 track lighting applications in a Northern California Safeway grocery store. Given their small form factor and design, which enables them to provide a...

This report is of the first phase of a technical analysis that evaluates the savings potential and market viability of ‘advanced window film’ products that may offer improved characteristics relative to traditional tinted films. The advanced window films, defined for this project as ‘spectrally...

The goal of this project is to establish a laboratory testing program to verify or refute light emitting diode (LED) manufacturer’s product claims regarding life, lumen and color maintenance of directional LED replacement lamps for use in the retail market. Test results will be provided to the...

This is the final report for 2012 phase (Phase II) of the boiler research performed at PG&E’s Applied Technology Services (ATS) in support of ASHRAE Standard 155P. Standard 155P, “Method of Testing for Rating Commercial Space Heating Boiler Systems”, has been under development by ASHRAE for...

Pacific Gas and Electric Company (PG&E) has commissioned this emerging technologies (ET) report to assess both the market for light emitting diode (LED) replacement lamp products and the delivery channels available for utility promotion of these products. As part of this effort, PG&E...

In this study, three emerging evaporative cooling technologies were evaluated using the field test results obtained from six test sites. They are: 1) Outdoor Air Supply (OAS) evaporative pre-cooling; 2) condenser air evaporative pre-cooling; and 3) integrated systems implementing both 1 and 2....

This research project aims to evaluate a Fault Detection and Diagnostics (FDD) product capable of identifying problems associated with the operation of HVAC systems commonly used in commercial buildings including air-handling units, variable air volume (VAV) boxes and chilled water systems.Three...

Computers consume nearly 10 terawatt-hours of electricity in California each year. These and other plug-loads will become an ever larger portion of electricity consumption in the state as California aggressively pursues lighting, heating, ventilation and air conditioning, and building envelope...

This emerging technology report documents the results from the Alpha test of the Honeywell communicating thermostat pilot and Opower behavioral software. In this wave, 17 employees of PG&E had the thermostat installed at their home. The thermostat includes programming that allows it to be...

This emerging technology report documents the results from the initial installations of the Honeywell communicating thermostat and Opower behavioral software trial. The thermostat includes programming that allows it to be remotely programmed through an iPhone app or a PC-based app. It also has the...
