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....

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 study evaluates the performance of a test installation of Light Emitting Plasma (LEP) lighting and a wireless lighting control system, as compared to incumbent High Pressure Sodium (HPS) lighting, in a high mast application at a study site in northern California. The study evaluates energy...

The residential water heating market in the U.S. is dominated by storage water heaters with 96 percent share and roughly equal sales for electric resistance and natural gas heat sources. Over the last half decade, two water heating technologies have entered the market place bringing significant...

The goal of this project was to develop a list of best-in-class for both PAR30 and PAR38 LED reflector lamps, that not only save energy, but also are likely to meet or exceed residential consumer expectations in their overall performance. In the case of lighting, this means excelling in visual...

During the summer of 2012, the Emerging Technologies program at PG&E collaborated with PG&E’s training center in San Francisco, the Pacific Energy Center (PEC), to update existing lighting installations– replacing what are now generally considered to be standard fixtures in terms of technology and...

In the summer of 2012, the Emerging Technologies program at PG&E collaborated with PG&E’s training center in Stockton, California, the Energy Training Center (ETC), to update existing lighting installations in three rooms and one hallway – replacing what are now generally considered to be standard...

This Xenon lighting evaluation project is divided into two phases. The first phase, documented in this interim report, consists of product evaluation and comparison against traditional exterior source technologies using published manufacturer’s data. The second phase of this project, beginning in...

The California Energy Efficiency Strategic Plan has set a long-term goal that all new residential construction in California be ZNE by 2020. One of Pacific Gas and Electric’s (PG&E) strategies in support of this goal is to inform the local building industry of ZNE benefits, concepts, and...

Ice machines are installed throughout the foodservice and hospitality industry, from bars, delis and restaurants, to hotels, casinos, and other institutional kitchens. Nearly every foodservice operation has at least one ice machine. They also are found in other commercial building types such as...
