In response to the whole building approach to achieve energy efficiency, San Diego Gas & Electric’s Emerging Technologies Program’s (ETP) objective with this assessment was to: * assess the energy efficiency potential of an advanced lighting control system * determine the difficulty...

Project SummaryThe High Ceiling Lighting Options Technology Assessment project studied the applicability of compact fluorescent lamps (CFL) and light emitting diodes (LEDs) in a high ceiling general illumination application. At Hyatt, areas of the grand foyer were selected to replace the base case...

While electric water heaters are less commonplace in PG&E’s residential service territory than natural gas units, where they are used, they can represent a significant portion of a home’s electric demand (up to 5 kW). As a potentially large power user, electric water heaters are likely...

Data centers are among the most energy-intensive facilities. Air management is not only imperative for energy management but also for thermal management. The goal of air management is to supply as little supply air as possible at as high temperature as possible without adversely affecting the...

Project SummaryThe purpose of the study described in this report was to assess three examples of recent HPWHs through laboratory and field testing, and to provide energy performance data to the Integrated Demand-Side Management program. The scope of work included conducting laboratory...

Project Summary This report presents a feasibility study for implementing an energy-pumping optimization algorithm through a Supervisor Control and Data Acquisition (SCADA) System using real-time energy consumption data.  The study was performed as a collaboration between the San Jose...

 Project Summary PG&E partnered with the East Bay Municipal Utility District (EBMUD) to implement a demonstration project involving multiple distribution pumping plants. The goal of the project was to define the impact that water distribution system operators could have on pumping...

Project SummaryThe purpose of this study is to provide information that will assist PG&E in exploring new/alternative energy efficiency programs for Thin Clients, PCs, and Imaging equipment in the commercial segment. This study was designed to explore, obtain, and report the best data and...

Project SummaryIn response to an overwhelming interest in LED general illumination lighting technology among customers in its service area, SDG&E’s objective with this assessment was to: Assess LED lighting technology, validating manufacturer claims regarding energy savings, light levels and...

Project SummaryOccupancy-based guestroom energy management systems sense when a hotel room is occupied and adjust the energy systems — such as HVAC, lighting, and outlets — accordingly to save energy. They may turn systems completely off when a room is unoccupied or, in the case of HVAC, set back...
