The overarching Demand Response (DR) Appliance project is aimed at three types of residential appliances: refrigerators, dishwashers, and clothes washers. This report focuses on refrigerators manufactured by LG Electronics. Concurrent with this project, the U.S. Environmental Protection...

This project aims to demonstrate use of a broadband/ZigBee gateway capable of meeting the CAISO’s requirements for DR bidding of sub-200-kW commercial and industrial DR loads into ancillary service markets. Engineers will lab test and demonstrate a new architecture that utilizes a smart meter, a...

This project set out to evaluate the effectiveness of an energy management program that combines an EMIS with technical support, in the form of an Energy Coach, to drive energy savings for small and medium business customers in PG&E’s service territory. To do so, we deployed a test...

This report is the second phase of a technical assessment evaluating retrofit technologies for existing SMB Packaged HVAC applications. Phase I of this project, completed in 2012, consisted of a market assessment and selection of technologies for field study. Phase II of this project consisted of...

This project will assess phase change materials (PCMs) in single-wide mobile homes. The test will consist of three test homes: a control (no PCM), PCM in walls, and PCM in the ceiling. Results will inform energy performance potential of...

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...

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...

This report presents a number of new supporting controls technologies that have the potential to enable new energy-saving functionalities in buildings. However, not finding any appropriate existing tools to estimate energy savings, the Consultant developed streamlined methods that can be used to...

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...

This study evaluates the potential for energy management information systems [EMIS] to create or enhance energy savings and the effectiveness of various technologies that enable successful EMIS integration in existing commercial buildings. Appendix: EMIS Product Review...
