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...

This project is phase 2 of 2 that focused on the development and deployment of a residential radiant HVAC system with peak load shifting on the cooling system. The major components of the system include radiant panels, water chiller, water heater, pumps and controls, and the hydronic distribution...

This review investigates the energy savings potential of an adaptive refrigeration controller for walk-in freezers and refrigerators. The technology continuously monitors conditions of a refrigeration unit and controls the system components in real time. Our study monitors the use of specific...

Wireless pneumatic thermostats (WPTs) present a retrofit opportunity that can enable energy-saving control strategies to be implemented in commercial buildings with older pneumatic HVAC controls. The goals of the scaled field placement were to evaluate the implementation of WPT systems at four...

The project assessed the energy savings potential of LED lighting with an advanced lighting control system (ALCS) in a commercial office building. The control strategies were implemented and monitored in the following phases: 1. Existing fluorescent lighting 2. New LED luminaires at full...

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...

Pacific Gas and Electric Company (PG&E) partnered with the California Lighting Technology Center (CLTC) at the University of California, Davis, to assess how education or incentive programs for lighting that uses light-emitting diode (LED) technology might best serve retail business owners...

The growing availability of detailed energy information for California’s utility customers makes possible new programmatic approaches for delivering energy efficiency and demand management services. A 2011 technology assessment that provided a grocery customer with an Energy Information...
