The Gas Technology Institute proposed and executed this 36‐month research program of closely linked projects to help facilitate the overall goal of reducing natural gas consumption for residential water heating in California. Using guidance from the Energy Commission’s Public Interest Energy...

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...

The goal of this study was a quantitative analysis researching the known penetration of energy management systems (EMS) for existing commercial buildings in PG&E territory and a snapshot of the Energy Management and Information Systems (EMIS) technologies currently available. HMG used the...

The project assessed the energy savings potential of a 200 Watt LED High Bay fixture manufactured by BritePointe in replacement of 400 Watt Metal Halide fixtures located within a municipal gymnasium setting owned by the City of San José.  An initial analysis of energy savings of 34% resulted...

Hybrid light emitting diode (LED) and 36-inch linear fluorescent lamp to a replace 48-inch linear fluorescent lamp in stairwell applications. The lamp has a built-in occupancy sensor that switches power from the fluorescent lamp to the LED lamp when the stairwell is...

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 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 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...
