San Diego Gas & Electric (SDG&E) retained Daryl DeJean of Emerging Technologies Associates (ETA) as Project Manager to manage an innovative evaluation, measurement and verification (EM&V) of three hotel guest rooms HVAC direct digital control systems at four hotels in San Diego County. ETA worked side by side with California Lighting Technology Center (CLTC) in collecting the energy data and ensuring the integrity of the systems  during the test period.

The High Efficiency Office Low Ambient/Task Lighting project was designed to verify the design concept, and technology functionality. The main objective of the assessment was to determine the level of reduction energy consumption achievable via a low ambient, high task lighting strategy using standard off-the-shelf lighting technologies in the commercial office market end-use.

The project was designed to verify the functionality as well as the lighting levels currently achievable by utilizing an integrated lighting control system. The main objective of the assessment was to determine the level of reduction energy consumption achievable via integrated lighting controls in the commercial office market end-use.

The project was designed to verify the brightness and quality of light currently achievable with replacing traditional linear fluorescent tube lighting in freezer case and refrigerated case applications with new LED linear lighting systems.

ICE II  Cold Storage is a LEED certified cold storage facility located in Otay Mesa, CA. Emerging Technologies was brought in by San Diego Gas & Electric to assess the use of LED's in a high bay warehouse application during the construction of the warehouse. The developer, Hamann Construction were looking for a state of the art high performance lighting system to match the cutting edge technologies utilized in the refrigeration, HVAC and building envelope of the building. 

In the retail jewelry sector, lighting is used to draw shoppers into the store and enhance their buying experience by highlighting products and creating positive visual impressions. This LED retail jewelry display assessment project was designed and conducted by Emerging Technologies Associates (ETA) on behalf of SDG&E to study the applicability of LED Direct Lamp Replacement (DLR) in both ambient and focal-point lighting in the retail jewelry sector. 

The project was designed to verify functionality as well as the brightness and quality of light currently achievable with replacing traditional core and coil HID ballast technology with new electronic HID ballast capable of dimming and Demand Response in instituional end-use.

The project was designed to verify functionality as well as the brightness and quality of light currently achievable with replacing traditional core and coil HID ballast technology with new electronic HID ballast capable of dimming and Demand Response in the supermarket and warehouse retailer end-use.

The project was designed to verify the functionality as well as the lighting levels currently achievable by utilizing an advanced skylight system. The main objective of the assessment was to determine the level of reduction energy consumption achievable through the use of passive skylights.

This consolidated report summarizes the installation and assessment of electronic HID at three sites: a large manufacturing facility, a regional supermarket chain and a community college all located in Northern California. Relying primarily on field testing, the project team conducted photometric and power measurements, as well as customer satisfaction surveys and economic payback calculations. 

This project examines the energy efficiency potential and viability of lighting emitting diode (LED) lighting at an underground parking garage at a major hotel in San Francisco. Light-emitting diode (LED) lights are emerging as a viable alternative for outdoor locations such as parking lots, parking garages, and streets, which typically use wallpaks and bollards lit with high wattage, high intensity discharge (HID) or fluorescent lights. In addition to increased energy efficiency, LEDs offer longer bulb life, reliability, and cool operating temperatures.
