Lab Assessment and Market Analysis of LED replacement products for traditional four-pin...

This project evaluates the lighting performance and energy savings potential of a Lamp-style Retrofit Kit, External Driver (a solution with separate lamp and driver), combined with a Wireless Advanced Lighting Control System (ALCS) to achieve additional energy savings and DR...

The purpose of this project is to verify the energy and water performance of packaged hybrid Roof Top Units (RTU) that combine both evaporative cooling technologies (direct and indirect) with standard vapor compression cooling. The field testing will consist of installing and evaluating the...

The model-based predictive HVAC control enhancement saves energy by generating a predictive model of building operations, then optimizing heating, ventilation, and air conditioning (HVAC) system operations to meet these predicted loads. The specific model-based predictive HVAC control studied in...

This assessment consisted of a side-by-side comparison of two otherwise nearly-identical milk chillers; one with a finned-tube air-cooled condenser with fan cycling on pressure switches, and the other system with a microchannel air-cooled condenser. The project incrementally assessed the...

This project evaluated 10 water systems in the PG&E service territory to determine the amount of energy embedded in water supplies, perform leak audit surveys, review the effectiveness of previous leak remediation efforts (including estimation of the cost and types of leaks fixed), and estimate...

This report presents findings from a field study of an indirect evaporative air conditioner installed as a retrofit at a small restaurant in Rocklin, CA. The study broadens general understanding about application of indirect evaporative cooling systems, documents the level of performance that...

This project will verify the demand and energy savings potential of electrodeless HID over a traditional HID (existing system) at a warehouse (customer site). Light levels will be compared to the existing system. Payback and life cycle cost will also be evaluated for this technology. Technology...

Lab assessment measures the optimal compressor and supply fan speeds in a packaged air-cooled AC unit, for different combinations of cooling load and outside air temperatures. Research provides insight into right-sizing AC units for intended...

This Emerging Technology report describes the data collection and analysis done to evaluate the energy savings potential of an energy management system (EMS) with integrated HVAC and lighting control functionality that is specially designed for small commercial facilities. As part of the project,...
