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...

Cook and Hold ovens are commercial kitchen equipment used to cook food product at low temperatures, followed by a holding period at a specified temperature. Currently, no ASTM standard test procedure exists for cook and hold ovens. A standard has been drafted but needs to be vetted in a laboratory...

Lab testing was conducted to evaluate the efficiency at various loads for PMAC motors at the 3 and 5 HP sizes compared with Premium Efficiency Induction Motor (PEIM) technology. Lab testing found efficiency increases to be between 2% and 24% for the 3 HP motor and 4% to 24% for the 5 HP motor,...

This project aims to evaluate the potential for customers with water pumping equipment to participate in an Ancillary Services DR...

The pool pump system being evaluated is a hybrid AC and solar powered DC system. A DC pool pump is directly fed by PV panels installed on the roof of a building. An automatic digital motor controller changes the torque and speed of the DC motor based on the input power coming from the PV panels....

This system eliminates the central engine room, long piping runs and associated parasitic losses with a traditional ammonia-based system. All components are energy optimized, fully automated, remotely monitored and auto DR ready. This assessment looks at low temperature (-15'F) refrigerated...

This is a revision to the previously submitted report that adjusts findings to provide more relevance for a broader market. (3/30/2015) A field evaluation was conducted of a submersion cooling system installed in an existing data center. Heat was generated by load banks and servers running...

This project will field test recently developed tools and associated workflows to determine the viability and efficacy of rapid building physics based building energy models for use in energy efficiency measure identification and energy use...

The project determines energy and cost savings, particularly during idle periods, as a result of replacing existing, un-lidded char-broilers with lidded char-broilers with thermostatic controls. The project monitors energy consumption, operating conditions, and hours of operation at three sites,...

DC pool pumps, 1/7 HP or 100 Watts, are installed in tandem to the existing AC pool pump (typically 2-3 HP). During the filtration cycle or while moving water through the pool filters, DC pump will be turned on to save energy. Since the pumps remains in this mode most of the time, average usage...
