This Emerging Technologies report documents the results of the Opower/Honeywell Smart Thermostat field assessment. The assessment was launched with two waves of recruitment in mid-to-late 2012. Under a recruit-and-deny research design, a retail intercept recruitment campaign resulted in 695...

Project Summary Field test showed ozone injection system in a jail reduces 88.1% of gas and 18.8% of total water usage, plus unspecified detergent and...

Project Summary Replacing existing and vintage gravity wall furnaces with high-efficiency models can save gas in apartments, average 35.5...

Project Summary Field tests confirmed 1.07 gpm appeared to be the low limit for pre-rinse spray valves used in 6 restaurants in the LA area. The low-flow retrofit achieved an average of 24.9% energy savings, despite an observed increase in average daily use time. The energy and water savings...

Project Summary Retrofit by adding VFD controller to fractional horsepower Hot Water Recirculator in single loop domestic use for apartments and hotels, etc. can save gas 15.6% with a compensating but modest increase in hot water usage of 13.4%; or an average gas savings of about 27 therms per...

HGW Architects is the first commercial ZNE building in San Diego. SDG&E ET collaborated with Savings by Design to make this happen. ET then conducted a comprehensive study to understand modeled vs. actual building performance. The analysis discusses data discrepancies and methods used to...

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,...

The primary goal for this project was to characterize energy efficiency of the Munters EPX 5000 in all modes of operation, in all possible configurations, and across a full range of operating conditions. Laboratory test results were carefully analyzed to consider the technical opportunities and...

The objective of this project was to validate energy savings associated with forced circulation pump driven technology and characterize the energy performance of thermosiphon and forced circulation engine generator block heater technologies under a field testing effort. Analysis of the field...

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...
