To better understand the potential for energy savings through the implementation of bi-level lighting controls in exterior parking and pedestrian spaces, motion detection and data acquisition technologies were installed in selected areas at a total of eight sites in SCE, BPA, and PG&E...

This report presents the results of detailed monitoring of the Cottle Zero Net Energy (ZNE) Home over 12 months from April 1st, 2013 through March 31st, 2014. The home has been occupied during the monitoring period by a family of five who moved in February 2013. Analysis includes evaluation of ZNE...

The Honda Smart Home is a fully functional zero net energy (ZNE) home located in Davis, California, containing many advanced design elements. Pacific Gas and Electric Company (PG&E) partnered with Honda to monitor the performance and grid integration of the Honda Smart Home. PG&E also...

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...

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...

In past funding cycles, SCE funded the development of two studies to introduce OCSTs—formerly referred to as programmable communicating thermostats (PCTs)—into California’s Building Code, Title 24. In 2012, OCSTs were incorporated as alternatives in residential buildings and requirements for...
