The severe drought underway in California makes water use reduction a high priority. In the case of showering, water use reduction also results in electricity or gas savings which is of direct importance to the Investor Owned Utilities like SDG&E. The technology studied here is mounted in-line with...

This project investigated the technological and business barriers to EE upgrades at a specific multi-tenant light commercial site. While the project focused on this specific site, lessons learned from this project are intended to be a case study with implications for the broader Multi-Tenant Light...

This report documents the results of a pilot field study designed to characterize performance for two indirect evaporative air conditioning products. These systems each utilize indirect evaporative heat exchangers that enable water evaporation to cool a building without adding moisture to the air...

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...
