This is the final report for 2012 phase (Phase II) of the boiler research performed at PG&E’s Applied Technology Services (ATS) in support of ASHRAE Standard 155P. Standard 155P, “Method of Testing for Rating Commercial Space Heating Boiler Systems”, has been under development by ASHRAE for...

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...

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...

In this study, three emerging evaporative cooling technologies were evaluated using the field test results obtained from six test sites. They are: 1) Outdoor Air Supply (OAS) evaporative pre-cooling; 2) condenser air evaporative pre-cooling; and 3) integrated systems implementing both 1 and 2....

This project will leverage the efforts from ET13SCE7060 (Analysis of Next-Generation Home/Building Energy Management Systems) to conduct laboratory and field evaluations of currently available home/building area network systems. This activity will assess the systems’ effectiveness in implementing...

In 2012, the University of California, Davis (UC Davis), Energy Institute initiated a project funded by the Emerging Technologies Program at the Pacific Gas and Electric Company (PG&E) to retrofit existing residential structures through energy efficiency improvements and with ground source...

Project SummaryThe main objective of this project is to evaluate how well the Honda Smart Home achieves the design goals of reaching zero net energy (ZNE) performance while providing a high level of service to occupants.  The project compares modeled energy use estimates to actual energy...

Project SummaryThe goal of this study is to provide recommendations for integrating emerging technologies into energy efficiency incentive programs for existing Small and Medium Business (SMB) Packaged HVAC applications in Pacific Gas and Electric Company (“PG&E”) territory. To achieve the...
