Sacred Heart Schools completed construction of its Stevens Library for lower and middle school students in August 2012. The library is a 6,300 ft2 all-electric building. It was designed and constructed to achieve Zero Net Energy (ZNE) performance--based on total site energy), to meet the Living...

The objective of this project was to develop a functionality testing procedure for residential smart thermostat devices, in support of an energy efficiency and demand response residential smart thermostat rebate program, in the planning stages at the time of this writing. This testing procedure...

Sweetwater Spectrum, a planned community of four single-story residences and a community center located in Sonoma, CA, is designed to serve adults with autism spectrum disorders. The project was initiated as one of several zero net energy demonstrations and provided the opportunity to evaluate...

This report is the second phase of a technical assessment evaluating retrofit technologies for existing SMB Packaged HVAC applications. Phase I of this project, completed in 2012, consisted of a market assessment and selection of technologies for field study. Phase II of this project consisted of...

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,...

Collects energy savings, incremental costs, feasibility, conflict with other building practices for one of the measures under consideration for the 2016 T-24 standards: R-25 walls. Key problems solved: example moderate cost methods of achieving objectives, identifying and avoiding unintended...

A field evaluation was conducted to determine energy and cost savings in a restaurant’s refrigeration load as a result of replacing low-efficiency prep tables with high-efficiency prep tables.  The project monitors baseline energy consumption in eight locations, and replaces...

The objective of this project was to monitor the in-situ performance of a VRF-HR (heat recovery) system and provide performance characterization based on the data recorded.  The site is a 4-floor PG&E office building in Auburn, California which is in California Climate Zone 11.  The...

The focus of this case study of non-intrusive load monitoring (NILM) algorithms by four vendors at 11 non-randomly selected homes in the SDG&E region was to evaluate the rough accuracy of each algorithm in an effort to better understand the state of that industry. Whole building electrical...

As a steward of the environment, the California Energy Commission (CEC) desires to reduce not only electricity consumption but also electricity demand (California Energy Commission, 2013). When peak demand gets too high, the existing primary utility infrastructure is not large enough and in the...
