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...

Increasing California DR and PLS capabilities requires an understanding of the international, federal, and state organizations that play roles in defining policies, regulations, and mandates for DR and PLS both inside and outside of California. To this end, this scoping study explored the policies,...

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...
