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...

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...
