Flex Your Power Case Study: San Francisco Civic Center Facility

San Francisco Civic Center (SFCC) engineers collected peak load and average daily load data from paper logs. The data showed that the building used a lot of energy and that usage could be cut while maintaining a safe and comfortable environment. An energy services company (ESCo), Invensys, was hired to make preliminary recommendations for energy conservation opportunities. SFCC engineering staff was responsible for planning and implementing energy conservation projects. The building
manager and chief engineer oversaw the projects. The energy conservation program targeted the building's energy management system and lighting and heating/ cooling
systems, as well as the hours of operation for heating, ventilating and air conditioning (HVAC) and lighting.

The goal of this project was to reduce energy usage at the San Francisco Civic Center.

In June 2000, the San Francisco Civic Center's peak KW (PKW) was 3,200 KW. Between June 2000 and June 2001, the facility implemented conservation improvements amounting to 501 KW reductions in lighting, HVAC and plug-in loads. In addition to those conservation improvements, the peak load reduction (PLR) plan in Stage 2 or 3 identified an opportunity for 88 KW additional curtailments for a total 589-PKW reduction by June 2001.
