Arup has performed several retro-commissioning projects for the University of California, San Francisco (UCSF). Building off of our successful work reducing their energy costs at the Mount Zion Research Center, we were brought in to do a campus-wide energy study for their Parnassus Campus. In an effort to help UCSF claim utility based incentive funding, the availability window for which was coming to a rapid close, Arup provided a quick explorative energy audit of the UCSF campus over a six week period.
In total, Arup audited over three million square feet of their laboratory, classroom, and office building spaces and developed a list of the most practical energy opportunities that will provide a payback of 7.5 years or less. To expedite the energy audit, Arup utilised two audit teams; one team concentrating on lighting opportunities, and the other concentrating on HVAC system opportunities. The final report identified 18 Energy Conservation Measures that will save 6,215,211kWh of electricity, 344,303 therms of natural gas, and over $940,000 per year in utility costs.
Compared to previous fiscal year energy consumption levels, these savings represent a 10.2% reduction in electrical use and a 6.9% reduction to annual natural gas use. This work by Arup predominantly led to over $1.9 million in utility incentive rebates for the UCSF campus.
