Data source(s) and notes about the submission:
In December 2011, Stanford’s Board of Trustees gave concept approval to the $438 million Stanford Energy System Innovation (SESI) project, which is designed to meet the university’s energy demand though 2050. SESI represents a significant transformation of the university from 100% fossil-fuel-based cogeneration to a more efficient electric heat recovery system, powered by a diverse mix of conventional and renewable electricity sources.
Due to the significant overlap between campus heating and cooling demand, SESI entails an innovative heat recovery design that is 70% more efficient than the existing Central Energy Facility (CEF) operations. In the new system, heat collected from buildings via the chilled-water loop will be captured at the CEF for reuse, reducing the use of conventional chillers to discharge waste heat via cooling towers. Instead, heat recovery chillers will move the heat collected from the chilled water loop to a new hot-water loop scheduled to replace Stanford’s aging steam distribution system.
SESI will result in immense benefits for Stanford University in the decades to come. When completed, SESI will reduce campus greenhouse gas emissions by 50%, save 18% of campus potable water, open up the energy supply platform to future technologies, enable campus to better manage its power portfolio, and yield significantly higher utilities savings though 2050.
