Building Cooling Alert

A Stage 1 Chilled Water Curtailment, affecting building comfort cooling in many campus academic buildings and offices, is being implemented on the Stanford campus this afternoon (Tuesday, September 5).

Campus buildings are cooled by a chilled water system. Due to the record-high weekend temperatures, along with continued high humidity and high overnight temperatures, the Central Energy Facility (CEF) chilled water storage level is lower than normal. A chilled water curtailment is required to reduce load and restore chilled water storage to normal levels. CEF chilled water production capacity is still less than normal, awaiting the replacement of two chillers in October.

A Stage 1 curtailment means that, in order to preserve sufficient cooling capacity for medical, research, data processing and other facilities, comfort cooling is reduced in many offices and other parts of the campus.

The duration of the curtailment is unclear at this time. Updates will be posted on on Wednesday morning and whenever there is further information.
