Extreme heat: comfort cooling curtailment on main campus
Posted: Monday, June 10th, 2019, 5:15 pm PDT

6/11/2019, 10:28 AM, Update:

A Stage 2 Chilled Water Curtailment, affecting the cooling in campus labs, offices and classroom spaces that are not holding final exams, is being implemented on the main Stanford campus today, Tuesday, June 11. Classrooms with final exams scheduled will not be curtailed.

Campus buildings are cooled by a chilled water system. Due to the persistent high temperatures through Monday evening, combined with higher than normal temperatures overnight, the Central Energy Facility (CEF) chilled water must be further curtailed to meet critical loads throughout the day.

A Stage 2 curtailment means that temperatures in labs, offices and classrooms are allowed to exceed campus guidelines for a limited time. A detailed description of Stage 2 curtailment, along with suggested potential actions to minimize impact, can be found in the Land, Buildings & Real Estate’s curtailment guide.

The reduced load will help us make it through this heat wave. The curtailment is expected to last through Tuesday evening. Updates will be posted on emergency.stanford.edu on Tuesday evening and whenever there is further information.

We greatly appreciate your patience. Please take care to stay hydrated and be alert to the needs of your colleagues if the cooling in your location is affected by this curtailment. Environmental Health & Safety has posted an high heat work advisory on its website.

A Stage 1 Chilled Water Curtailment, affecting building comfort cooling in many campus academic buildings and offices, is being implemented on the main Stanford campus this afternoon, Monday, June 10, that is expected to be in place through Tuesday evening.

Campus buildings are cooled by a chilled water system. Due to the unusually high current temperatures, along with expected high overnight temperatures, the Central Energy Facility (CEF) chilled water must be curtailed. A chilled water curtailment is required to reduce load and restore chilled water storage to normal levels.

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. A detailed description of Stage 1 curtailment can be found at https://lbre.stanford.edu/sites/lbre-production/files/stanford_chilled_water_curtailment_guide_10-2017.pdf.

The reduced load will help us make it through this heat wave. The duration of the curtailment is unclear at this time. Updates will be posted on emergency.stanford.edu on Tuesday evening and whenever there is further information.

We greatly appreciate your patience. Please take care to stay hydrated and be alert to the needs of your colleagues if the cooling in your location is affected by this curtailment.
