Extreme Heat: Continued curtailment

A Stage 4 Chilled Water Curtailment has been implemented on the main campus this afternoon.

Current temperatures are 4 degrees higher than yesterday’s record temps and about 8 degrees hotter than this morning’s forecast. We expect that temperatures will increase over the next few hours.

At Stage 4 curtailment, in addition to previous impacts already noted, temperatures in the research, data processing or communications spaces are allowed to exceed specifications and the water used to cool equipment in those spaces will be affected.

The university is asking for your help in this curtailment. Please shut off all non-essential equipment to reduce load and preserve chilled water for essential needs. Researchers should coordinate with building managers if there are specific, localized mitigations they can undertake while the curtailment is in effect.

Please see Land, Building & Real Estate’s chilled water curtailment guide for further instructions: https://lbre.stanford.edu/sites/lbre-production/files/stanford_chilled_water_curtailment_guide_07-19-public_1.pdf

The duration of the curtailment is unclear at this time. Updates will be posted to emergency.stanford.edu this evening and whenever there is further information.

During this cooling curtailment, managers should encourage precautionary measures and have discussions with employees about alternate work arrangements if needed due to the temperature in their location. If your manager is not available, please contact Human Resources for assistance.
