Facilities Management is issuing this notice to inform the campus community in buildings served by the central chilled water system about how cooling responds during periods of extreme heat and peak demand.
The campus chilled water loop has a finite cooling capacity. When demand on the loop exceeds that capacity - typically during hot weather or periods of heavy campus-wide use - Facilities Management curtails comfort cooling to buildings in order to keep critical systems supporting research operational.
When this happens, affected buildings may experience warmer indoor temperatures than usual. This is expected and temporary. Comfort cooling is restored to normal levels as soon as demand on the loop drops back within capacity. The affected buildings for this curtailment event are as follows:
221 – Student Resource Building (SRB) 223 – Theater & Dance West 243 – Intercollegiate Athletics Building (ICA) 275 – Education 276 – Social Sciences and Media Studies (SSMS) 277 – Pollock Theater 505 – Events Center 515 – Humanities and Social Sciences Building (HSSB) 517 – Mosher Alumni House 521 – Bren Hall 525 – UCSB Library 531 – Music 535 – North Hall 544 – Noble Hall 551 – Psychology 554 – Theater & Dance East 556 – Harold Frank Hall
