Monitoring - 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 243 – Intercollegiate Athletics Building 275 – Education Building 276 – Social Sciences and Media Studies 277 – Pollock Theater 505 – Events Center 515 – Humanities and Social Sciences Building 517 – Alumni House (Mosher Alumni House) 521 – Environmental Sciences Building (Bren Hall) 525 – Library 531 – Music Classroom Building 535 – North Hall 544 – Noble Hall 551 – Psychology Building 554 – Snidecor Hall 556 – Engineering I (Harold Frank Hall)
If you have questions about a specific building or system, contact Facilities Management: pf-customerservice@ucsb.edu

Construction activities will center around underground utility work beneath the closed portion of the roadway for the East Campus project. Flaggers and signage will be provided during the closure to assist the public navigating this route.
Should you have any questions or concerns regarding these traffic impacts and construction work, please contact DCS Project Manager, Ana Heris at anaheris@ucsb.edu.
