WINTER BREAK: What’s Down With the Heat?

As with previous winter breaks, campus heating, ventilation and air-conditioning systems will take a vacation as well — but this year only on the official campus holidays, Tuesday-Wednesday, Dec. 24-25 and Dec. 31-Jan. 1 (in addition to the normal weekend setbacks).


On those days, in designated campus buildings, thermostats will be adjusted so that room temperatures drift more widely than normal, getting as cool as perhaps 55 degrees Fahrenheit before the heat kicks in. (So bring an extra sweater if you’re coming in).

These HVAC vacations only apply to offices and classrooms, not to critical spaces such as laboratories and animal spaces. Find out more about holiday energy savings.

Facilities Management personnel will be available all through winter break to address buildings and grounds emergencies. Call the Customer Support Center, 530-752-1655.

Likewise, police and fire services will continue through winter break. For emergencies, call 911. For nonemergencies on the Davis campus, call 530-752-1727 any time.

We’ve also got winter break information on payroll, Human Resources, Occupational Health Services and workers compensation, and Supply Chain Management (including campus mail).

Also during this time, the UC Davis job application system will be offline.
