LSU Facility Services is enacting “freeze protection protocols” to protect buildings and equipment in anticipation of freezing temperatures forecasted Feb. 20-21.

According to Tammy Millican, the Facility Services executive director of facility and property oversight, the protocols are deployed when temperatures reach below 35 degrees Fahrenheit and involve heightening the water circulation within HVAC coils to prevent freezing.

The resulting increased water circulation may result in buildings being slightly cooler than usual, with building coordinators and researchers being notified of the change ahead of time.

Baton Rouge is expected to see some of its coldest weather since last month, with forecasted temperatures ranging from 25 to 44 and 26 to 49 degrees Fahrenheit on Thursday and Friday, respectively.
