The University of the District of Columbia canceled all classes and campus activities today due to heat conditions, spokesperson Alan Etter confirmed this afternoon. The campus closed at noon today, but will reopen tomorrow on its regular schedule, according to a message posted on the school’s web site.

So can the UDC campus really not manage to hold classes once temperatures get up in the upper 80s? Etter explained that UDC’s massive, decades-old boiler system takes nearly a week to switch over from heating to cooling, and this week’s early spring heat wave just didn’t afford the university’s facilities management team enough time to make the adjustment.

“It was state of the art technology in 1975. Now, not so much,” Etter said.

It will probably take a couple more days before the campus’s cooling system is fully operational, according to Etter. But with temperatures expected to drop back down at the end of this week, no further closures are anticipated.
