That means the entire building has to be flipped from heating water to chilled water for the fancoils.
Canadas shoulder season means the nighbts are -2C and the days are 22c, with one day in april hitting 32C and then it snowed a day later. The entire building takes a long time to change over so it isnt usually done until summer.
Classes end in May so any warm spring days they need to open the windows as the cooling isnt available yet.
