You could lobby BC to install AC, but I’m betting it’s unlikely unless you also turn up a benefactor: AC is expensive to install, especially in older buildings, and actually uses more energy than heating does. Most residence halls are empty for most of the hottest months, so installing AC to offset heat for what would amount to a few weeks out of the year… let’s just say BC might have other ways to spend that money. Meanwhile, do what folks did before AC: fans, lots of cool liquids, lightweight loose clothing, draw blinds/curtains during the day, take a cool shower before bed, (dampen a bedsheet if it’s really hot at night), and get relief in AC buildings like the library.
