In this scorching weather, we are lucky to have air conditioning in the Library. But people sometimes ask us if we should try to save money by not cooling it so much in the summer. Surprisingly, the answer is no.
This building uses an ice-cooling method called a "chiller." At night, when the energy cost is low, the system freezes water stored under the building. Then in the daytime, the fans circulate air over the ice to chill it, then move it around the building. So it is actually an economical and somewhat "green" system already (because it does not increase demand during peak use hours).
Now, if you would like it less air-conditioned in here because you feel cold, that's something else again! The computer is supposed to keep the temperature moderate and stable, but that doesn't always happen.
