The dorm required more heating than cooling, but the academic buildings, where students are crammed into classrooms and lecture halls, required more cooling. To Smith, it was counterproductive to spend energy heating one building while simultaneously spending more to cool the others. If heat could be pulled from the academic buildings and pushed to the dorm, it would reduce the energy needs of all three buildings, Smith said.
That is one of those so simple its brilliant but also it is so complicated and brilliant
