If you have a device, a technology, whether you need to use it at the particular time, you will use it. My church was sited, surrounded by trees, a very cooling affect and large floor to ceiling operable windows, open to the woods. The architect had designed the church so it wouldn't need A/C. but decades later, it installed AC. and used it every summer day whether it needed it or not. The noise. Cold and no bird song.
