How can we ensure that we're conserving energy?

With a lively patron load, we deal with a lot of traffic. This means doors open and close often when students go in and out. Also, what about lighting? How can we save money on electricity when we have a duty to maintain a reasonable academic environment?

We've discussed trying to figure out how to us natural light as opposed to having lights on. There are some problems with this as we are a service institution- one that focuses on reading. How can we turn down the lights on our readers? Our particular building has a lot of windows- perhaps shutting the lights off by the windows would make sense.

Or, if that isn't practical, I wonder if there's a way to shut off every other "row" of lights. They're mostly ceiling fluorescent lights. We'll have to play around with some ideas on how to keep our patrons happy as well as conserve energy.
