Be Cool, Save Fuel


When you enter a building on campus, you are usually on a mission like getting to class, a meeting or an appointment. Rarely do we think about how we do it. Most of us hit the automated door button and keep moving forward. But, every time the automated door is used, heated or cooled indoor air is lost which costs the campus money and causes more fossil fuels to be consumed. It can cost as much as $4,000 per year to condition the air infiltrating a building because of one open door. More than 60 tons of carbon dioxide per year is released into the atmosphere due to one open door.

John Kamman, Campus Facility Services Energy Engineer, recently conducted a study at the Campus Center and Cavanaugh Hall. During an hour and a half observation, which coincided with class schedule traffic patterns, at Cavanaugh Hall the automated door button was pushed 65 times. Two of those pushes were performed by people who were clearly physically unable to open a regular door by themselves. That means that 63 of 65 people (or 97%) using the automated door on the east side of Cavanaugh Hall could have used one of the non-automated doors and saved energy.

In these times of budget cuts and being more "green" CFS is asking that you "Be Cool, Save Fuel" by using non-automated doors when you can.
