Turn off lights when not in use—lighting accounts for nearly 50% of the electric bill in most schools. There’s no reason to leave lights on if a room is empty for more than one minute. (And, yes, this applies to the new energy-efficient fluorescent lights.)
Save on energy costs without sacrificing comfort. It’s expensive to heat and cool school buildings, but indoor temperatures must be comfortable so teachers can concentrate on teaching and kids can concentrate on learning. A rule of thumb: Consider setting thermostats at 68 degrees for heating and 78 degrees for cooling. Using fans can make people feel degrees cooler, at much less cost than air conditioning.
Don’t block the airflow around vents. Keep bookcases and other bulky items away from the heating and cooling units so they don’t block and/or absorb the warm (or cool) air that should be coming into the room.
Install programmable thermostats in areas like the cafeteria to minimize operating hours of the heating and cooling systems during low occupancy periods.
Turn down heat in the hallways. And—keep classroom doors closed. Otherwise, the heat runs down the hall and outside—where it is wasted to the outdoors.
Stop leaks!! Look for simple draft beating strategies.
Work with facility staff to install permanent weather stripping, caulking, and insulation.
