How will revolving doors reduce my heating and air conditioning costs?
As calculated by ASHRAE, air infiltration in the motor-driven revolving door is approximately 32 cf per passage compared to 900 cf per passage in a single swing door, or 1,800 cf per passage through a pair of doors or a sliding door.

Below is a simple chart that outlines cost savings in four different locations around the United States with different climates.
