Looking for some practical factors for heating an entry vestibule between two sets of doors. The load can easily be calculated with HAP, but I know the calculated value is never enough for these types of applications. The problem is of course that no amount of heat can combat doors that will be constantly opening all day long, so I am looking for some practical correction factors to lump on top of the calculated load.
The good news is that the vestibule will contain a revolving door, but it will also have ADA doors. It is an office building with a lot of traffic in and out. Most should use the revolving door. the outer doors face West in Chicago, which is the prevailing direction from which the wind blows. The objective is to prevent the cold from entering the lobby area just inside the inner doors. Asthetics are a definite concern.
Anyone have experience with this?
