Background: Part of our project is a small pavilion building with a plan dimension of 45\' x 55.5\' that will function as a small cafeteria/ banquet space as a supplement to two adjacent high-rise towers. This pavilion space has a total 6 pairs of exterior swing doors and one revolving door. The revolving door will function as the main entry into the pavilion. Visitors will be encouraged to use the main entrance - the revolving door - to enter the pavilion. The revolving door is 6\'-0" in diameter with a permanent walk-off installed within the diameter of the revolving door enclosure. Two of the six pairs of doors will also function as side entrances. Both of these pairs of doors will have 6\'-0" walk-off mats inside the pavilion. The four remaining pairs of doors are intended for natural ventilation only. The arrangement of loose furniture will discourage the use of these doors as entrances. These remaining pairs of doors will not have walk-off mats. Credit Interpretation Request: It is the design team\'s interpretation that the walk-off mats are required only at the main entrance (the revolving door) and at the two side entrances. The arrangement of loose furniture will discourage the use of these remaining four pairs of exterior doors as entrances and therefore walk-off mats are not required at these doors. It is also the design team\'s interpretation that since the revolving door is 6\'-0" in diameter, it would only be necessary to provide the walk-off mat within the diameter of revolving door enclosure. Please confirm that design team\'s interpretation is correct.
The applicants are inquiring as to 1) if the 4 remaining doors qualify as main entrances and are required to provide 6\' walk-off mats in the direction of travel, and 2) Since the revolving door is 6\'-0" in diameter, is it acceptable to only provide the walk-off mat within the diameter of the revolving door enclosure. 1) Past CIR rulings on 7/2/2008 determine that "you should focus on the frequency of use of each building entry point rather than the percentage of building occupants served." If design measures are being taken to distinguish between a high-volume main entrance and create low-volume, secondary entrances for building users, then the low-volume entrances would not require walk-off mats. However, the design solution to create the secondary entrances must also demonstrate that the low-volume design will be permanent. 2) The LEED-CS reference guide states that the permanent entryway systems must be "at least 6 feet long in the primary direction of travel". As the direction of travel will not be a direct path, but will be based on the circumference of the door frame which will result a direction of travel over the entryway that is greater than 6\'-0, the revolving door meets the credit intent.
