I am working on project whereat a big retail store wants to use automatic sliding doors for their shop entrances.
According to ASHRAE 90.1-2007, 5.4 Mandatory Provisions -> 5.4.3 Air Leakage -> 5.4.3.2 Fenestration and Doors, the air leakage shall not exceed 2.0 L/s*m² for that product. The manufacturer of the doors states that it is impossible to meet this requirment (they say a limit of 5.0 L/s*m² would be possible).
ASHRAE 90.1-2007, p.18: "Air leakage shall not exceed 5.0 L/s'm2 for glazed swinging entrance doors and for revolving doors and 2.0 L/s·m2 for all other products."
The automatic sliding doors will be used in vestibules. As I interpret it, the requirement is still 2 L/s*m², right?
Has anyone used automatic sliding doors that meets the requirement? Or any other suggestions to solve that problem?
Thanks.

Will they be used for the inside or outside of the vestibule? If outside then I agree that the requirement you note applies.
You might want to look at 90.1-2013 as there are more detailed requirements for additional fenestration/door types.
