Requirements according to ASHRAE mandatory provision 5.4:
Cargo doors and loading dock doors shall be equipped with weather seals to restrict infiltration when vehicles are parked to doorway.
In our project there will be an open loading dock where several (two or more) trucks can dock at the same time and from the platform transport goods to the stores. During unloading the loading dock door (one) will be open.
Can we find compliance with another strategy, e.g. use double doors where one is always closed to prevent infiltration? Another method we considered is to use some kind of air curtains.
