NC-2009 EAp2:Minimum Energy Performance

Vestibules

I'm working on a big building, mostly office but not exclusively, in Stockholm, Sweden. I'm currently working on a restaurant on the ground floor with an entrance from outside. I'ts larger then 3000 square feet but it's not the buildings main entrance. The reason I'm not sure if this entrance needs a vestibule is exception b "Doors not intended to be used as a building entrance" and I found: "Interpretation: A door that is not a main public entrance to the building is not required to have a vestibule. A controlled access door that opens to a patio which does not have egress from the building’s exterior would not be considered a building entrance door and therefore would not require a vestibule". This question has probably been discussed earlier but I can't find it and hope someone can help me. Do I need a vestibule on my entrance door for the restaurant? Thanks

An entrance to a restaurant sounds like a public entry to me. The provision you found is really for side doors that are mostly used as exits or an entrance for a small number of building occupants. The purpose is to address doors that are frequently opened. I would think that the entrance to a restaurant would qualify.
