We are calculating areas using Method B on a building with a distributed core. The BOMA standard makes reference to a multi-occupant floor when determining the base building circulation (BBC). We have a couple of questions regarding BBC on floors that will never have tenants:
1) Does BBC exist in an undergroud parkade?
2) Does BBC exist for a mechanical penthouse floor? Access to portions of the penthouse are via external circulation. If BBC doesn't exist for this floor, would this external circulation then be consider a building service area?
Thank you for your assistance.
