Thanks David. As using a capped load factor would not correct any building loss issue, it sounds like square footage needs to be removed from the building service, ie not enclosing the penthouse.
According to BOMA is it required to include all IGA area in the calculation? For instance, we have 20,000sf of enclosed penthouse mechanical, and our client would only like to include 5,000sf as the building service area. This would take less credit than BOMA indicates we are allowed to take and improve the tenant loss factor. Is this an acceptable approach per BOMA?
