I am working on a three story office building, that is registered as LEED Core & Shell, where the 2nd floor will be built-out for the owner's company, which means we know the occupancy of the 2nd floor with the furniture layout. The problem is that the actual gross square foot per occupant is higher than the default gross square foot per occupant of CS Appendix 1. It is written in the Appendix that projects that know the tenant occupancy must use the actual numbers, as long as the gross square foot per occupant is not greater than that in the default occupancy count table. Should we use the default occupancy for all the project then, or is it easily justifiable that the owner would have bigger offices? I have also read that we can provide examples of built buildings that have the same occupancy to justify the change, but where would one find that? Thanks in advance for your help!
