Our mechanical engneer/energy modeler just contacted me to ask about a discrepancy in our square footages from what we have entered on PIf2 on LEED Online, and what he has input in the energy model, which is about a 5000 sq. ft. difference. He said his area calculation includes floor space taken by walls and chases, not just the occupied space. If our energy modeler/mechanical engineer enters a different value for the gross square footage on EAp2 form, will this be a problem with LEED when they go to review the credit? If so, should we change our gross square footage to match what the mechanical engineer has input in the energy model?

A difference will be flagged by the reviewer if it is greater than 10% or so. Sometimes there is a valid reason for a large difference. If so have the modeler explain in a narrative.
