Remember though that NFPA 45 recommends you never let it go below 4 ACH even when unoccupied off hours.
And, to add to your comment, I remember saving a lot by simply training our security guards to close any open hood doors that they found during their tours after 7 PM. And record the hood location so the PI could get a gentle - and then not so gentle - reminder until it became a habit.
