The project in question is the north building of a 2-building, 1 million sf facility. Ongoing purchases and cleaning products are purchased for both the north and south facilities as a whole and not tracked separately. We are thinking about allocating purchases on an area basis. For example if 1,000 reams of paper are purchased and the north building is 700,000 sf then 700 would be attributed to the north building.

Any thoughts on this approach?
