Less traffic is not less building
Foot traffic drives soil in circulation areas, so a quiet building does need less attention in its lobby and corridors. What does not change is the floor area, the glazing, the external surfaces or the amenities that still serve whoever remains. Nor does dust stop settling, and in an empty building it settles undisturbed until somebody notices the whole place looks neglected. A quiet building can look worse than a busy one within a couple of months.
There is also a leasing consideration that committees sometimes miss. A building with vacant lots is being inspected by prospective tenants and their agents, and the common areas are the first thing they see. Reducing presentation at exactly the moment the scheme most needs to attract occupiers is a false economy, and it is worth saying so before the budget is cut. Committees under budget pressure rarely think of the leasing consequence until somebody raises it.
