When a building is occupied by a single tenant, is the 2010 Retail Standard applicable for measuring GLA, and are there any differences between measuring GLA for a single occupant or multi-occupant building?

For example, in a single occupant building, are deductions still made for major vertical penetrations, voids, and mechanical and electrical rooms?

As an aside, for a point of clarification - Section 2: Measurement Method in "7 - Measure Gross Leasable Area" says "Make no deductions for columns or for other structural elements or for occupant voids" -- however the "Space Type Chart" indicates that Voids are excluded from GLA.
