I am looking for a definition for Building effeicnecy factor as it relates to space. Is the definition USF / GrossSF ?
William,
From our perspective, building efficiency factor would be the same as Total Rentable / Total Usable (rentable divided by usable). This will produce a building-wide load factor that describes the percentage of common area across an entire building.
That said, our view is very specific. As a term, I've seen the term "building efficiency" used in different ways.
I am also trying to calculate efficiency and I'm not quite sure how to relate "total rentable" and "total usable" back to the BOMA terms i am familiar with.
Does "total rentable" = total GLA
and does "total usable" = Total CGA?
Hi Gordon,
I'm not sure I understand your question. Usually if you divide rentable by usable, you will get the overall efficiency factor from a leasing point of view. But "efficiency" can mean different things to different people. Relating non-BOMA terms with BOMA terms is not something I can comment on. Total Rentable might not be the same as Gross Leasable Area (GLA) because GLA might have varied meanings since it is not part of any specific standard. Total Usable most likely is not equivalent to CGA (Construction Gross Area). CGA is part of the BOMA Gross Area Standard and it is usually a larger area than Total Usable.
