When purchasing Green Power for commercial interior fit outs/Floor via the SF methodology, do you typically take the area of the entire space(including ac rooms, freight elevators, stairs,electrical rooms, etc etc) or just the occupied areas( offices, class rooms, hotel rooms etc etc). Also, can you take the gross square footage of the entire building and just divided by the amount of floors to get the average SF and just use that number, or it that not specific enough?

The square foot methodology uses CBECS data and CBECS defines the area as follows:
Floorspace: All the area enclosed by the exterior walls of a building, both finished and unfinished, including indoor parking facilities, basements, hallways, lobbies, stairways, and elevator shafts. For aggregate floorspace statistics, floorspace was summed or aggregated over all buildings in a category (such as all office buildings in the United States).
So I would use that square footage methodology to match the data source.
