    There are too many variables with commercial to just use a "rule of thumb". You need to calculate the heat load. Computers, lighting, # of people , interior office, exterior office etc etc etc.

    the "rules of thumb" for residential is 700sq.ft/ton. for commercial it varies depending on the building use typical it runs around 350sq.ft/ton.

    In AZ I consistently see designs that are 250 sq ft per ton. Airflows adjusted for windows and west facing walls. 8 years of engineering college and this is what you get.
