Bob, It looks like you want to use the room design method. You only need to calc all sprk's in room calc as long as the walls enclosing the room have a fire resistance rating equal to or greater than the corresponding water supply duration requirement for the particular hazard.
If you don't use the room design method, then 1500 sq.ft. Unless you apply a reduction. Sean W. Conlin Demand Sprinkler Design Inc.
