I think A wins by default because that close doesn't need a sprinkler?

For the 2010 edition of NFPA 13, isn't the closet exclusion is only for motels and hotels? This looks like it is more of an apartment/longer term living facility. (NFPA 13-2010 Section 8.15.8.2)

A is the better design. The closet doesn't need the sidewall in design B. A also shows an Upright sprinkler in the concealed space above the ceiling. However the sprinkler at the end of the line may be to close to the HVAC Register. Also, the concealed space above the last pendent on the line may need an upright also.

Design A looks like the more efficient design, but is the sidewall serving the main room overspaced for a light hazard sidewall sprinkler?

Marc

Either or neither. There is data missing to accurately design the system. Is this a motel/hotel or a residential occupancy? Can we eliminate that closet sprinkler?

Is the space above the dropped ceiling rated? Is there gyp board to the bottom of the manufactured trusses? Is the upright needed?

Given the assumptions of high rise apartment, B is the better design.
