We are currently working on NC V4 Group buildings. Project is G+2 with total of 100 buildings and distance between the buildings are less than 25 feet. I am finding difficult to locate dedicated smoking area because the adjacent buildings are less than 25 ft and i can't allocate dedicated smoking area on Roof because of Fresh Air Intake. 

Kindly advise how can i implement this credit. Are there are any exceptions or any economic technology that i can implement to achieve this credit.

Thanks you
