SPACE PRESSURE

(OP)
I NEED TO KNOW, THE PRESSURE RELATIONS BETWEEN THE CORRIDORS AND THE DEPARTMENT STORES IN A MALL CENTERS REQUIEST IT IS.  SPECIFICALLY THE POSITIVE OR NEGATIVE THE CORRIDORS

RE: SPACE PRESSURE

Air distribution for individual stores should be designed for a particular space occupancy. Some tenant stores maintain a negative pressure relative to the mall for odor control.
Air distribution should maintain a slight positive pressure relative to atmospheric pressure and a neutral pressure relative to most of the individual tenant stores. Exterior entrances should have vestibules with independent heating systems in cold climates and smoke management is required by many building codes, so air distribution should be designed to easily accommodate smoke control requirements.
