OG exemplary drawing
 
1. A structure that is portable, permanent or semi-permanent, wherein the structure comprises:
a housing defining a room therein;
a maintenance room adjacent to the room;
an air flow system that is coupled to the room for providing conditioned air thereto, the air flow system including components located in and exterior to the maintenance room, the air flow system being configured to controllably transition the at least one room to any one of a positive air pressure configuration, a neutral air pressure configuration and a negative air pressure configuration relative to an environment that is external to the housing; an air inlet subsystem configured for drawing inlet air into the room at an inlet rate;
an HVAC system that is located exterior to the maintenance room and is fluidically coupled to the air inlet subsystem for receiving the inlet air, conditioning the inlet air and sending the conditioned air into the room;
an air outlet subsystem configured for receiving outlet air and sending the outlet air out of the room at an outlet rate;
wherein the airflow system further comprises an air pressure control system coupled to the air inlet subsystem and the air outlet subsystem, the air pressure control system having a processor unit that is adapted to control the inlet rate and the outlet rate to enable the air pressure in the room be selectively controlled to be at the positive air pressure configuration, the negative air pressure configuration, or the neutral air pressure configuration, and
wherein the air inlet subsystem and the air outlet subsystem each comprise a HEPA filter unit and a damper unit coupled to the HEPA filter unit, wherein the processor unit is configured to control the inlet rate and the outlet rate of the airflow system by adjusting a valve position of each damper unit.
