For ventilation of the service area, forced suction ventilation is provided. It is constructed with galvanized sheet metal ducts and equipped with a circular canal fan (located outside the room). The air is sucked 50% of the upper and 50% of the lower area of ​​the room (at a height of 0.2m from the floor), providing a multiplicity of air exchange greater than 3 in 1 hour. The exhaust air is thrown to the roof of the building. Compensation of the exhausted air is accomplished through a passive compensation installation. The fan providing the required flow and head has a 1300 m3/h 200Pa. Ventilation grilles are type HN 600/100 with adjustable sections.

 In order to ventilate the Batteries and sanitary units to them, forced suction ventilation is provided. The calculations are based on 90 m3/h for each sanitary room and according to the number of people for the bitumen. It is made of galvanized sheet metal ducts and equipped with a canal fan. The air is suctioned by adjustable conical suction type DVS 125 and grilles type HN 200/100. The exhaust air is discharged into an elevated roof, via a galvanized steel duct attached to the ceiling under the slab. The fan providing the required flow and pressure has a 420 m3/h 200Pa parameter and is a circular duct.

For room air conditioning, air conditioning splitting systems are provided with capacities according to calculated heat losses and cooling loads. The type of indoor units is as follows: For the Column-type Service and Exhibition Hall, for the Office and Waiting Hall - high-wall installation.
