Two ventilation systems including a sewer network are to be installed in a new school building with a gymnasium. Both ventilation units are to be installed in the basement (integration via a feed shaft). Ventilation system 1 is a device for approx. 30,000 m3/h (ZUL/ABL) and two thermodynamic treatment stages (heating and cooling). A total of 12 classrooms, some other group rooms and sanitary facilities, as well as the single-seater sports hall are supplied via this ventilation unit over 3 floors (UG to 1st floor). For the exhaust air of the sanitary rooms, individual room fans are planned, which are to be installed in the course of the work. On the two upper floors drywalls with a sliding ceiling connection are planned. Apart from the ventilation centre, the room height is usually a maximum of 3.5 m. Ventilation unit 2 only includes a thermodynamic treatment stage (heating). This unit supplies sanitary and ancillary rooms on one floor (UG). The device should provide approx. 2500 m3/h (ZUL/ABL). In addition, a fan system as battery room ventilation (180 m3/h ABL) for safety lighting, fire alarm and loudspeaker system must be installed in the new building. In addition, a part of the sewer network in an adjacent existing building must be dismantled and, adapted to the new spatial planning, renewed. These are four rooms plus hallways. In both buildings, insulation work is carried out by a separate procurement unit. Fire protection, on the other hand, must be carried out by the Contractor in the ventilation sector.
