For sanitary installations, we worked together with Dornbracht. The greatest challenge was incorporating the smoke dilution system into the existing structure.

Cooling capacity: 600kW

Ventilation: 8 installations, overall 50,000 m³/h (comfort ventilation), 40,000 m³/h garage fume extraction systems, 5 smoke dilution systems for airlock ventilation according to ÖNORM H6029-10

Sanitation: 6000l hot-water boiler, wet rising main according to Austrian fire protection guideline TRVB 128 S.
