Audi Centre in Berlin with Uponor
|The integrated used car centre has an efficient Uponor industrial radiant heating system plus concrete core activation with Uponor TAB System in two floor slabs for heating and cooling. The Uponor temperature control system allows for savings of up to 50 % compared to conventional air/air climate control systems.
The construction time was considerably reduced by using air-handling ceilings, manufactured by Elbe Spannbetonwerk, that were pre-fitted at the factory with Uponor modules.
With an extensive glass area, the used car centre covers about 1,600 m² of floor space. The planning specifications called for an economical design with low costs for temperature control. An additional requirement was an eye-pleasing interior. The building’s temperature control system uses energy-efficient sources for heating and cooling.
Elbe Spannbetonwerk supplied a total of 133 prestressed concrete ceiling elements. Prefabricated Uponor modules were integrated into the hollow concrete elements, each 35 cm thick, 120 cm wide, and 12 m long.
The thermally active ceiling on the ground floor of the centre has a heating capacity of approximately 37 W/m² downward and approximately 30 W/m² upward. This is enough to maintain a setpoint temperature of 15 °C. To meet the high demand — especially in the separate offices — additional split air-conditioning units and flat convectors were installed.
