Osterfildern Building

With their project in Ostfildern the German architects Sonja and Robert Brixner succeeded in creating the perfect combination of creative aluminium façade design, durability and high energy efficiency.

Transparent insulation systems, low temperature furnace heating surfaces, an optimum amount of glass in the facade and an exterior sunscreen system operated via photocells provide an excellent indoor climate.  Energy is generated by means of two geothermal probes and a heat pump. The photovoltaic elements on the southern part of the roof produce the required energy for the hydraulic systems and the internal pumps.

The material for the northern facade and the rear – ventilated roof construction (with double standing seam) had to be environmentally compatible, durable and weather-resistant.

Pre-painted aluminium in standing seam quality was chosen because it fulfilled all the requirements and excelled the other materials in lightness and processibility. Pre-painted aluminium in standing seam quality is the ideal solution for all kinds of individual and contemporary design in roofing and facade cladding. Due to the great variety of colours the aluminium can be either blended in the constructional surroundings or be used as contrast. The aluminium is coil coated with a PVdF paint system that applies colour in two or four layers. As a result, the  surfaces are of first-rate quality and have high colour permanence.

Another advantage is the material’s high flexibility allowing individual and architecturally challenging scopes for design. Apart from that, the used aluminium can easily compensate movements of the building or temperature changes.
