In addition to the excellent quality of the urban planning, the buildings also impress with their technical design. The external walls have a U-value of 0.16 w/(m2K), which exceeds the German EnEV 2014 energy saving regulation (applicable at the time of construction) by more than 40 percent.
The façade of Wienerberger wet refractory bricks has a potential lifespan of many centuries, with very little maintenance required. “We calculate a minimum useful life of 70 years for our projects. A brick façade is far more economical than any other material,” says Schmidt. The design aimed to create a high-quality, durable and environment friendly buildings. The planners therefore chose a combination of façade bricks and plastered surfaces for the building envelope.
The Polaris wet refractory bricks also enhance the visual appearance of the building, lending it a sense of vitality. It reflects the light differently depending on the position of the sun, so that the colour of the façade changes from light grey to beige and to a warm light brown over the course of the day. In this way, the design and materials work together to create a harmonious overall effect.
