Curved façades, but a straightforward energy concept: a new office building in Frankfurt, Germany, clearly shows the potential of sustainable building design, with an architectural style that is not only elegant but also intelligent.
The result is a 90 percent reduced heating demand and perceptibly increased comfort due to high indoor air quality. The building thus meets with the criteria for the Passive House Standard; the corresponding certificate was presented to the building owners this Thursday. Details of the energy efficient solutions for the building services and building envelope will be discussed in April during excursions as part of the International Passive House Conference 2016.
The building, which is being used by the Frankfurt City administration, consists of two parts from an energy point of view: the actual office area on the five upper floors has a heating demand of just 15 kWh/(m2a), while the thermally separate floors below consist of workshops and a car park. The energy demand of this area is very low as well, because Passive House components were consistently used in its construction.
