A building for today and tomorrow The goals: The new administrative building of the Unionhilfswerk was to make an unpretentious but powerful contribution to the urban structure - with a particular focus on sustainability: the building was to blend into its surroundings, offer a high quality of stay, use resources sparingly and age gracefully. The implementation: The new building impresses with its simple elegance and the clear order and rhythm of the openings. The perforated façade is characterized by upright window formats, four-sided circumferential flanges and deep reveals. With its simple and compact volume, the building creates calm in a heterogeneous environment. Features: A The center of the building is formed by an atrium that connects all levels and has openings that are staggered floor by floor. The positioning of the building created two small outdoor spaces: as an extended outdoor zone for the conference area and as a community garden between the nursing home and administration building. The aim of the energy concept is not to exceed a total primary energy requirement per square meter of usable floor space of 100 kWh per year, while ensuring the greatest possible comfort and the best possible room conditions. Thanks to its compact form and monolithic masonry facade, the building is highly energy-efficient.
