The extensive double façades on the west side combine architecture and functionality and feature an excellent combination of wooden supports, steel structures, aluminium profiles and colourful glazing as well as wooden panelling. The façade juts out over the building’s roof. The floors are cross-ventilated thanks to ventilation wings on the rear side of the façade overhang. The wings are turned against the wind, and the onshore wind that frequently blows from the west produces a strong undercurrent that sucks in the cooler air in front of the east façade. The stream of air is effectively supported as soon as the air in the double façade warms up and the temperature rises. The double façade on the winter gardens runs further along into a roof area. The load of the roof construction is supported by a horizontal, 30m long wood-glue binder with specially designed steel supports. From a technical and logistical viewpoint, an area of 36,000sqm of high-grade and highly complex façade and support constructions, spread over three building complexes, was a very appealing project for seele to undertake.
