An energy-efficient aluminium and glass façade for a new award-winning conference centre in the historic town of Heidenheim in Germany was created using Wicona curtain walling, window and door systems.
This complex development, which also includes a new hotel and an underground car park, is located near to the Hellenstein Castle. It was designed by architects Dasch, Zürn & von Scholley and realised by Oei & Bromberger Architects. The main contractor was Ed. Züblin AG.
An Unrestrained Geometry for the Building
Fundamental to the centre’s design was to reflect the outline of the castle mount, which involved the creation of a hollow cut into the mount. The conference centre extends downhill with an unrestrained geometry, exploiting the topography of the area and creating an unusual and dramatic entrance. Visitors enter the building through the hall’s galleries to make their way through to the foyer. Walls run diagonally to form a series of unusual spaces, giving visitors a sense of harmony.
Delivering a High Level of Natural Light and Outstanding Thermal Performance
The Wicona curtain walling and in particular the diagonal glazing panels allow a high level of natural light into the building and illuminate the foyer on several levels. The extensive floor-to-ceiling glazing provides an interesting contrast to the fully enclosed cube-shaped hall. In addition to the large spans of curtain walling, Wicona windows partially feature coloured outer sections for an eye-catching appearance, with dark zinc cladding panels enclosing the main hall.
The transparent areas of the façade were created using Wicona’s WICTEC 50HI stick curtain walling which has narrow 50mm sight lines both internally and externally, and the HI option delivers enhanced thermal performance, achieving a U value of 1.2 W/m2K . The system is one of the first aluminium façade systems to achieve passive house standards, realising U values of up to 0.74 W/m2K.
Windows Inserted into Curtain Walling Provide a Seamless Finish
Wicona’s highly insulated WICLINE casement windows are fully compatible with the WICTEC curtain walling and were inserted into the façade for a seamless finish. The WICSTYLE door system was used for the entrance areas, fitted into curtain walling and as a standalone door. This product offers the advantage of an identical appearance, and the same design and technology whether it is an open-in or open-out system or an emergency exit door. Wicona also supplied WICSTYLE 77 FP doors to meet the stringent specification for fire protection.
Inside, the conference centre features a series of natural hues – a vibrant green glass wall encloses the cloakroom and contrasts with anthracite metal cladding to the cube-shaped hall. The foyer and galleries are paved with light grey Jura marble with fine walnut parquet flooring for the hall and conference space.
An Award-winning Building
Following its completion, the Congress Centrum Heindenheim has received a prestigious architectural award from the Baden-Württemberg Architectural Association in recognition of its design excellence.
