Innovations for BAU 2023

After the long, trade fair-free dry spell, architects and tradespeople are once again longing to meet people on site, to hold new products in their hands and not just be presented to them via video conference. Nevertheless, the world has continued to turn and companies have continued to develop their products. The only question is availability and costs. But if the function, quality and availability are right, the costs tend to play a subordinate role.

With the renovation of the Stellinger Höfe in Hamburg and the construction of further buildings, the historical charm of the former railroad site has been preserved. With their combination of masonry and steel construction, the two new buildings blend in perfectly with the industrial flair.

The Mennerich engineering office received support from the heroal project service when planning the numerous heroal systems installed. The service included individual design proposals and the creation of a bill of quantities with the help of tender texts. In order to achieve the desired steel look, all heroal systems installed were coated with a highly weather-resistant powder coating in the color “black grey metallic” with a fine structure. The color used corresponds to the brick façade.

Thanks to the modular design of the heroal C 50 façade system, the profiles can be used with a uniform face width of 50 cm regardless of the construction depth and ensure a harmonious building appearance – even with different thermal insulation and fire protection requirements. The mullion-transom façade system was fitted with insert elements such as the heroal W 72 i block window system and the heroal D 72 project door system, as well as a façade canopy. To protect against direct sunlight, the heroal VS Z sun protection system was used as a partially integrated variant. While the blind box is invisibly integrated into the masonry from the outside, the visible guide rails, end strips and textile screens are color-coordinated with the façade system.

Since the introduction of glass fiber reinforced concrete façade products in 2004, Rieder has continuously expanded its products: the spectrum ranges from large-format thin panels to narrow battens and three-dimensionally shaped elements. The biggest driver for continuous further development is the aspiration to make an active contribution to the energy transition. Rieder achieves this by developing new, durable material combinations and radically reducing waste, among other things.

The model for the durability of the material is the opus caementicium, the cast masonry of the Romans. Thepozzolana added as a binding agent gives ita durability that in some cases exceeds that of modern concrete. This is why Rieder is now gradually replacing the cement for its façade panels with natural and local pozzolans. This means that 50 percent of the cement can be replaced in the new 3.0 concrete matrix. For the products, this means a 30 percent reduction in CO2.

In order to reduce waste in the production of the façade elements, Rieder carried out a waste analysis for over a year. Using over 106,000 parts, the percentage of material suitable for reuse was examined. The “pixel” product, a concrete shingle measuring 147 x 240 millimetres, was ultimately developed from the potential shapes. This means that glass fiber reinforced concrete, which is made from mineral raw materials, can not only be recycled, but also upcycled in the form of small-scale shingles.

The extensive renovation and extension of the Lintharena sports and leisure facility in Näfels/Switzerland took around 20 months. The mosaic series “Loop” by Agrob Buchtal sets the tone on the floors, stairs and walls of the entrance, indoor swimming pool, sanitary zones and changing rooms. Round pixels – set alternately in white, gray and black – provide rhythm in the mosaic and define the different usage zones. In the wellness area, white sprinkles accentuate the otherwise black mosaic walls. This creates an attractive contrast.

The mosaic is ideal for the creative and colorful design of wet areas and showers. 15 high-gloss color variants are available, six of which are matt and slip-resistant. The filigree format also makes it possible to cover rounded components. The glaze fired into the natural clay material is abrasion-resistant and gives the colors a long-lasting radiance. The surface is finished with “Hytect”, making it antibacterial and easy to clean.
