Sweco was honoured with second place in the façade renovation design competition for the Leibniz University tower block on Appel Strasse, in Hanover.
This past April a closed competition was held for the 12,000 sqm façade that was in urgent need of renovation. Due to the central location of the University Quarter within an inner-city residential district, as well as the prominent distant views of the tower block, the design requirements were at a particularly high level.
The 17-storey tower block built in the 70s was conceived as a multi-purpose university building, which today houses civil engineering, electrical engineering and information technology. At present, the façade has no significant thermal separation between the interior and exterior, and doesn’t meet the design expectations for a modern campus. In response, the proposed Sweco design called for the removal of the entire existing façade, replacing it with a new building skin that is economical, optimally energy efficient, and easily installed as well as low-maintenance. In this way the building is given a modern look that emphasises the lighthouse character of the tower block.
