Describe the key innovation and technology aspects of the project

Project Narrative

The new KFW Westarkade building extends and complements the existing ensemble in both materiality and colour. The double-layered wind-pressurised façade has high insulation values, offering natural ventilation independent of the weather as well as efficient solar protection. Radiant floor-slabs and geothermal heating help to further reduce energy consumption. The façade is set back at ground level to create a protective arcade to the street, while the landscape of the Palmengarten is drawn seamlessly into the rear of the site to create a generous open space.
