What to do with the outdated, unpopular office buildings of the 60s / 70s? ´Demolishing and replacing´ is usually the answer.

BORA takes a different approach and announces a competition for the redesign of the facades at the innovative company’s headquarters. Selection criteria are materials, sustainability, sun protection, passive temperature control and feasibility. The unanimous winner is the project by LORENZATELIERS.

The existing reinforced concrete skeleton buildings are being statically upgraded – mostly during ongoing operation – increased in lightweight construction and equipped with a new thermal shell with movable façade elements in the front. In addition to optimum insulation of the existing reinforced concrete structure and the installation of highly insulating windows, the new building shell is designed as an intelligent energy façade and shows the company’s technical and innovative orientation, in which every component fulfils a technical function. In accordance with BORA’s image, an adaptive overall concept was developed using passive structural measures that ensure comfort and minimize energy consumption. The individually controllable ventilation recovers heat via decentralized, room-related façade elements.

The technical appearance of the façade represents the aesthetics of a future-oriented company. An all-glass roof construction with surrounding terrace offers an inspiring place for seminars and meetings for employees and visitors from all over the world. The spacious roof areas on and around the lower building are designed as green relaxation oases for the employees. As a landmark and corporate identity visible from afar, the main building receives a cantilevered flying roof, the Bora wing.
