Fraunhofer – Institute of Solar Energy System (ISE) in Freiburg

Auszeichnung

The architectural design is developed from the urban environment and the requirements of the passive and active solar energy use. In the comb-shaped building there is a three-storey axis in the form of a magistral which allocated the entrance hall, the technical rooms and the 3-wings building with north-oriented labour-wing and south-oriented office-wing. The distance between both wings allows an optimal natural lighting exposure and the use of solar systems. The concept of the façade is an interpretation of solar building taking account into economic determining factors and an adequate representation of the institute. The north facade of the building is designed as a punctuated façade with heat insulation-combination system.

The building with parapet is built in a lightweight construction. Vertical steel girders with sub construction support the ventilated steel panels. The external sunscreen is designed with a light controlling system. A night-cooling-concept with a minimal technical complexity is developed for the offices in the south facade.

The head building with entrance hall, seminar rooms and canteen is extensive glazed with photovoltaic modules which are integrated in the south façade. The south-oriented roof lights are mounted with photovoltaic modules for shading purpose. The façade of technical rooms and workshops is designed with heat insulation-combination system.
