Project Narrative

In addition to the demand for a remarkable indoor climate, this three-story high office building strives for "simplicity" in the sense of robustness: more quality through reduction. The windows in the rammed earth façades have exterior shading. The course of the sun was taken into account in order to provide optimal natural light throughout the whole building. The building is naturally ventilated, with an earth duct preconditioning the outside air, which then enters the office areas via floor outlets. Users can also open the windows. The air is exhausted at the top of the central atrium.
