Hi, we have a square atrium in the middle of the building. The floor of the atrium is 30 meters below the level of the roof of the building but it should be classified as a roof construction because there are two more floors under this level. There is almost no direct sunlight on the floor of the atrium due to the shape of the building. Is it possible to classify the all-year shaded area of this structure as compliant in terms of SSc5?
