A study of interior light conditions based on natural light is investigated. Ten different iterations are done divided into two seasons, summer and winter. From left, 1) opaque material 2) transparent material 3) translucent material 4) transparent and opaque material 5) transparent, opaque and translucent material. The physical properties used in the simulations are based on the data illustrated at the Vector Foiltec website for an accurate simulation base. Each iteration is containing data of a 3-dimensional point cloud inside the building envelope. To clarify the data, three levels are chosen for illustration revealing little difference between the simulations despite of material change. This can be caused by little difference in light levels due to the dense city environment from the south, east and west, creating many shaded hours on large part of the building facade or due to a well-functioning reflective system, which equalise the intake of light throughout the year. Though the colour chart of the simulations seems identical (to some degree) reading the data reveal diffrentiation in outcome of the different material choses. A combination of opaque, transparent and translucent material properties seem to have effect on the southern side to differ intake of direct sun in specific areas, whereas transparent or translucent properties are more adequate on the northern, eastern and western sides as little direct sunlight occurs within operational hours. Light levels and the distribution of light through the western atrium is very good, where as the eastern can be improved by either directing more light through the envelope via an alteration of the parameters in the local system03 or as a result of widening the atrium space.
