The Effect of the Performance of the Optical Shelf (External) in Creating a Comfortable Environment in Architectural Studios in Latitude 35

Architecture students are in the studios for many hours during the day. Therefore, the use of natural light is important. If these lights exceed a certain limit, they cause disturbance, which is called glare, and one of the ways to solve it is to use a light shelf or a light window. These shelves are implemented in different forms. The purpose of this article is to investigate the effect of the angle on the (external) shelves in the climate of Tehran. The research method of the article is practical and since the response to glare is done into two categories: dynamic and static. Used. In the simulation environment, a cube with dimensions of 8 x 6 is simulated with 30% windows in the south view, and the work surface is proportional to the height of the tables of 1 meter; The sky is considered to be at the solar surface. In this simulation, UDI, ASE, UDA, and DF have been implemented in four modes (without optical shelf; optical shelf with 180 degrees and 30 < X < 60 degrees (external, internal)). After the simulation, contrary to what we expected; It has been observed that the optical shelf performs better than the 180 degree optical shelf in two angled modes. The DF performs better when angled inward, and the UDI when angled outward receives close to 100 lux of natural light in bright mode. The SDA parameter is suitable in two angular modes. ASE, the annual light level in the maximum mode receives more than 60% of natural light, which is desirable.
