عملکرد بالا نوسازی ساختمان های تاریخی ایران به جای سیستم های روشنایی فعال با نور طبیعی (مطالعه موردی: بانک شاهی، تهران)

During the simulation process, both conditions before and after the design, have been examined and compared with each other. The results from simulations show that absence of appropriate light levels in the middle of the main hall can be solved by locating three light tubes, which could provide an adequate natural light level for this space.
