High-Performance Renovation of Iranian Historical Buildings to Substitute Active Lighting Systems with Natural Light (Case Study: Shahi Bank, Tehran)☆

Abstract In this research, building lighting systems and facade glazing system and architectural design of ‘Shahi Bank’ have been evaluated and developed on the basis of the analysis on natural light patterns, which have been derived based on the simulation process by ECOTECT software. 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.
