Optimizing natural light transmission for a reduction in energy consumption in architectural spaces

In architecture, daylight contributes to humans' mental and physical well-being and reduces the consumption of fossil fuels. Accordingly, Iran's rich architecture has valuable achievements and experiences that should be recognized and introduced to the Iranian and international architecture communities. There are many ways to reduce energy consumption in buildings, but electricity accounts for a large part of that consumption. Lighting up spaces with natural light is a significant factor in reducing energy consumption and preventing electricity dissipation. Aside from being expensive, electric lighting systems cause excessive heat and physical injury (eyes). This study is based on library records and documents. Modern lighting systems are used to reduce energy consumption in the interior of a building to allow for optimal transmission of natural light. After discussing the benefits of natural light in buildings, this study outlines how to use natural light in architecture. According to the results, using new methods such as a light tube system and mirror directors is a step toward greater use of solar energy and saving electrical power in residential, administrative, commercial and educational buildings. The investment costs in these systems are quickly returned.
