Daylighting Application Suitable for Architectural Design With Light Tube in Warehouses

Abstract

With the increase in the use of daylight in architecture, providing visual comfort values as well as physical and psychological effects on people and minimizing the lighting energy need of the building have become important in terms of design. Today, with the development of daylight technologies, economic light tubes have become popular in Architecture. Light tubes have become an effective method in Architecture in terms of energy efficiency to illuminate areas of a building that are exposed to limited sunlight. In addition, people prefer to use daylight by nature. Therefore, the use of light tubes continues to increase in buildings with modern architecture. However, due to architectural design and necessities, daylight is used in a limited way in interior areas. While architects determine the position of the light tubes in the building in order for daylight to reach the dark and dim spots of the buildings, knowing the Illuminance level performance of the positioned light tubes has become a necessity for efficient use. In the study conducted to solve this problem, the Daylight Factor Method specified in the European Union EN 17037:2018 Standard was used in the use of light tubes. As stated in the relevant standard, the methods in the daylight factor value ISO 15469:2004 were used. The evaluation of the buildings in terms of daylight performance was calculated in the simulation environment according to the horizontal luminance of the daylight openings. With the designed simulation, the values in the conditions specified in the criteria related to the light tubes are provided. In this way, a light tube that provides energy efficiency is compatible with the circadian rhythm and is compatible with the architecture of this building, and optimum illuminance level values have been determined for the warehouse, which is the subject of the study in the simulation environment.
