A Study on the Improvement of Daylighting Performance for High-rise Residential Building Complex

The purpose of this study is to propose some alternatives for securing a right of light for units within the high-rise residential building complex. Through the literature review, national building codes on the right of light are investigated and both natural daylighting and lighting techniques using equipments are studied. Supposing that a natural daylighting system is a possible alternative to bring daylight into the building, several methods to secure the right of light for buildings in high-rise building complex are proposed through the shadow analysis of different building arrangement, The results of study are as follows; For the shaded areas for the units of lower part of building that is located on the northern part of complex, reflecting mirror can be introduced. Solar radiation area (diffuse light) per unit area of the reflecting mirror is about 20-25m2 and transmission efficiency is about 75%. Regardless of the amount of sunlight, the units of facing north direction is completely excluded from sunlight, but natural daylight can be introduced through the use of reflecting mirror or light duct. For enclosed core spaces without windows to outside, the light pipe equipments from the top floor are effective solutions for daylighting. The enclosed spaces within units can bring daylight with light cable. With the effect of ultraviolet light for interior space, many side effects like sterilization and dehumidification can be obtained.
