APPLICATION OF DELIGHTING TO OPTIMIZE WINDOW-TO-WALL RATIO (WWR) IN BUILDINGS IN INDIAN CLIMATIC CONDITIONS

This research focuses on the energy performance of buildings with glass windows to allow daylight in three different locations in India. The utilization of glass in modern commercial buildings is rapidly increasing for aesthetic views and daylighting through the glazing. Much research has been conducted on WWR and daylight integration into the building through window glazing. In this study, the window area is distributed to different cardinal directions and the result is compared with the reference building in the study location. Focus has been given to optimizing WWR for different window combinations. Energy consumption in eleven different window combinations and five different WWRs were studied. The result shows the reduction of total energy consumption of buildings with different window combinations as a result of the integration of daylight. Window combinations for higher WWR and the optimum value of WWR in all window combinations are determined.
