Window Sizing for Daylighting for Non-Airconditioned Buildings in Andhra Pradesh, India

Srikonda R

A window is an opening designed or created in the wall or any surface exposed to external environment to admit daylight, facilitate cross ventilation and contribute to thermal comfort conditions. This paper deals exclusively about drawing adequate daylight to internal spaces from available day light outside. It is analysed and found that the appropriate proportions of sizes, proper location to achieve uniform spread of daylight and penetration levels. The spread of day light intensity related contours have been analysed on horizontal working plane at 0.75 m from the finished floor level in a room size of 6.0 m*4.0 m through a building code method and simulation and it was found that the size and location of windows are appropriate enough to illuminate the daylight with proper spread and distribution in Vijayawada region of Andhra Pradesh in India. It was also assessed that window of the same size can be split in to two windows and placing at side by side walls/vertical planes was more effective in spread/distribution of day light on working plane. The day lighting considerations in this region are essential for saving the energy and sustainability.
