Abstract: Daylight offers visual comfort and a healthy environment inside buildings. However, factors like changing sky luminance patterns, occupant behaviour influenced by age and eyesight, daily activity schedule, building location and orientation, building plan, interior design and other socioeconomic factors influence the requirement of artificial illumination during daytime. Therefore to understand the causes in greater detail, a primary survey of 707 households belonging to different housing typologies like bungalows, duplexes, twin houses, row houses and apartments of the linear and angular forms was carried out in the study site. To calculate the hours of low natural illumination within a room, LOWLUX, a MATLAB based code has been developed.
