In terms of visual comfort, efficient day lighting in residential buildings offers several physiological and psychological benefits. One of the most important design factors in contemporary architecture is day lighting. Setting backs and window apertures are essential for letting natural light into buildings. However, a lot of interior spaces frequently experience inadequate day lighting because to poor setbacks and window sizes. This article is an academic effort to evaluate the effect of building setbacks on window sizes to obtain pleasing day illumination in the given environment. For this, day illumination in two independently oriented residential buildings in Vijayawada, India, with variable setbacks, was investigated. Using a Lux Meter, the day lighting contours were calculated throughout the day in each of the buildings’ functional spaces/rooms. Additionally, the interior natural lighting levels in various building rooms were compared to the required standard illumination levels as recommended by the local building regulations and The National Building Code of India, 2005. It was found that some interior building spaces lacked adequate day lighting. Design recommendations for window sizes were made in relation to each building setback based on the day lighting research.
