The internal layout is very much responsible for the increase in the penetration of useful daylight in the habitable spaces. These lighting units are responsible in cumulating the lighting load of a building. This paper deals with the comparative study including two cases of different apartments in the same city and climate, oriented in the same direction, elaborating the factors over which variation in the lighting units depends and the comparison with the standards. The aim of the study is to elucidate the parameters on which the values of Daylighting depend upon in a composite climate for a residential unit. The readings were recorded with the aid of a lux meter at the time between 3pm to 4pm on a summer day.

Internal layout, Daylight, Openings, Window to Wall ratio, Energy Reduction.
