A Review of Daylighting Design and Implementation in Institutional Buildings

It is well known fact that lighting plays a very important role in the performance of any task in a space. Source of light can either be artificial or the sun. Institutional buildings are type of construction in which the occupant uses it the most at the times when natural light is available in plenty. In a learning environment, the lighting plays a very important role. The aim of this research is to study about the lighting requirements of any institutional building by performing a comparative analysis of institutional building. For the purpose of this research, the space that was limited to laboratories and classrooms alone. Building codes specify the average illumination levels required in a space according to the type of function that particular space will host. But case studies reveal that although average illumination levels may be within the recommended range, the actual level of illumination at individual position in the observed space may be too high or too low in the same space, i. e. there is large variation in the distribution of lighting in the space. This distribution of light is affected by several architectural parameters that can be controlled by the architect through the affected design process. The final output of the dissertation consists of design guidelines for the spaces observed, based on the analysis of finding form the live case study and the literature review. The design guidelines deal with the mail architectural parameters that have a direct impact on the indoor light quality.
