The size of the system or area that will be illuminated is a very critical issue in the daylighting system. To install the daylighting design in four regions of the building (e.g. roof), it should occupy a small area that has an effective output and adopt the environment according to the required size. The modules are selected according to the range of illumination. A large scale area is more likely to capture light. The distribution of light is also an important issue in the solid-state of lighting. We can use lenses and reflector to distribute uniform light over a certain region at the destination. The use of daylighting can potentially reduce the need for artificial lighting to 20-30% electrical usage and can at least save 10% of energy. The Daylighting design can illuminate most of the space than artificial lighting as per Table 1. (Ullah & Shin, 2013)
