Building where we have less utilization of coerced or artificial energy (energy efficient building) is kenned as green building. Buildings consume a plethora of electrical energy for lighting purport which enforced us to bring something incipient that will directly sanction natural light inside the buildings. By introducing plastic optical fibers in conventional concrete along the cross-sectional area the natural sunlight will directly bring in. In this paper, we will exhaustively study a three story building each floor having four rooms omitting corridors, washrooms, staircases and toilets. We will calculate the energy utilized by the building for lighting purport and compare the same building for economization of energy, where we will utilize plastic optical fibers in minimum at two walls per room of 2mm diameter at 202 divests of plastic optical fibers in one square foot. Additionally we will check for the compressive vigor of the translucent concrete and compare with conventional concrete.
