Abstract: Increasing population places increasing demands on energy supply, which leads to heavy power deficiency. We can supply only a limited amount of energy to the consumers because we have only limited conventional sources of energy and non-conventional energy sources are mostly still under research and have not been deployed on a large scale. Not only there is limited amount of energy to be supplied to the consumers but heavy demand of energy supply also leads to environment degradation. This creates a need to use the limited energy efficiently. This has given rise to new trend towards reducing the energy consumption: Green Buildings. About 40% of the energy consumption in the world is consumed by buildings [1]. Energy consumed by lighting systems accounts for about 15% of total energy consumption of buildings [1]. Thus we need to use energy efficient lighting devices for illuminating buildings. Thus in this study we to tend to develop optimized energy efficient system, which will use LED lights to illuminate buildings. The illumination intensity of the LED lights will be decided by the FPGA, which is interfaced to the LED driver. Based on combined values of light intensity of the room and occupancy of the room using different sensors, the light output of the LED will be controlled 2016-01-01T00:00:00Z
