Abstract - Building efficiency must be taken as the
performance improvement of a complex design to deliver occupants with a safe, comfortable and attractive living environment. Higher architecture and engineering designs, quality construction, and intelligent operation of the structures are required for building efficiency. Gradually, operations will take in integration with sophisticated electric utility grids. Lighting signifies 20% of the total energy expenses of residential buildings and 38% of their electrical energy expenses. An efficient lighting-controlling system can significantly reduce the mentioned costs. This paper will discuss the cost-effectiveness of smart lighting control for residential buildings.

1. INTRODUCTION
A decreased use of energy means less to pay for energy bills, reduced load on the grid, and less environmental impact. Lighting is the most common and naturally the most constant form of load. It represents a significant portion of the total electricity consumption of all building types, and it is more prominent in commercial buildings. For instance, according to the US Department of Energy, lighting load represents 11% of energy consumption in residential buildings on average [2]. Other studies show that the average lighting load can be significantly higher in some cases [3]. A European study shows that in the case of average and large buildings, about 40% of the total electricity is used for interior lighting [4]. Residential buildings hold great importance when it comes to energy consumption. Out of the total primary energy requirement of the United States, for example, over one-third is consumed [3]. If office buildings are considered separately, the contribution of lighting energy demand on overall energy consumption can be 20– 25% [5]. So, a reduction in lighting load in residential buildings can have a noteworthy positive impact in decreasing the electricity demand, which in turn helps reduce carbon footprint [6,7], which is a key focus for energy engineers at the current time. Taking the energy impact of lighting systems into viewpoint, various governments and international organizations sponsor specific energy-saving guidelines for lighting systems [8,9]. Later researchers have been continuously booming to do better efficiency in lighting, which means maintaining optimum lighting conditions using as less energy as possible. Research shows significant savings from various types of lighting control schemes [10]. Manual lighting control depends mostly on
Heating, ventilation, and air conditioning are the key areas of energy in buildings—35% of total building energy; lighting—11%; main appliances (water heating, dryers, refrigerators, and freezers)—18% with the enduring 36% in various areas counting electronics. In every case, there are chances both for improving the productivity of lighting devices and the manner they are controlled as a part of integrated building systems. The first and key factor in view of a possible investment in lighting control solutions is cautious monitoring of spending of energy of the building in the necessity of lighting. Since the technology is used in buildings and public spaces, it is very likely that there are many possibilities to reduce energy consumption through some simple strategies such as the utmost use of daylight; optimal distribution of luminaires, and enabling presence detection features. The usage of electrical energy for illuminating industrial plants, streets, or others can be expressively reduced by gaining the finest work system of lighting installation in any given environment. Lighting management is assisted by selecting the appropriate equipment for automatic lighting control. [1] Fig -1 shows U.S. building energy use in 2014. Space conditioning and lighting represent well over half of the total, including energy used in outdoor lighting and cooling in most data centers. [1]
