Buildings have a large share in the total energy consumption of the world and a considerable amount of this share is wasted for operating the building services in unoccupied spaces. In order to ensure energy efficient and people oriented built environments, it is necessary to detect the existence and location of occupants in buildings. The process of determining the position of occupants in indoors called indoor localization. The aim of this research is to assess the technological applicability of Bluetooth Low Energy (BLE) technology for indoor localization. BLE technology is already embedded in most of the mobile devices and its properties such as ultra-low power consumption, low cost, and low latency in data exchange make it a good alternative to currently available technologies. In order to determine the viability of the proposed framework, multiple field experiments were carried out in an office building at Middle East Technical University. Location fingerprinting method and k-nearest neighbor algorithm were utilized in the experiments. The results show that BLE technology can be used as a reliable solution for indoor localization as it gives better accuracy and precision results when compared to existing approaches in the industry.
