Improving energy efficiency in building system using a novel people localization system

Abstract

This paper presents an innovative Bluetooth Low Energy indoor localization system useful to improve energy efficiency in buildings. A tracking system to localize people within a building has been developed using a novel infrastructure system and a custom signal processing method. Knowledge whether people are present or not in every room enables the automatic switching-off of lighting and heating/cooling in empty room increasing the energy efficiency of building system. The implemented method achieves performance comparable to that of a traditional Bluetooth Low Energy indoor location system, nevertheless fewer devices are used. As a result, the cost of installation in existing building decreases.
