Occupancy Detection Technology in the Building Based on IoT Environment Sensors

The phenomenon of abnormal climate caused by global warming is a serious problem in the world. Most of the countries around the world have signed the Paris Climate Agreement in response to climate change in 2015. Because of Agreement, countries around the world are making every effort to fulfill Paris obligation. Korea government is also trying to reduce the energy consumption. Among the methods to achieve the goal, commercial building is an important field. Because commercial buildings are energy intensive, we should find the way to save energy in this area to meet reduction target. In the case of commercial buildings, the correlation between occupants and energy consumption is very high. Therefore, the purpose of our study is to detect the occupancy of spaces using IoT environment sensors to save energy on buildings. Some spaces waste the energy to meet the thermal comfort level even when there are no people. In this paper, we show the practical results of our occupancy detection technology using IoT environment sensors to find the wasted space on the building.
