The purpose of this study is to control the occupants" location based radiant floor heating system for improving the inefficient use of energy in the residential building. In this study, the fingerprinting method was used to estimate the location of occupants connected to Wi-Fi through the smartphone. Based on the location of occupants, the energy usage amount and comfort of representative room control method and individual room control method were analyzed. As a result of this study, the location estimation of occupants showed 100% of accuracy. As compared to the existing control method, the corresponding control method showed better comfort and reduced energy consumption by 8.5%.

This study is to propose a method of predicting the number of present occupants using Wi-Fi, a sensor within the building. The accuracy and correlation of the estimated number of occupant by proposing method and schedule for generally used in a building energy simulation were compared with real occupant schedule. The validation of the proposed method has been made. MAC(Media Access Control) address and Wi-Fi was used to predict the number of present occupants, and data were collected and analyzed for 20 days. The energy consumption for air conditioning and the indoor CO₂ concentration were analyzed to examine the influence of the number of present occupant using EnergyPlus. The results showed that the method considering the regression coefficient on the number of occupant accessing Wi-Fi is the most close to the real values and occupants, air-conditioning system energy use and CO₂ concentration.
