The purpose of this study is to construct a home energy management system (HEMS) that uses information and communication technologies (ICT) and solar energy more effectively to reduce energy consumption without sacrificing comfort in houses at higher northern latitudes, i.e., in colder climates. The two core technologies of this system are a room environment control system that regulates temperature and illuminance only in the vicinity of the occupants by detecting them and a solar heating system that uses a ventilation heater that warms fresh air via stored solar energy. The aim of the former is to reduce energy consumption by not raising the average room temperature and illuminance. The aim of the latter is to improve the total efficiency of the solar heating system by increasing the efficiency of the input and output of the storage tank.
