Strategies for Enhancing Efficiency of Residential Heating System Based on Real-Time Weather Data

Recent geopolitical instability has led to an unprecedented increase in energy costs, which highlights the need for further enhancement in energy efficiency. Increasing availability of building energy data has been expected to lead to smart heating control systems with enhanced residential heating efficiency. This study investigated the feasibility of passive heating strategies that utilize real-time weather data and ventilation of external air. The results show that passive heating based on ventilation of external air can further increase the heating efficiency under certain conditions. Because the investigated passive heating strategies require only nominal capital investment, they are candidates for implementation in both developed countries and developing countries.
