The heat flow meter method and average method have been widely used to measure and analyze the thermal resistance of building exterior walls because of their popularity and convenience. However, low accuracy and long measurement period are obvious limitations of these methods, and many studies have been conducted to address them. These studies reported that the temperature difference between indoor and outdoor environment is the most important factor affecting the accuracy and convergence characteristics of in situ thermal resistance estimation. However, these studies analyzed only a small number of cases with specific temperature differences, so the influence of various temperature differences that can occur in practice were not investigated. This study aimed to analyze the influence of the average temperature difference on the convergence characteristics and accuracy of in situ thermal resistance estimation using the average method. Data measured by the heat flow meter method from October 2022 to May 2023 on the north-facing wall of a full-scale experimental building were used. The findings show that the percentage of convergence satisfaction increases as the temperature difference increases, but each condition differs significantly from the other in ease of satisfaction. For temperature differences above about 12℃, the difference in accuracy due to the fulfillment of convergence conditions was larger than the difference in accuracy due to the increase in temperature difference.
