As condensation is recognized as a major problem and defect in buildings, There is a need for an accurate evaluation method and criteria for determining condensation. However, in Korea, there is no evaluation criteria other than whether surface condensation using TDR occurs in a steady state. Therefore, The study considered methods for evaluating internal condensation in abnormal conditions and compared and analyzed the EN 15026 benchmark results. Comparing the evaluation index of EN 15026 and the calculated values of the researched evaluation method, the overall distribution of the temperature and the moisture content and the shape of the graph were calculated and analyzed very similarly. Later, the researched Matsumoto Mamoru algorithm is applied to reduce condensation in the initial design, and further research on the analysis of various structures will be performed.
