The computational formula of dew point temperature was presented according to the physical feature of water vapor such as Michell's saturated water vapour pressure formula. Surface temperature inside wall body was also calculated. Then the comparison between them verified whether wall body has dew. At the same time, the temperatures of every material layer inside wall body were calculated. The partial pressures of saturated water vapour and actual partial pressures of water vapour for every material layer inside wall body were obtained. The two were compared so as to verify whether condensation appears inside wall body.
