Abstract

Currently, there are ‘condensation prevention design standards for residential buildings’ in Korea that only consider the surface condensation of the structure. However, most cases of condensation defects are due to the interstitial condensation of the structure. In this study, the degree of interstitial condensation phenomenon for internal insulation walls in general residential buildings according to the regional weather conditions was analyzed. To perform the analysis, a simulation evaluation was conducted through an analytical model by extracting the meteorological data factors influencing interstitial condensation, and by collecting local meteorological data in Korea. The results are as follow. 1) As a result of extracting outdoor meteorological data factors for interstitial condensation evaluation, the temperature, relative humidity, total solar radiation, diffuse sky solar radiation, wind speed, wind direction, and precipitation were presented. 2) Simulation evaluation results on the occurrence of interstitial condensation through meteorological data from 9 regions of Korea show that they differ depending on the meteorological characteristics of each region.
