A Numerical Study About Hygrothermal Performance of Traditional Timber Framed Infilled Exterior Wall

The paper goals to investigate hygrothermal behaviors of traditional timber framed infilled exterior walls in Türkiye by using numerical method. DELPHIN, which is a distinguished hygrothermal simulation tool, was applied. 150 cm × 150 cm wall samples were modelled as timber framed with three different infill materials: stone, adobe and brick. Weather data of three cities; Rize, Karabük, and Eskişehir, where these examples are mostly housed, were used to analyzed hygrothermal behaviors of the wall samples over 2 years in order to simulate real conditions. Temperature and relative humidity values of indoor environment were set as three different conditions. The findings of simulation were obtained as daily data. The analysis of data is based on temperature, relative humidity, and U-value evaluation. The results signify that wall samples may have humidity-based problems depending on various climatic conditions, construction details, intersection of different materials. Additionally, U Value of the wall samples are not responded to the desired values. To conclude, intersection points of materials, layers, and their relations should be deeply examined to develop the hygrothermal performance of the selected walls in the progress of conservation/restoration/renovation projects.
