Comparing condensation theory with hygrothermal models for the mixed climate region of China

Abstract

Calculations of the coupled heat and moisture transfer are necessary for energy-efficient buildings, improving IAQ and durability of building materials. While correct approach requires simultaneous consideration of heat, air and moisture transports, many architects and designers still use the water vapor transport theory without considering other environmental factors. This paper applies either of these two methods to three wall types over summer and winter seasons and compares results highlighting the limitation of the traditional method. © Springer-Verlag Berlin Heidelberg 2014.
