The coupled heat and moisture transfer through porous building envelope has an important impact on the hydrothermal performance of building enclosure,energy consumption and indoor environment,for which experimental study is essential. Two key problems were investigated about the experimental study of coupled heat and moisture transfer in porous building envelope. After a straightforward review of methods for measuring moisture content of porous material,a convenient and inexpensive facility was proposed which can provide an exact result. Afterwards,three experimental study schemes were discussed,which were often adopted by researchers. And then a new scheme was proposed to the transient heat and mois-ture transfer process in porous building envelope,which can be used to validate mathematical models more accurately,and on the basis of which a new full-scale experimental table was set up. This experimental table is a basis for studying the coupled heat and moisture transfer in porous building envelope and validating the mathematical model.
