In this paper a method for the calculation of simultaneous heat and vapor transfer inside single-layered concrete building components is presented. Specifically, the physical background of this method is outlined and its mathematical core is presented. Furthermore, the computational tool ΥΜΘΥΣ, which is the software implementation of the proposed method, is analytically presented (input/ output data). Finally, the accuracy of the proposed method’s results is verified through their comparison with the results of a widely accepted hygrothermal analysis tool.
