A simulation approach to the evaluation of coupled heat and mass transfer in building

This paper describes the techniques used within the ESP environment# to simulate coupled heat and mass flows in integrated building and plant systems. In particular, it describes the equation-sets used to represent inter-zonal (building) and inter-component (plant) fluid flow, the method used for the simultaneous solution of these non-linear equations, and the solution coupling of the heat and mass conservation equation-sets. By means of a brief description of a case study, the application in a real building performance evaluation context is demonstrated.
