An approach to the simulation of coupled heat and mass flows in buildings

This paper describes the techniques used within the ESPR3 system to represent and solve the heat and mass conservation equations relation to combined building and plant systems. In Particular, it describes the equation-sets used to represent inter-zonal (building) and inter-component (plant) fluid flow and the method used for the integration of the non-linear heat and muss frow equations. By means of a case study, the application in a real design context is demonstrated.
