Abstract
A new method for modelling multi-zone air infiltration and ventilation simulation and a simple test case are described. The network approach was used, and the solution was based on a fully implicit formulation of the flow equations. In the present version of the building simulation model (BUS version 2.1), the thermal behaviour of a building is neglected, and constant and uniform air temperatures are assumed. Convergence of the program was tested by test runs. The simulated steady-state mass flow rates and pressures were checked by analytical calculations. The results are found to satisfy both mass balance equations for every node and momentum equations for each flow element when a simple test case is simulated.Keywords
