Abstrakt

In the paper, the authors analyzed the impact of space and time discretization on the simulation results of air flow through the double skin façade and its distribution in the adjacent zone. Temperature and air flow in the different parts of the room were considered, taking into account the influence of changeable solar irradiation and wind speed. The calculations additionally took into account: geometry of the zone and its position in the building; weather conditions; façade orientation relative to the cardinal directions; size and types of ventilation components in the network flow.
