Modeling cross-ventilation with multi-zone models
In the temperate climate region of Western Europe (UK/Belgium/France, The Netherlands, Germany), simple exhaust ventilation is a widely used ventilation strategy in dwellings. The merits of such systems in terms of ventilation performance have been studied intensively, mainly regarding the impact of sizing of the components (Laverge & Janssens, 2013) and demand controlled operation (Laverge et al. 2011). Cross-ventilaton strategies usually focus on window opening behaviour and exposure of the facades to the wind conditions. Maeyens (2003), however, demonstrated that the internal partitioning of the dwelling has a major impact on the expected ventilation flow rates. In conditions where the trickle ventilators of simple exhaust ventilation systems are sized for low pressure differences such as in the Belgian (2 Pa) or Dutch (1 Pa) ventilation standards, the pressure difference due to wind is often larger than that generated by the exhaust fan. Crossventilation therefore plays a major role in the performance of such systems. Below, the impact of internal partitioning of the dwelling on the share of cross ventilation in the total ventilation flow rate and ventilation heat loss will be discussed.
