1. Natural ventilation modelling for semi-open spaces
The governing equations for wind-driven natural ventilation in dynamic thermal simulation of buildings are presented here. In this article, we restrict ourselves to pressure boundary conditions, so we won't deal with aeraulic modifications linked to temperature gradients.
1.1 Governing equations
In dynamic thermal simulation, the modeling of aeraulic phenomena is based on the Bernoulli approach. This simplified approach represents a reasonable compromise between calculation time and accuracy of flow assessment between zones of a building. Indeed, at the design stage, the level of detail available is often too low for fine modelling of the elements, and the computational cost of digital fluid mechanics makes it impossible to carry out assessments on an annual...
