An onset to whole building hygrothermal modelling under wind-driven rain loads

This paper gives an onset to whole building hygrothermal modelling of the interaction between interior and exterior climates via building enclosures, which even takes into account wind-driven rain (WDR). First, the temporal and spatial distribution of WDR on the facades of a single leaf brick wall building is numerically determined. Then the hygrothermal behaviour of the walls and the room zone is numerically analysed. The results show that WDR loads can have significant impacts on the indoor climate, energy consumption and mould growth risk.
