Computational analysis on the effects of façade modifications on wind-driven natural ventilation performance of a single-cell room

Research output: Contribution to journalArticle

Abstract

Single-sided ventilated (SSV) buildings have been always assumed to be less efficient in natural ventilation performance compared to cross ventilated building, thus when a good ventilation performance is required in a building the single-sided ventilation strategy has always been ignored as an alternative ventilation strategy to cross ventilation. It is known that the cross ventilation strategy can generally perform better than the single sided ventilation. However, this is not necessarily true in all cases, due to various factors such as wind direction and façade treatment. The objective of this study is to investigate wind-driven natural ventilation performances for a single-cell room with various façade treatment options. This study explores various façade treatments, and the performance of each façade treatment is evaluated. This study uses computational analysis to investigate the ventilation performances. This research methodology is used due to its flexibility and post-processing advantage. This study found that façade treatments such as wing-wall and balcony can significantly influences the natural ventilation performance of a single-cell room.
