Computational analysis of cross ventilation for spaces with operable transom windows in hot and humid climate.

Author(s) : CHANG C. Y., CHAN Y-C.

Summary

Natural ventilation is an important free cooling strategy for public building in hot or warm climates by providing fresh air and increasing room air flow without using mechanical cooling/ventilation systems when the exterior condition is suitable. While single-sided natural ventilation has been widely studied, the applications of double-sided natural ventilation (cross ventilation) require more attention especially in hot climate and might provide some extra potential for achieving net-zero public buildings. This study aims to analyze cross ventilation in a public space with two transom windows on opposite sides by using 3D steady Computational Fluid Dynamics (CFD) simulations with the SST k-? turbulence model. Three different transom windows types with three different combinations commonly used in Taiwan’s public buildings were analyzed and compared. Parametric study regarding size and position were conducted to provide design recommendations.
