Abstract: Wind-driven natural ventilation in two houses of typical one-storey terrace house in Malaysia has been simulated using Computational Fluid Dynamics (CFD) approach. In this present investigation various effects of urban planning (main road aspect ratio and back lane aspect ratio) and building (roof design and porch length) factors on the ventilation performance were systematically investigated. The presence of porches at front façade of both buildings that facing together is significantly modified in-canyon flow of the main road, hence, affects the ventilation performance of the upwind building. In contrast, the ventilation performance of the downwind building is significantly depends on the width of the back lane as the flow enters the building envelope through the back facade.
