摘要

Many traditional architectural elements are still used in contemporary architecture. One way to give their existence more value is to use to serve design sustainability. Using CFD three-dimensional simulation, this paper investigates the effect of domed roofs on wind-induced natural ventilation performance, considering different building forms and areas, and different wind directions and velocities. Natural ventilation performance has been assessed in terms of airflow rate and internal airflow distribution. Results showed that domes improve ventilation performance in the upstream and central zones of the building, as suction forces acting over them induce more inflow rate through the building and attract some of the outflow to leave through dome openings instead of walls openings.
