| In order to achieve more efficient natural ventilation and better indoor environment in residences, this paper utilizes numerical simulation to explore the optimization of residential architecture design. In case study, the natural ventilation efficiency of a residence in Chongqing is evaluated by quantitatively analyzing the fields of air velocity and PMV from CFD simulations results, which are validated by field measurements. The analysis shows that the natural ventilation is efficient in the living room, but inefficient in some other rooms. In view of this, some feasible alternative configurations without major changes in the building structures have been studied, including different styles of windows and door positions. It is found that the optimized design could improve the indoor environment by reducing the dead zone and increasing thermal comfort zone. Finally, some architectural design suggestions on the doors and windows in natural ventilated residences are put forward. |
