Natural ventilation is alternative and sustainable approach to overcome atmospheric pollutionand global warming and the optimal design of natural ventilation calls for detailed understandingof airflow in the indoor and built urban environment. This paper presented a review of the application of CFD in conducting performance analysis and parametric studies. Augmented withwind-tunnel and full-scale experiment, the direct application of CFD for natural ventilation studies employed whole-domain and domain decomposition techniques. Although, computationallyrelatively inexpensive, the accuracy of domain-decomposition approach can easily be compromised because of the simplifications involved when information is passed from outdoor to indoorenvironment. Therefore, the more accurate whole domain approach can overcome the computational overhead it incurs during application with efficient computing algorithms, grid generationtechniques, and advances in hardware technology. The techniques of CFD are expected to improve and contribute in design and analysis of more complex natural ventilation scenarios.
