چکیده مقاله:

Natural ventilation has been widely used in buildings in order to deliver a healthy and comfortable built environment for occupants in buildings. It also reduces the consumption of energy in the built environment and dilutes the concentration of carbon dioxide. Various methods and techniques have been implemented to evaluate and predict indoor air ratio and pattern in buildings. However, few studies have been implemented to justify the most relevant methods for examining ventilation performance at indoor and outdoor spaces. The current study aims to review all available methods to finalize the most reliable methods in order to use in future research. The study uses available data bases and compares the advantages and drawbacks of methods including analytical models, empirical models and CFD models. It was found that the CFD model is the most relevant method due to cost effectiveness and informative technique. Also, it seems as a most relevant approach due to its capability to predict air velocity patterns and ratio in buildings.
