Abstract: Green buildings, also known as ecological buildings or sustainable buildings, are said to be environmentally symbiotic in the Asian region. Some results of research literatures showed that there were many functions and products of green buildings that singly or together may have an impact on fire safety unless there are some appropriate design approaches to mitigate those effects. Natural Ventilation effect is also included in two indicators of green building certification, energy saving and indoor environment quality, in Taiwan. However, The inappropriate ventilation strategy in emergency situation will produce some fatal impacts on fire safety of buildings, such as causing stack effect. In this study, Fire Dynamics Simulator (FDS) software was used to assess the impact of the natural ventilation on fire safety of green buildings. The results indicated that smoke accumulation phenomenon is significant since the stack effect of the natural ventilation. In the existing natural ventilation model, if the upper natural smoke vent is incorporated, the evacuation time can be increased.
