Computer simulation on natural ventilation design of a warehouse

A typical warehouse has metal cladding-steel frame structure and overheating can easily occur due to solar radiation and stratified space especially in region with hot and humid climate such as Malaysia, The studied warehouse is located in Johor Bahru and can be regarded as a typical warehouse. Temp...
