The multi-layer zone fire smoke movement simulation model (called as MLZ model), a new zone modeling approach, was addressed to predict vertical distributions of the physical properties, such as temperature and chemical species concentration in a building fire. The model still retains the advantage of other zone models in terms of light computational load, so it is expected to be useful for a practical application for fire safety design of a building. In this study, the verification against a fire experiment in a multi-room area is presented. As the result, the predicted temperatures and gas velocity generally show satisfactory agreement. Additionally, a GUI tool which decreases the user’s load for calculation settings and which displays calculation results by color on a two-dimensional plane was introduced.
