A new numerical calculation method is presented to predict smoke movement among rooms in building fires using volume conservation and energy conservation instead of the previous mass conservation to modify pressure. Furthermore, in this study network modeling was handled with zone modeling method. Then a new program FZN Ver. 3.0 (field, zone, and network modeling) has been developed. In this paper the relevant formula derivation is given. In addition two calculation examples are presented to test the simulation method and program. It is shown that the program could be used to calculate the smoke movement from ignition to any time, and it runs well to predict the smoke movement in building fires.
