Purpose of Simulation :
The investor suspects that louver and roofmonitor size do not guarantee the required ventilation, so they want to do simulation to check indoor ventilation and temperature, if unsatisfactory, offer an optimal solution for ventilation fan but the roof monitors are fixed.
Result :
Indeed, the incorrectly calculated design led to unsatisfactory ventilation. and SAO came up with the optimal solution after many simulation runs, giving the optimal detail parameters and positions of the fans to be installed.
