     this study evaluated the effectiveness and performance of smoke management models in a tft-lcd cleanroom. several smoke management models are discussed in a distinct 3-level cleanroom compartment. the tools used included a fire dynamics simulator (fds) and simulex. the design fires were 3 mw and 5.4 mw in ultra fast fire, respectively. in life safety, both a downward smoke exhaust system and upward smoke exhaust system, incorporating a decrease of filter fan unit air supply rate, could be used in a cleanroom, according to the simulation results of performance-based design. for occupant evacuation, the simulex results showed a total evacuation time less than smoke layer descending time, which descended to 1.8 m height from floor to smoke layer in all fds simulations. in view of property protection, insurance companies generally require significantly higher standards of property protection. for 3 mw or more heat release rate, smoke was hardly controlled by any smoke exhaust system in the cleanroom without sprinklers.
