With the world becoming more and more digitalized, there is a need for the expansion of data centers. In a small country like Singapore, space is a scarce resource and therefore underground space is being explored for the possibility of housing a data center. With the limit space and oxygen in underground, effective ways to suppress fire and remove the smoke are extremely important. Hence, the project aims for find a suitable fire suppression system and smoke control system for the underground data center that fulfills the tenability limits set by SCDF. The simulations are done using Fire Dynamics Simulator (FDS), computational fluid dynamics (CFD) software. Three scenarios were set up in FDS, with scenario 1 being a simulation with fire suppression system but no smoke control system. Scenario 2 and 3 are both with fire suppression system and smoke control systems, however the setup for smoke control system in the two scenarios differs slightly. Scenario 1 and 2 showed significant amount of smoke during the evacuation period and tenability criteria were not met. Scenario 3 showed promising results where the smoke was largely under control during the evacuation period, and smoke was removed quickly after the fire has been suppressed. Lastly, it was determined that the system setup for scenario 3 is recommended as tenability criteria were satisfied during the evacuation period and smoke is removed the quickest after the fire has been suppressed.
