Incheon International Airport(IIA) Terminal 2 is a large and high-rise building. In particular, the ceiling height of the Great Hall Level 5 in the center of the IIA Terminal 2 is more than 26m. That is a huge atrium with 4 floors open in some spaces, from Level 2 to Level 5. The height of that space is more than 41m. It is not easy to composite comfort indoor environments in the huge space because of temperature stratification. The CFD(Computational Fluid Dynamics) simulation is the best method at the planning stage to predict indoor temperature and airflow distribution in a large space. The purpose of this study is to persue indoor environments comfort, indoor temperature and air velocity, for the occupant area(Z=1.5m) in the Great Hall. We investigated whether the air condition is comfortable in summer, considering interior heat gains and solar radiation. It was predicted using the turbulence CFD simulation with commercial code STAR CCM+in the large space. A steady-state CFD simulation was performed, and the cooling peak time was set to 1 PM by calculating the MEP cooling load. After analyzing the results of simulation with the initial plan of MEP, we identified the problems and suggested six improvements. 1) Adding inlets near the north curtain wall at level 5. 2) Adding inlets around the sunken space of Level 4. 3) Changing the air supply tower to a normal air supply(SA) of indoor booth. 4) Adding outlets(RA). 5) Adding and relocating SA, RA to Level 2, 3. 6) SA extraction angle adjustment. The results of CFD simulations are presented in this paper. The indoor temperature and air velocity distributions of final plan was simulated and comfortable environment conditions were confirmed.
