Abstract: A large office building has a 140 m atrium which is split into four sections: atriums 1, 2, and 3 and "a sky garden" which is the upper most atrium with trees and shrubs. The atrium was simulated first in EnergyPlus to obtain the correct surface conditions for the critical days and then in Star CCM+. The first CFD analysis showed uncomfortable temperatures on the upper balconies in each section in the summer months. The optimization of the jet nozzles angles, the additional components and the supply temperature adjustment has shown a promising improvement in the thermal comfort on the balconies.
