The aim this paper is to present the results of simulations of mechanical ventilation system performance in assembly hall of the Faculty of Environmental Engineering, Lublin University of Technology. Simulation was conducted using Autodesk CFD Simulation 2013. 3D model of the assembly hall was created in Autodesk Revit Architecture application, which is directly connected to CFD Simulation program. There were conducted two variants of simulations: for winter conditions and for the summer performance. Obtained results enable to verify temperature values and air-flow velocities in the modeled room in each place and time. Conducted simulations showed that there are the areas with air parameters do not satisfying the design assumptions, required for thermal comfort and the correction of the applied solutions is needed. Air flow velocity distribution in the examined assembly hall, determining the indoor air parameters depends on many factors that were not considered in the described system solutions. The most important factor is temperature of the external barriers and the particular geometry of the room. Their consideration was only possible after creating the spatial model of the room and the ventilation system.
