Thermal comfort of an office building plays a big role in the productivity, and is the key factor in its design process. Parameters such as velocity and temperature distribution within office space can be computed with the help of Computational Fluids Dynamics (CFD) analysis. In this study SimScale platform will be used to evaluate the capabilities of CFD softwares to predict the temperature and velocity distribution within a simplified office building, having multiple heat sources.

The thermal mannequin has a surface area of 1.6 m2 and is modeled to generate convective heat equal to 59.8 W. This value corresponds to 37.4 W/m2. Heat emitted by the PC-simulator and the lighting simulator is set equal to 61.5 and 10.9 W, respectively. Each fluorescent lamp generates 18.1 W.
The purpose of this project is to validate the accuracy of the solver for indoor convective heat transfer. The velocity and temperature contours are to be compared with the proposed results.
