Abstract: This paper focuses on ANSYS Fluent simulations of the effect of floor heating, mixing ventilation, furniture, room geometry and their combinations on the interior heat transfer coefficient (HTC) of a typical office room. The results show an inhomogeneous distribution of the HTC on the exterior walls. HTC values are generally below the German standardised value for thermal protection, leading to an overestimation of the heat transfer losses by the standardised value. However, compared to the standardised value for the prevention of mould growth, the minimum surface averaged HTC behind closets is 63 % lower, potentially leading to condensation.
