The current thermal properties of building external structures including openings are supposed to suppress effects of draft to thermal comfort. But is it true expectation? The subject of the paper is the analysis of airflow around the window in three types of heating systems with predominant radiant as heat transfer. The analysis is based on experiments in the climatic cabin representing the room of a low-energy family house. To obtain the relevant data, a series of particle image laser velocimetry measurements were performed to visualize and quantify the airflow in the investigated area. The paper present results of the thermal comfort of the inhabitants of the room, which prove that with the influence of draft it is necessary to count on modern energy-saving buildings. They prove that old well-known rules about the position of the heating surface apply to the most cooled constructions and bring interesting conclusions about underfloor heating.
