Abstract

The paper is focused on the description of a principle of a thermal comfort measurement using a thermal manikin and methodology based on ISO 14505-2. The paper gives an example of the thermal comfort measurement in an office building during the winter season in Central Europe. The influences of environmental parameters and operational conditions of the office on thermal comfort are analysed. The anatomical thermal manikin, divided into 34 independently controlled and measured zones, was used for the measurements and the heat flows from all parts of the manikin were measured. Subsequently based on ISO 14505-2 the equivalent temperatures and thermal comfort were calculated. The measurements have shown the possibility of determining the thermal comfort using a thermal manikin and also influences of main sources of discomfort in the winter season: occasional ventilation through windows and loads from sun radiation. The results also show that measurement with a thermal manikin is a suitable approach for the evaluation of local thermal comfort and allows precise measurements of inhomogeneity and asymmetry of indoor environments.
