Einfluss der vom menschlichen Körper absorbierten Solarstrahlung für das Wärmeempfinden in Gebäuden

Influence of solar radiation absorbed by the human body on the thermal sensation of building occupants.

One of the key aspects of sustainable building is the well-being of occupants, which is greatly influenced by indoor climate conditions. Thermal comfort is a vital ingredient of satisfaction with people?s surroundings. It is to be expected that solar radiation will have a favourable influence on indoor social areas particularly in the winter months when radiation is predominantly diffuse. In contrast, direct exposure to sunshine in summer or on very sunny days in winter can quickly make people feel uncomfortable near windows and this must be counteracted by appropriate measures to protect them from the sun. The significance of solar radiation for the thermal sensation is illustrated on the basis of a further development of Fanger?s approach by means of simulations. The main results are summarised in this article.
