Abstract
This paper, presented at CRRELs First International Conference on Snow Engineering, addresses the how the use of glazed roofs at high latitudes creates special problems. One of these is snow load on the roofs. The snow load will be reduced because the snow will begin to melt if the accumulatoin is above a certain thickness. This thickness can be calculated dependent on the indoor temperature, outdoor temperature, thermal conductivity of the snow and the U-value ofthe glazing. In the figures are found calculations of different cases. The thickness of the snow and melting are given in a table. The theoretical results have been confirmed with pictures of a glass roof in Trodenheim. A recommendatoin for dimensioning of a roof above a heated glazed space is given.
