Originální abstrakt

This article deals with the condensation risk of the top envelope of low sloped roofs with air ventilated cavity. Although the design principles in Slovak and Czech Republic are almost similar in consideration of the same history as well as current development of normative requirements, both have different implementation to their own standards at national level. The aim of this paper was to point out some consequences in building practice which can be caused by absent of requirements in Slovak standards as well. The consequences of non-adequate design of these types of roofs are demonstrated by numerical approach. In this context, the paper presents results of numerical analysis, where thy sky radiation influence is taken into account. The significance of sky radiation plays an important role in the radiation heat exchange during night-time with regard to surface temperature progresses and condensation risk at the top roof envelopes.
