Analysis of influence of a roof construction on indoor thermal stability in summer season
 Hofman, Petr ; Katunský,, Dušan (referee) ; Hirš, Jiří (referee) ; Mohelníková, Jitka (advisor)
The design of the building must respect the basic conditions for ensuring thermal comfort in the living space. The thermal comfort is influenced by several factors and one of them are the constructions of the building envelope. This work was focused on investigating influence of roof structures. The goal was to make analysis of influencing the selected modifications of the roof compositions to the thermal stability in the summer formed by experiments and detailed computer simulations. On the basis of these findings were defined suitable modifications. It has been worked out that the maximum indoor air temperature can be reduced by up to 1.5 °C in a suitable way. The cool roofs, thermal inertia and the ventilated air cavity layer have the greatest benefit. When evaluating the return on investment in a roof with high thermal inertia represented by a concrete layer of 100 mm, its return compared to a light roof and airconditioning is 12.1 years. The return on installation of external blinds on roof windows is 3.3 years compared to airconditioning.
