Analysis of the effect of air layers on traditional roofs On the thermal and cooling losses of the building

Abstract

The air layers in traditional roofs affect the thermal exchange of the roof. In this study, using carrier computing software, the effect of these air layers on the thermal and cooling losses of the building is investigated. For this purpose, two examples of dome roofs (with different air distances) have been considered and by comparing their heat and cold losses with today's flat roofs, the effect of these air layers has been investigated. The results show that the total total heat and cold losses in one year, for a flat roof with solid brick pressure compared to the traditional roof with one air layer, about twenty-six and a half percent and compared to the traditional roof with two air layers, about thirty And six percent more. Similar results were obtained for thermal and refrigeration losses in heat and cold peak loads, for ceilings with solid compression bricks and with clay bricks (with air cavities). Based on these results, it is possible to explain why buildings with traditional architecture, both in winter and in summer, can provide more comfortable conditions.
