Abstract

The paper aims to elaborate engineering methods of calculating heat loss through combined roof constructions. Roof heat losses can reach up to 40% of total heat losses of a building and affect its energy efficiency class. In Ukrainian construction regulations there are no methods of roof heat loss determination which would take into account structural features. Combined roofing is a multi-layer envelope with variable thickness layers (for example, to create a slope for organized drainage system). Therefore, the total thermal resistance varies in different areas of the structure. This paper analyzes calculation of heat transfer coefficient of components with variable thickness layers according to PN-EN ISO 6946:2008 and proves the necessity of including the methods above in the Ukrainian guidelines for calculating heat transfer by transmission. The article is a continuation of the author's previous scientific research. The main papers are given in the bibliography.
