Abstract

Thermal bridges have significant influence at calculation of the energy performance classes of buildings. This especially applies to countries where energy performance classes of buildings are determined based only on energy consumption for heating (such as Serbia, Bosnia and Hercegovina, Croatia...). Significant differences arise in determining the heat losses due to thermal bridges. Differences that can occur by using simplified methods depending on national recommendations of different countries are shown in this article.
