Abstract:Diplomska naloga obravnava več načinov izračuna prispevka toplotnih mostov na skupne toplotne izgube skozi ovoj stavbe. Predstavljene so teoretične osnove prenosa toplote skozi konstrukcijo v območju toplotnih mostov. Iz ustreznih mednarodnih standardov so povzeti postopki za detajlni izračun in poenostavljene metode izračuna dolžinskih toplotnih prepustnosti. Za najbolj tipične toplotne mostove je z računalniškim programom izveden detajlni numerični izračun za različne debeline slojev. Odvisnost je opisana z empiričnimi izrazi. Primerjava s privzetimi vrednostmi iz standarda je pokazala, da te vrednosti niso vedno primerne za uporabo.

Title:ANALYSIS OF THE PRECISION OF SIMPLIFIED METHODS FOR THERMAL BRIDGES
Abstract:The thesis elaborates various calculation methods of thermal bridges’ contribution to the total heat transfer through building envelope. Theoretical basis of heat transfer through the thermal bridge region is presented. Detailed calculations and simplified methods for linear thermal transmittance are summarised from corresponding international standards. Using a computer software, detailed numerical calculations are performed for the most common types of thermal bridges with different layer thicknesses. Dependence on thickness is described by empiric expressions. Comparison to default values from the standard has shown that these values are not always appropriate for use.
Keywords:building physics, thermal conductivity, thermal bridges, linear thermal transmittance, simplified methods, detailed calculations
