Title:
Abstract:	Die Berücksichtigung von Wärmebrücken im Rahmen der Gesamtenergieeffizienz-Bewertung von Gebäuden erfordert häufig eine detaillierte Betrachtung im Sinne von durchzuführenden Wärmebrückenberechnungen. Für Bauelemente wie Fensterrahmen und andere kann hierbei bislang auf die Referenz-Elemente gemäß DIN 4108 Beiblatt 2, Anhang F zurückgegriffen werden. Diese führen jedoch zu einem recht hohen Arbeitsaufwand bei der praktischen Anwendung. Ziel der hier vorgestellten Untersuchungen war es, vereinfachte Ersatzmodelle für Bauelemente zu entwickeln, die anstelle der aufwendigen Referenz-Elemente genutzt werden können. Auf Initiative des Verbandes für Dämmsysteme, Putz und Mörtel e. V. (VDPM) wurden im Rahmen eines Forschungsprojektes [6\| Ersatzmodelle entwickelt, die hinsichtlich des Wärmeverlustes (ausgedrückt durch den &psgr;- Wert) und der niedrigsten Oberflächentemperatur &thgr;si, min zu Berechnungsergebnissen führen, die mit denen der Referenzmodelle vergleichbar sind. Thermal bridge calculation for building elements - development of simplified universal replacement systems The consideration of thermal bridges in the context of energy performance assessment of buildings often requires a detailed thermal bridge calculation. For building elements such as window frames and others, it has so far been possible to rely on the reference elements according to German DIN 4108 Bbl.2. However, this will lead to a high amount of work in the practical application. The aim of the investigations presented in this article was to develop simplified models of building elements that can be used instead of the time-consuming reference elements. On the initiative of the VDPM (German Association of manufacturers of industrial mortar) substitute models were developed witch, with regard to heat loss (expressed by the &psgr;-value) and the lowest surface temperature &thgr;si, min, lead to calculation results that are comparable to those of the reference models.
