The Commission is in the process of updating some of the content on this website in light of the withdrawal of the United Kingdom from the European Union. If the site contains content that does not yet reflect the withdrawal of the United Kingdom, it is unintentional and will be addressed.

In the new German regulation about energy performance of buildings EnEV 2009, the method to assess the equivalence of thermal bridges according to DIN 4108 Addendum 2 is rearranged. This should lead to a simplification of the evaluation of thermal bridges, but with the risk that thermal bridges are wrongly estimated. This article shows examples.

One of the documents that building designers like to use to take into account additional heat losses through thermal bridges is the Addendum 2 to DIN 4108. When details are planned and executed on the basis of this addendum, a flat rate value must be taken into account, avoiding complex calculations in accordance with European standards. However, problems occur especially when the actual details plans are not in accordance with those of the addendum. This book gives the basis for a proof of equivalence with the latest edition of DIN 4108 Addendum 2.
