The present report is mainly a reference source covering details in concrete constructions with low thermal bridge values, in many cases also showing specific air tightness measures. Chapter 2 describes the Passive House concept, including definitions, criteria and main principles, and also methods to achieve low thermal bridge values and sufficient air tightness. In this context, the term thermal bridge free design and calculation methods are discussed. Chapter 0 and 4 give a survey of existing guidelines and recent research results, on which the comprehensive list of details in chapter 0 is based. The details are arranged according to their position related to the building envelope. Every detail contains a description of the construction (in most cases including related U-values), a drawing and corresponding thermal bridge values. In addition, some overviews of foundation and support solutions as well as thermal separation products and U-values for fixing devices are compiled in the annex. This topic requires divulgation at a national level. For that reason, the report has been written in Norwegian and the translation is limited to this summary.
