Information paper P189 of the European Project ASIEPI

Even in well-insulated buildings, thermal bridges are often neglected. A third of EU Member States have no real ‘good-practice’ guidance on thermal bridges in the framework of their building energy regulations. The quality of guidance in the remaining States is very varied.

Part 1 of this paper suggests topics that should covered in ‘good practice’ guidance, how it can be structured and presented, and how it can be related to building regulations and standardization.

This Part 2 of the paper presents selected examples of good-practice guidance on thermal bridges and associated construction details from around Europe, in the hope that this will inspire organizations that are planning to publish or improve their own construction details and guidance on thermal bridges & airtightness. Examples of passive house guidance/details are included.

The two papers are published together with an electronic archive (file 'thermal_bridge_good_practice.ZIP' on the ASIEPI website) containing over 60 documents. The papers have clickable links that open the individual documents. The ZIP file should be extracted to the same directory as this PDF for the links to work.

The target readership for this paper is organizations planning to publish or update their own construction details and guidance on thermal bridges & airtightness. It is also aimed at building authorities, standardization bodies, and energy agencies.
