Advanced thermal bridge driven technical developments
This ASIEPI Information Paper informs about actual technical developments to reduce the thermal bridge impact in buildings. Though the paper does not provide a full market survey it gives an idea of the variety of the different currently available developments.

Good practice guidance on thermal bridges and construction details - Part 1: Principles & Part 2: Good examples
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.
Those two Information Papers present 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.
P188 (Principles) 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.
P189 (Good Examples) shows a selection of good examples from different countries.

The two papers are published together with an electronic archive (download the document - 107 MB) containing over 60 documents. The two Information Papers have clickable links that open the individual documents. The ZIP file should be unzipped to the same directory as the two Information Papers for the links to work.
ASIEPI Information Paper P159
Analysis of execution quality related to thermal bridges
It is a well-known fact that thermal bridges can increase the transmission heat loss of buildings significantly, especially as we move towards higher and higher insulation levels in both our new and existing buildings. Thermal bridges have been the focus of many studies in Europe over the last decades and today we have at our disposal highly developed calculation tools along with thermal bridge atlases for assessing their effect. This presents an opportunity to minimise thermal bridge effects during the design phase of a building project; however, in the transition from theory to practice there is a risk of introducing thermal bridges due to faulty execution.
A study was set up to quantify the effect of thermal bridges due to faulty execution. The study encompasses two different analyses: 1) a survey among the participating Member States concerning previous individual national studies on the influence of execution quality and 2) a questionnaire containing questions pertaining to methods for assessing and stimulating execution quality, i.e. an attempt to quantify what affects the execution quality.

Software and atlases for evaluating thermal bridges
Different tools are available for evaluating thermal bridges. This paper provides information on software and atlases that are frequently used in the Member States. The European/International standard EN ISO 10211 is also briefly presented: it establishes the conventions to be followed when modelling thermal bridges, and provides elements for the validation of software.

Impact of thermal bridges on the energy performance of buildings
Thermal bridges have influence on the surface temperature of building components, but also on the energy performance of buildings. The ratio of losses due to thermal bridges to the total transmission losses is small in existing, non-retrofitted buildings but can become quite considerable in new and especially in high performance buildings. This paper summarizes studies on the impact of thermal bridges on the energy performance of buildings in different European Member States and gives therefore an indication on the relevance of including detailed thermal bridge assessments in the EPBD calculation methods.

Thermal bridges in the EPBD context: overview of MS approaches in regulations
The Information Paper summarizes the thermal bridges requisites, calculation and controls procedures by authorities in participating countries. The work was to collect and analyze the various approaches of Member States while dealing with thermal bridges and including them in the national Energy Performance Calculation Standards. The Information Paper summarizes results splitting countries in three climatic regions: North, Central and South Europe.
