Abstract
Thermal bridges can occur at various locations of the building envelope and can result in increased heat flow, lower interior surface temperature, moisture and mould problems and additional transmission losses. The additional transmission losses lead to a higher heating and cooling energy need and use and are becoming especially interesting with so-called low energy or high performance buildings. ASIEPI has collected and analysed international and national information from up to 17 EU Member States plus Norway on the topic of thermal bridges in building.
