dc.description.abstractThe SINTEF building defects archive is an important source to knowledge on building defects in Norway. This study presents a review of defects investigated by SINTEF in the period 2017–2020, including 175 defect cases registered in 125 reports. The main goal is to understand the primary causes of process induced building defects today and which building elements may be considered as risk spots. The review shows that almost 3 of 4 defects is related to moisture, caused by sources as precipitation, condensation of humid indoor air or built-in moisture. Defects associated with the building envelope make up more than 70% of the cases, of which most defects are linked to exterior wall or roof constructions. The results from the present study have been compared to a review of defects reported in the archive during the period 1993–2002. The comparison reveals that the share of damages caused by precipitation is almost doubled, while the share of damages caused by humid air from the interior is approximately halved. The results imply that climate adaptation of buildings is important. As climate change causes more precipitation with higher intensities, the load on buildings increases and a larger focus on risk reduction and protection towards penetration of water from the outside is required.
