Airtightness change in new buildings- causes and consequences

The aim of the project is to investigate the change in airtightness over time in concrete building and wooden buildings, and to describe the consequences of these changes, depending on leakage location. The investigations are made using airtightness measurements of real buildings, in combination with air leakage search and thermography. Detailed calculations will be made on a selection of details. The project results in a description of how the airtightness changes over time (concrete and wooden construction), from the point of completion to end state, and a description of the consequences of leakages in different locations. The material will contribute to a knowledge base and tools for assessing air leakage and following consequences.
