Hygrothermal assessment of external walls in Arctic climates: Field measurements and simulations of a test facility

The Greenlandic building sector is under pressure due to ever-changing trends and a shortage. Regrettably, there have only been made small efforts investigate the performance of existing buildings, few resources dedicated learning from previous attempts. Consequently, available information research are insufficient ensure construction robust well-functioning buildings. This knowledge gap motivated ABC project, which had goal collecting sharing about optimal practices in Greenland. As part this study aimed determine practice most suitable for conditions. To end, several real-time experiments were created, including test pavilion Nuuk consisting five different wall constructions oriented towards north south. article presents measured data pavilion. each type was compared with other simulations performed hygrothermal analysis software Delphin. Furthermore, robustness facades tested by performing weather towns Greenland, quantification mould growth risk using Viitanen model. It found that unevenly affected orientation. Nevertheless, none could be labelled unsuitable Arctic climate as assessments revealed no growth. Additionally, reanalysis ERA5 simulations. also favourable location future facilities.
