Can collected hygrothermal data illustrate observed thermal problems of the façade? – A case study from Greenland

Abstract Buildings are more vulnerable to faults in design and construction, when exposed the extreme Greenlandic climate, however, most new materials designs have not been tested for Arctic conditions. Thus even minor errors can result failures like mould growth, discomfort, unnecessary heat loss. Rekognizing source of error be difficult, yet valuable. But how it identified whether lies or quality workmanship? This paper describes a case study from Nuuk, Greenland, where mineral wool insulation system was implemented. Residents were complaining about draft cold areas. An investigation revealed that inaccurate use caused several problems. Simulations exterior wall performance conducted compared measurements. discusses these measurements simulations support issues, therefore if this kind general surveillance walls used determine total an wall. The concludes collected data issues complaints, fundamental reasons problems design, precision casted concrete lack wind barrier protecting insulation.
