Can collected hygrothermal data illustrate observed thermal problems of the façade?:A case study from Greenland
Buildings are more vulnerable to faults in design and construction, when exposed to the extreme Greenlandic climate, however, most new materials and designs have not been tested for Arctic conditions. Thus even minor errors can result in failures like mould growth, discomfort, and unnecessary heat l...
