Field tests of thermal insulation and airtightness of buildings Faltprovning av byggnaders varmeisolering och lufttathet

Treats methods of determining energy losses in a building given in 1975 swedish building regulations. Presents findings of a number of measurements using pressure method and thermography carried out during 1977 and winter of 1978. The apparatus and methods have been developed for field work. Presents results which depict different grades of airtightness in different types of building. Discusses use of thermography, which has been extensively used in recent years in Sweden in particular for new buildings. States method has been developed to become subject of a swedish standard. Regulations have also been drawn up to cover personnel carrying out thermographic tests on buildings.
