title = "Applications and development of IR techniques for building research in Finland",
abstract = "Infrared thermography has been used in building research at the Technical Research Centre of Finland (VTT) since 1975. Traditionally this technique has been used to localize defects in thermal insulation and air tightness in the external envelope of buildings. During the past few years it has also been applied successfully to assessing the condition of facades and detecting moisture in structures. This paper briefly describes our experiences with thermography in building research. Multispectral technique has been applied to concrete facades. The principle of this method is also presented in this paper.",
