This property is de pendent on the local moisture content. The experiments that lead to the detailed in formation on the dependence of diffusivity on moisture content are often very so phisticated. However, two recent exercises, as a part of the activities of an International Energy Agency Annex, have shown that a correct estimate of the mag nitude of the moisture diffusivity can provide useful information with regard to its application in hygrothermal analysis. This technical note presents results from a sim ple moisture absorption measurement that led to a good estimate of the moisture diffusivity of building materials. Results from measurements on a sample of spruce are presented.<\/jats:p>","DOI":"10.1177\/109719639902200409","type":"journal-article","created":{"date-parts":[[2007,3,11]],"date-time":"2007-03-11T03:37:55Z","timestamp":1173584275000},"page":"349-355","source":"Crossref","is-referenced-by-count":110,"title":["Moisture Diffusivity of Building Materials from Water Absorption Measurements"],"prefix":"10.1177","volume":"22","author":[{"given":"M.K.","family":"Kumaran","sequence":"first","affiliation":[{"name":"National Research Council of Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1999,4,1]]},"reference":[{"key":"atypb1","volume-title":"Soil Science Society of America Proceedings","author":"Bruce R."},{"key":"atypb2","volume-title":"A Method to Analyze the Transient Hygrothermal Behaviour of Building Materials and Components","author":"Kohonen R.","year":"1984"},{"key":"atypb3","unstructured":"Kumaran M.K., Mitalas G.P., Ojanen T. and Kohonen R.
