This paper deals with field experience of airborne moisture transfer problems in houses. Two types of phenomena are discussed in more detail; the infiltration of moist air from crawl spaces and the propagation of moist air produced in kitchens. A modified depressurisation test is described to determine the air tightness of ground floors. A case study is briefly discussed where different remedial measures have been tested to evaluate the moisture removal effectiveness in kitchens.
This paper reviews research activities undertaken in the framework of IEA Annex XIV, "Energy and Condensation". It outlines the objectives and working scheme. The importance of ventilation as an influencing factor and a remedial measure is investigated. The central theme of the IEA workshop, held in Leuven in September, 1985, was the problem of condensation.
