The sound intensity technique and reverberant sound excitation have been used for the measurement of sound transmission loss through narrow slits in rigid walls. As predicted by theory, the dimensions of the apertures determine the magnitudes andresonant frequencies of the sound transmission loss curves. It should thus be possible in principle to size air leakage cracksusing the technique described in this paper.

Within the framework of the Dutch participation in IEA Annex XIV "Condensation" field experiments have been carried out to study airborne moisture transport in realistic circumstances. The experiments were done in an unoccupied 3-storey dwelling in Leidschendam in the Netherlands. The paper discusses some of the results.

The idea to start an Annex on mould, surface condensation and energy grew in 1984-1985. In September 1985, a workshop was organised at the Leuven University, Belgium, focusing on the state of the art in different countries. This workshop reve
