A method to assess the health and comfort changes among tenants after draught proofing of their flats.

The aim of the present study is to measure the possible health effects among tenants after certain characteristic energy conservation measures had been taken in their dwellings. Changes in comfort are also included. It is part of a number of projects on subjects such as indoor pollutant source control and changes in house dust mite populations related to moisture changes in retrofitted dwellings. The concept of combining different methodological studies like this is based on experience from other fields of environmental health studies in that they generally should include both field measurements and observational health studies, as well as controlled exposure studies, to be conclusive. This is an interim report of the study.
