Full Description
A Danish town hall with substantial complaints of poor indoor air quality is examined in this paper. The use of tracer gas measurements, which play an important part in the detection and solution of the problems, is described. Investigations are carried out both in the field and in the laboratory using a full-scale mock-up of a typical office. Contaminant sources are simulated by means of tracer gas to examine the effectiveness of the ventilation. The exposure of a seated person is assessed by means of a breathing thermal manikin. The results show poor ventilation effectiveness and serious thermal discomfort. A new strategy for heating and ventilation is found and tested in the laboratory and verified in the field.
