Odour problems in buildings – result of 682 cases

Abstract

Various odours can cause a negative perception of the indoor air quality. The intensity of the odour can fluctuate for example due to weather conditions, ventilation, and use of the building. In addition, the degree of odour perception among individuals, is highly variable. Absence of an adequate measuring method makes it difficult to get a systematic and uniform description of the odour and where in the building the odour is most noticeable. This leads to challenges in clarifying the causes and relevant measures are often difficult to submit. Examination of 682 cases with odour in dwellings and commercial buildings have shown that causes and remedial actions can be revealed by a systematic procedure. Complainers are asked to characterize the smell in few, standardised words and describe where and when they experience the odour. This information is often crucial for the surveyor when performing the following building examination.
