This report presents background to and advice on methodologies for sensory evaluation of indoor air quality (IAQ). The report gives a short introduction to sensory mechanisms and responses and to the theory of measurement underlying sensory evaluations and discusses in detail available sensory evaluation techniques. After a critical methodological analysis of some recently published documents on IAQ, sensory methods best suited for the evaluation of material emissions and of IAQ and for population response studies are recommended. Also non-sensory techniques for the evaluation of odour and mucosal irritation are briefly discussed. However, it is concluded that, at present, human subjects are indispensable in the measurement of perceived indoor air quality. The proposed methods will enable designers, manufacturers, chemical and ventilating engineers, consumers, building and health authorities, and other decision makers to compare and select appropriate building materials, furnishings etc. Thereby the design, supply and control for good perceived air quality in indoor spaces will be easified which will lower the costs and minimize waste of energy.
