Abstract

Indoor air quality (IAQ) has significant impacts on office occupants’ productivity, well-being and health. Addressing IAQ not only means ensuring that contaminants are below harmful concentration but also that people exposed are satisfied. However, current standards often lack clear metrics and thresholds dedicated to Perceived Air Quality (PAQ). Therefore, it is important to examine whether there is a prevalent method in the literature that could lead towards standardization. This review study constitutes the first comprehensive critical exploration of the subject. Adopting the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, the objective is to synthesize and compare diverse methods (subjective vs instrumental evaluations; object of judgment; component of perception; rating scales) for assessing PAQ in office buildings, based on insights from 93 field and laboratory studies. Results show that the assessment of PAQ predominantly relies on questionnaires (90%), with a very smaller percentage using alternative methods such as olfactory indices, diaries, interviews, sensory testing, and text mining techniques. Workers’ satisfaction is the most commonly evaluated aspect in PAQ questionnaires, often measured on a 7-point Likertscale. Odours are typically characterized in terms of intensity by utilizing a continuous 6-point unidirectional scale. Olfactory stimuli are usually considered with a negative connotation, being the absence of odour the target of IAQ design. The present study proposes a future research agenda that introduces the importance of a perceptual approach to evaluate the indoor olfactory environments (or smellscapes), aiming to create working spaces that are not only odour-neutral but also olfactorily pleasant.
