Indoor Air Quality in Offices

Since multiple studies have addressed IAQ and associated exposure-related symptoms in office workers, a careful assessment and management of indoor air quality (IAQ) in office-like environments is important for the protection of human health and to ensure optimal comfort and well-being for office workers. For this purpose, the development of appropriate monitoring strategies is crucial to properly characterize the chemical and physical complexity of IAQ dynamics and subsequent potential impacts on office occupants. To obtain comprehensive and representative conclusions about IAQ problems in office-like environments, and to prioritize the order of management interventions, a multilevel approach should be implemented. The assessment process should include a general survey of the building and of the offices, occupants’ questionnaire surveys (concerning IAQ, symptoms, and psychosocial working aspects), and environmental measurements. IAQ monitoring and assessment, combined with source identification and control and adjustment of ventilation rates, has been recognized as the prioritized strategy for improving IAQ in office-like environments and reducing the combined health risks associated with indoor exposures.
