VOCs and aldehydes source identification in European office buildings - The OFFICAIR study

摘要

Indoor air quality (IAQ) measurements were carried out in two field campaigns (summer and winter) in European office buildings (approximately 140 office rooms) in eight countries, as part of the EU-funded OFFICAIR project. A source identification study was performed with principal component analysis (varimax rotation) on a database containing volatile organic compound (VOC) and aldehyde concentration data during summer and winter monitoring campaigns. The common indoor and outdoor sources of VOCs and aldehydes were identified through a critical evaluation based on checklist data and knowledge of material and product emissions from the literature.
