      <subfield code="a">This article reviews the sources levels, and interpretation of CO2 and volatile organic compounds (VOC) concentrations in buildings. The use of an enrichment factor to identify emission sources and potential indoor air quality (IAQ) problems is suggested. The indicator is evaluated by collecting concentration data in two office buildings and by reviewing recent air-quality studies in the literature</subfield>
