MATHEW, M. ... et al., 2019. Should current indoor environment and air quality standards be doing more to protect young people in educational buildings? To be presented at the 9th CIBSE Technical Symposium, Sheffield, UK, 25-26 April 2019.
Indoor environmental quality (IEQ) and indoor air quality (IAQ) were assessed in a recently
refurbished educational building at Loughborough University, through a monitoring
campaign in accordance with Building Bulletin (BB) 101. A particular focus of this work
was on emissions from building materials. Volatile organic compounds (VOCs) were
measured using diffusive (passive) methods involving Thermal Desorption (TD), Gas
Chromatography (GC) and Mass Spectrometry (MS) techniques. The results show that
although the building performs satisfactorily with respect to guidelines for overheating and
ventilation performance according to BB101 (2018) the current guidelines only assess
Total Volatile Organic Compound (TVOC) limits which fail to identify the source of IAQ
problems. The presence of numerous VOCs indicates that quantification of individual
compounds is necessary to assess long-term health risks.
