Indoor mould is one of the most important determinants of indoor air quality, with serious implications not only on human health, but also on the building envelope itself. This study is based on the Chadwick building, which is a late 19th century building, currently under the ownership of UCL as a workplace and school. Therefore it brings together different functions which are conventionally discussed separately in the relevant literature. This study aims to measure airborne and surface mould concentrations within the Chadwick Building, and to find out the correlations between these and the physical characteristics of the tested spaces. To this end, 3 classrooms, 3 offices, 3 laboratories, and 1 activity room were sampled to examine the airborne (active or aggressive) and surface mould concentrations. Samples were analysed for the β-N-acetylhexosaminidase (NAHA) activity to determine the fungal cell biomass at the laboratories of Mycometer in Denmark. The testing protocol also involved active particle counting, and temperature and relative humidity measurements. Offices were found to be the least mould intensive spaces, while laboratories were found to have the highest level of mould and particle intensity among all tested spaces. Based on the benchmarks previously established for residential indoor environments (currently in use by the Danish Building Institute), the results showed that most of the tested spaces did not have no mould and with a good/normal cleaning standard. Only one space and a few surfaces indicated either a minor (most likely non-building-related) mould, or a poor cleaning standard. The validity of these categories for a workplace/school should be further investigated by future research.
