Zhao, S and De Angelis, E (2020) Reducing mould risk during the building design stage: Case studies in South-East China. Journal of Construction in Developing Countries, 25(1), pp. 1-20. ISSN 1823-6499
Abstract
Indoor mould is usually discussed for the building operation phase rather than the design stage. Moreover, the majority of existing studies were conducted by mechanical engineers rather than architects, who typically have a broader view of the whole project. The purpose of this article is to obtain a quantitative mould risk scenario across the Yangtze River Delta in China and make a matrix including all the possible design options to reduce the mould risk. A series of software is utilised to simulate the mould risk in three main cities across that region. Simulation results confirm high mould risk in all selected cities and the mould growth rates in different orientations match the Wind-Driven Rain diagram. After the simulation, all factors that can be tuned for the mould prevention were analysed. It is found that only humidity and substrate (material of finishing layer) characteristics can be practically controlled for mould avoidance. Meanwhile, the development design stage is the essential design phase while the envelope is the most crucial building element for mould prevention.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
