Finding F-0545

“Surface Mould Contamination in Dwellings Out of all dwellings in which occupants reported the presence of visible moulds in 2015–2016, 74% were confirmed in the lab to be contaminated by actively growing fungi.”

Structure

Factor: Mould
Population: households in energy-efficient dwellings
Setting: dwelling, CH
Study design: survey and sampling of 149 energy-efficient dwellings in Switzerland (44 recent, 105 retrofitted; natural or mechanical ventilation): occupant questionnaire on visible mould, surface samples cultured for actively growing fungi, bedroom settled dust (class 4)
Effect: prevalence 74
Sample: 149 homes
Caveat: confirmation rate of reported mould, not a prevalence in all dwellings
