Desk two-1 incorporates data from two experiments (Haverinen et al., 2001a; Nevalainen et al., 1998) that utilized inspections by qualified staff to assess the prevalence of signs of dampness. Just a few scientific studies have analyzed differences among occupant-claimed and investigator-confirmed prevalence of moisture and mildew observations in structures. Douwes et al. (1999) located that occupant's reports of damp spots or mildew places had been greater correlated which has a measure of indoor mould than investigator's reports of these seen signals.
