Scenario
What a survey looks like
Rental flat, suspected mould in bathroom and bedroom. Three photos per room, humidity measurement, voice note "Old building, no ventilation system, north-facing exterior wall, visible infestation in bathroom corner ~0.8 m², bedroom skirting ~1.2 m²." Vision analysis classifies the infestation (mildew vs. black mould), suggests a remediation stage and pulls in the DIN 4108-2 thermal-bridge review. Draft including the recommendation "drying out + black-mould remediation category 2" is ready for approval that evening.
