Abstract [en]

Adaptive ventilation, controlled with respect to absolute humidity inside and outside a building, canbe used to reduce RH below risk levels for biodeterioration. In the present case study, adaptiveventilation was used in a historic stone building with severe moisture problems. Measurementscarried out over a year shows that ventilation had a significant drying effect. The mould risk is keptat an acceptable level with exception of two short periods .Short term variations in RH are acceptableaccording to conservation standards. Heating or dehumidification as an auxiliary measure would beneeded only for a short period of time. The performance can be improved by increased fan capacityand improving air tightness of the building.
