... to the building regulations a ventilation rate of between 0.5 and 1.0 air changes per hour is considered sufficient to prevent moisture development in the air; and the relative humidity should not exceed 70 per cent for a prolonged period to avoid the consequent risk of condensation and mould growth. This may...

... with continuous monitoring of the relative humidity and temperature, to validate the real climatic conditions in the crawl spaces. Additionally, the authors analyse the treatment technologies used in the past and the characteristics of the rehabilitation solutions in order to control the hygrothermal behaviour...

... is the airflow, which has two aspects – the quantity of the air flow and flow characteristics. The airflow provides conditions for the system to both dry out water in the construction and also to keep the relative humidity at a low level, which will prevent mould from growing. A predictable airflow out...

... per cent relative humidity (RH). Mould needs satisfactory temperature, enough time and at least 75 per cent RH to grow. When the humidity rises, the growth of the mould will become more rapid (Sedlbauer, 2001). The possibility to remove dampness inside walls and intermediate floors has not been...
