Description

Water leakage and dew condensation at residential attics are major cause for complaints in construction works. Discriminating these two phenomena is important, since countermeasure works for these two phenomena are different. This paper firstly proposes a wetting sensor monitoring system to detect these water films in attics. Secondary, sensor system stability under temperature, humidity change and chronic measurement is evaluated. Lastly, discrimination method for difference in flow conditions of water leakage and dew condensation is proposed.
