32nd AIVC Conference " Towards Optimal Airtightness Performance", Brussels, Belgium, 12-13 October 2011
Most European standards and national regulations about ventilation rates are based on indoor air quality assumptions in terms of contamination. On the other hand, indoor air humidity is important for human health as well. In case of high flow rates during the heating seasons in cold climates, the indoor air humidity tends to low values.
This presentation gives an overview of the influence of the local climate (ambient temperature and humidity) in 9 European countries at given flow rates and moisture sources. In case of low indoor air humidity, ventilation systems with humidity recovery might be an useful option. The simulations show which humidity recovery rate is necessary at which climate.
Besides the simulations, real measurement data of a project in Innsbruck (Austria) are presented.
