Abstract: This simulation study was performed within the framework of IEA EBC Annex 68 and assesses two innovative ventilation concepts in terms Indoor Air Quality (IAQ), namely the extended cascade ventilation and the active overflow ventilation concept. Both aim at reducing costs and spatial requirements for mechanical ventilation with heat recovery (MVHR) in low-energy housing. In a simple co-simulation approach CO₂, formaldehyde and particulate matter (PM) concentration is evaluated for a representative Austrian dwelling. Besides sources and sinks for CO₂, humidity and particulate matter (size resolved), the temperature and humidity dependent emission rate of formaldehyde from building materials is modelled.
