The Air Infiltration and Ventilation Centre (AIVC) together with Fraunhofer IBP in Germany organize a workshop entitled “Indoor Environmental Quality in Sustainable Buildings" to be held on 1-2 April 2025 in Stuttgart, Germany.
The 1 ½ day workshop provides the opportunity to German researchers and engineers, as well as international experts, to present and discuss recent developments in relation to indoor environmental quality, ventilation, health and sustainability of the building stock.
This workshop is part of a series of annual international workshops, which are organized by AIVC in collaboration with national research centers or energy authorities. These workshops also target regional issues in relation to ventilation and infiltration, as part of a process of knowledge generation.
The following sub-themes will be addressed:
- Status of implementation of EPBD recast
- IAQ in relation to health
- IEQ in sustainable buildings
- Case studies in schools & care facilities
- Demand and personal control, user interaction
