More than 190 experts from 22 countries participated in the 30th AIVC conference "Trends in High Performance Buildings and the Role of Ventilation" in Berlin at the beginning of October 2009. About 60 presentations split up into two tracks were held. The first track focused on future-oriented energy concepts for buildings whereas the second track dealt mainly with ventilation and indoor air quality. Experts presented studies and investigations of net zero energy buildings, energy efficient communities and optimised ventilation strategies for specific buildings like parliament buildings, dining halls and low-income dwellings. Trends in ventilation included hybrid ventilation for residential buildings, adaptive comfort models, efficient mechanical ventilation systems and the reduction of ventilation losses.
The conference was organised by the Air Infiltration and Ventilation Centre of the International Energy Agency together with Energie- und Umweltzentrum am Deister (E-U-Z) and the Fraunhofer Institute for Building Physics. In parallel to the AIVC conference the international symposium on "Airtightness of Buildings and Ductworks" took place accompanied by an exhibition of industry developments in this field. The conference papers will be offered soon for download on the AIVC website (http://www.aivc.org/).
