The international community working in the field of indoor air research gathers every three years to discuss the state-of-the-art. In Nagoya, Japan, some 900 scientists from more than 50 countries met. More than 600 papers were presented in the form of keynote lectures, plenary lectures, lectures in technical sessions and posters. Special issues were discussed in 16 workshops. The papers have been published in four proceeding volumes with almost 4000 pages.
