There exist several initiatives in different parts of the world to bring a stronger basis to ventilation requirements in relation to indoor air quality and health issues, for example, at LBNL in the US (Healthy efficient homes program), within the HealthVent project in Europe (2010-2012), at Health and Wellbeing project in Japan, Development of healthy and clean residential building standard in Korea (2008-2012) or within the French Observatory for Indoor Air Quality (running since 2001). It would be beneficial for these projects to exchange information, for instance through webinars, workshops, etc.
