27-28 March 2009 , Bratislava, Slovakia
Identify the exposure level in combination with building characteristics and occupant behaviour and activities
Analyse the passive samples
Compare the air quality data measured by the participating centres
Evaluation of the relationship between measured concentrations and possible emission sources
Draw the conclusions
IAQ-related health problems in schools
IAQ can potentially affect the health of students /staff in the educational process
Children are more susceptible to poor IAQ
Students spend 4-8 hrs a day in school
Magnitude of schoolchildren population
IAQ pollutants are 2 to 5 times higher
Within the school building
Polluted outdoor air (traffic, industry)
