Summary

The relation between building physical characteristics and indoor environment in children day care centres (CDCCs) has received increased attention in the past decades as statistics on respiratory illness in children continue to cause concern. Although it is well known that ventilation plays a key role in maintaining acceptable indoor quality, there is a lack of studies exploring the relationship between ventilation rates, pollutant sources and health in day care centers in Portugal. The present study is part of the research project "Environment and Health in Children Day Care Centres", and aimed at surveying the ventilation characteristics of a number of 16 CDCC´s located in the cities of Lisbon and Oporto using a passive tracer gas technique which uses perfluorocarbon tracer gases. The measurements of the tracers over a period of two weeks in January 2012, pointed out low specific air flow rates (or air change rate per hour, ACH), varying between 0.04 and 1.18 in Oporto and between 0.01 and 0.41 in Lisbon. The purpose of this paper is to present and discuss these results.
