Outdoor/indoor air quality in primary schools in Lisbon: a preliminary study

Abstract: , and some indoor/outdoor ratios greater than unity, suggest that indoor sources and building conditions might have negative effects on air indoors. Increasing ventilation rates and use of low-emission materials would contribute towards improving indoor air quality.

“…All schools have natural ventilation and there is no forced ventilation or air conditioning system in use (ventilation is done by opening doors and windows). The data studied here is part of a larger study, which has been described and analysed in previous research (Almeida et al, 2011;Canha et al, 2010Canha et al, , 2011Pegas et al, 2010Pegas et al, , 2011aPegas et al, , 2011b.…”

“…The IAQ in school buildings is expected to be a key role player in the assessment of the effects of the children personal exposure to air pollution as children spend at least a third of their time inside school buildings, that is, approximately seven or more hours a day in school EPA, 2010;Pegas et al, 2010;Wheeler et al, 2009;Ramachandran et al, 2005). Poor IAQ can affect scholarly performance and attendance (Daisey et al 2003;Godoi et al 2009).…”
