Numerical Evaluation of Ventilation Performance in Children Day Care Centres
Viegas, JC; Nogueira, S; Aelenei, D; Cruz, H; Cano, M; Neuparth, NModelling of ventilation is strongly dependent on the physical characteristics of the building of which precise evaluation is a complex and time consuming task. In the frame of a research project, two children day care centres (CDCC) have been selected in order to measure the envelope air permeability, the flow rate of mechanical ventilation systems and indoor and outdoor temperature. The data obtained was used...
Environment and Health in Children Day Care Centres (ENVIRH) - Study Rationale ...
Araújo-Martins, J; Carreiro-Martins, P; Viegas, J; Aelenei, D; Cano, MM; Teixeira, JP; Paixão, P; Papoila, AL; Leiria-Pinto, P; Pedro, CBackground: Indoor air quality (IAQ) is considered an important determinant of human health. The association between exposure to volatile organic compounds, particulate matter, house dust mite, molds and bacteria in day care centers (DCC) is not completely clear. The aim of this project was to study these effects. Methods --- study design: This study comprised two phases. Phase I included an evaluation of 45 DC...
CO2 Concentration in Day Care Centres is Related to Wheezing in Attending Children
Carreiro-Martins, P; Viegas, J; Papoila, AL; Aelenei, D; Caires, I; Araújo-Martins, J; Gaspar-Marques, J; Cano, MM; Mendes, AS; Virella, DPoor ventilation at day care centres (DCCs) was already reported, although its effects on attending children are not clear. This study aimed to evaluate the association between wheezing in children and indoor CO2 (a ventilation surrogate marker) in DCC and to identify behaviours and building characteristics potentially related to CO2. In phase I, 45 DCCs from Lisbon and Oporto (Portugal) were selected through a...
