Modelação da qualidade do ar interior em edifícios com ventilação natural

Abstract

A qualidade do ar interior (QAI) em edifícios é uma preocupação que acompanha o Homem desde há séculos. A qualidade do ar interior nas escolas, em particular, tem vindo a provocar um crescente interesse, dado que o grupo populacional pertence a um grupo etário mais suscetível de ser afetado. A utilização de ferramentas numéricas de modelação na avaliação da QAI é uma mais valia, pois permite estimar as concentrações dos poluentes no interior dos edifícios. O principal objetivo deste estudo consiste na avaliação da qualidade do ar interior através da aplicação de uma ferramenta a um caso de estudo. Neste caso de estudo estimou-se a concentração de material particulado (PM10) numa sala de aula da Escola Básica nº 1 da Glória, em Aveiro. Neste âmbito, foi aplicado o modelo INDEX, Indoor Exposure model, que possibilita o cálculo de concentrações interiores de poluentes atmosféricos. Os resultados da aplicação indicam que as concentrações do ar interior são influenciadas pelas concentrações exteriores e pela velocidade do vento. Note-se, contudo, que os valores simulados cumprem os valores legislados na Portaria nº 353-A/2013, de 4 de Dezembro. Embora os resultados simulados não revelem uma má qualidade do ar interior na sala de aula da Escola Básica nº 1 da Glória, a avaliação de outros poluentes seria um ponto de extrema importância, de forma a verificar se os requisitos da qualidade do ar interior estarão a ser garantidos.

The indoor air quality (IAQ) in buildings is a concern accompanying mankind for centuries. Particularly in schools, the indoor air quality has been causing growing interest because this population’s age group is more susceptible to be affected. The use of numerical modeling tools to evaluate the IAQ is an asset because it permits estimating the concentrations of the pollutants inside buildings. The aim of this study is to evaluate indoor air quality by applying a tool to a case study. In this case study, estimated the concentration of particulate matter (PM10) in Escola Básica nº 1 da Glória in Aveiro was estimated. In this context, the model INDEX, Indoor Exposure model, which enables the calculation of indoor concentrations of air pollutants was applied. Results obtained indicate that indoor air levels are influenced by external concentrations, and wind speed. Note, however, that the simulated values are within the legislated values in Portaria nº 353-A/2013 of 4th December. Although the simulated results do not show poor indoor air quality in the classroom of the Escola Básica nº1 da Glória, the evaluation of other pollutants would be a point of extreme importance in order to verify that the indoor air quality requirements are to be guaranteed.
