Abstract(s)
Em consequência da elevada permanência das pessoas em espaços interiores de edifícios, surge
actualmente uma maior preocupação com o conforto térmico e qualidade do ar no seu interior.
Apesar da grande evolução tecnológica dos sistemas de conservação de energia térmica e controle
da qualidade do ar interior (QAI) na construção, os edifícios existentes acabam por não
acompanhar essa evolução, apresentando um comportamento térmico e higrométrico que por vezes
podem comprometer quer o conforto, quer a saúde e actividades dos seus utilizadores.
Nos estabelecimentos de ensino, o comportamento termo-higrométrico assume um papel
importante face à permanência diária de um grande número de crianças e jovens no seu interior.
Com este estudo pretende-se caracterizar a qualidade do ambiente no interior de oito escolas,
através de uma análise aos principais parâmetros de natureza higrotérmica de oito salas de aulas,
tais como: a temperatura (ambiente e superficial), a humidade relativa (do ambiente e da superfície
da envolvente exterior opaca), bem como o nível de escoamento do ar interior.
Neste trabalho são apresentados os resultados das medições efectuadas em oito salas de aula que
permitiram a comparação de características termo-higrométricas entre as respectivas escolas. É
ainda apresentada a estimativa do nível de conforto térmico face às condições ambientais
registadas, bem como a análise do risco de ocorrência de condensações interiores.
As a result of the increased amount of time that people tend to stay indoors nowadays, it has grown the concern about thermal comfort and air quality. Although there is a huge technological evolution on the thermal energy conservation systems and indoor air quality, on construction nowadays, the preexisting buildings are not following the evolution, ending up presenting a thermo-hygrometric behavior that can sometimes jeopardize the comfort, health or activities of its users. With that in mind, and due to the great amount of children and young people, it can be understood why the thermo-hygrometric behavior plays an important role in schools. The purpose of this study it is to characterize the indoor environment quality in eight schools, through a detailed analysis of the hydrothermic main parameters of eight classrooms, such as: the temperture (environment and surface), the relative humidity (environment and engaging surface), and the air flow level. This dissertation presents the results of measurements made in eight classrooms, that have allowed the thermo-hygrometric characteristics comparison between all eight respective schools. It is also presented, in order to supplement the theme, the estimated level of termal confort, due to the acquired environmental conditions, and interior condensation risk analysis.
