Abstract(s)
Em consequência da elevada permanência das pessoas, essencialmente idosas e não só, nos espaços interiores dos edifícios situados em zonas climatéricas rigorosas, tem vindo a surgir uma maior preocupação com o conforto térmico e qualidade do ar no seu interior.
Apesar da enorme evolução dos sistemas de conservação de energia térmica e controle da qualidade do ar interior na construção, assim como da regulamentação que rege a sua implementação, 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 atividades dos seus utilizadores.
Com este estudo pretende-se caracterizar as condições de habitabilidade no interior de dezasseis edifícios situados no centro histórico de Bragança, mais propriamente na Cidadela da cidade, edifícios estas caracterizadas por serem de pequeno porte, com pouca luz natural e raramente alvo de trabalhos de reabilitação térmica.
Desta forma, foram analisados os principais parâmetros de natureza higrotérmica no interior de edifícios habitados, escolhidos aleatoriamente, tais como: a temperatura e a humidade relativa, assim como o estado de degradação do edifício, procurando a existência de patologias quer exterior quer interiormente.
Foi igualmente feito neste estudo uma avaliação energética de dois desses edifícios, apresentando diversas soluções construtivas entre outras, que se considera poderem contribuir para o aumento da eficiência energética e conforto dos seus ocupantes.
As a consequence of the high permanence of people, mainly elderly and not only, in the interior spaces of buildings situated in strict climatic zones, a greater concern has been expressed about the thermal comfort and air quality inside. Despite the enormous evolution of the thermal energy conservation and indoor air quality control systems in the construction, as well as the regulation that governs its implementation, the existing buildings do not follow this evolution, presenting a thermal and hygrometric behavior that sometimes can compromise both the comfort, health and activities of its users. This study intends to characterize the habitability conditions inside sixteen buildings located in the historical center of Bragança, more precisely in the city's Citadel, buildings characterized by being small, with little natural light and rarely the target of rehabilitation work thermal. In this way, the main parameters of hygrothermal nature inside inhabited buildings, chosen at random, such as: temperature and relative humidity, as well as the state of degradation of the building, looking for the existence of pathologies both outside and inside. In this study an energy assessment of two of these buildings was also carried out, presenting several constructive solutions among others, considered to be able to contribute to increase the energy efficiency and comfort of its occupants.
