Abstract(s)
A eficiência energética deve ser considerada quando se constroem novos edifícios, mas também
quando se realizam trabalhos de reabilitação em edifícios existentes, de forma a obter um
comportamento térmico e um desempenho energético adequado às necessidades do edifício aliado ao
reduzido consumo de recursos.
A presente dissertação visa a adoção de medidas de reabilitação energética num edifício de
serviços, mais concretamente na piscina coberta da Academia Militar de Lisboa. Este edifício foi
inaugurado em 1986 e apresenta alguma degradação dos materiais construtivos da envolvente e dos
equipamentos, por falta de manutenção e requalificação, tendo um comportamento térmico deficiente
e consumos energéticos elevados.
Para mitigar os efeitos indesejados acima mencionados procedeu-se a um estudo de reabilitação
energética que consistiu na adoção de diversas medidas de melhoria, de entre as quais se destacam
a aplicação de isolamento térmico pelo exterior das paredes da envolvente opaca das fachadas e
cobertura; implementação de vãos envidraçados com caixilharia de PVC de vidro duplo ou triplo;
adoção do sistema de iluminação LED e alteração do horário de funcionamento das caldeiras.
Para tal, procedeu-se a medições in situ e a simulações energéticas do edifício com recurso ao
software Hourly Analysis Program, para determinação das necessidades energéticas do edifício antes
e após a implementação das medidas de reabilitação.
Posteriormente, efetuou-se uma análise da viabilidade económica de quatro propostas de
reabilitação energética, tendo-se concluído que a implementação das mesmas apresenta um impacto
significativo na redução de consumos energéticos e uma melhoria do comportamento térmico e
desempenho energético do edifício.
Energy efficiency must be considered in both new and retrofitting buildings. The main objective is to obtain appropriate thermal behavior and energy performance that prosecute building requirements coupled with reduced resource consumption. This thesis focuses the implementation of different energy rehabilitation measures in a service building, more specifically the indoor pool of the Military Academy of Lisbon. This building was opened in 1986 and presents some degradation of building envelope and equipment due to the lack of maintenance and requalification which conducts to inefficient thermal performance and high energy consumption. To mitigate the above mentioned undesirable effects a rehabilitation study based in the adoption of several energy rehabilitation measures was carried out, such as: application of thermal insulation on facades and on roof; implementation of glazed areas with double or triple glazing units with PVC window frames; adoption of LED lighting system; and change the operating hours of boilers, among others. To achieve this, in situ measurements and building energy simulations, using the Hourly Analysis Program software, were performed to determine the energy needs of the building before and after the implementation of rehabilitation measures. Furthermore, we performed an analysis of the economic viability of the four proposals for energy rehabilitation. We concluded that their implementation has a significant impact on reducing energy consumption and it improves the thermal and energy performance of the building.
