Abstract(s)
O desenvolvimento de diversas tecnologias de produção de energia sustentável e a sua disponibilidade em mercado, permitem que nos dias de hoje seja possível ter sistemas mais eficientes, com menor impacto ambiental e com maior valorização dos recursos endógenos. Os sistemas sustentáveis de geração de energia elétrica e calor, podem ser aplicados na maioria dos edifícios, além das vantagens energéticas destes sistemas sustentáveis, estes requerem modestos acréscimos de investimento. Porém, existem situações em que a sua implementação simples não é possível, como e o caso dos edifícios antigos classificados como património histórico edificado, edifícios com limitações estruturais para os equipamentos de geração e edifícios cuja característica visual é de grande valor. O presente trabalho surge da importância dos sistemas sustentáveis de energia e o conflito com as suas dificuldades de implementação.
O trabalho expõe conceitos e apresenta alguns dos sistemas de geração de energia sustentável através das fontes renováveis do vento, do Sol, da geotermia e da biomassa. Expõe os seus sistemas de conversão da fonte energética primária em geração de calor e de energia elétrica, o funcionamento dos sistemas face ao consumo, as tecnologias presentes no mercado e as suas taxas de potência e eficiência. Para exemplificar esta problemática são abordados alguns casos de edifícios patrimónios passíveis de reabilitação, para levantamento das possibilidades de implantação de cada tecnologia de geração de energia sustentável. Apresentando as necessidades de instalação para cada tecnologia e a análise da possibilidade de instalação nos edifícios escolhidos. Por fim, apresenta o resultado e a análise da viabilidade técnica e social do estudo.
Pretende-se que o carácter pioneiro do tema da dissertação contribua para o crescimento da sustentabilidade na reabilitação de edifícios antigos, para a modernização destes edifícios, atendendo as necessidades da sociedade contemporânea, sempre respeitando o património edificado das cidades. Contribui, igualmente, para o meio académico com a sugestão de novas tecnologias que precisam ser desenvolvidas, no setor das energias endógenas, específicas para a reabilitação destes edifícios.
The development of several technologies for the production of sustainable energy and their availability in the market, makes possible to have more efficient systems today, with less environmental impact and greater appreciation of endogenous resources. Sustainable systems for generating electricity and heat can be applied to most buildings, in addition to the energy advantages of these sustainable systems, they require modest investment increases. However, there are situations in which its simple implementation is not possible, for example, old buildings classified as historical heritage, , buildings with structural limitations for generation equipment and buildings whose visual characteristics are of great value. The present work increases the importance of sustainable energy systems and the conflict with their implementation difficulties. The work exposes concepts and presents some of the sustainable energy generation systems through renewable sources of wind, sun, geothermal and biomass. It exposes systems for converting the organic energy source into heat and electricity generation, a coordination of systems aimed at consumption, such as technologies present on the market and their power and efficiency rates. To exemplify this problem, some cases of a patrimonial building that can be rehabilitated are presented, in order to survey the possibilities of implementing each sustainable energy generation technology. Presenting as installation requirements for each technology and analysis of the possibility of installation in the chosen building. Finally, the result and an analysis of the technical and social feasibility of the study. The dissertation, with its pioneering spirit on the subject, contributes to the growth of sustainability in the rehabilitation of old buildings, to the modernization of these buildings, meeting the needs of contemporary society, always respecting the built heritage of cities. It also contributes to the academic environment with the suggestion of new technologies that need to be developed, in the sector of endogenous energies, specific for the rehabilitation of these buildings.
