Abstract(s)
Este trabalho foca-se no desenvolvimento de estratégias e
soluções para a otimização energética de uma habitação turística, com o
fim de alcançar autossuficiência energética através da integração de
sistemas de produção de energia renovável. A relevância desta
investigação reside na necessidade urgente de mitigar os impactos
ambientais decorrentes do consumo energético proveniente de fontes
não renováveis, promovendo a sustentabilidade e eficiência energética
em edificações. A habitação em estudo, já construída, não foi
originalmente projetada com princípios de sustentabilidade, impondo
assim limitações e desafios únicos. O estudo procedeu com uma análise
aprofundada do desempenho energético atual do edifício e explorou
potenciais melhorias através de simulações energéticas e
dimensionamento de sistemas renováveis, considerando dois cenários:
um “Ideal”, que ignora as restrições práticas e visa a autossuficiência
total, e um “Real”, ajustado às condições e restrições existentes da
habitação. Nos cenários propostos, foram analisadas a viabilidade e a
eficácia de diferentes combinações de tecnologias renováveis, sempre
considerando o retorno do investimento ao longo de um período de 25
anos, a vida útil estimada do sistema. A análise revelou que o cenário
“Real”, embora não alcançasse a autossuficiência total, conseguiu
satisfazer integralmente as necessidades térmicas de AQS e
parcialmente as elétricas da habitação, demonstrando ser uma solução
tecnicamente viável e economicamente rentável, com um retorno do
investimento em 9 anos. Este trabalho não só valida a aplicação prática
de soluções renováveis em habitações já existentes, mas também
destaca a importância da adaptabilidade e inovação contínua em projetos
de sustentabilidade energética, contribuindo significativamente para a
literatura existente e para futuras implementações em edifícios
residenciais.
This study focuses on the development of strategies and solutions for energy optimization in a touristic dwelling, aiming to achieve energy self sufficiency through the integration of renewable energy production systems. The importance of this research is highlighted by the urgent need to mitigate the environmental impacts arising from energy consumption from non-renewable sources, promoting sustainability and energy efficiency in buildings. The dwelling under study, already constructed, was not originally designed with sustainability principles, thus imposing unique limitations and challenges. The study proceeded with an in-depth analysis of the current energy performance of the building and explored potential improvements through energy simulations and sizing of renewable systems, considering two scenarios: an 'Ideal' one, which ignores practical restrictions aiming for total self-sufficiency, and a 'Real' one, adjusted to the existing conditions and restrictions of the dwelling. In the proposed scenarios, the viability and effectiveness of different combinations of renewable technologies were analyzed, always considering the return on investment over a period of 25 years, the estimated lifespan of the system. The analysis revealed that the 'Real' scenario, although it did not achieve total self-sufficiency, managed to fully meet the dwelling's thermal needs for DHW and partially the electrical ones, proving to be a technically feasible and economically profitable solution, with a return on investment in 9 years. This work not only validates the practical application of renewable solutions in existing dwellings but also underscores the importance of adaptability and continuous innovation in energy sustainability projects, contributing significantly to the existing literature and future implementations in residential buildings.
