Abstract(s)
A eficiência energética e a descarbonização do ambiente, são temas que merecem uma
crescente preocupação por parte dos centros de investigação, organizações nacionais e interna cionais. Desta forma, existe uma preocupação na reabilitação energética dos edifícios e o estudo
de medidas de melhoria que têm como principal foco tornar o edifício um NZEB (Nearly Zero
Energy Building).
Os Decretos-Lei emitidos pelos estados-membros da União Europeia, possuem diversos
objetivos e proporcionam metodologias de cálculo do desempenho energético, estabelecendo
requisitos mínimos para os edifícios novos.
A presente dissertação aborda a execução da certificação energética num edifício de
serviços, aplicando os métodos de cálculo num caso estudo.
Pretendem-se levantar propostas de melhoria que contribuem para o aumento do desem penho energético e, favorecem a diminuição de consumo energético. Por fim, procura-se reali zar o plano de manutenção dos diferentes sistemas presentes no edifício, de forma a prolongar
a vida útil dos mesmos.
A finalidade é demonstrar que as medidas de utilização racional de energia propostas
no certificado energético contribuem para o aumento da eficiência energética e da sua susten tabilidade. Estas promovem a diminuição de consumos energéticos e, consequentemente, a di minuição das emissões de gases com efeito de estufa.
A evolução e o aumento do nível de exigência da certificação energética em Portugal
contribuem para limitar o consumo energético das habitações, dos edifícios de comércio e ser viços, ao incentivar, principalmente, a renovação das edificações existentes, desprovidas de
eficiência energética quando comparadas com construções novas.
É de extrema importância promover um maior nível de conforto térmico, reduzir a po breza energética e incentivar o consumo a partir de energias renováveis, contribuindo para a
descarbonização das economias e para uma maior qualidade de vida nos edifícios.
ABSTRACT: Energy efficiency and the decarbonization of the environment are topics that deserve growing concern from research centers and national and international organizations. In this way, there is a concern in the energy rehabilitation of buildings and the study of improvement measures which main focus is to turn the building into an NZEB (Nearly Zero Energy Build ing). Decree-Laws issued by member states of the European Union have several objectives and provide methodologies for calculating energy performance, establishing minimum require ments for new buildings. This dissertation addresses the implementation of energy certification in a service build ing, applying the calculation methods to a case study. It is intended to raise improvement pro posals that contribute to the increase in energy performance and favor the reduction of energy consumption. Finally, it is intended to carry out the maintenance plan of the different systems present in the building, in order to extend their useful life. The purpose is to demonstrate that the rational use of energy measures proposed in the energy certificate contribute to increase energy efficiency and sustainability. These promote a reduction in energy consumption and consequently the reduction of greenhouse gas emissions. The evolution and increase in the level of demand for energy certification in Portugal contribute to limit the energy consumption at home and commercial and service buildings, by mainly encouraging the renovation of existing buildings, devoid of energy efficiency when compared to new buildings. It is extremely important to promote a higher level of thermal comfort, reduce energy deficiency and encourage consumption from renewable energies, contributing to the decarbon ization of economies and to a better quality of life in buildings.
