Abstract(s)
A procura da ‘’Utilização Racional de Energia’’ de forma a diminuir a dependência energética
nacional impõe condutas a seguir na construção e utilização dos edifícios. Sendo o edificado
existente grande parte do parque imobiliário, resulta numa preocupação acrescida devido aos
seus baixos níveis de desempenho, impondo desafios ao nível da reabilitação energética,
desde o diagnóstico às propostas de melhoria que são exigidas pela regulamentação e pelas
necessidades de reduzir os consumos.
Esta dissertação integra matéria sobre os requisitos regulamentares impostos pelo
Regulamento de Desempenho Energético dos Edifícios de Habitação (REH) e a especificidade
da certificação energética de edifícios existentes, passando por um enquadramento da
temática e influência dos consumos energéticos. A principal metodologia de trabalho consistiu
na realização de quatro casos de estudo que, para além de serem guias de trabalho,
permitiram definir estratégias e procedimentos que podem resultar numa otimização da
abordagem a assumir num diagnóstico e na definição de estratégias de intervenção.
Com todo o interesse e riqueza contextual, o desenrolar da dissertação permitiu retirar
considerações finais fundamentais que promovem a sensibilização da população em geral com
medidas justificadas face à facilidade de compreensão e, de forma mais técnica são retiradas
conclusões impostas pelo desafio de propor melhorias na edificação existente de acordo com
as possibilidades da sua concretização.
The research about the Rational Use of Energy in order to reduce national energy dependency requires to follow certain procedures in the construction and use of buildings. Since the housing stock is mainly composed of existing buildings, there are concerns about their low levels of performance, imposing challenges in terms of energy rehabilitation from diagnosis to improvement proposals that are required by the regulations and needs to reduce the consumptions. This work integrates the regulatory requirements imposed by Regulation of Energy Performance of Residential Buildings (REH) and the specificity energy certification's of existing buildings, revealing a framework about the energy consumption and its influence. The main work methodology consisted of four case studies, which in addition of being work guidelines allowed to define strategies and procedures that can result in an optimization approach to take in a diagnosis and the definition of intervention strategies. With all the interest and contextual richness, the development of this thesis allowed to withdraw fundamental closing remarks that promote awareness of the general population and, technically, to draw conclusions about the challenge of proposing improvements in existing buildings according to their possibilities of implementation.
