Abstract(s)
O presente relatório de estágio vem apresentar um estudo, que tem como objetivo compreender as
alterações ao nível da eficiência energética e acústica de um conjunto de edifícios sitos em Bragança, alvo
de uma intervenção de reabilitação. Estes edifícios são fruto de um projeto de caráter social tendo sido
construídos na década de 80 e apresentam soluções construtivas típicas da época, pese embora se notem
alguns cuidados na escolha de materiais, devido às exigências climáticas da região em questão.
Neste estudo pretendeu-se compreender em que medida as soluções adotadas para a execução da
reabilitação contribuíram para uma melhoria da eficiência energética e acústica das habitações alvo da
empreitada de reabilitação. Essa melhoria foi quantificada seguindo as metodologias do Regulamento de
Desempenho Energético dos Edifícios de Habitação (REH) e o Regulamento dos Requisitos Acústicos em
Edifícios (RRAE).
Em complemento da análise das soluções construtivas adotadas, foram estudadas outras medidas por
forma a ser possível compreender quais as soluções que permitiriam atingir uma melhoria do grau de
eficiência das habitações, nos seus desempenhos térmico e acústico, e quais os consequentes encargos
monetários necessários.
Como produto destas análises, para que melhor se possa compreender qual o real impacto destas
intervenções, é ainda apresentado um estudo económico que relaciona o investimento necessário com o
retorno que este trará na redução da fatura energética
This internship report is to present a study that aims to understand the changes of energy efficiency and acoustics of set of buildings nestled in Bragança that were the subject of rehabilitation intervention. These buildings are the result f a social character of the project has been built in the 80s and present typical construction solutions of the time although it noted some care in choosing materials, due to the demands of the region concerned- In this study we sought to understand how the solutions adopted for the rehabilitation contributed to an improvement in energy and acoustic efficiency of the buildings that were intervened. This improvement was quantified according of the methodology of the “Regulamento de Desempenho Energético dos Edifícios de Habitação (REH)”, the Portuguese regulation of Energy Performance for Residential Buildings and the “Regulamento dos Requisitos Acústicos em Edifícios (RRAE), the Portuguese regulation of acoustical Noise for Buildings. In addition to the analysis of constructive solutions that make part of the real rehabilitation were studied other ways of comparative character in order to understand which solutions that help us to Achieve an improvement in efficiency of housing in their thermal and acoustic performances and how expensive it could be. As a product of these analyses and to better understand the real impact of these interventions, is also presented an economic study that relates the necessary investment with the return that it will bring in reducing the energy bill.
