Abstract(s)
O presente relatório foi desenvolvido no âmbito do estágio curricular realizado na empresa
ASL & Associados, com uma duração de 6 meses. O desenvolvimento deste trabalho tem como
objetivo um primeiro estudo sobre as alterações que o DL 118/2013 sofreu a partir de 1 de
Janeiro de 2016, contextualizando com a certificação energética de edifícios de habitação
existentes (REH), uma vez que foi o trabalho desenvolvido ao longo do estágio curricular.
Inicialmente foi analisada a legislação em vigor referente ao comportamento térmico dos
edifícios em Portugal (gerido pela agência para a energia - Adene), para posteriormente ser
estudada e resumida, com vista a sua utilização e concretização do caso de estudo.
Após realizada a introdução legislativa, assim como a apresentação do tema, da estrutura do
relatório, das atividades desenvolvidas no estágio e da empresa na qual foi realizado o estágio
(ASL & Associados), foi necessário considerando relevante aplicar a metodologia e exigências
regulamentares a um caso de estudo, que serviu de base para comprovar a nível prático o
impacto a nível energético causado pelas alterações que o DL 118/2013 sofreu. Desta forma,
foi analisado um edifício de 4 pisos e 4 frações autónomas recentemente reabilitado, sito na
Rua D. João IV, Porto, sendo que apenas foram apresentados pormenorizadamente os valores
e parâmetros relativos a uma única fração, efetuando-se comparações do desempenho
energético antes e após a reabilitação com exigências prescritas nos documentos legislativos
em vigor até final de 2015 e os atuais (2016).
Por fim, através da análise dos indicadores de desempenho energético, foi determinado o
impacto que as alterações legislativas vieram causar, ao nível da necessidade de aumentar
isolamentos de forma a cumprir os limites regulamentares e do custo global anual de energia
que se reduz em comparação com a anterior regulamentação, para que no fim se realize um
balanço e uma análise crítica, assente nas comparações realizadas no caso de estudo
desenvolvido.
This report was developed under the traineeship held at ASL & Associates company, with a duration of 6 months. The development of this work aims a first study on the changes to the DL 118/2013 suffered from 1 January 2016, contextualizing with the energy certification of existing residential buildings (REH), since it was the work throughout the traineeship. Initially, it analyzed the legislation in force, regarding the thermal performance of buildings in Portugal (managed by the agency for energy - ADENE), later to be studied and summarized, with a view to their use and implementation of the case study. After making the legislative introduction, as well as the presentation of the subject, the report's structure, activities on stage and the company in which it held the stage (ASL & Associates), it was necessary considering relevant apply the methodology and regulatory requirements to a case study, which served as the basis to prove the practical level the impact the energy level caused by the changes to the DL 118/2013 suffered. Thus, a building of 4 floors and 4 units, located at street D. João IV, Porto, was analyzed and only been presented in detail the values and parameters for a single fraction, making up comparisons of energy performance before and after rehabilitation with requirements prescribed in legislative documents in force until the end of 2015 and the present (2016). Finally, by analyzing the energy performance indicators, it determined the impact of legislative changes came cause, the level of need to increase insulation in order to meet the regulatory limits and the overall annual energy cost is reduced compared to the previous rules, so in order to perform an assessment and critical analysis, based on comparisons made in the case study developed.
