The reduction of the energy consumption and carbon emissions in the building sector is an important target for actions to mitigate the climate changes and different actions are being carried out to promote a transition to a low carbon built environment. However, present standards are mainly focused on new buildings which may result counter-producti...
Many regulations and initiatives to promote the reduction of energy consumption and carbon emissions have been implemented in the building sector. However, they are mostly targeted at new buildings. In order to reach the goals that are being established, while it is necessary to implement measures in new buildings, this is doubly the case for exist...
The renovation of the existing building stock represents a huge potential in actions to mitigate climate change, not only by the improvement of the overall energy performance of the built environment, but also by the reduction of resource depletion and minimization of waste production
related with new construction. Nevertheless, this potential hasn...
In Europe, the latest updates in the directive on the energy performance of buildings introduced two fundamental concepts, namely the cost-optimal energy requirements and the nearly-zero energy buildings (nZEB). Although these concepts are related, the cost-optimal is focused on costs while the nZEB prioritise the energy performance and the use of...
The relevance of the building sector in the global energy use as well as in the global carbon emissions makes the improvement of the overall energy performance of existing buildings an important part of the actions to mitigate climate changes. Regardless of this potential, large scale building renovation has been found hard to trigger, with present...
Many regulations and initiatives to promote the reduction of the energy consumption and carbon emissions have been implemented in the building sector. However, they are mostly targeted for new buildings. In order to have an effective impact and reach the goals that are being established, it is necessary to act in new but especially in the existing...
A revisão da diretiva europeia relativa ao desempenho energético dos edifícios (EPBD recast), publicada em 19 de maio de 2010, introduziu a obrigatoriedade de todas as novas construções a erigir após 31 de dezembro de 2020 serem edifícios de necessidades quase nulas de energia (nZEB). Devem ainda todos os Estados Membros preparar planos que permita...
Following the impact of the climate changes and their causes, buildings proved to be one of the main responsible for the greenhouse effect due to the carbon emissions related with their construction and use. The recent changes in the European regulations, in a tentative to improve buildings energy performance, are mostly suited to new buildings. Ho...
Construction sector is one of the major responsible for energy consumption and carbon emissions and renovation of existing buildings plays an important role in the actions to mitigate climate changes. Present work is based on the methodology developed in IEA Annex 56, allowing identifying cost optimal and cost effective renovation scenarios improvi...
A urbanização de Vila d’Este é uma das mais importantes urbanizações de “habitação de custos controlados” em Portugal, com um total de 109 edifícios, alojando cerca de 17 mil habitantes. Tendo por base o processo de reabilitação em curso, é realizada uma análise de custos de ciclo de vida. O objetivo é identificar os níveis ótimos de rentabilidade...
A produção e consumo dos vários tipos de energia são dos grandes responsáveis pelas emissões de gases com efeito de estufa que contribuem para as alterações climáticas. No sentido de reduzir as emissões tendo em vista a mitigação das alterações climáticas, o setor dos edifícios, enquanto um dos grandes consumidores de energia, é um alvo de interven...
Cost optimality and nearly-zero energy buildings are two fundamental concepts within the current European Union policy related to the energy performance of buildings and consequently related to climate change mitigation and non-renewable resources consumption. While cost optimality is mainly focused on costs, nearly-zero energy buildings are focuse...
The recast of the European Union’s Energy Performance of Buildings Directive introduced the concept of nearly zero energy buildings, requiring its adoption from 2021 by all new buildings and existing ones submitted to major renovations. European Union member states must also ensure minimum energy requirements for buildings in order to achieve cost-...
The European roadmap towards a competitive low carbon economy in 2050 raised the awareness about buildings energy performance due to their potential for cost-effective energy consumption and carbon emissions reductions. For the evaluation of the levels of energy performance of buildings, the European Commission presented the Cost Optimal Methodolog...
Promoting the improvement of the overall energy performance of buildings is a relevant part of the European climate action and the Roadmap for moving towards a competitive low carbon economy in 2050, with an expectation of reducing greenhouse gas (GHG) emissions by around 90% when compared to 1990 values, in the area of the built environment. The r...
