Research on the Portuguese building stock and its impacts on energy consumption...
Sousa, J. Bastos; Bragança, L.; Almeida, Manuela Guedes de; Silva, Pedro Correia Pereira daThe article aims to evaluate the Portuguese building stock energy policies and strategy for energy saving in buildings among the EU members. It was found out the average heat transfer coefficients of the main structural elements of Portuguese Buildings and analyzed the U-values of this elements considering different time periods. The fundamentals of this study were funded by the Agency for Development and Innov...
IAQ analysis of Portuguese residential buildings
Silva, Sandra Monteiro; Silva, Pedro Correia Pereira da; Almeida, Manuela Guedes de; Bragança, L.In average, man spends about 90% of the time inside enclosed spaces, in both residential and office buildings, exposed to consistently higher concentrations of air pollutants than outdoors, which has led to the increased rate of allergies and asthma incidences. In the last decade, public and governmental awareness on indoor air quality (IAQ) has been growing. Portugal implemented the National Building Energy an...
Improving buildings refurbishment through operative conditions evaluation
Silva, Sandra Monteiro; Silva, Pedro Correia Pereira da; Almeida, Manuela Guedes de; Bragança, L.As EU existing buildings stock account for 40% of the total energy consumption, it is important to take measures to reduce these needs and, consequently, reduce the EU external energy dependency as well as reducing the greenhouse gas emissions, in accordance with what is prescribed in the EU Directive 2002/91/EU on Energy Efficiency in Buildings (EPBD) and reinforced with the "EPBD-recast". The implementation o...
Definition of the energy performance requirements in rehabilitation projects
Almeida, Manuela Guedes de; Silva, Pedro Correia Pereira da; Silva, Sandra Monteiro; Bragança, L.Building rehabilitation is essential to achieve the targets defined by the EPBD-recast regarding energy efficiency, reduction of carbon emissions and use of on-site renewable energy sources. To propose an effective building rehabilitation it is necessary to study the best combination of available options in terms of construction solutions, technical building systems (hot water, ventilation, heating, cooling an...
Módulo inovador para a reabilitação energética
Silva, Pedro Correia Pereira da; Almeida, Manuela Guedes de; Bragança, L.; Mesquita, VascoA reabilitação energética dos edifícios é uma área com crescente importância para o setor da construção Portuguesa. Tal deve-se a uma conjugação de diversos fatores, desde o estado de degradação e fraco desempenho energético dos mesmos, até à drástica redução do índice de construção nova. Como tal, de modo a adequar o parque habitacional existente às novas necessidades, mas também às mais recentes exigências po...
Retrofit module design guide : part D : prefabricated metal panel retrofit modules
Silva, Pedro Correia Pereira da; Almeida, Manuela Guedes deInternational Energy Agency The International Energy Agency (IEA) was established in 1974 within the framework of the Organisation for Economic Co-operation and Development (OECD) to implement an international energy programme. A basic aim of the IEA is to foster co-operation among the twenty-eight IEA participating countries and to increase energy security through energy conservation, development of alternativ...

Metodologia de simulação com vista à reabilitação energicamente eficiente
Silva, Pedro Correia Pereira da; Almeida, Manuela Guedes de; Bragança, L.; Mesquita, VascoO parque habitacional é um dos sectores de intervenção prioritária, tendo em conta que estes representam 40% do consumo de energia final na Europa. Com a entrada em vigor da Directiva Europeia da Performance Energética de Edifícios (EPBD), foi dado o primeiro passo neste sentido, introduzindo-se diversas medidas que limitam o consumo de energia primária nos edifícios. Com a aplicação desta Directiva, a discrep...
Portuguese building stock indoor environmental quality “in-situ” assessment
Silva, Pedro Correia Pereira da; Silva, Sandra Monteiro; Almeida, Manuela Guedes de; Bragança, L.; Mesquita, VascoSince the implementation of the Energy Performance of Building Directive, EPBD, in general, and the entrance into force of the respective Portuguese codes, in particular, buildings are requested to have better energy performances. However, during the buildings performance evaluation, energy issues should not be the only concerns since the indoor environmental quality is also as important. Thus, in this paper it...
Laminados de CFRP pós-tensionados no reforço à flexão de lajes de betão armado ...
Barros, Joaquim A. O.; Lourenço, Lúcio; Silva, Pedro Correia Pereira da; Rosado, MárioNeste trabalho são descritos os principais procedimentos de dimensionamento e de aplicação de um sistema de reforço baseado em laminados pós-tensionados em laje vigada de pavimento de betão armado que apresentava deformabilidade excessiva e resistência à flexão deficiente.
