Deterioration of the granitic stone at Misericórdia chapel in Murça (northern P...
Alves, Carlos; Vasconcelos, Graça; Fernandes, F. M.; Silva, Sandra MonteiroIn this work are considered the main deterioration processes of the granitic stone at the Misericórdia chapel of Murça (Vila Real). In the main façade and indoors there are erosive features (that can endanger decorative elements) and salt efflorescences with distributions that suggested the influence of capillary rising solutions, hypothesis supported by studies with ground penetrating radar and thermography. T...
Avaliação em laboratório do comportamento térmico de soluções construtivas em m...
Oliveira, Marco A.; Silva, Sandra Monteiro; Branco, Jorge M.; Bragança, L.; Lourenço, Paulo B.O presente trabalho apresenta a avaliação do comportamento térmico de quatro soluções construtivas integralmente em madeira, recorrendo à previsão e análise experimental do seu desempenho térmico. Foram avaliadas quatro soluções construtivas representativas do mercado, três delas tendo por base troncos de madeira e uma outra do tipo entramado de madeira. As principais tipologias de habitações que se encontram n...
Using PCM to improve building's thermal performance
Silva, Sandra Monteiro; Almeida, Manuela Guedes deDue to EU and worldwide high energy consumption of the buildings stock, it is important to take measures to reduce these needs and, consequently, reduce the EU energy dependency as well as the greenhouse gas emissions. To improve the behaviour of the buildings, concerning thermal comfort of the occupants and energy performance, it is necessary to reduce the thermal amplitudes, the winter heat losses, the summer...
Assessment of the bond quality degradation in FRP-strengthened masonry using IR...
Ghiassi, Bahman; Silva, Sandra Monteiro; Oliveira, Daniel V.; Lourenço, Paulo B.; Bragança, L.The FRP-to-masonry bond behavior in externally bonded reinforced masonry structures is the main mechanism in controlling the effectiveness of this technique. Therefore, monitoring the quality of bond during the service life of the structure is of crucial importance for structural health evaluation. The bond quality may be affected due to environmental conditions which results in local detachments at the FRP/sub...
Selection of refurbishment construction solutions to improve the indoor environ...
Silva, Sandra Monteiro; Almeida, Manuela Guedes deBuilding 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. Besides the energy efficiency the Indoor Environmental Quality of Buildings (IEQ) and environmental impact must also be considered when planning a refurbishment project. Thus to propose an effective building rehabilitation ...
Using MCDA to select refurbishment solutions to improve buildings IEQ
Silva, Sandra Monteiro; Almeida, Manuela Guedes deDue to buildings high energy consumption their refurbishment is essential to achieve the targets defined by the EPBD-recast regarding energy efficiency and reduction of carbon emissions. Besides the energy efficiency, the sustainability and the Indoor Environmental Quality (IEQ) of Buildings must also be considered when planning a refurbishment project. Thus, to propose an effective building refurbishment it is...
Potentialities of using PCM in residential buildings in Portugal
Mustaparta, Olli; Silva, Sandra Monteiro; Leitão, DinisIn the past few years the energy crisis has been a big topic around the world and many studies have been made to improve the efficiency of energy use. One of the research areas is the building sector and his heating and cooling systems. Constantly changing weather has a large effect on room temperatures and thermal comfort of residents. Controlling devices and appliances are consuming a large amount of energy t...
Optimization of the sustainability during the refurbishment operation of a resi...
Mateus, Isabel; Mateus, Ricardo; Silva, Sandra MonteiroMost of the existing buildings have high resources consumption and low indoor environmental quality, leading to the unsustainability of the built environment. Being aware of this reality and based in the European goal to achieve Nearly-Zero Energy consumption standard in buildings, it is urgent to define guidelines that could support the sustainable refurbishment design since the earlier stages. This paper inte...
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...
