Roof replacement of a heritage building using transparent solutions: room acous...
Macieira, Mónica Raquel Fernandes; Mendonça, Paulo; Guedes, João Miranda; Carvalho, António P. O.Tensile membrane roofs are considered to have the potential to improve the buildings’ performance due to their lightweight and flexible nature. However, their potential for improving acoustic behaviour has hardly been accurately gauged or demonstrated due to their complexity in both geometric and physical aspects. To address this issue, Carmo’s church in Lisbon—a heritage building that lost the roof during the ...
Bituminous waterproofing mortar applied on masonry walls of 19th and 20th centu...
Lier-Klüge, Andreia; Vieira, Eduarda; Guedes, João Miranda; Ferreira, Cláudia; Frade, José Carlos; Bordalo, RuiBituminous mortars characterize the traditional buildings of the city of Porto and northern Portugal, especially those built between the end of the 19th century and the first decades of the 20th century. This article aims to determine the composition of this bituminous mortar through an analytical study by micro-FTIR and Py-GS/MS, and to assert experimentally its effectiveness as a waterproofing material though...

Energy performance of vertical extensions on old buildings: comparison between ...
Mendonça, Paulo; Macieira, Mónica Raquel Fernandes; Guedes, João MirandaThis research aims evaluating in what measure the proposed refurbishment solutions with architectural membranes can benefit an existing building and provide an energy efficient alternative to conventional reference building technologies for vertical extensions. In order to do it, an old building from the 19th century, located in Porto (Portugal) is taken as case study. Both solutions are compared regarding ther...
Membrane sunspace for old buildings refurbishment: environmental impact, econom...
Macieira, Mónica Raquel Fernandes; Mendonça, Paulo; Guedes, João MirandaThis study presents a state of the art and design proposal for membrane sunspaces, as alternative to conventional ones, in glass, commonly used in the functional refurbishment of old buildings. Sunspaces are passive solar systems that can be easily integrated in existing buildings. Enclosing balconies with glazing has an impact on existing building functional performance (useful area, thermal performance and ac...
Overview of constructions made with architectural membranes: market, geographic...
Macieira, Mónica; Mendonça, Paulo; Guedes, João MirandaWith the growing concern about material savings and climate change, it is important to analyse how membranes have been applied to constructions over time according to geographic location and type of use. There are many requirements associated with membrane building technologies and structures, though, currently, there is no membrane in the market that fully meets all requirements. In this way, the criteria to u...
Membrane for rooftop extensions: an economical and environmentally efficient al...
Macieira, Mónica Raquel Fernandes; Mendonça, Paulo; Guedes, João MirandaAlternative solutions must be studied when the costs and weight of the constructive solution are inhibiting factors (for owners, designers, investors and different parties involved). The increasing importance given today to the environmental compatibility leads designers to combine both the use of energy efficient materials and technical solutions to maximize savings. Membrane building technologies are interest...
Reabilitação funcional do património industrial edificado com recurso a membran...
Macieira, Mónica Raquel Fernandes; Mendonça, Paulo; Guedes, João MirandaNo âmbito da utilização de membranas arquitetónicas na reabilitação funcional de edifícios, destacam-se as intervenções sobre o património industrial. No presente estudo são analisados 9 projetos representativos deste tipo de intervenções, de acordo com parâmetros contextuais, climaticos e funcionais. Os resultados desta análise realçam o desempenho adequado das membranas arquitetónicas, em particular das estra...

Macieira, Mónica Raquel Fernandes; Mendonça, Paulo; Guedes, João MirandaIn the research framework of the use of architectural membranes on functional buildings rehabilitation, stands out interventions on industrial heritage. In this study 9 representative projects of this intervention’s type are analyzed, according with programmatic, constructive and economic parameters. It was found that most of these buildings are located in Europe and were converted into cultural or office activ...
Correlação entre ensaios com câmara termográfica e resistógrafo na avaliação da...
Pinto, Jorge; Teixeira, Marcos D. E.; Cunha, Vitor M. C. F.; Arede, António; Guedes, João Miranda; Cunha, Sandra Raquel Leite; Feio, A.; Varum, HumbertoEste trabalho de investigação pretende dar um contributo no campo das técnicas não destrutivas de inspecção e de diagnóstico de vigas antigas de madeira. Para o efeito, correlacionou-se os resultados obtidos através do uso do resistógrafo e da termografia no estudo de uma viga recolhida num edifício de habitação unifamiliar que foi sujeito a um processo de remodelação. Verificou-se que poderá haver uma cerca co...
