The traditional architecture is founded as a defining element of the identity of a region, and its essence should be preserved and conserved by means of maintenance and recovery actions. Thus, the best solutions and proposals for intervention should be looked for but this doesn’t imply a back to back innovation and at construction progress. This work includes the description of techniques for maintenance and conservation of bioclimatic solutions found and inventoried in the north of the Iberian Peninsula, with special focus on a unique bioclimatic solution known as Sunspace, whose main advantage is to contribute significantly to the improvement of the thermal performance of buildings. It is also important to recover the historical heritage in a sustainable manner, allowing it to become an engine of development for both urban and small rural centres that exist in the periphery of the bigger cities.

Thus, the best solutions and proposals for intervention should be looked for but this doesn’t imply a back to back innovation and at construction progress. This work includes the description of techniques for maintenance and conservation of bioclimatic solutions found and inventoried in the north of the Iberian Peninsula, with special focus on a unique bioclimatic solution known as Transition Spaces (from the interior to the exterior of the buildings and vice-versa), whose main purpose is to ensure protection from the elements when entering or exiting buildings, to contribute to the improvement of the buildings thermal performance and to create sheltered interior/exterior living spaces. This architectural characteristic is based on the building’s solar exposure, predominant winds and geographical and topographic conditions. It is important to recover the historical heritage in a sustainable manner, allowing it to become an engine of development for both urban and small rural centres that exist in the periphery of the bigger cities.

Não é possível fazer uma avaliação do patrimônio histórico somente por meio de valores estéticos; o desenho e os símbolos da cidade também se tornam memória na medida em que adquirem uma dimensão coletiva: é necessário considerar a importância da edificação como característica de um processo de reconhecimento do lugar e não da capacidade do seu autor. A cidade resulta das relações que cada elemento estabelece com todos os outros, da existência de traçados históricos e de edificações capazes de manter e traduzir a memória histórica do lugar, também e principalmente com aqueles espaços imateriais, como os vazios urbanos, ou com edifícios industriais, pois eles marcam o território. Técnicas de expansão urbana foram substituídas na Europa por práticas de recuperação e remodelação fundamentadas na história, por meio de significados coletivos, intrínsecos e estratificados, ou seja, baseados nas tradições regionais e pertencentes à cultura popular. Esta se manifesta de modo muito diferente em cada região, em função de suas raízes, costumes e identidade. Para exemplificar esse fenômeno, foram selecionadas duas situações de recuperação arquitetônica em Milão que se desenvolvem em duas escalas de interferência urbana diferentes...

Esta tese possui como perspectiva de análise as manifestações contemporâneas de produção das arquiteturas vernáculas e culturas construtivas, dentro da complexa correlação de forças e interesses que formatam e determinam os fenômenos de produção capitalista das habitações populares. Seu contorno analítico está delineado a partir de uma série de reflexões de ordem teórico-conceituais relacionadas com as análises de um canteiro habitacional dentro de um assentamento rural de reforma agrária. Este, assume a forma de um Canteiro-Escola e se projeta como palco de experimentações e vivências, onde se propõe como prática o exercício de conjugar pedagogia e produção no mesmo espaço. Os processos de formação e construção dos conhecimentos ocorrem de maneira complementar e simultânea às realizações práticas e ao desenvolvimento das tecnologias. O canteiro se transforma, assim, em ferramenta para constituição de um espaço dialético de trabalho social, onde o experimentar produtivo está focado no desafio de conceber uma habitação a partir da geração local de tecnologias sociais, por meio do uso de materiais naturais e da reutilização de recursos descartados. O trabalho teórico, apresentado nas primeiras partes da tese...

quot;Tradition is not necessarily old-fashioned and is not synonymous with stagnation. Furthermore, a tradition need not date from long ago but may have begun quite recently. Hassan Fathy. Tradition consists in the repetition of a gesture that, due to its symbolic significance, existing resources or proven quality as a solution to a problem, has become relevant and ensures its permanence in time. Evolving from different origins and periods, each new tradition adds on to all its predecessors and contemporaries, resulting in a palimpsest, in the accumulation and depuration of transferred knowledge, into renewed traditions.From the quot;indigenousquot; to the endogenous. Within the colonial context, the discussion over the status of the quot;nativesquot; has come a long way to reach a recognition of dignity, specificity and endogenous knowledge. Although the Portuguese overseas policy might have been more permeable to existing communities in colonized territories than other colonial powers, and though successive restructuring and strategic changes in its ideology might have contributed to a progressive self-determination, the conditions for genuine emancipation were only met with the independence of the new nations. In this context of definition and construction of a collective identity...

Vernacular architecture is characterized by formally expressing several constraints – geographical, climatic and economic – from the places where it is. In its plurality, it manifests several constraints from places and communities who built and inhabit them. Those constraints are reflected in regional differentiation of the strategies used to mitigate the climate effects. Portugal, despite the small size of the country, is profuse in these manifestations of architecture. The strategies adopted in these buildings have potential to evolve and to be adapted to contemporaneity. Future should seek to integrate tradition and modernity, in order to explore new aesthetics and functional buildings. In this sense, Portuguese vernacular architecture has a knowledge that matters to be studied and classified from a sustainability point of view. When world seeks for cleaner energy and more sustainable buildings, it is pertinent to revisit the past in order to understand these forms of construction intrinsic to places, shaped over the time to deal with scarce resources.

Dissertação de mestrado em Construção e Reabilitação Sustentáveis; The vernacular architecture features, in a particular way, a plurality of constraints — geographical, geological, economical and cultural — from the places where it is. The constraints of each region were materialized in unique and diverse ways of building between them. In common they have the fact that they were parsimonious evolutions, empirically refined over generations. In its long evolution, and inserted in a context of scarcity, tpeoplehey developed pragmatic strategies of adaptation to the environment and of profound rationalization of the available resources. Nothing was preferred, passed over or ignored because communities had the empiric notion that their welfare depended intrinsically from the balance with their surroundings. However, these architectural approaches were abandoned, and the inherent knowledge lost, driven by the pejorative connotations that relate it with underdevelopment, both in materials as in lifestyles. Industrialization homogenized the different ways to build and propelled the spread of a universal architecture, disconnected from its environment, heavily dependent on energy and resource consumption. In this sense, at the moment when society seeks for cleaner energy and more sustainable buildings...

Publicado em "Vernacular heritage and earthen architecture : contributions for sustainable development", ISBN 978-1-138-00083-4; Vernacular architecture embodies a plurality of constraints from places where it belongs, in which the use of local materials and techniques is one of the main features. When compared with industrially-produced materials, vernacular materials have low environmental impacts, being an alternative for sustainable construction. The increasing use of new industrially-produced and standardized materials led to the homog-enization of the different used construction approaches, and spawned a universal architecture that in many cases is out of the environment context and is very dependent on energy and other resources. This paper ad-dresses the relation between Portuguese vernacular architecture and locally sourced materials, relating them with the territory lithology, agricultural crops and the climate. To assess the contribution of these materials for sustainability, a comparison with industrial materials at level of environmental indicators was established. This paper highlights the advantages of using local materials and techniques as a factor of local socio-economic development.

The study focuses on the identification of a typology of vernacular architecture, characterized by dispersion and isolation on a territory usually associated with concentrated settlements. This paper aims to contribute for understanding how local factors (climate, economy, culture, etc.) influenced vernacular architecture in the northeast of Portugal by analysing the strategies and building solutions that enable it to cope with climatic adversities. Through in situ monitoring temperatures and relative humidity,is attempted to show the potential of the case studies in maintaining the indoor air temperatures within the boundaries of comfort even when the external temperatures are outside the boundaries.

The use of local materials and techniques is one of the main features from vernacular architecture. When compared with industrially-produced materials, vernacular materials have low environmental impacts, being an alternative for sustainable building. However, industrialization have brought new standardized materials that led to the homogenization of the different building approaches and spawned a universal architecture often with no context concerns and with significant environmental impacts. As for sustainability, vernacular materials have potential to evolve and to be adapted to contemporary needs, helping to reduce the embodied energy and environmental impacts. Therefore, this paper addresses potential advantages of using local materials and techniques in the Portuguese context. Moreover, this paper establishes a comparison between vernacular and industrially-produced at level of environmental indicators (embodied energy and global warming potencial).

For a long time, reactive seismic retrofitting was focused on monumental heritage and very little on vernacular architecture. In the last years, there has been a growing interest on seismic resistant design and solutions and several research units emerged to produce important research in the scientific field. However, for some time, international focus to address earthquake-damaged buildings was on intrusive techniques and technological materials to retrofit monuments. This paper aims to explore how the research project SEISMIC-V intends to fill the gap regarding this critical research problem. The research will contribute to the awareness and protection of the local seismic culture. The project outcomes will provide data for the strengthening of seismic-resistant architectural components in in-use vernacular heritage.; Fundação para a Ciência e a Tecnologia (FCT)

Specific architectural elements can be identified in vernacular constructions located in regions frequently exposed to earthquakes. Such elements are the result of a seismic culture which has been empirically developed during centuries so that the vulnerability of the buildings is reduced. This research is based on the fact that vernacular architecture may bear important lessons on hazard mitigation. Traditional earthquake resistant technologies can be successfully applied to preserve and retrofit surviving examples without prejudice for its identity. Few papers have focused on strengthening solutions emerging from vernacular architectural heritage. Research is particularly focused on case studies in Portugal where traces of Local Seismic Culture have been identified and documented through direct visual inspection, published information and local narratives. The main goal of this study is the identification and understanding of traditional construction solutions and detailing that, in many cases, have shown to improve the seismic performance of vernacular constructions.; Fundação para a Ciência e a Tecnologia (FCT)

Mediterranean vernacular architecture was developed not only with respect to environmental and climatic factors but also with respect to culture, traditional construction materials and morphology. Despite the far distance between Portugal and Egypt, it was possible to find similar vernacular strategies under the influence of the Mediterranean climate and both Roman and Arab cultures. The paper adopted an explanatory qualitative analysis and comparative synthesis methods for vernacular passive and climatic responsive strategies for two regions. Covering from site planning, building design till building materials used through considering topography, resources, historic and cultural aspects. The outcomes of this research allow for understanding how different passive solar strategies and the use of natural energy sources can contribute to achieve appropriate indoor comfort conditions for contemporary practice. The paper draws a set of recommendations for more in-depth quantitative survey and energy efficiency measurements in Mediterranean climate.

Vernacular architecture is characterised by a type of formal expression that has been developed in response to a number of factors â climatic, lithologic, cultural and economic â characterising the local area or region. In its various forms, a range of techniques has been employed in different regions to mitigate the effects of climate. Despite the fact that Portugal is a small country, it has a territory full of contrasts, which gave origin to many different architectural manifestations. The approaches adopted in the design and construction of vernacular buildings have the potential for further development and could be adapted in response to contemporary needs. In the future, a blend of tradition and modernity should be aimed at in order to develop a new form of aesthetics and functional construction. Portuguese vernacular architecture is associated with a fund of valuable knowledge that should be studied and aligned with the principles of sustainability. In this paper, is presented the climatic contrast between the northern and southern parts of Portugal and the relation with the purpose of different passive solar techniques used in vernacular architecture to provide comfort. The focus is on the effectiveness of passive cooling techniques (e.g. high thermal inertia...

Dissertação de mestrado integrado em Engenharia Civil; As crises energética e ambiental, com as quais a arquitetura e a construção contemporâneas se confrontam, fizeram aumentar, nos últimos anos, o interesse pelas estratégias de controlo natural e passivo das condições de conforto da arquitetura tradicional. A arquitetura vernácula apresenta técnicas construtivas simples, desenvolvidas de forma empírica ao longo de gerações, marcadas pela estreita relação com as condições locais do meio em que se insere (clima, recursos, cultura, etc.). Em Portugal, a arquitetura vernácula carece ainda de um vasto trabalho de campo que comprove cientificamente a veracidade das diversas estratégias e potencialidades deste tipo de arquitetura. Neste sentido, o presente trabalho tem como principal objetivo avaliar in-situ o comportamento e as condições de conforto de um edifício tradicional português, da região da Beira Alta. As principais estratégias passivas utilizadas na arquitetura vernacular beirã são as varandas envidraçadas. Os indicadores de conforto analisados foram o ambiente térmico, a iluminação e a qualidade do ar interior. A metodologia de ensaio baseou-se em trabalho campo composta por avaliações subjetivas do nível de conforto dos ocupantes e avaliações objetivas dos parâmetros físicos do edifício. Os parâmetros monitorizados foram a temperatura e a humidade relativa do ar...

Vernacular architecture is characterized by a type of formal expression, which has been developed in response to a number of factors – geographic, climatic and economic – characterizing the local area or region. Despite the fact that Portugal is a small country, there are many different architectural approaches and a range of techniques have been employed in different regions to mitigate the effects of climate. These vernacular approaches have the potential for further development and could be adapted in response to contemporary needs. In this paper, a range of different passive solar techniques used in Portuguese vernacular architecture to provide comfort is presented. The specific focus is on the effectiveness of passive cooling strategies (namely, high thermal inertia, use of light colours and courtyards), and the findings of a case study in which the thermal performance during the summer of a vernacular residential building located in the south of Portugal are presented.

Considering that vernacular architecture may bear important lessons on hazard mitigation and that well-constructed examples showing traditional seismic resistant features can present far less vulnerability than expected, this study aims at understanding the resisting mechanisms and seismic behavior of vernacular buildings through detailed finite element modeling and nonlinear static (pushover) analysis. This paper focuses specifically on a type of vernacular rammed earth constructions found in the Portuguese region of Alentejo. Several rammed earth constructions found in the region were selected and studied in terms of dimensions, architectural layout, structural solutions, construction materials and detailing and, as a result, a reference model was built, which intends to be a simplified representative example of these constructions, gathering the most common characteristics. Different parameters that may affect the seismic response of this type of vernacular constructions have been identified and a numerical parametric study was defined aiming at evaluating and quantifying their influence in the seismic behavior of this type of vernacular buildings. This paper is part of an ongoing research which includes the development of a simplified methodology for assessing the seismic vulnerability of vernacular buildings...
