A ocorrência de eventos sísmicos tem causado grandes perdas humanas e econômicas, como também elevados danos ao patrimônio cultural mundial. Diante disso, torna-se importante estudos que analisem o comportamento das obras de engenharia civil, e em especial modo das construções históricas, mediante a ocorrência de ações sísmicas. Neste trabalho serã...

... The global environmental awareness and the rising demand for environmentally friendly materials are pushing the sector to shift to the "sustainability" paradigm. Thus, the sector is slowly starting to adopt materials with lower embodied energy and other environmental impacts, and those that are more compatible, for instance, with the local climate context [59]. ...
Thesis
Vernacular architecture is characterised by embodying and expressing a plurality of factors - geographic, climatic, economic and cultural - of the places in which it is located. In its long evolution, and inserted in a context of scarcity, a range of pragmatic strategies and building techniques of adaptation to the surrounding environment were developed. These strategies/materials are usually simple, low-tech and have a low potential environmental impact. From a sustainability point of view, several studies highlight them as having the potential to reduce the environmental impacts of buildings. In Portugal, there are many expressions of vernacular architecture, whose specificities are an identity factor of several regions. However, there is a lack of quantitative studies on the thermal and environmental performance of vernacular buildings and materials in the Portuguese context. In this sense, this research work presents a qualitative and quantitative study of i) climate-responsive strategies; ii) the thermal performance and comfort conditions of different Portuguese vernacular buildings throughout the different seasons; and iii) the environmental performance of vernacular materials. The research focused on the study of three case studies, with specific features and located in three different zones of mainland Portugal. The thermal performance and comfort conditions of the case studies were evaluated through in situ monitoring of hygrothermal parameters, surveys on occupants’ thermal sensation, and the data analysed according to an adaptive model of comfort. To compare the influence of some strategies on the annual energy demand for heating and cooling, simulations under dynamic conditions for different scenarios were carried out. In the case of vernacular materials, although these are seen as ecological, the quantitative studies available are scarce and that allow establishing an equative comparison with conventional materials. Thus, the life cycle assessment of two earthen materials, rammed earth and compressed earth blocks (CEBs), was carried out and based on specific life cycle inventory values obtained from a producer company, following the guidance provided by the standard EN15804. From the results, in general, it was found that the case studies have shown a good thermal performance by passive means alone and that the occupants feel comfortable, except during winter when there was a need to use heating systems. In the case of materials, in a cradle-to-gate analysis of different walls, the use of earthen building elements can result in reducing the potential environmental impacts by about 50%, when compared to the use of conventional ones. Additionally, earthen materials have the advantage that they can be recycled/reused in a closed-loop approach.

The living building concept (Rosmaninho, 2012), arises by opposition to the modernist “machine for living in” (Le Corbusier, 1923). Other namesake concepts of living building (McLennan, 2005, Armstrong 2012) echo the importance of this biocentric metaphor in describing an architectural approach rooted in a new regenerative, symbiotic and holistic development and sustainability paradigm, which has in the Permaculture movement one of its finest examples. Studying the significance of this metaphor, we searched for its correspondence in the realms of Biology and Philosophy informing these ecologist design methods and their ethics. In this pursuit, we focus on a concept which might have a unique relevance for sustainability and even to understand Life itself and its architecture: the ecological niche as the living-building’s place. The Niche Construction Theory argues that ecological inheritance is a fundamental factor for biological evolution and that ecological niche construction is an epigenetic evolutionary process in its own right. If Humanity’s architecture is one of the best examples of the impact of this process in a specie’s evolution, it surely is crucial to understand how a better knowledge of this biologically universal process could capacitate ways of life which are ecologically adapted, culturally adequated and technologically efficient. Traditional ways of life find themselves also facing the challenges of this new paradigm. The Monastery of Our Lady of the Rosary, where the Monks of Bethlehem dwell, is located among the Alentejo and Ribatejo regions of Portugal, and conveys the experimental scenario where this process of eco-cultural niche construction shall unfold. Studying the pattern languages (Alexander, 1977) of the phenomenological ecology (Riegner, 1993) of the cork-oak montado forests, we try to conceive the micro-landscapes which might intertwine the vocation of this monastic community and its cloistered liturgy with this ecosystem’s patterns and the rural architectures implied in its existence.
