Abstract(s)
Desde a década de 80 tem-se vindo a constatar a inversão de tendências no modelo de crescimento urbano. Enquanto os centros urbanos sofrem um processo de abandono, de
envelhecimento demográfico e de perda da identidade social e cultural, assiste-se a um
aumento da ocupação e impermeabilização do solo rural, associado ao consumo inconsciente
de recursos naturais e energia, da expansão de infra-estruturas, enfim a um maior impacte
ambiental.
Face a tal problemática, propõe-se, com a presente dissertação, valorizar a salvaguarda
e recuperação do património edificado, não só pela preservação da nossa identidade e da
nossa memória colectiva, mas também como meio de combate às actuais atitudes de
dinâmicas da dispersão e fragmentação urbana e aos problemas que daí advêm.
Sendo a Permacultura um instrumento de planeamento cujos princípios, agregados a
conhecimentos tradicionais e métodos construtivos de baixo impacto ambiental, são capazes de satisfazer as necessidades básicas do ser humano sem a degradação do ambiente apresenta-se uma proposta de reabilitação de um imóvel inserido no centro histórico da Guarda que, através do planeamento e posicionamento eficiente das energias naturais que entram no sistema (sol, vento, chuva, luz, fluxo da água), da vegetação envolvente, como controlo do microclima, e das práticas construtivas, onde deve prevalecer o bom senso, pretende demonstrar o alcance de um elevado grau de sustentabilidade e de auto-suficiência.
Esta dissertação permitiu concluir que é possível o uso da Permacultura como ferramenta ecológica para alcançar o planeamento sustentável, uma vez que com sua aplicação se pode reduzir significativamente os impactos causados além de possibilitar a regeneração de ambientes já degradados.
Since the 80’s we’ve been noticing that the model of urban growth has been suffering an inversion. While urban centers are facing an abandonment process, demographic aging and the loss of its social and cultural identity, we see that there’s an increase of the occupation and waterproofing of the agriculture ground, that associated to the unconscious use of the natural resources and energy and the expansion of infra structures, provokes a bigger environmental impact. Regarding this situation, it’s propose with this dissertation, enhance the protection and restoration of built heritage, not only to preserve our identity and our collective memory, but also as a means of combating the dynamics of the current attitudes of urban dispersion and fragmentation together with the problems that it brings. The permaculture is here applied as a planning tool whose principles, aggregate to the knowledge and traditional construction methods with low environmental impact, are able to meet the basic needs of human beings without degrading the environment. Thus, it is presented a proposition for the rehabilitation of a building in the historical center of Guarda. This proposition taking into account an efficient planning and natural energy (sun, wind, rain, light, water flow) of the surrounding vegetation and building practices to reach a high level of sustainability and self-sufficiency. This dissertation concludes that it is possible to use the permaculture as an ecological tool to reach a sustainable building rehabilitation.
