Traditional buildings basically include natural and autochthonous construction materials and are built with sustainable construction techniques. The knowledge of these materials’s state and construction techniques is required for a proper conservation/renovation work. It is well known that the lack of maintenance is one of the main causes that contribute to the high degree of degradation that the Portuguese tra...

Em Portugal, a indústria de construção habitacional tem recorrido essencialmente às estruturas de betão armado e de alvenaria de tijolo cerâmico. As estruturas metálicas, de madeira e de alvenaria de pedra têm tido expressão reduzida nesse setor da construção, e são muito pontuais as aplicações da terra crua como solução construtiva. Nesse contexto, pretende-se estudar soluções construtivas mais sustentáveis, r...
Two alternative and highly sustainable building techniques are presented and described. The techniques are sugar reinforcement of earth based material and corncob based thermal isolation material. Some experimental results highlight the advantages and disadvantages of these two proposed techniques whose study is still beginning. The water resistance of earth based materials may be increased by adding a certain ...
Many of the existing buildings constructed mostly with natural raw materials, in European sites, are frequently lacking proper maintenance and, there-fore, a high degree of degradation is verified in these buildings compromising their integrity and reducing their lifetime probability. Often in the rehabilitation or reconstruction of old buildings the solution adopted is the partial or integral demo-lition and s...
Muitos dos edifícios construídos maioritariamente em materiais naturais, no espaço Europeu, revelam falta de manutenção adequada e apresentam por isso um elevado estado de degradação, comprometendo assim a sua integridade e reduzindo o período de vida útil do edifício. Uma das razões principais para este acontecimento é o custo da manutenção. É comum o aparecimento de patologias até em edifícios recentes. A cau...
In the last decades, the Portuguese housing building industry has been mainly fo-cused on the construction based on reinforced concrete framed structures and non-structural clay brick masonry for exterior and interior partition walls. Recently, this industry started to in-clude alternative structural materials, such as steel and timber. The earth based construction techniques and solutions still remains limited...

Em Portugal, a aplicação nas estruturas de materiais naturais ainda corresponde apenas a solução construtiva pontual. Neste contexto, foram estudadas duas soluções estruturais para uma habitação unifamiliar sendo uma de betão armado, denominada aqui por solução tradicional, e outra de alvenaria de adobe e pavimentos de madeira, denominada por solução sustentável. Avaliou-se o impacto ambiental associado à produ...
