WHY HAVE COME INTO THE LIMELIGHT THE EARTH ARCHITECTURE?

During the history of humanity developed rightly an idea about, that the raw materials and energy sources, which are the basis of economy, are boundless and for this reason they are available for free or for very low prize. Of course we could rightly think this way as long as we only used reproducing energy sources and raw materials, which were mostly used in reproducing amounts. But in the 1960's and 70 ' independent organisations (Roman Club) than in the 80' government organisations (Bruntland Committee) and in the 90 ' inter-governmental organisations (Rio de Janeiro: Agenda 21) realised that using of energy and raw materials, and changing the environment in the present form of the human life is not sustainable in long term. [1] More and more begin to think that in the future at several parts of life next to questions like "Is it worth? " or "Is it nice? " we have to answer a new fundamental question: "Is it sustainable in long term?" The question of the more and more often mentioned "Sustainability " raised new point of views and requirements at the relation in building materials as well. Some architects and builders realising the ecological, building-physical advantages of the earth building overvalued the traditional preconceptions about the earth architecture, and next to the rebuilding of ancient earth houses built with traditional technology, started to think of the modernisation and alternative adoption of earth architecture. (Explaining this not fully developed terminology, the term "earth building " I mean the traditional mud walls, straw clay walls and houses made out of adobe, and varies of some further developed technologies were the local building materials is used after dried on the sun, without being burnt.
