Earth building. models, technical aspects, tests and environmental evaluation

Earth building is an ancient construction method, rarely in use in contemporary architecture. In skyscrapers, apartment blocks and other typical high constructions, reinforced concrete, metal and many other conventional materials are used in order for them to be build.  
 
But the same methods and the same materials are in use for small-scale buildings, while  it is not necessary to built with concrete or metal.  
 
In order to evaluate earth building, a comparison between a prototype model and a typical construction is presented in this paper, in terms of technical aspects and environmental evaluation.  
 
Models of suggested constructions in scale 1:20 are presented.
