Earth building
In the Bulgarian language the word “earth” means the planet on which we live as well as the top layer of this planet – the surface on which life develops. As the words clay (one of the constitutive elements of earth), kirpitch (word of Turkish origin –synonym of clay), daubed earth (a type of building technique, soil, ground … have a partial, incomplete meaning to cover the different building techniques, I use the term “earth building” to designate all the building techniques that use earth as a main building material. 

Ecological building
Holistic building approach that aims at improving the relationship between Man and the surrounding environment through:

– using  local and available building materials with a short production cycle that are easy to recycle;
– taking into account the local climate conditions and relief;
– taking into account the local culture, customs and traditions;
– optimized use of energies and energy sources for life necessities;
– optimized use of entering and exiting natural elements (water, air).

Sustainable building
Building that searches to optimize the use of materials, energies, natural elements (water, air) and to minimize the footprint of Man on the environment. This approach insists on technological solutions rather than the complete reconsideration of the role and place of Man in natural processes.

Bio-climatic building
Building that proposes an optimized comfort to the inhabitants through a rational use of the disposition of the building in relation with the geographic conditions, the movement of the sun, material’s properties (insulation, inertia, reverberation…), as well as the natural elements (air, water).
