Abitare la terra: la terra per abitare. Le tecniche costruttive tradizionali in terra cruda, fra conservazione, innovazione e restauro
The architectural heritage made of earth is widespread in different areas of the world. It has been studied enough, although without deepen the different local specificities, as it would be necessary for its wide diffusion. The theoretical reflection on its conservation, instead, has not reached, in all the countries, a level such as to avoid the systematic replacement of damaged original parts, with the definitive loss of original material. Starting from these premises, the aim is to highlight technological expedients, local variations and particularities (in areas with low or high seismic risk), deepening the knowledge of some regional realities, with particular attention to Sardinia, where earth constructions exist since the nuragic age and the continuous use from the Phoenician-Punic age until today.
The knowledge of technical devices, resulting from a millennial experience, is the basis for the correct conservation (restoration and consolidation) of what exists and for the design of new structures.
