Nel tema della terra cruda spesso ricorre una sorta di dualismo tra passato e futuro: da un lato, il patrimonio architettonico in crudo costruito sin dall’antichità più remota costituisce un campo di indagine rilevante per il valore documentario e per gli specifici problemi di conservazione. Dall’altro, la terra cruda è posta come valida alternativa per le costruzioni di oggi, all’interno di una diffusa tendenza verso la sostenibilità. Tanto la necessità di conservare meglio le testimonianze del passato quanto l’istanza di gravare meno possibile sull’ambiente con nuovi edifici, portano ad una sola certezza: la centralità della conoscenza. Dopo decenni di studi, si può affermare che non manchino affatto le nozioni base sul materiale e sulle tecniche di impiego e si deve riconoscere piuttosto avanzato lo sforzo di innovare i processi produttivi del passato. Forse quello meriterebbe di essere più sviluppato, è l’intreccio tra una conoscenza riferita agli impieghi remoti del materiale e una conoscenza mirata al futuro di questa tecnologia antica.

Abstract
A sort of dual perspective between past and future is required when tackling the subject of earth as a building material. On the one hand, the earthen architectural heritage built since time immemorial represents a relevant field of investigation because of its documentary value and the specific problems of conservation. On the other hand, earth is often proposed as a valid alternative in building today, as part of a widespread trend towards sustainability. The need to better conserve the testimonies from the past and the unavoidable effect on the environment of the technical choices taken with regard to new buildings, lead in a single direction: the centrality of knowledge. After decades of study carried out, it can be asserted that there is no lack of basic information regarding materials and techniques of employment, and it must be said that efforts to update productive processes from the past are rather advanced. Perhaps one of the limitations might be that there have only been sporadic occasions when knowledge regarding bygone utilization of the material, and knowledge aimed towards the future of this ancient technology.File | Dimensione | Formato | |
