SUSTAINABLE TECHNOLOGIES FOR BIOREGIONALIST ARCHITECTURE. Regulatory aspects and pilot experiences

The relationship between materials used and the cultural context is a theme that brings back the inseparable link that exists between the development of a territory and the enhancement of the resources it possesses. Over the centuries this relationship has characterized the Euro- Mediterranean regions and, in particular, the smaller centers, where the relationship between man and nature is strengthened in the primordial need for living with few means, where the territorial constraints, the climate and the resources available support a proactive material culture system. These meanings, combined with digital manufacturing and mass customization, lead to a rethinking of the technological process of architecture, respecting the local historicalcultural identity, the principles of environmental protection and Life Cycle Assessment. In this way, the bioregionalism concept presents itself as an element of technical-critical continuity with the local building traditions and, also, as an “field” oriented to the development of new technologies connected to the territory in support of new housing needs. The contribution emphasizes the importance of a design approach aimed at protecting the European material culture and local diversity over the long term, through the rational use of resources, compatibility assessment of these choises, durability and resilience, in the renovation of existing buildings. Finally, this methodology considers the importance of the life cycle analysis of materials and their certification through multi-criteria methods, as well as the possibility of identifying and using new ways of manufacturing that can optimize time and ways of assembling materials.
