In all areas, man has tried to improve the performance of his homes, both in terms of comfort and hygiene. To obtain these results, he first tried to make what nature had made immediately available to him: sites suitable for building, natural shelters, soil protection, sunlight and heat, as well as materials to be used (wood, stone, earth, clay, etc.)

This led, first on an intuitive level, then on an artisan level, an attention that constituted “architecture”: the choice of the site for the construction, the choice of the best orientation towards solar exposure and of the winds, the choice of building materials, the “project” of the housing typology and its structure.

Over time, the architectural project lost its artisanal character, to assume more and more a technological character. With the increase of knowledge and technological skills, man exploited the possibilities offered by nature, creating artifacts that could improve the quality of his homes. The sites were modified with bricks, glass, sewage systems, insulation were made. Until the nineteenth century, attention to the sustainability of an architectural project was still fundamental, especially due to the limits deriving from the scarcity of the energy resources available.

Things change radically with the possibilities offered by the exploitation of fossil fuels. The enormous amount of energy available, combined with technological progress, had made possible the heavy renovation of building sites, the creation of innovative materials and equipment, and the release from traditional energy resources. Architecture collects the fruits of progress, focusing on the maximum possible realization that technologies allowed.
