Requalification, recovery of buildings and cutting-edge technology to design the home of the future: this is what was presented at 51° Edition of the SAIE, international building exhibition in Italy.

At the heart of the new SALT SMART HOUSE, in the Services area of Bologna fair (held like the interior of a great intelligent and sustainable house), SMART HOUSE LIVING has been presented. This project consists of 4 souls: an exhibition – Smart House Solution – on which was represented a new culture of sustainable living, which allowed visitors to ' touch ' practical applications and innovative technological solutions; a playful and participatory path – the Wheel of Sustainability – to bring the public to the culture to "triple zero" (zero consumption, zero emissions, zero waste); the Forums on the themes of designing, building and inhabiting the houses of tomorrow; the BIG Energy Idea — a ' emotional room ' of innovation told through videos and sounds: a project to push for change through knowledge.

In SMART HOUSE LIVING area, energy has been the main topic thanks to the forum "Building & Innovation". In the Digital Smart Building technology how this innovation can revive the construction industry has been the main topic. Many laid optical fiber is still unused. Since last July with the Decree Unlock Italy, "all new buildings must be equipped with a passive multiservice physical infrastructure inside the building, consisting of adequate space and installation of high-speed communications to the fiber optic network termination points". The legislation makes the provision in new homes be mandatory.
