Et si ? Construire et rénover autrement

The exhibition presents about thirty buildings, mainly from Normandy, implementing techniques of bio-sourced materials: straw, hemp, earth, wood.
The projects presented - both new constructions and renovations - illustrate practices that are sustainable, local and often frugal. Inspiring examples to make visible the act of building and renovating differently and accompany the ecological transition of our territory.
More and more, the world of construction is taking its part in the transition of our society. Thus, the exhibition: "What if? Building and renovating differently" presents to the largest number of people, achievements and renovations that have in common to act in favor of the environment, in a shared will between the owner and the contractor. These buildings take into account various contexts and types of projects, with ecological constraints and adapted regulations. All of these responses contribute to the evolution of practices through their technicality, their construction methods? and their audacity!
The exhibition is presented by type of operation, in order to address both individuals looking for a virtuous house project and professionals who are responsible for proposing architectural solutions that meet the expectations of a society concerned about its future. It is also addressed to elected officials and social landlords so that they dare to place ambitious and socially responsible public orders. For example, in Normandy, the objective for the coming years is to renovate 30,000 homes. If this exhibition can be a source of inspiration for these projects to meet the environmental challenges, it will have fulfilled part of these objectives.
"What if? Building and renovating differently" also offers models and materials to touch, technical presentations of bio-sourced materials (straw, hemp, earth?) as well as research work carried out to identify the materials of tomorrow and their possible uses.
