When reflecting on recycling, sustainability, measures to take, and innovative technological solutions, one cannot help but think that there are also familiar approaches that should be taken into consideration. In fact, when examining the impact of the built environment on the climate, one notes that in many countries, 80% of the buildings that will exist in 2050 have already been built. The most effective form of sustainability may, therefore, be saving energy by eliminating or minimizing new constructions, and by avoiding the demolition of existing structures.
