In western countries, we are now living in a period of economic prosperity. This has undermined in a certain way the “world’s balances” in terms of social, economic and well-being equilibrium. In particular, well-being grows in parallel with its side effects: it allows the population to grow, which generates a rise of the resources need, with related risk of pauperization of the planet. The two main aspects of the current world’s living system crisis are climate change and widespread poverty, even and mainly in terms of lack of housing. Until some years ago one was the cause of the other: the building sector is the most energy consumer and CO2 emitter. Anyway, thanks to the contemporary knowledge and technology, this trend is inverted: it is now quite simple, and in several countries compulsory, to realize NZEB or ZEB constructions. However, especially in growing countries, the building industry is yet too slow to meet the contemporary changes which are consistently faster and pressing. The main theme is now to explore the possibility of generating a new building system which can be fast in construction, adaptable to changes and completely fade away. It must respond either to growing needs or to change during the time. All focusing on very low energy consumption in use and to production/disposal phases.
