8. Conclusion: a first step

This inventory, which is by no means exhaustive, leads to two observations.

The concept of sustainable development appears particularly useful for articulating different constructive solutions in a progressive manner. On the contrary, it allows us to consider technical design as a combination of choices that must be graduated according to the project context. In this way, the emphasis is placed on the responsibility of the decision-maker, who must seek a satisfactory solution each time, rather than the definitive solution. The building is not just a physical object, but also a system interacting with the end user. In this sense, design is above all about anticipation.

However, the multiplicity of possible solutions that has been outlined demonstrates that construction requires time for re-engineering. The multiplication of points of view...
