Yes, it is necessary to limit and rationalize the use of the material resources used in the architecture, as well as the consumption that derives from them, but all these impacts do not depend so much on the quantities of the materials that we use but HOW we use them.To understand how we should approach a project and the use of constructive technologies, we would have to delve into the consequences of the following premises:• “A building is not something you finish. A building is something you start “• “In a culture of salvageable construction, buildings may be seen as ‘material banks’ for the future.”In this sense, the path that best responds to the closing of the cycle of materials is one that develops the idea of: “The purchase of resources vs.. the rent of utilities “.
These premises have far-reaching consequences when it comes to thinking about the project and choosing the best construction technologies that enable roads for sustainability, and this does not happen exclusively through the choice of material. The material is not a condition of the building’s environmental impact. We must understand that the sustainability associated with material resources does not depend on some of its environmental characteristics (such as energy, emissions, etc …) but depends on the use and the utility that we give it when we transform them into constructive elements and systems, when these enter into ‘service’.
In this way, project strategies that are able to adapt to the demand and grow according to it, and not in false optimizations that leave empty architectures of use in many periods of its useful life, should be foreseen.
