Prodotti da costruzione in un'ottica di sostenibilità ambientale. Parte 1*

The international scientific community agrees that an accurate assessment of the environmental sustainability of buildings cannot disregard some basic requirements: • a Life Cycle approach; • an harmonized LCA methodology; • a full life cycle assessment of building and building products or, at least, the assessments of impacts during production, use and end of life phases, as well as the expected benefits from the potential reuse and recycling activities at the end of the reference service life; • a comparison based on the same functional equivalent • the use of homogeneous datasets • an assessment that includes all mandatory indicators These requirements preclude any possible generalization, that defines an element, a component or even a material, preferred over another, outside of a specific and contextualized scenario of analysis. Therefore, and on the basis of the most recent scientific bibliography, this document offers a critical review of the results and of the uncertainties, which emerged from the ore recent research studies on sustainability of renewable materials used in building construction.
