In the majority of studies carried out until now Life-Cycle Assessment (LCA) has been used according to a methodology based on the final evaluation of an already finished design. This article proposes a new approach of using LCA as an evaluation tool at the time of design, so making environmental-impact reduction criteria part of the decision-making process in projects so that they affect the final outcome.
However, very few studies apply Life-Cycle Analysis to heritage interventions. Taking into account the value of heritage building is necessary for planning intervention proposals with minimal environmental impact. On this matter, researchers from the Seville Higher School of Architecture have published a study in which they apply the methodology of LCA to the Roman Theatre of Itálica. Specifically, they have developed tools that link LCA and BIM software so that environmental-impact reduction criteria can be integrated into projects from the moment of their first design.
