The different technical and legal tools intended for heritage protection have introduced the novel possibility of enjoying important monumental complexes. The divergence lies in the artistic contexts in which, due to the genesis of their programmatic typology, they require residential uses, as is the case of monasteries. This article collects the results of a long-span research, whose main objective has been to find a tool that could allow us to measure different indicators on a continuous basis in which both the protection of the elements, and the capacity for habitation, are safeguarded. To this aim we have set in context the research at the Monastery of Santa Clara de la Columna in Belalcázar (Córdoba), a location with the highest possible heritage protection of Spanish ranking which, in turn, accommodates a religious community. The results have allowed us to design innovative parameters for habitation, within a protected and endangered heritage context.
