Abstract The main objective of this communication is to determine the characteristics and requirements of the BIM model, in particular in relation to the BPS energy analysis, to be used as a project tool that supports sustainable management in existing hospital establishments. With this objective, BIM architectural models and environmental simulations of representative buildings in Chile and Spain were carried out to review and propose attributes of sustainable models that allow a better adaptation to growth and flexibility from the early stages of design and restructuring. This study associates low energy consumption strategies for hospital establishments. The study is aimed at the integral management of both the operation of the building and all the services involved in its use and exploitation. This will allow to discuss the paradigm changes regarding the training of the architect and the specialists involved in the design, construction and operation of more sustainable projects.
