The aim of this thesis is to use a streamline method to check CESBA requirements through COBIe (Construction to Operations Building Information exchange) on an existing building adopting a light BIM approach (avoiding the 3D model construction). In this way, it will be created a data-base CESBA based, to do so it will be necessary define the BIM objects’ attribute using information coming from the building, the user’s needs and from CESBA requirements, to fulfill a considerable number of COBIe criteria attribute (about 85% of CESBA criteria will be translate in COBIe). The created data base is useful not only for the automatic sustainability rating of the actual state of the building, but also for future maintenance interventions and not only for one specific case but for other buildings with the same function, because it is used a standardized procedure. Moreover, the use of a lean approach simplifies the decision-making phase, reduces design time and increase the flexibility in planning because allows a free choice of software, decreasing the plugin implementation. The previous methodology will be illustrated through the case study of a sporting club located in the north of Italy, precisely in Gallarate in province of Varese. This study could be used as an exemplification of the use of COBIe for a leaner approach to the project, and could be exported from the “green universe” to other field of application for example the facility world.
