The aim of this experience (an interdisciplinary PhD course based on the BIM methodology used in the Smart Energy Efficient Middleware for Public Spaces – SEEMPubS – FP7 project) was to investigate the team work sharing and the use of interoperability between software, to test the opportunities offered by BIM process applied at existing buildings at the campus of Politecnico di Torino. Two architectural parametric models were realized (one concerning a new building –Classroom I– and one concerning a historical building recently renovated –ISBM offices–) and imported into software for energetic and management analysis using different formats like IFC and gbXML. Several lessons have been learned from these processes in order to optimize the quantity of data that pass from one software to the other ones both for type of data and for format of exchange. This indicates that actually, there is a possibility to better the BIM process, but a support from software houses is required based on the real use of common standard. Keywords: BIM, Interoperability, Energy assessment, Augmented reality. 1. Introduction Significant benefits to be gained from the interoperability of BIM software have generated considerable recent research interest. BIM is not only the software, but it is the collaborative process, which integrates different fields of design, construction and management to obtain the optimal result in entire process of building life cycle. It is fundamental that bim (building information model) are shared and accessible in open and interoperable fashion in a way enabling data and meta-data available in bim to be accessed, pre- processed and mapped correctly with different applications. Many researchers have addressed the problem of interoperability, but there remains a need for an efficient method that caneasily transform data into different formats like IFC and gbXML for structural, energetic and management analysis. The purpose of this study is to examine and describe the teamwork sharing, interoperability between software and the opportunities offered by BIM process applied at existing buildings at the campus of Politecnico di Torino. 2. Methodology During the course, as we had two Buildings to analyse and 12 participants from different fields and background (Architects, Engineer expert on ICT, Energy, Building and Management), we have divided all the practice activities into 5 main parts as follows:  Building the model in a BIM software and sharing information using worksets and Central Model in Dropbox;  Building performance and energy analysis using several software for a better interoperability;  Feasibility of interoperable BIM and IoT system;  Building lifecycle and management using BIM;  Tablet application to show the different data by Virtual and Augmented Reality. 2.1 Building the model in a BIM software and sharing information using worksets and Central Model in Dropbox
