The schools lacking energy performance promotes deep buildings refurbishments, considering also LCC evaluation to define the cost-optimality criteria in building renovation. Moreover, available funding programs are not frequently appropriate to deal with energy law compliance because of the safety and accessibility issues are currently leading topics to be accomplished before. The governance indicates the school as the favoured centre of local community improvement and activities and the school building is advocated to encourage social interaction, clusters’ cooperation and space sharing, as a civic centre. These growing needs ask for new methodologies to approach the renovation of the school buildings considering on the one hand the energy demand and on the other hand the management of the spaces flexibility and of the whole asset during the entire life span. The method described here and applied to a case study is based on BIM to BEM procedures; it aims to demonstrate how to define a building database to store all the data able to endorse the management of maintenance strategies and energy developments, together with cost analysis for energy retrofitting
