The paper presents a research work concerned with the integrate assessment of seismic vulnerability and energy performance of existing buildings at urban scale through BIM (Building Information Modelling).At the urban scale, it is often required to manage large set of buildings, for which it is not possible to perform detailed investigation, modeling and analysis. At this scale of analysis, an additional issue is the coexistence of different building components and performance requirements (structural safety, functional and aesthetic efficiency, energy efficiency, and so on), which often have a dynamic interaction.For this reason, the modeling approach should be able to encounter this complexity and provide the interaction of multiple expertise, in order to provide optimal solutions of the critical issues and vulnerability of buildings.Within this context, the research has proposed and tested a framework structured through a suitable BIM model finalized to implementation of integrated simplified evaluation procedure of seismic vulnerability and energy performance at urban scale.The objective is to provide an innovative tool for the performance-based assessment in a context of uncertainty and incomplete information typical of the urban scale analysis.The proposed approach allows to manage information from different source and quick investigations concerns structural safety and energy efficiency, and it has been focused on the case study of "Fiera del Levante", a trade fair district extending over 280.000 m 2 , composed by several buildings aged from 1929 to 2012, that host about thirty events (including international fair shows) throughout the year as well as conferences and/or exhibitions.
