Abstract
Abstract. The availability of integrated information on buildings is the premise for an effective assets management and the provision of innovative services to buildings users: such form of knowledge relies on the efficient exploitation of existing data, providing a complete overview on the state of buildings, and on the acquisition of real-time data flows, coming from sensor and mobile devices, reporting users behaviours. If, on the one hand, technology is progressively enabling the management of new huge streams of data, on the other hand the interconnection among traditional and well rooted datasets, the majority of which in charge of public administrations, is not always guaranteed. While, at European level, interoperability issues among public archives concerning buildings were properly addressed, and the relevance of geo-information is widely recognized, in Italy this process is still taking time to be undertaken. This paper discuss the current state of Building Information in Italy, outlining a possible path for the creation of a georeferenced Building Information System at municipal level, starting from the informative heritage available in existing databases, generated with different purposes and maintained by independent authorities: the idea is to solicit that digitalization process, started a decade ago with the “Digital Administration Code”, through the proposition of real use cases that might be implemented once that public data on buildings are profitably combined together.

New challenges related to population growth and human concentration in urbanized areas are currently soliciting governments and policy makers in the development of smart management models able to deal with increasingly complex cities
The definition of strategies aimed to improve the quality of buildings and their energy efficiency play a critical role in the reduction of GHG emissions: the Energy Performance of Building Directive 2010/31/EU recast states that buildings account for 40% of total energy consumption in the European Union and a shift toward a reduction in energy needs and new renewable sources would reduce the carbon footprint caused by the building sector
Energy estimates at city scale seem to be an interesting field of application: in its work, Agugiaro (2014) describes the attempt realize energy audits for a neighborhood of the city of Trento, creating a 3D city model starting from building footprints and LIDAR data for the modeling of geometries and integrating semantic information extracted from the cadaster
Summary
New challenges related to population growth and human concentration in urbanized areas are currently soliciting governments and policy makers in the development of smart management models able to deal with increasingly complex cities. Some European countries, as reported, started to work on data interoperability and integration issues several years ago, assuming them as a main concern at national level: in these contexts the gathering of existing data ensure an efficient management of available information, avoiding redundancies and improving data quality and the connection with georeferenced bases enabled the creation of City Models with. The intent of this work is dual: firstly to demonstrate how, even if a national strategy on public data harmonization is missing, a bottom up process might be implemented enabling municipalities to create a local Building Information System; secondly, considering current data specification on the building theme provided within the INSPIRE directive framework, to align the quality of Italian building geo-data to European requirements
