BIM-GIS Modelling for Sustainable Urban Development

The subject of energy efficient buildings incorporated into the district is one of the greatest and most challenging of research priorities in the European Union. In this context, the potentiality and benefits of the integration of Geographic Information System (GIS) – Building Information Modelling (BIM) are explored as an integrated methodology for data collection and management relating to existing buildings. The aim of this study is to create a graphical database mainly based on information that is already available on a building stock, which it will be used to evaluate the energy consumption profile at building and district scale. For this purpose, it is necessary to develop an urban model able to contain heterogeneous data considering different Levels of Development and different Levels of Detail (LOD), which can be exploited for many purposes including design, maintenance or refurbishment of buildings and energy consumption monitoring. In this way, data can be extracted for a specific calculation in different applications for assessing and supporting decision making in order to achieve sustainable urban planning. This paper is part of an ongoing Smart City research, a national cluster project named Zero Energy Buildings in Smart Urban Districts (EEB), which aims to increase energy efficiency of buildings, especially at the global level of urban districts.
