From District Information Model ( DIM) to Energy Analysis Model (EAM) via interoperability

Energy saving for existing buildings is considered one of the most important issues in the last years for the development of a smart city. The DIMMER (District Information Modeling and Measuring for Energy Reduction) project starts from the development of a 3D parametric model, able to collect heterogeneous data at different scale. It aims at improve the energy consumption optimization, monitoring real-time data and simulating all energy flows. Starting from Building Information Models (BIMs), based on the development of DIM models, it is possible generate an Energy Analysis Models (EAM) able to simulate building energy usage compared with indoor temperature coming from real time temperature sensor. Finally, the DIMMER project is focused on management, modelling and visualization of different data that describes the district, connecting different data-sources with different level of information. In order to achieve these goals, interoperability is considered a crucial step for sharing data between different environments, across various software and different professionals.
