This topic involves the creation of a 3D city model considering heterogeneous datasets, such as Building Information Models (BIMs), Geographical Information Systems (GISs) and System Information Models (SIMs), taking into account both buildings and the energy network. Through the creation of a common platform, the data sharing was allowed starting from the needs of the users, such as the public administrator, the building manager and the energy professional. For this reason, the development of a District Information Modelling (DIM) methodology for the data management, related to the energy saving and CO2 emission, is considered the focus of this paper. It also presents a specific tool developed for the comparison of energy data in a selected district: the Benchmarking Tool.

International literature is demonstrating that involvement and awareness in facility management can help energy saving. For this reason, it is necessary that the subject becomes active and able to fit inside the energy management information. From this point of view, the Smart Energy Efficient Middleware for Public Spaces (SEEMPubS), a Seventh Framework Programme project, aims to reduce energy consumption in historic and modern public buildings through low economic impact construction works and an efficient ICT network for monitoring, detecting and managing consumption. At the end of this project, consumption data, which were collected within a number of the test rooms, will be available to end users through a Facility Management application (Archibus) that will allow users to see energy consumption data visible in real time, and to perform a different kind of medium and long term analy...

BIM is the methodology that enables the sharing of graphical and alphanumerical information among different professionals. The developed methodology fitted during these years is described for several projects, and it is always composed by three phases: survey and documental research; digital modelling and data interpretation; data exploitation through interoperability. BIM process still does not reach an optimized interoperability level, but this represent the added value of technological innovation for construction industry, as a tool for information sharing.

The main purpose of this large effort is to reduce the effects of greenhouse emission, climate change to head for a sustainable society. In this scenario, Information and Communication Technologies (ICT) play a key role. From one side, advances in physical and environmental information sensing, communication and processing, enabled the monitoring of energy behaviour of buildings in real-time. The access to this information has been made easy and ubiquitous thank to Internet-of-Things (IoT) devices and protocols. From the other side, the creation of digital repositories of buildings and districts (i.e. Building Information Models-BIM) enabled the development of complex and rich energy models that can be used for simulation and prediction purposes. As such, an opportunity is emerging of mixing these two information categories to either create better models and to detect unwanted or inefficient energy behaviours. In this paper, we present a software architecture for management and simulation of energy behaviours in buildings that integrates heterogeneous data such as BIM, IoT, GIS (Geographical Information System) and meteorological services. This integration allows: i) (near-) real-time visualisation of energy consumption information in the building context and ii) building performance evaluation through energy modelling and simulation exploiting data from the field and real weather conditions. Finally, we discuss the experimental results obtained in a real-world case-study.

In order to move forward this view, a city district model is needed, which takes into account different datasources such as Building Information Models, Geographic Information Systems and real-time information coming from heterogeneous devices in the district. The Internet of Things paradigm is creating new business opportunities for low-cost, low-power and high-performance devices. Nevertheless, because of the "smart devices" heterogeneity, in order to provide uniform access to their functionalities, an abstract point of view is needed. Therefore, we propose an distributed software infrastructure, exploiting service-oriented middleware and ontology solutions to cope with the management, simulation and visualization of district energy data.

In this scenario, we present an innovative solution for combining BIM (Building Information Modelling) data with ambient information collected by heterogeneous devices deployed in the building. In order to collect environmental information, we exploit in this work a distributed software architecture. It enables the interoperability between heterogeneous data-sources, either physical devices like sensor nodes or third party software like Archibus, where building information resides. On top of this infrastructure, we developed an Android-based application that presents environmental building information integrated with BIM data in an Augmented and Virtual Reality environment. The proposed solution provides users awareness about building conditions and energy consumptions.

The proposed platform enables the interoperability and the correlation of (near-)real-time building energy profiles with environmental data from sensors as well as building and grid models. In a smart city context, this platform fulfills i) the integration of heterogeneous data sources at building and district level, and ii) the simulation of novel energy policies at district level aimed at the optimization of the energy usage accounting also for its impact on building comfort. The platform has been deployed in a real world district and a novel control policy for the heating distribution network has been developed and tested. Results are presented and discussed in the paper.

On the other side, advances on 3D modelling, visualization and interaction technologies enable user profiling and represent part of the holistic approach which aims at integrating renewable energy solutions in the existing building stock. To unlock the potentiality of these technologies, the case study selected for this research focuses on interoperability between Building Information Models (BIM), GIS (Geographic Information System) models and Energy Analysis Models (EAM) for designing Renewable Energy Strategies (RES) among the demonstrator. The objectives aim at making a whole series of data concerning the energy efficiency and reduction at district level usable for various stakeholders, by creating a District Information Model (DIM). The described system also integrates BIM and district level 3D models with real-time data from sensors to analyse and correlate buildings utilization and provide real-time energy-related behaviours. An important role is played by the energy simulation through the EAM for matching measured and simulated data and to assess the energy performance of buildings starting from a BIM model or shared data. With this purpose interoperability tests are carried out between the BIM models and quasi-steady energy analysis tools in order to optimize the calculation of the energy demand according to the Italian technical specification UNI TS 11300. Information about the roofs slope and their orientation from the GIS model are used to predict the use of renewable energysolar thermal and PVwithin the selected buildings (both public and private) of the demonstrator in Turin, Italy.

The BIM of the Politecnico di Torino (Polito) campus used in the Smart Energy Efficient Middleware for Public Spaces (SEEMPubS) project is an integrated representation of each building to merge architectural, structural, electrical and HVAC elements and components. In the Polito campus there are three types of buildings: historical, modern and contemporary. A special approach has been adopted to model and to exchange data between software about historical buildings because they are characterized by paints, stuccos, etc. The aim of this research was to set a parametric model able to share information without data loss, testing the interoperability between architectural software like Revit Architecture and lighting analysis software like Daysim and Radiance. As the process of exchanging data from Revit to Daysim and Radiance is not direct, Ecotect Analysis was used as an "interoperable bridge" with good results. Three different formats were tested: IFC, gbXML and FBX and for each one problems and possible solutions were analysed. Up to now, Ecotect was used in two different ways: to define material parameters before the export phase and to visualize analytical data obtained from Daysim and Radiance. In our tests some errors have occurred referring to data retention like material properties, but at present the main problems have been solved. Indications about performance of daylighting and energy consumption have been obtained, although a lot of work should still be done. The correct data exchange that we obtained enabled the optimization of the building simulation process by avoiding the need to remodel the same building in the lighting applications.

DIMMER is a distributed software infrastructure for information modeling and energy management that correlates such information with user behavior patterns and feedback. For the smart city vision to move forward, ICT must be a key player 1 in enhancing energy optimization in cities. 2 At the building level, monitoring and control solutions have been developed along with user-awareness policies to promote green behaviors. 3 Real-time information about environmental characteristics and energy consumption can be accessed from pervasive devices deployed in a building. At the district level, information about heating distribution networks and the power grid can be accessed by sensor networks. In this context, heterogeneous devices are involved in the monitoring and management processes of buildings and grids. Facilitating information exchange between these heterogeneous devices is an issue that can be overcome thanks to middleware technology. Indeed, middleware can help enable interoperability across heterogeneous data sources, either hardware or software, and provide an abstract view of their functionalities. Once interoperability is enabled, information from these data sources can be collected and correlated into a common and distributed "smart digital archive" for managing energy in the district. In this scenario, different stakeholders in the smart city context can access this information or push new data. Moreover, the ICT revolution in building information modeling (BIM) 4 enables the digital organization of building characteristics and parameters. Hence, making district energy production and consumption data available to client application and control policies jointly with BIM information would increase energy efficiency at the urban level. For instance, better-performing policies can be developed that take advantage of building performance and characteristics. In addition, providing such information to client applications would increase user awareness about energy-consuming behaviors. Furthermore, feedback from citizens can be collected for a better understanding of users' behavior patterns, which can then be considered when improving energy policies at the district level. All this information enables new business models for different actors in the smart city scenario. Hence, a distributed architecture is needed that focuses on
