    Buildings energy efficiency plays a key role in terms of reducing energy consumption and improving the internal comfort. For this purpose, European standards regulate the use of different insulation systems, applied to the internal or external building envelope. However, different studies demonstrate that considerable thicknesses of insulation layers are inappropriate in our Mediterranean climates. This paper presents an innovative dynamic ventilated insulation system able to overcome condensation and overheating phenomena, also exploiting Internet of Things (IoT) technologies. This system, called S-MUnSTa, is a ventilated external layer equipped with valves of insulating material, for opening (in summer) and closing (in winter) the air channel, with the aim to optimize the thermal performance. Moreover, in order to control and manage the valves, a wireless controller system based on IoT technologies has been adopted. The proposed solution, exploiting a photovoltaic system as power source, has been also compared with a wired one alternative. The combination of building and IoT technologies develops an innovative system with several advantages, such as: the improvement of internal comfort and energy saving during the whole year controlled with a wireless system, the ease of installation and the versatile use in walls and roofs in every building typology.

    Modern ICTs are definitely a key factor to develop the green and sustainable applications that the so-called “smart city” actually needs. Effective management of resources, gathering and interpreting data as well as ecological considerations are prerequisites to turn such a vision into reality. The European FP7 project DIMMER (G.A. 609084) address these issues by providing a flexible IoT-driven platform for application development and data integration, exploiting information about buildings, energy distribution grids and user behaviors. Among those applications, the possibility to real-time access and aggregate information about building environmental characteristics and energy consumption enables the optimization of energy management and control, as well as the user’s awareness about, which is the scope of the DIMMER project. The paper will describe the ontology-driven approach, as well as the actual design, exploited to model the physical world within the context of this project, with special emphasis on the state of art research in the field of energy profiling.

  3. A Framework for Thermal Building Parameter Identification and Simulation
    Sigmundo Preissler, Jr (Sapienza University of Rome, Italy)

    The electrical-thermal analogy can be used in order to simulate heating behavior in real situations. For this purpose, several simulation tools are used. This work-in-progress paper presents a framework to identify capacitance and resistance parameters from a monitored room in a Smart Building context using OpenModelica. The proposed framework is compared with NGSpice RC Circuit as an analogy.
