9th Webinar – Smart Grids district heating/cooling and cogeneration organised by IDEA
The main objective of this webinar was to present an overview about district heating and cooling (DHC), its link with cogeneration, the perspectives in terms of improved efficiency, integration with renewables sources and evolution in the smart cities framework.
District heating and cooling is an integrative technology that can contribute to reducing emissions of carbon dioxide, improving air quality in urban areas and to increasing energy security. The fundamental idea of DHC is connecting multiple thermal energy users through a piping network to optimized energy sources, such as combined heat and power (CHP), industrial waste heat and renewable energy generators. Some countries in northern regions, show a significant penetration of DHC, while it still represents only a small fraction of the total heat market of the European Union. Therefore, the potential is large and varies in each country depending on past national policies. Integration of renewables, waste heat reuse, and lower operating temperature are the key issues in the present evolution of DHC, as well as the integration of more advanced IT management tools and the introduction of new business models.

10th Webinar – LEAF Community and CAMP IT organised by AEA and TUC
First part: Seminar by AEA. The seminar described the materialised activities under the LEAF initiative/project at Loccioni.
Multiple Renewable Energy Sources (RESs), consumers, Electrical Energy Storage systems (ESSs), offices, industrial and residential buildings are all successfully integrated into the Leaf Community. Sun and water produce energy to such a smart community through micro-hydro power plants distributed along a river and PV rooftop installations located on top of each building; moreover, an energy storage system is integrated with buildings of various type (four industrial, one office and one residential) and electric vehicles and bicycles improve smart transportation. Additionally, measurements from the sensors and meters placed are collected via the web-based monitoring and control platform, developed by the Loccioni Group as well, called MyLeaf. Based on that data a dedicated control algorithms, implemented on the MyLeaf platform, efficiently coordinates all the energy systems by providing the optimal signals for production and charging/discharging strategy to all the energy sources in order to minimize energy costs and satisfy energy demand in real time. The health of our earth and of man is the main goal of the Leaf Community.
The contents of the presentation is as follows:
- Loccioni for Energy
- The LEAF Community
- THE LEAF Community and the IUndustrial Micro-grid
- Loccioni Microgrid 2012
- Loccioni Microgrid 2014
- MyLeaf: Energy Management System
- Loccioni Leaf Roof
- Loccioni Leaf Water
- Storage Systems
- Electric Vehicles
Second part: Seminar by TUC. The seminar described the Camp-IT system that has been developed in TUC.
The TUC Campus can be considered a small community. The dymanic interaction between indoor and outdoor environment can contribute to the reduction of energy consumption. For that purpose, both buildings and outdoor spaces have been modelled and simulated in appropriate software. Building monitoring and prediction models have also been employed and indoor quality has also been evaluated in order to achieve parallel optimisation of energy consumption and indoor comfort. The results indicate that there are potential energy savings throughout the year with the Capm-IT system approach.
