4th Webinar: Two case studies of smart ZEB: the LEAF House & the LEAF Lab organised by AEA / Loccioni Group
The Leaf House and Leaf Lab were presented as they constitute a best practice Smart Residential Building and the first connective industrial building in EU respectively. The structural and operational facilities of both buildings were highlighted. The Leaf House is south oriented with a very low U-value building envelope with solar tubes for lighting comprising 6 apartments. Systems installed include 20kW PV with 5.8kWh electric storage, solar thermal panels, rain water collecting and treatment system, geothermal heat pumps, hot water storage and air handling unit with natural preconditioning. The Leaf House is an open laboratory with the following types of sensors:
- indoor comfort (temperature, humidity, CO2)
- thermal and electrical measures
- energy consumption
- rain water level
Building controls in the Leaf House apartments consist of touch screens allowing tenants to adjust the desired temperature, switch lights, monitor energy consumption, check if windows and doors are open etc.
The Leaf Lab is a high-performance productive building constructed to be in harmony with the surrounding environment. Architectural and engineering design parameters allow for comfort of people while working and low management costs. The initial investment was just about 20% higher compared to conventional industrial constructions. The Leaf Lab has a total area of 6000 m2 and annual energy consumption of just 4kWh/m3. It is independent of natural gas and classified as A+ with regards to its energy efficiency. Systems installed comprise a rooftop PV 235kWp, electric and thermal storage systems, free and natural cooling systems, ground water pumps, advanced lighting systems etc. All systems are integrated and controlled through “MyLeaf: a proprietary Building Energy Management System created by AEA / Loccioni Group.

9th Webinar – Smart Grids district heating/cooling and cogeneration organised by IDEA
The main objective of the fourth 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.
