2 Greenovate! Europe is an independent, not-for-profit membership organisation. Profile Our partners are found in 14 EU countries encompassing 500 innovation experts and 2,000 technical experts making us a one-stop shop for sustainable solutions. Our mission is: To pool eco-innovation expertise; To offer green innovation services for technology developers, companies and policy-makers at pan-european level.

3 Smart City projects Duration October 2017 September Demos Tampere, Pamplona, Trento 3 Early adopters Derry, Kozani, Litomerice Focus area(s) Building refurbishment, Renewable energy integration, District heating/cooling, Electricity distribution, Sustainable mobility, Integrated ICT systems N of partners 27

4 European cities serving as Green Urban Gate towards Leadership in sustainable Energy Duration April 2013 March Demos Milan, Vienna, Tampere, Bratislava, Aachen, Sestao 3 Follower cities Gothenburg, Gaziantep, Plovdiv Focus area(s) Building refurbishment N of partners 27

5 Vienna District Surface affected Type of buildings Target Penzing ~68,783m² residential buildings and social housing from the 50s and 70s, owned by tenants and flat owners Up to 61% primary energy savings Technical measures: High insulation and decentralised ventilation. Thermo dynamic optimisation via simulation and monitoring. Multi-Active Façade combined with PV. Building Integrated PV (BIPV) combined with heat pumps, solar thermal integrated in district heating. Replacement of decentralised fossil heating systems by centralised renewable heating plants allowing contracting. Non Technical measures Socio-economic evaluation. Participatory action research. Symbiotic integration of green power marketing.

6 Tampere District Surface affected Type of buildings Target Tammela 32,463m² Apartment blocks mainly from the 70s, largely owned by private households. Up to 50% primary energy savings Technical measures: Insulation measures (walls, windows, balcony doors, roof) Renewing the thermostat valves and adjusting the heating network Renovation of the heating system Solar panels Adding heat recovery to the ventilation system Air-source heat pump Metering for water consumption in every apartment Renovation of the drainpipe system Energy efficient lighting Remote monitoring of the properties Non Technical measures Specialized events for the residents and the other parties on energy efficient and environmental friendly renovating, building and living Promotion of the use of bicycles

7 Aachen District Surface affected Type of buildings Target Aachen-North ~41,000m² Recent (70s) and historical buildings (20s-30s) Up to 65% primary energy savings Technical measures: Insulation measures on facades, roofs, cellar ceiling, windows Heat-recovery from ventilation and sewage Heat pumps integrated in a low-ex heat network Technical control systems for heat, electricity and lighting Solar energy and efficient gas boilers Presence detectors for lighting Smart meters District heating Non-technical measures Energy efficiency rental fee and other agreements with tenants, Communication measures and advisory activities to reduce energy consumption through consumer behaviour.

8 Bratislava District Surface affected 8,000m² Type of buildings Blocks of buildings built after 1960 Target From 60 to 75% primary energy savings Technical measures: Insulation measures on facades, roofs, cellar, ceiling, windows Solar thermal and PV. Gas boilers with micro CHP Heat recovery from the sewage Smart meters Non-technical measures Financing models adapted to privately owned apartments (no social housing) Raising awareness of tenants, to reduce energy consumption through user s behaviour

9 District Zona 4 Surface affected 17,596m² Type of buildings 3 residential blocks and a public school Target From 66 to 80% primary energy savings Milan Technical measures: Prefabricated Facade with Built-in Mechanical Ventilation & Heat Recovery System External insulation without glue Advanced Solar Protection, Night Cooling Ventilation Heat recovery system (Exhaust air pump) Building Management Systems. Smart Meters Photovoltaic power plant Non-technical measures Creation of an energy efficiency and deep renovation team inside the technical staff of the municipality Showcase information centre to give information and training Awareness raising campaign

10 District Surface affected Type of buildings Target Txbarri / El Sol 19,142m² Social housing blocks, 222 dwellings From 66 to 80% primary energy savings Sestao Technical measures: Insulation measures on facades, roofs, cellar ceiling, windows Sustainable building materials Installation of biomass boilers and Solar Collectors Addition of heat recovery to the ventilation system Non-technical measures Awareness raising campaign Promotion of the use of bicycles

11 Smart INitiative of cities Fully committed to invest In Advanced large-scaled energy solution Duration June 2014 May Demos Innsbruck, Bolzano 5 Early adopters Rosenheim, Seville, Boras, La Rochelle, Pafos Focus area(s) Building refurbishment, Electricity distribution, District heating/cooling N of partners 37

12 Innsbruck Building refurbishment: Improved envelope (insulation, windows, thermal bridges,...) Ventilation system with high efficiency heat recovery Integration of renewable energy sources on-site (PV, solarthermal, heat pumps) Electricity grid: Smart load control for refrigerators, water boilers and heat pumps Establishment of new ESCOs Involvement of customers District heating and cooling: Deployment of a low temperature grid Recovery of heat/cold from local industries, wastewater and geothermal heat from the Brenner tunnel Integration of solar energy and innovative biomass gasification

13 Building refurbishment: Building envelope insulation Integration of renewable energy sources for electricity, heating and domestic hot water, Solar panels Additional storeys using innovative timber construction technologies Bolzano District heating and cooling: Real time monitoring and forecasting of peak loads and energy demand Hybrid hydrogen/methane backup system Feasibility study for recovery of wasted energy in the local industrial park Electricity grid: Recharge points for vehicles and bicycles Meteorological stations for local climate condition monitoring Smart retrofitting of the public lighting system

14 Beyond the Replication Cluster, a larger community of smart cities My Smart City District community 7 projects (including Sinfonia & EU-GUGLE) for a total of 22 demo cities Each project with its own knowledge exchange activities Only one website to access them all: Presence on social media: LinkedIn Group: My Smart City District

15 Innovative insulation material and renewable integration

16 Flexible and sustainable multifunctional module for architectural design, combining: Light weight transparent and recyclable ETFE plastic PV module for electricity generation Illumination devices (LED) for image and pattern display Flexible integrated circuits for control of the PV and LEDs External battery for electricity storage
