3 Projects
The Smart Cities Marketplace provides you with vital knowledge to support you in moving your smart city ambitions forward. Here you will find use cases from more than 90 successful European projects, including 18 Lighthouse projects, sharing solutions implemented in both small and medium-sized towns and in metropolises such as London, Barcelona and Vienna. Many projects have reported their core data into our Self-Reporting Tool, to be picked up and developed into bankable solutions.
CITY-ZEN Site Amsterdam
Location
Description
The city of Amsterdam has over 850,000 residents from 180 different countries, who own more than 600,000 bicycles. The wider Amsterdam Metropolitan Area has close to 2.5 million inhabitants. The city has a strong commitment to encourage green research, development and investment in sustainable initiatives. As a result, the area is enjoying a rapid uptake of electric transportation and a growing number of companies are developing sustainable products that influence global business. Amsterdam is exceptionally well connected, both physically and digitally.
The city has acted in line with the EU’s 20-20-20 climate targets and has the ambitious goal to reduce CO2 with 40 % compared to 1990 by the year 2025. The City-zen project was one of the major projects in which the city worked with its partners to scale up innovative energy solutions and open networks.
The demonstration objectives of City-zen in Amsterdam were focused on retrofitting existing housing, making the e-grid smarter, and improving and expanding the heat grid.
Lessons Learned:
In 5 years of City-zen, the 20 projects yielded many lessons learned.
Top 3 lessons learned overall:
1. Connect
Although it is far from easy, it is also highly advisable to organize peer meetings and exchange ideas between teams from different cities as the meetings will lead to deeper levels of understanding
2. Plan time
Even when fully involved in the implementation of solutions it is important to devote time for experience sharing and dissemination
3. Empower citizens
Involve citizens/inhabitants and truly put them at the heart of the solutions' implementation

Learnings per project (for example, smart grid projects, retrofitting projects, etc) can be found in the project reports on this page: http://www.cityzen-smartcity.eu/home/reporting/deliverables/
Demo Site Expected Impact
*Information regarding the technical and financial performance will be available at a later stage.
The total CO2 emission savings amount to 7 500 tonnes per year.
Technologies
Buildings and energy
The technologies used in the various projects that were developed during the 5 years of City-zen are plentiful. Examples are:
- the development of a methodology, resulting in a Roadmap
- various smart grid technologies such as Virtual Power Plants, Vehicle-to-Grid applications, End-to-End smartification
- innovative heating and cooling technologies such as using drinking water for pharmaceutical cooling and using river water for sustainable comfort cooling
- transforming building stock to Nearly Zero Energy Buildings, using insulation, PV and PV-T panels, smart meters and energy storage in tertiary buildings among others

SINFONIA Site Innsbruck
Location
Description
The city of Innsbruck in Austria (120 000 inhabitants) defined its 2025 Energy Plan back in 2009. In this context, and as part of the SINFONIA project, the city has selected its eastern district to demonstrate the large-scale implementation of energy-efficient measures, with the objective of achieving on average 40 % to 50 % primary energy savings in the demo sites, and to increase by at least 30 % the share of renewables in the district’s energy mix.
Demo Site Expected Impact
* Further information regarding the technical and financial performance will be available at a later stage.
As a result of the energy efficiency, the final energy consumption in Innsbruck will be reduced from 99 kWh/m²/yr (business as ususal) to 47 kWh/m²/yr, according to design data. This amounts to 535 MWh/yr of final energy savings for the two buildings reported by the project so far. The total primary energy savings go up to 607 MWh/yr while the CO2 reduction is 164 tonnes every year. These positive environmental values represent the expected results of the project and are likely to increase when more information is reported.

* Information regarding the economic performance will be available at a later stage.
The implemented measures in Innsbruck are:
Energy efficiency in buildings
- Retrofitting the building envelope
- 66 000 m² of residential and public buildings from the period 1930 to 1980 are to be retrofitted to dramatically improve indoor quality and energy performance, and reduce the final energy demand by up to 80 %
- Building integrated renewable energy sources
- Integration of renewable energy sources on-site (photovoltaic, solar thermal)
- Heat pumps
Energy systems integration
- District heating and cooling
- The district heating network is to be extended and optimised to increase the use of renewable energy sources by 95 % and reduce the use of fossil fuel by 22 %. Solar energy and innovative biomass gasification are to be integrated into the network.
- Polygeneration
- Waste heat recovery
- Recovery of heat/cold from local industries, wastewater and geothermal heat from the Brenner Tunnel
ICT
- Smart electricity grid
- Smart grids and smart home applications are planned to combine demand and supply-side measures to reduce the overall electricity demand by 3 %. Buildings are to be transformed to smart urban model houses. Measures include the smart load control for refrigerators, water boilers and heat pumps, and the involvement of customers.
