Positive City ExChange
Our Lighthouse Cities, Trondheim Kommune and Limerick City and County Council are developing feasible and realistic demonstration projects in climate-friendly and sustainable urban environments
The consortium is called +CityxChange (Positive City ExChange)
We are very happy to announce that the city of Trondheim has finished its Bold City Vision! Led by Astrid Haugslett and Kelly Riedesel, Vision for Sustainable Urban Transition – Bold City Vision – is Trondheim’s guide to becoming an energy positive city by 2050. The team also included Silja
Since August 2021, Trondheim Municipality has partnered with Green Edge Compute to develop a sustainable data centre at Sluppen. The construction and installation go as planned, and the new data center will rely on renewable energy and reduce close to 40 percent of energy consumption than traditional data centers. While
Trondheim is among the cities that the EU Cities Mission has selected for its major programme “100 Climate-Neutral and Smart Cities by 2030”. This underscores Trondheim’s ambitions and activities towards becoming climate neutral by 2030 as an EU Mission City. The EU Mission has selected 100 cities within the EU and

+CityxChange is a smart city project granted funding by the European Union’s Horizon 2020 research and innovation programme. Norwegian University of Science and Technology (NTNU) is the host and leads the consortium together with the Lighthouse Cities Trondheim and Limerick.
+CityxChange brings the two aspiring Lighthouse Cities Trondheim (NO) and Limerick (IE) together with their distinguished Follower Cities Alba Iulia (RO), Pisek (CZ), Võru (EST), Smolyan (BG) and Sestao (ES), to underline their ambition to achieve sustainable urban ecosystems that have zero emissions and establish a 100% renewable energy city-region by 2050.
In the future, municipalities must handle a completely different complexity in society. In order to have well-functioning cities, cities must improve how they utilise their resources and how they engage with technologies in different ways. A smart city will use digital technologies to enhance performance and wellbeing, to reduce costs and resource consumption and to engage more effectively and actively with its citizens.
The +CityxChange vision is to enable the co-creation of the future we want to live in. This includes the development of a framework and supporting tools to enable a common energy market supported by a connected community. This leads to recommendations for new policy intervention, market (de)regulation and business models that deliver positive energy communities integrating e-Mobility as a Service (eMaaS).
Our innovation and demonstration projects are organised as 11 Demonstration Projects.
The consortium comprises 32 partners covering the entire value chain for the project. The cities are involved in all aspects of the project. They are supported by two Universities, nine Large Enterprises, two Distributed Network Operators, nine SMEs and three non-profit organisations.
This project has received funding from the European Union’s Horizon 2020 research and innovation programme under Grant Agreement No. 824260.

Trondheim is situated in central Norway by the Trondheim Fjord and is Norway’s third most populous city. Trondheim is situated where the river Nidelva meets the Trondheim Fjord, and is known as an important harbour city. The city is the major public transport and logistic hub in Central Norway and Mid-Scandinavia. Trondheim has a population of about 190,500 people, with the wider region exceeding 280,000 inhabitants. The core of the city has a total urban area of just over 340km2, with a population density of 557 per km2. Trondheim is a strongly growing city, with a low unemployment rate (2.5%).
The Municipality of Pisek has a population of approximately 30,000, an urban area of just over 63km2 and a population density of 475 per km2. Písek is considered a mid-sized city situated in the South-Bohemian Region of the Czech Republic, approximately one-hour travel time to Prague. Its economy has been significantly strengthened by foreign direct investment (FDI) in the industrial zone north of the city, with strong influences from the automotive industry and electro-technics. The Technology Centre Písek and Centre of Low Energy Buildings are two innovation centres built as ‘brownfield site investments’ at a total investment cost of €40M.
Sestao City has a population of approximately 28,300 (2016) with an urban area of 3.5 km2 giving with a population density of 8,085 persons per km2. Sestao is located in Bizkaia, one of the three provinces of the Basque Country. Situated on the left bank of the Nervion River, Sestao belongs to the shared conurbation of Bilbao, Barakaldo, Portugalete and Santurtzi. The city is very well connected to the surrounding communities through road, rail and metro, and a future tram development, which will connect the city to the Leioa Campus
of the University of the Basque Country, making the commuting system more efficient and sustainable through an intermodal station.
With a population of almost 74,000 and an urban area of 104km2, Alba Iulia has a population density of 713 per km2. Alba Iulia is located by the Mureş River in the heart of Transylvania in the central part of Romania. Cultural heritage and tourism are of significant importance for Alba Iulia. The historical centre is highlighted as a geometric centre and also as the core of the urban organisation. The Alba Carolina Citadel, the most representative Vauban Citadel in Romania, outlines the city of Alba Iulia. After a series of large rehabilitation projects over the last decades of more than €70m, financed by EU funding (ESIF), the Municipality has enhanced the city’s cultural heritage and provide the opportunity for both citizens and tourists to explore an area.
The Municipality of Smolyan is situated in a mountainous region in South Bulgaria on 1000m above sea level, in the heart of the Rhodope Mountains, near on the Greek-Bulgarian border. Smolyan is 250km away from the capital Sofia and 100km from the second largest city in the country – Plovdiv. The cross-border checkpoint with Greece (Zlatograd-Thermes) is situated only 55km from Smolyan. The opening of another point in the near future – Elidge border checkpoint, only 30km away from Smolyan, is on the way, which will be the fastest link with Xanthi and the Northern Aegean coast.
The most problematic issue for Võru town is that people are moving out from Võru town to surrounding municipalities or bigger cities in Estonia. The centre of Võru and heritage area is week and poor from activities, which is why people are moving away from the centre to live in the suburb areas of the town. As there are no universities in town, young people move to other towns in Estonia or abroad. Insufficient public transport, is also an important factor, in residents moving to larger cities. There is urgent need to bring people and life back to city centre, to make heritage area attractive place to live and have business and to reconstruct buildings to make them more energy efficient.
Located on the western periphery of Europe, within close proximity to Shannon International Airport and Shannon Foynes Port, Limerick is Ireland’s third largest city and designated as one of Ireland’s Gateway Cities under the National Spatial Strategy (2002); it has held the title of Ireland’s Smarter Travel Demonstration Area since 2012. The city has excellent
connectivity with the other large urban centres of Ireland through high-quality road and rail networks. Limerick’s historic core, within the contemporary urban centre has grown in a sustainable and resilient manner that has harnessed the unique location as one of international importance.
