Summary of Triangulum Replication

The replication work of Triangulum was based on three pillars:

•1. Demonstration projects in the three Lighthouse Cities helped to showcase how public and private partners can collaborate to create solutions that make cities better places to live.

•2. Triangulum assessed the demonstration projects to generate a robust evidence base describing their impacts and benefits.

•3. Triangulum developed a business model based upon the value of these benefits that enables their replication without public funding in the Follower Cities and beyond.

Main objectives of the Smart City Framework

• Streamline ICT integration of the three Lighthouse Cities to speed up planning and implementation.

• Design a replication framework and a decision- making tool for Smart City project development and implementation.

• Apply parts of this framework to accelerate the replication process in Follower Cities and beyond.

Three Phases of Triangulum (Credits: Fraunhofer)

The replication process is structured in two ways:

• A customer centric approach supporting the Implementation Strategies of the Follower Cities.

• A technology transfer approach that allows replication by cities and other partners.

Replication Tool

As a tool for replication, Triangulum has developed the „Smart City Decision Making Tool“. The aim of this tool is to foster replication of Triangulum Use Cases by enabling cities to find relevant examples from Triangulum that fit their needs.

Information included:

• Description, location, time taken for planning and implementation, public participation model, business model details, stakeholders, etc.

• Additional insights gained from implementation like lessons learned and supporting factors

Triangulum Use Cases

As an example, the replication of the Use Case Blink was a real success story for Triangulum. The local Stavanger partner Lyse AS invited interested stakeholders from the consortium to Stavanger to demonstrate how Blink works and to further underline its potential. There were talks between Lyse As and the different city representatives as well as several demonstrations of the tool. After this first meeting, the stakeholders agreed to test the solution in the Triangulum Follower Cities Prague and Sabadell. There was thus a test run in both cities where minimal required adaptations were identified and subsequently realised by Lyse AS. As a result, the Use Case Blink could be successfully replicated in both Prague and Sabadell!

Summary of Triangulum Monitoring & Evaluation

Triangulum Impacts

The following summary gives an overview of Triangulum impacts at the level of the demonstrators (modules), across the project as a whole, and at city level. Currently, these are still draft impacts as we are still checking and calculating final values. Look up our final impact report when it becomes publicly available (Deliverable 2.6, to be published here), which will contain further updates and details.

Module Level Impacts

257 impact indicators have been finalised across the 26 modules being implemented in the Lighthouse Cities. The overall impacts in the Lighthouse cities are as follows:

For Manchester, energy trials in the final year carried out showing significant potential for reducing energy demand and lowering GHGs, 10,300 m2 optimised building space in MCC for smart energy interventions with over 400 tCO2e avoided GHGs, and a further 35 tCO2e avoided GHGs as a result of PV energy generation. The purchase of 10 Triangulum procured EVs has reduced GHG emissions by 35 tCO2e since 2016, and the overall impact of Triangulum has been to increase university share of EVs in vehicle fleets from 5% to 25%, with reduced GHG emissions of over 125 tCO2e, 11kg NOx, and 70kg CO. 4 cargo bikes have made 4,493 journeys and travelled 6,697 km over a three year period and saved 820 kgCO2e. The Manchester-I data platform hosts 9 real time data feeds and has 4 organisational users and 307 users that have downloaded data 427 times. Over 50 people have attended the Innovation Challenges hosted in 2018 and 2019.

For Eindhoven, in Strijp-S, biomass and Sanergy have replaced the old heating system and provided 100% renewable energy for heating. In 2019, 14% of all energy was generated by Sanergy. 14 EV charging stations have been implemented. The fiber-optic network has been expanded extensively with 350 home connections and 7,050 office connections. 40 sensors have been installed in Strijp-S. 28 SMEs from the iCity tender have been created, and €50m p.a. additional investment has been secured from partners since 2016. In Eckart-Vaartbroek, for social housing, 11,200 m2 buildings have been renovated, reducing GHG emissions by 20%. The estimated energy bill reduction in 2019 was 55%. For the digital renovation platform of Woonconnect, 284 households (29%) used it, and 174 made a plan (scenario) for the renovation of their home. The Eindhoven open data platform has been viewed 96,000 times per month in 2019 and actively downloaded nearly 4,000 times per month.

For Stavanger, 56 smart gateways have been installed in residential buildings, and the Central Energy Plant (CEP) in Stavanger Commune has avoided a total of 500 tCO2 p.a. which represents an 87.5% reduction in CO2 emissions. 5 battery buses have been deployed by the bus operator in the city, avoiding 135 tCO2 and 250 kg CO. A design competition for the Battery buses has been effective in engaging the public and school children in the project. The Cloud Data Platform has 6 internal users, hosts 4 datasets, and currently has 35 completed impact indicators. It has been used to deliver data analytics to improve efficiencies at the local bus operator.

Project level Impacts

  • The main Energy sector impacts are reduced local energy use with more demand being met by renewable sources, reduced energy costs, and decreased greenhouse gas emissions. Across the project CO2 savings of more than 2000 tons have been achieved. Evidence from pilot work scaling potential benefits suggests that Triangulum interventions could reduce CO2 emissions across the Lighthouse Cities by 15% if they were rolled out across the city.
  • The main Mobility sector impacts are improvements in efficiency, and reduced greenhouse gas emissions (CO2, NOx, CO). The main impacts across the city relate to the demonstration of different types of EVs in diverse settings (bus fleets, corporate and municipal fleets, SMEs) that has proven positive user experiences and stimulated further uptake in the Lighthouse cities.
  • The main ICT sector impacts are increases in the availability of open data, data downloads, and improvements to fibre optic networks. The three data hubs have been used to deliver value to partners and in Eindhoven and Manchester will be continuing beyond the project end date through follow on funding.

City Level Impacts

1. Process learning

Triangulum has led the development of the ‘process learning’ concept, which describes how partner organisations have learnt to do things in new, smarter ways. These impacts are critical in the current context of zero-carbon cities and the need to accelerate transitions to sustainability. They describe a new ‘Triangulum’ way of governing cities.

  • Partners tended to anticipate technical and economic benefits from being involved in the project but found that the main benefits were related to relationships and networks, capacity building, and process learning
  • Early stage communication between project partners is essential to build relationships and encourage communication between sectors and across cities
  • Encouraging as much face to face interaction as possible is key to sharing learning and experiences in a meaningful way
  • Replication within cities is just as important and commendable as replication in other cities

Our survey and interviews with partners revealed three priority areas to enable smart transformation:

  1. Ensure enabling policies and planning are in place that address the specific barriers identified through the demonstrators in order to allow demonstrations to be deployed at scale.
  2. Integrate smart solutions into procurement and operating budgets to ensure they can be purchased at scale.
  3. Facilitate and incentivise peer-to-peer learning among implementers across different organisations (building managers, energy engineers, fleet managers) as early as possible to promote data sharing and the adoption of shared (i.e. connected) solutions.

2. Leveraged investments

Spin-off initiatives have been a major city level impact of Triangulum, and reflect the development of a deeper form of partnership working within the Lighthouse Cities.

Triangulum Spin-off

Summary of Lighthouse City Stavanger

Triangulum: «Five years of new experience, challenges and important goals”

With Stavanger as a Lighthouse City of Triangulum, the Stavanger region has developed new technology and interacted across the private and public sectors to cut CO₂ emissions, to create better transport and communication solutions, and to make energy use more efficient.

With the support of Kolumbus, Rogaland City Council has implemented emission-free electric buses in Stavanger, being the first in Norway. The City of Stavanger helped establish a central energy plant that uses heat from the city’s wastewater to produce energy. The University of Stavanger has developed a data hub that can process, analyze and visualize large amounts of data. Lyse AS has developed new technologies for energy efficiency and management that have been tested in 100 homes, a gym, and a nursing home. They have also developed Blink, a video system providing secure communication on different screens. Greater Stavanger has led the communication work to spread knowledge about these local projects nationally and internationally.

The participation in Triangulum has laid the groundwork for active public and industrial engagement regarding smart cities developments. As a result, Stavanger Smart Region, a network and regular meeting arena for the 13 municipalities in the Greater Stavanger region has been formed. It has also contributed to creating an internationally renowned conference and exhibition, the Nordic Edge, as well as a national cluster, other proposals and project networks.

The University of Stavanger has initiated an international cooperation on smart city technology called CityZEN. Also, the university has become a European University as part of the European Consortium of Innovative Universities (ECIU). The new ECIU University will be based on solving challenges offered by public and private sector actors. This pilot project will concentrate on challenges related to UN Sustainability goal #11 – sustainable cities and communities. The City of Stavanger is a partner and has confirmed that they will provide three challenges for ECIU learners to be solved.

Participation in Triangulum has also led to new EU-projects such as TrAM – an electric boat that is currently being built and will operate between Hommersåk and Stavanger. Being the first in Norway to implement buses running on battery power has led to increased attention on electric buses and emission-free public transport in our region, and a process of electrifying buses in urban areas is initiated. In 2020, 17 new electric buses will become part of the public transport system in Haugesund. In addition, the Kvitsøy ferry that will start in 2020 as well will run on power from a local onshore energy distribution network and a combination of biodiesel, biogas, and hydrogen.

Lyse AS’s solution Blink has been tested in two of Triangulum’s Follower Cities, Sabadell and Prague. “The aim is that, in the future, Blink will be a trusted communications tool for several different users, specifically within health care, but also for a wide range of other purposes,” says Per Fjeld, Senior Advisor at Lyse AS.

As a result of energy management tested in 100 homes, 10-20 of these will continue to use the smart panel and establish a customer-relationship with the Lyse AS brand Smartly.

Elnett 21 is another project that Lyse AS will be part of during the next couple of years. This project aims at creating an energy system of the future, exploiting flexibility between large energy users, which in this case are an airport, a harbor, and an industrial park. Lyse has also been able to contribute actively in another H2020 project called INVADE, developing future solutions for distributed storage and flexibility in the energy market.

The central energy plant will continue to be the primary source of energy for the city’s administrative buildings. To educate the citizens of Stavanger and other professionals interested in the energy plant, the city is creating an information board that illustrates how the central energy plant works. This board will be installed on the outside of the administrative buildings. It will contain a visible sign of Triangulum and the information will also be digitally available.

To further communicate the exciting projects and the results of Triangulum within Stavanger region, a web page has been developed where you can read more about each of the implementations mentioned and their respective outcomes:
