The successful project implementation was largely related to the development of effective project and partner management structures, including a platform for communication and exchange and the necessary decision-making and coordination bodies. All Lighthouse Cities have developed reference documents and plans for organising timescales, lead partners and budgets and managing the deliverables across tasks, including financial, technical and structural details from the implemented measures. Triangulum has successfully completed its monitoring and evaluation objectives and summarized its outcomes in a dedicated exploitation plan and an impact report.
In Manchester, it has been demonstrated that there is significant potential to make carbon savings and reduce energy demand. The interventions included optimising existing buildings using smart technology, demonstrating the potential to save 42,000t CO2 per year, installing new equipment in the form of solar PV and an energy storage system (saving €34,000 annually). A number of electric vehicles were deployed saving 20T CO2 along with four eCargo bikes, each making three journeys per day across the city. The vehicles have been monitored and the business case evaluated. The open data and service engine was developed by the University of Manchester and allows the connection for a range of data sources. The Manchester-I data platform hosts 13 real-time data feeds. It has four organisational users and 172 users that have downloaded data 189 times. A number of innovation challenges were held to engage local citizens with the data. Going forward, the platform will be further developed under the auspices of an urban observatory for the city.
In Eindhoven, the old heating system has been replaced by Sanergy, a biomass system providing 100% renewable energy for heating, generating 15.43% of all energy produced in Strijp-S. Also, 14 EV charging stations have been implemented and the fibre-optic network has been expanded extensively with 350 home and 7,050 office connections. The iCity tender has brought remarkable results and opportunities with 63 companies applying for the tender: 20 developed further their prototype and 8 got extra financing to bring them closer to the market. 50 Mio estimated additional investment to be secured from partners. In Eckart Vaartbroek, the renovated dwellings have contributed to reduce GHG emissions by 20.43%. A total of 11,200 m2 buildings (74 social housing units) have been refurbished within Triangulum with an estimated energy bill reduction of 55%. 284 people (28.6%) have made use of the digital renovation platform Woonconnect and 174 made a plan/scenario for the renovation of their home. The Eindhoven open data platform has been visited 96,000 and downloaded 4,000 times per month.
In Stavanger, the Central Energy Plant (CEP) prevents yearly 500 tCO2 emissions, an equivalent of 88% reduction and annual savings of €120,000. It also reduces 76% of energy for heating and cooling 20,000m2 having annual savings of € 240 000. The holistic CEP includes all RES, sewage, biogas, solar collectors and greywater recycling system. Stavanger aims to inspire other developers to consider sewage heating in their buildings. Smart gateways have been implemented in 100 homes, 56 successfully transferring data in the required period, reducing energy consumption by 26% and energy costs by 12%. E-buses have been utilised by the bus operator in the city, avoiding 135 tCO2, 250 kg CO and 66 kg NOx per year. The data analytics toolkit accessible through an access-controlled dashboard has six users and hosts four datasets. Blink, an innovative two-layer encryption WebRTC video solution, has the potential to save energy in terms of mobility and has successfully been replicated in the Follower Cities Prague and Sabadell, concentrated around usability in care environments with key elements being simplicity and safety for users.
