The project brings together the cities of Barcelona, Cologne and Stockholm to demonstrate 12 smart, integrated solutions for city services such as renovation, heating, waste management, mobility and other, as a way of preparing for a wider market rollout. All the smart solutions are fit into the "Lighthouse cities" strategic development plans and the "Follower cities" replication plans. The solutions will involve five "Follower cities" and other European and international study groups.
The solutions solve common urban challenges such as:
• the renewal of existing buildings by demonstrating the cost efficient refurbishment of 100.000 square meters of nearly zero or low energy districts reducing energy demand by 70-90%;
• integrated infrastructures for ICT, street lighting, smart grids district heating and smarter waste handling;
• sustainable urban mobility for both passenger and gods integrated in smart grids, biofuels from household waste thus reducing local air quality emissions by 60%.
