Stockholm Royal Seaport

Smart City solution

Stockholm Royal Seaport is one of the largest urban development areas in Europe, with at least 12,000 new homes and 35,000 workplaces. The Development administration from the City of Stockholm started planning in the early 2000s. The new city district will be fully developed around 2030 and 2500 households have already moved in. The smart city district starts with a common vision in smart planning and design, where IoT is a tool.

Smart city solutions are:

  • Large-scale net-zero houses and locally produced solar energy. Energy performance is 40 % lower than national legislation. Actual PVs production: 1 GWh/year.
  • Multi-functional green structure to enable ecosystem services (5,5 ha parks, 13.500 m2 green roofs, 29.500 m2 court-yards).
  • Public spaces as meeting places. Street spaces for pedestrians, cyclists and public transport with appropriate infrastructure for electrical vehicles, car pools and bicycle parking.
  • Automated waste system for plastics, newspaper and household waste
  • Requirements on energy, waste and transportation are reducing green house gas emissions by about 60 %.
  • Capacity building (2.000 within the construction sector and 30.000 visitors).
  • Sound and socially sustainable built-in materials
  • Centralized construction consolidation centre reached a co-loading effect of 60 %.
  • Early dialogue and consultation with residents and companies
  • Sustainable Kid`s Forum attracted around 2.000 children for dialogue
  • Digitalised monitoring and feedback-processes established.
  • Triple and quadruple helix R&D projects (e.g. IoT, visualisation, circular economy)
  • Testing of innovation procurement and competition (e.g. construction consolidation centre, pop-up reuse center)
