Week 7 - Sustainable urban renewal: Royal Seaport in Sweden
In recent decades, as population and housing demand have grown, Stockholm is experiencing a new round of urban renewal. The newly planned urban construction areas mainly include abandoned freight train stations and ports for industrial and logistics. The Royal Harbour City renewal project focuses on environmental sustainability, economic sustainability, and social sustainability, and proposes sustainable development strategies for urban functions, transportation networks, and resource utilization.
Three specific indicators of the Royal Harbour City:
(1) Carbon dioxide emissions before 2020 will be less than 1.5t/person (average indicator is 4.5t/person)
(2) The maximum energy efficiency of newly built residential buildings is not higher than 55kW•h/m2
(3) Replace fossil energy with renewable energy by 2030 (Stockholm plans to achieve this goal by 2050)
The four design strategies include urban function, sustainable transportation, resource and energy, and urban green space system.
City function: Strengthen the connection between streets, parks, plazas and other public spaces in the city, show the characteristics of different regions and make the city more stable when faced with demand at different times. The ground floor space of Harbour City is as open as possible and will include a variety of dynamic and diverse businesses and events. In addition, the plan will pay more attention to the layout and design of facilities such as schools, bus stops, supermarkets, parks, etc., in order to facilitate the compounding of urban multi-functions and activate public spaces.
Traffic Context: Royal Harbour City tends to establish a convenient and green transportation context and promote the concept of green travel, radically reducing people's demand for transportation. Some high-intensive public facilities such as retail, services, schools are set at public transportation nodes. nearby. The clearly identifiable street structure not only adapts to future changes and the diversity of modes of transportation but also ensures the comfort and safety of the walking experience through humanized design. On the other hand, it encourages the use of electric cars and other green modes of travel by providing adequate charging stations, free ferries, and no fossil fuels. These convenient and green traffic links effectively connect the various functions of the city and increase the accessibility of each area.
Resource and energy: The treatment of water is concentrated in both sewage and rainwater treatment: the purpose of the sewage treatment system is to reduce the environmental impact on lakes and oceans, optimize the use of wastewater recovery, and return nutrients to the cultivated land through a closed-loop system. Rainwater is treated on-site without draining the drainage network and sewage treatment plant, filtering through rainwater gardens, floor drains, filtration devices, etc., effectively alleviating system operating pressure and load.
Greenland System: Royal Harbour City will create a healthy and resilient urban environment. By constructing a versatile green space system and incorporating horticultural design. It not only satisfies the needs of landscape leisure but also helps to create a healthy and happy ecosystem, which has a great improvement in environmental noise and air pollution. The newly developed waters will also integrate entertainment, transportation, ecology, and landscape.
Urban renewal is a long process and time is required as a test. Whether sustainability goals can be achieved ultimately and strategies can be implemented depends on the support and participation of multi-stakeholder groups.
