Hammarby Sjöstad is the first eco-city district in Stockholm. It is a 'town around a lake' where the planning work begun in the 1980s with an opportunity to expand the inner city of Stockholm. It is one of Stockholm's biggest urban development project and it focuses on water, energy and eco-friendly solutions. As a part of the ambition to create an eco-friendly city district, investments in e.g. green spaces, walkways and several large parks have been made. Furthermore, the Hammarby Model is the eco-cycle which describes environmental solutions used for energy, waste and water and sewage. It was established with a focus on 7 key areas: soil remediation, urban form, transportation, green buildings, energy, waste management, and water efficiency. (Ref. 1, 2, 11)

Focus

Creation of new green areas, Transformation of previously derelict areas

Project objectives

The goal of the project was laid out in seven key areas: soil remediation, urban form, transportation, green-buildings, energy, waste management, and water efficiency. “The goal of the entire environmental programme is to halve the total environmental impact in comparison with an area built in the early 1990s.” The goal for e.g. land usage include: “Sanitary redevelopment, reuse and transformation of old brownfield sites into attractive residential areas with beautiful parks and green public spaces.” Furthermore, objectives of the project include “Development of undeveloped green public spaces shall be compensated for in the form of biotopes that benefit the biological diversity in the immediate area, and natural areas of particular value shall be protected from development.” Also, green roofs are used (as a part of the local stormwater treatment) to collect, delay and evaporate rainwater. Also, the small and dense sedum plants form living green areas in the cityscape. The intention was to be "Twice as eco-friendly" with closed environmental loop and synergies between utilities, buildings, and users. (Ref. 4, 11)

Implementation activities

Hammarby Sjöstad is more than a new housing and commercial development: it represents a complete infrastructural project in which energy, water, transportation, and waste collection systems were designed to work together as an “eco-cycle,” what’s come to be known as the “Hammarby Model”. Furthermore “the Hammarby Sjöstad project office employed a new methodology whereby officials from the relevant administrations and authorities formed a unified management team.” Also, investments have been made in green public spaces (with maintenance plans for the oak forest, a reed park with wooden jetties, a broad avenue, and several large parks) in order to adapt the area to an environmentally friendly one. As mentioned, green roofs have been created (part of local storm water treatment, and forming living green areas). "Hammarby therefore promotes efficient environmental management, with low-carbon development, renewable energy and well-integrated public transportation. It also strongly supports climate change reduction and a sustainable energy future by promoting energy efficiency and renewable energy." (Ref. 1, 4, 11, 12).

Details on the roles of the organisations involved in the project

“All relevant administrations and authorities jointly planned the construction of the new city district. The municipality encouraged the builders (developers) to find their own solutions within the common frameworks, including eco-cycling, low energy consumption and energy production. The city then collaborated with developers and companies responsible for waste, energy, water and sewage and implemented the plan for the area.” (Ref. 5). “The City’s administrators and companies, municipal and private developers, the contractors and consultants are jointly responsible for realizing the objectives. Together, they form the group of actors or stakeholders of the development of Hammarby Sjostad.” Note that there is a "high degree of local authority leadership" due to "the fact that the City has acquired the majority of land in Hammarby Sjöstad.” (Ref. 6). The project " reveals the powerful role of strong public sector leadership in ensuring high quality development. In fact, the project was based and delivered through a process of state-led consensus integration between all parties and at all levels. A major result of this successful integrated planning approach is the Hammarby Model, which deals with energy, fresh water and waste". (Ref.12)
