HAMMARBY SJOSTASD - STOCKHOLM

​
The Sustainable City spans the area around Stockholm’s Hammarby sjö (Lake Hammarby), covering Södra Hammarbyhamnen as well as parts of Södermalm. By 2017, the district will have been expanded to include around 11,000 residences for over 25,000 inhabitants.
​
THE OLIMPIC VILLAGE DREAM
​
From the outset, the new district was envisaged to be an Olympic village. A new, sustainable district that could be developed across the somewhat run-down Hammarby harbour and industrial area, the potential existed to contribute towards the hosting of the 2004 Olympic games in Sweden.
Events took a different turn, but by then, the Sjöstad vision of an environmentally friendly inner city district providing modern housing for thousands of Stockholmers, was already in place.
DENSE GREEN/BLUE CITY DISTRICT
Hammarby sjöstad has been planned with a dense settlement structure with typically 4-5 story buildings in a compact neighbourhood outline, but with reasonably spacious green courtyards.
The moderate height of the houses and the sufficiently spacious neighbourhoods allow for both wind-shielded and sunny inner courtyards
There are also established green roofs which are an important part of the stormwater system as well as providing important habitat.
The area is, at a larger scale, linked to one of the green wedges – the Nacka Wedge with a large ski-slope, vast forests, small fields and several lakes
THE CLOSED LOOP MODEL
During the development of Sustainable City, the vision of a sustainable urban district was transformed into a detailed environmental programme. The ultimate objective was to reduce total environmental impact by 50%, in comparison to a typical area constructed at the start of the 1990s. However, more stringent environmental demands required a completely new set of solutions. This included a closed-loop system – the Hammarby model – with solutions for energy, waste, water and sewerage.

THE HAMMERBY MODEL
​
One new feature of the Eco-district, which has won international recognition, was to integrate several infra-systems in the planning. A strong feature is the system of interdisciplinary planning of physical flows of energy, water and waste.
​
The share of renewable energy was also intended to be considerably higher than the Swedish average – using bioenergy and incineration of local waste to produce both locally generated heat and co-generated electricity.
​
Large-scale local wastewater and storm water harvest and filtration were also implemented. Storm water devices have high aesthetical quality, which is an important factor in the liveability of the neighbourhood.

SUSTAINABLE MOBILITY AND INFRUSTRUCTURE
​
​
Hammarby sjöstad is the first district in half a century in which a tram-line was built as the main commuting traffic mode and the first tram-line ever which was outlined as a cross connection in the southern part of Stockholm.
Other features of the sustainable local transport system include an attractive pedestrian and bicycle network, a large carpooling system, a popular ferry connecting the Hammarby sjöstad with Stockholm Downtown’s South Island.
