Hammarby sj\u00f6stad<\/a> (Hammarby Lake City) is an urban development project directly south of Stockholm\u2019s South Island. This is no doubt the most referenced and visited spot among Scandinavian examples of implemented eco-friendly urban developments. Hammarby is included in many publications, for example in the recent Ecological Design<\/a> by Nancy Rottle (2011). There are 13 000 visitors a year from all over the world.<\/p>\n

The original plan of Hammarby was to develop the former industrial area to an ecological sports arena and athlete\u2019s village \u2013 the aspiration was to develop this area for the Olympics 2012. When the bid was won by London the plans were changed and instead the Stockholm municipality \u2013 together with a number of construction companies \u2013 decided to make this the first Ecocity district in Stockholm for the first millennium. (The other was Western Harbour<\/a> in Malm\u00f6 which was displayed during the National Residential Fair 2001<\/i>). The district is developed around Hammarby Sj\u00f6 (Lake)<\/i> and when it is finished it will contain around 1 000 apartments for more than 26\u00a0000 inhabitants, with 6 m2<\/sup> work space\/inhabitant.<\/p>\n

The Hammarby model<\/strong><\/p>\n

One new feature of the Ecodistrict, which has won international recognition, was to integrate several infrasystems in the planning from the very beginning: technical infrastructure, mobility and communication infrastructure, building infrastructure and to some extent green-blue infrastructure. Another strong feature is the system of interdisciplinary planning of physical flows of energy, water and waste.\u00a0The Hammarby model <\/i>is today mimicked around the world \u2014 e.g. <\/i>in the Caofeidian Ecocity<\/a> development in China and in the Swedish SWECO consultant concept Symbiocity <\/i><\/a>in Brasil.<\/p>\n

The Hammarby model <\/i>includes energy conservation measures in which the goal is to reduce heat consumption by 50% and use electricity more efficiently compared to the Swedish average. The share of renewable energy <\/i>was also intended to be considerably higher than the Swedish average \u2013 using bioenergy and incineration of local waste to produce both locally generated heat and co-generated electricity. Large-scale local wastewater and stormwater harvest and filtration were also implemented. Stormwater devices have high aesthetical quality, which is an important factor in the livability of the neighborhood.<\/p>\n

One of the most famous features of the Hammarby model was the implementation of a high-tech waste sorting and waste transportation system, also linked to the local energy production in Stockholm. The most spectacular technical system is perhaps the vacuum waste suction system of various household waste functions (including, for example, burnable and compostable waste). In this system, which is implemented all over the district, filled waste bags are intermittently transported to sub-stations in the periphery of the district, which results in markedly efficient waste collection and no need for waste-lorries to enter the residential areas at all.<\/p>\n

A more sustainable mobility and communications infrastructure<\/strong><\/p>\n

Hammarby sj\u00f6stad 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 sj\u00f6stad with Stockholm Downtown\u2019s South Island.<\/p>\n

A dense green-blue city district with basically positive aesthetic qualities<\/strong><\/p>\n

Hammarby sj\u00f6stad 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 with ample possibilities and incentives to develop both inviting entrance green and common courtyard green, and facilitating small-scale cultivation in micro-garden plots or small greenhouses. 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 \u2013 the Nacka Wedge with a large ski-slope, vast forests, small fields and several lakes.<\/p>\n

Other district green areas of importance are the Luma-park, the Oak park and the Sj\u00f6stads parterre.\u00a0In Oak Park there are quite a few very old oaks trees which have the highest historical, ecological and aesthetical values.<\/p>\n

Hammarby sj\u00f6stad features many aesthetic qualities: the traffic planning has created a good soundscape with a low level of noise, allowing attractive sounds to enrich the residents\u2019 living environments. The first phases of the Lake City neighbourhoods are both wind protected and offer sunny courtyard and public space areas. The local areas in Hammarby are easy to keep clean, to maintain (e.g., green and blue elements) and the whole district has an attractive background fragrance due to lack of garbage, much green structure, soil surfaces, lake and designed streams.<\/p>\n

An evolving Sea City service structure<\/strong><\/p>\n

Slowly the commercial and municipal services are developing in Hammarby sj\u00f6stad. <\/i>From the beginning it featured a number of restaurants and caf\u00e9s, whereas the general stores where developed more slowly. This may have been an advantage as the expected wealthy senior population was not the dominant resident category in the Hammarby. Instead the sj\u00f6stad mainly attracted young families without or with one child. The result was an initial lack of stores for children and families, municipal services (schools and nurseries) and appropriate green areas. The sj\u00f6stads parterre<\/i> is an important common open space \u2013 even if it is mainly restricted to adjacent neighbourhoods and lacks several pedestrian path qualities with caf\u00e9s and shops.<\/p>\n

\"Pic26B\"Some weak points that need to be developed<\/strong><\/p>\n

Hammarby sj\u00f6stad lacks sufficient intermediary scale (district) green areas, which makes it important do develop \u201cleisure commuting\u201d both to the southern green wedge across the two ecoducts built over the main South link freeway and across the Hammarby lake to the South Island. The Lake City so far also lacks proper public squares for open space markets and an intense city life. It also still lacks a core centre and smaller local cultural centres with cinema, theater and music stages as well as public indoor meeting places. The apartment prices are rather high and there is a lack of affordable rental flats. The demographic structure is biased towards young families, which will create peaks of societal needs (daycare > schools > secondary schools > unqualified jobs). Also the cultural diversity is low and the area is highly income-segregated. The whole sustainability concept is challenged as long as the Hammarby sj\u00f6stad waste-food cycle is not better developed in micro-regional and local scales. The Hammarby could also strengthen its social cohesion in order to develop its sustainable lifestyle habits. Today the Lake City offers a more sustainable framework for everyday life compare to the average Swedish city but hardly challenges its inhabitants to lead a more resilient life.<\/p>\n
