Western Harbour, previously a run-down shipyard and industry area of 187 hectares, is today a vivid “city within a city” with a university, ~10,000 inhabitants and more than 16,000 people working (2016). The area has its own systems for managing its energy supply and waste treatment. Car traffic in the area has been minimized as an environmentally friendly approach to urban planning and mobility.
Following the European Housing Expo of 2001 a team of international architects designed the Bo01 district in the Western Harbour of Malmö focused on “sustainability” in the broadest sense possible. This “city within a city” has its own systems for managing its energy supply and waste treatment. Car traffic in the area has been minimized as an environmentally friendly approach to urban planning and mobility. There are also green roofs on a significant number of buildings with a variety of plants in different colours depending on the season and extensive rain-water run-off systems. Visitors can witness the successful transformation of a previously decaying industrial area into an exciting and sustainable urban environment.
The Aktern heat pump plant forms the core of the energy system. This technology involves the production of heating and cooling with a large heat-pump. The energy is then stored seasonally in natural aquifers below 90-meter deep wells. The electricity needed to power the heat pumps is produced via a local 2 MW wind power plant that also supplies 1,000 flats with electricity. 1,400 m2 of solar collectors are mounted on roofs and walls of buildings in the district, which contribute 15 % of the total heating requirements. The 120 m2 of solar cells used for electricity generation is also a part of the renewable energy system. Modern systems for the collection of different fractions of household waste have been put in place in order to facilitate efficient waste management.
