The Swedish community of Falkenberg with 40.000 inhabitants is one of the leading and most ambitious municipalities regarding re-generative energy systems. Falkenberg aims to cut its energy consumption of 1/4 within the CONCERTO core area, by using different techniques of Energy Efficiency (EE) and new methods of clean energy production.
Växjö, a city with 64,200 inhabitants in the south of Sweden wants to free itself from fossil fuels by the year 2030. It has already taken big steps in the right direction, reducing its CO2 emissions from fossil fuels by 34 % from 1993-2009. Another objective is to reduce the energy use per capita by 15% between 2008 and 2015.
The NEED4B demonstration site in Sweden features two buildings, which represent pre-fabricated low-energy wooden framed villas of between 140 and 200 m2. The houses were manufactured beforehand and then assembled at the selected locations. One building was assembled in a new attractive residential area near Varberg and used as display house for a time. The second building of the same kind was assembled at a research facility in Borås and used as a full-scale test lab for energy-efficient technologies and construction details, with artificial user-behaviour loads.
The city of Helsingborg had adopted an ambitious climate action plan by which the city had already achieved 88 % CO2 emissions reductions (compared with the 1997 level) and a less than 20 % share of fossil fuel, the final goal being carbon neutrality, or even exporting carbon-neutral energy to neighbouring areas. With this aim, the NEXT-BUILDINGS project realised very low-energy buildings as the first phase of a huge and very ambitious 311 000 m2 ecodistrict development.
The E2REBUILD demonstration in Halmstad, Sweden is a multi-storey building from 1963 with the typical features of that period, such as a reinforced concrete load-bearing frame and facade elements. The building contains 91 apartments. The retrofit included a complete exchange of main pipes (water and sewage) as well as new kitchens and bathrooms, energy-efficient measures such as new, highly insulated windows, improved adjustments of control systems, new high performance extraction air, new outdoor air heat pumps and increased airtightness.
The Swedish demo site of the BEEM-UP project is located in Alingsås and known as Brogarden. The area consists of multi-dwelling buildings built in the period 1971 to 1973, comprising a total of 300 apartments, divided into 16 houses with 2 to 4 floors each. All apartments have a balcony or patio.
Sweden’s capital city, Stockholm, has been working on climate change mitigation and adaptation since the 1990s. The city is a real frontrunner with well implemented climate action plans and pioneering policies to ensure it meets its ambitious environmental targets. The carbon dioxide emissions have been cut by 25 % per citizen since 1990.
Växjö municipality, together with its inhabitants, businesses, organisations and university, are all working towards a better environment and a smaller carbon footprint. The city has high ambitions to make itself sustainable, energy-efficient, fossil fuel-free and with a large proportion of wooden buildings.
Lund (Sweden) is a medium-sized university city with a research-intensive industry. The town dates back a thousand years, but the number of inhabitants has grown largely during the last century and a great stock of the buildings from the 1960s and 1970s now needs retrofitting. Almost 90% of the heat demand in the city is supplied by district heating, and the hospital and some office buildings are connected to a district cooling network.
Gothenburg took part in the CELSIUS project with several fields of action focusing on the construction of 900 new apartments, which are to be connected to the district heating system and used as small short-term thermal storage, for connecting ships to the district heating system when docked in the harbour, and for feeding cold water from the river into the district cooling network.
The city of Malmö participated in the BUILDSMART project with the construction of four different types of new buildings – a hotel, office and two residential buildings – with a focus on their sustainability. The buildings are located in two areas of the city – Malmö Live, in central Malmö, and in the south-east part of the city, known as Hyllie.
Gothenburg is the second largest town in Sweden with 526.000 inhabitants. The city has changed since the 1970s from being an industrial city to also become a “knowledge city” with The University of Gothenburg, and Chalmers University of Technology. Gothenburg has a rich cultural life, but it is also one of the most segregated cities in Sweden. Social sustainability and integration is high on the cities agenda. The area of Hammarkullen is located in Angered, one of ten city districts in Gothenburg, northeast of downtown.
Gothenburg service providers, citizens and administrations work together to overcome urban sustainability challenges through a mix of open data, open innovation and public dialogue. The city’s IRIS solutions focus on testing innovative energy management and storage to achieve energy positive districts.
