It is the vision of Carlsberg Properties to create a new sustainable district in Copenhagen with housing, shops and office buildings in harmony with the historical old buildings and the neighbouring districts.
In 2009 Carlsberg’s production moved to a new site in Fredericia, leaving a 330,000 m2 industrial site in Valby, Copenhagen open for development. It is the vision of Carlsberg Properties to create a new sustainable district in Copenhagen with housing, shops and office buildings in harmony with the historical old buildings and the neighbouring districts. Fully developed there will be a mix of 77,000 m2 renovated old buildings, 253,000 m2 new commercial buildings and 277,000 m2 new housing.
Carlsberg Properties has focus on sustainability in the planning:
- Carlsberg shall contribute to a positive social development of Copenhagen
- Economic resources for the infrastructure and buildings shall be minimized
- The energy supply shall be independent of fossil fuels in the long term
Therefore the infrastructure is carefully planned with respect to sustainability. Efficient public transport, good conditions for bikes, connection to the integrated low carbon district heating system in Copenhagen and low energy buildings.
Ramboll provides consultancy services for planning of the infrastructure. Due to the focus on energy supply, Carlsberg Properties asked Ramboll to analyze the sustainability of the integrated energy supply compared to building level energy supply.
The analysis includes life cycle costs for the supply of heating and electricity taking into account the costs of emissions. The electricity consumption contributes to the largest CO2 emission as electricity mainly will be produced by fossil fuel condensing plants.
How can Carlsberg generate own electricity based on RES? The analysis shows that the best strategy is to join the Copenhagen Climate Plan and invest in two 4 MW off shore wind turbines. This is several times cheaper than 13,000 small 1.5 kW turbines on the roofs or 270,000 m2 of solar cells. Besides it is better for the local environment.
How should Carlsberg provide the heat? Should it be individual ground source heat pumps or district heating? The analysis confirmed that the strategy of Carlsberg to join the Copenhagen Climate Plan, to connect all new buildings to the district heating, is the most sustainable. The total life cycle cost for Denmark, including all the environmental costs, are the lowest with district heating. Also the total costs for the local society of Carlsberg and Copenhagen are much lower. Thereby Carlsberg will support the city of Copenhagen being CO2 neutral in the most cost effective way to the benefit of the other heat consumers.
The analysis proves that joining the city infrastructure is most sustainable both regarding environment, resources and social responsibility.
