Description
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.
At the same time, Stockholm is growing rapidly and sometimes faces the challenges of both keeping and developing its unique city character. A key priority is to ensure that it remains a sustainable city, while offering an attractive and inspiring living and working environment. The implementation and monitoring of all climate actions undertaken in the city is coordinated by the climate action group. Their long-term aim is to become completely fossil fuel free by 2040.
In this context, within the GrowSmarter project, Stockholm demonstrates 12 smart solutions in the fields of low energy districts, integrated infrastructure and sustainable urban mobility in Årsta, a fast-growing district in the south of the city.
Demo Site Expected Impact
* Detailed information regarding the technical and financial performance will be available at a later stage.
The demonstration site in Stockholm consists of three refurbished buildings with an overall gross floor area of 36 307 m².
The final energy demand of the site is reduced by 3333 MWh every year thanks to the refurbishment. According to SCIS calculations based on energy design data and the respective emission factors available, the primary energy savings go up to 4918 MWh/yr while the CO2 reduction amounts to 1187 tonnes every year.
