Heating the city - District heating and energy efficiency in houses
An increased market share for district heating and changes in district heating pro-duction have been one of the greatest contributors to greenhouse gas emission reductions in Stockholm.
50 years ago Stockholm initiated the bold project of building an infrastructure for the distribution of district heating. Today, district heating is produced by Fortum, and comprises nearly 80 per cent renewable fuel or energy from waste or residual heat. The district heating system covers nearly 80 per cent of Stockholm’s total heating needs.
The conversion from oil heating to district heating has reduced greenhouse gas emissions by 593,000 tonnes since 1990. This has also led to reductions in emissions of substances that are hazardous to health.
The city is supplied by four major production plants. The larger plants produce both electricity and heat, known as co-generation. One of the combined power and heating plants is the Högdalen plant, where the city’s waste is used for energy production. Heat in wastewater is also used for the production of district heating.
Come for a combined visit to Högdalen co-generation plant and the sustainable city district Hammarby Sjöstad:
- Learn about Stockholm’s climate work and its district heating system;
- Find out how the Southampton scheme can be used as a model for other municipalities developing local networks for decentralised energy and community heating;
- See how waste is being converted to heat and electricity;
- Listen to experiences from technological and political processes with passive houses in Frankfurt;
- Discuss energy efficiency in planned housing and how the refurbishment of apartment buildings from the 60s and 70s can minimize the energy consumption and create employment opportunities;
- Be guided through one of Stockholm's sustainable city districts.
Your hosts for this Deep Dive will be Jonas Tolf and Ulf Wikström.
