HOT|COOL NO.4/16 - "From one generation..."


District heating is vital for the future District heating will be a key element of Albertslund’s energy systems in the future too, but fossil fuels are being phased out and green energy/electricity, particularly from wind turbines, is taking over. The future will be 4th generation DH: • We will see a switch from a few central heat producers to many decentralised heating and cooling providers using many different sources; geothermal energy from under the ground, heat from large heat pumps driven by electricity from wind turbines, and seasonal stored solar heat. The system is expected to be supplemented to some extent with heat from waste incineration and biomass, even after 2026.

• The energy market will change as buildings are better insulated and consume less heat. • There will be more low-temperature district heating, at 50- 55° C (better insulated buildings mean lower temperature demand). Political decision In line with this, Albertslund’s ‘Vision and Strategy’ states: “We have set ourselves the target of having CO2-neutral electricity and heat supplies by 2025. We aim to ensure that Albertslund Forsyning delivers low-temperature district heating only. We intend to work on strategic energy plans and exploit

the opportunities for sustainable local energy production. And we will work to develop the intelligent energy system – also known as the Smart Grid – as a means of providing a sustainable, economical and secure energy supply in Albertslund”. Albertslund is already well equipped for the energy systems of the future, thanks to the many initiatives taken in the district heating field and because a good many of the city’s homes have been renovated in recent years. Work is continuing to reduce the energy consumed for heating through themany initiatives in the municipality’s energy- saving action plan. In the coming years, these efforts will be directed at the residential and commercial properties that have the greatest need. The ‘Albertslund concept’ will be revitalised and, together with things like the ‘BedreBolig’ scheme, will support the renewal and modernisation of private residential and business districts. House and land prices in Albertslund are relatively low, so there is room to invest in modernising and energy-optimising private buildings. The municipal council has just decided that Albertslund should switch to low- temperature district heating by 2026 at the latest, in order to increase the scope for bringing renewable energy from e.g. wind turbines into the district heating network via heat pumps.
