November 22, 2018 – After the international Berlin Brandenburg Airport opens, the site of Berlin’s old Tegel Airport will be turned into a research and industry park for urban technologies as well as a residential development with over 5,000 homes. The heating and cooling systems will be developed by E.ON and the municipal utility Berliner Stadtwerke. The two companies formed a bidding consortium and created an innovative proposal which won them the concession in an EU-wide call for tenders.

They will supply the industrial park Berlin TXL – The Urban Tech Republic, as well as the Schuhmacher residential neighborhood, via a novel low-temperature network. Known as a LowEx network, it operates at temperatures as low as 40°C. As the operating temperature is lower than in conventional district heating networks, heat losses can be reduced, said E.ON and Berliner Stadtwerke in a press release. In addition, they said, consumers will be able to use heat pumps installed in their home or business premises to generate higher temperatures or cooling energy as needed. And the LowEx network will be able to take up surplus or self-generated energy, for example waste heat from production at the commercial and industrial facilities on-site, or energy from renewable sources, meaning that the customers will also be producers. The network will function as an energy exchange, with local and sustainable heat and cooling power produced – using a mix of CHP, solar installations, geothermal power and heat from waste water – then stored and consumed all on the same site.
