Be.SHARE - Brussels Sustainable Heating and Renewable Energy community

Energy transition

Ongoing

Be.SHARE will test a local, low-temperature Carbon Neutral Heating and Cooling Network for the Brussels North District – a dense urban neighbourhood characterised by a mix of high-rise offices and fragile neighbourhoods with social housing. The network will harvest renewable energy under the public domain – geothermal units beneath parks and roads, and heat recovery from wastewater (riothermal technology) – and directly exchange energy between office and residential users with very different heating and cooling needs. A Public-Private-Community governance model ensures collaboration between public and private actors, academics and grassroots organisations.

Our main challenges...

  • Most buildings in the energetically and urbanistically dense Brussels North District use fossil fuel (natural gas) for heating, contributing to high carbon emissions and low air quality.

  • Individual buildings lack access to the ground to benefit from geothermal or other forms of renewable energy on their own plot.

  • Legal and operational barriers exist to harvesting thermal energy from the public domain.

and proposed solutions

  • A Carbon Neutral Heating and Cooling Network – based on advanced technologies and a double loop network – to enable exchange of thermal energy between buildings with complementary needs.

  • Exploitation of local renewable energy sources under the public domain: geothermal wells under parks and roads, and upscaling of a patented Riothermal installation in the local sewage collector.

  • A Public-Private-Community Governance model engaging public utilities, private experts, academics and grassroots organisations, which will engage 331 low-income households in the CNHCN’s design, empowering them to participate in their own energy transition.
