Concrete Use Cases: Inspiring Successes

Real Estate Managers and Business Parks

Activity zones and real estate parks represent exceptional potential for collective self-consumption. With their vast rooftops and the diversity of their occupants (offices, SMEs, warehouses), these sites allow perfect complementarity between solar production and consumption. The sharing of installation and management costs makes these projects particularly economically attractive.

Greenbizz.energy: First Success in Business Zone

The Greenbizz.energy community, located on Dieudonné Lefèvre Street in Brussels (Laeken), is a perfect example of successful implementation in a business park. This pioneering initiative, approved by Brugel and winner of the BeCircular Award 2020, brings together 60 members (20 SMEs and 40 offices) who benefit from electricity produced by nearly 1,000 photovoltaic panels (240 kWp capacity).

Concrete results:
  • 203 MWh/year of shared renewable energy production
  • 75% collective self-consumption achieved
  • 50kW/120kWh battery for optimization
  • Charging stations for electric vehicles integrated
  • 25-30% reduction in energy bills
  • First project of this type validated in an economic activity zone in Brussels
  • Unique experimentation site with multi-technology innovation: solar + battery + electric mobility + passive building

Educational Sector and Communities

Schools and universities are ideal candidates for collective self-consumption. Their vast rooftops offer significant production potential, while their inactivity periods (school holidays, weekends) create substantial surpluses. By sharing this energy with surrounding neighborhoods or other communal buildings, these institutions can generate additional revenue while playing an exemplary pedagogical role in the energy transition.

Specific advantages:
  • Daytime consumption synchronized with solar production during school periods
  • Significant surpluses during school holidays to redistribute
  • Additional revenue to finance pedagogical projects
  • Educational value: awareness of students to energy issues
  • Community impact: supply to neighborhood families

Rural and Urban Communities

Local authorities have diversified real estate assets (schools, sports centers, administrations) offering numerous opportunities for collective self-consumption. In rural areas, the complementarity between public buildings and retirement homes creates particularly interesting synergies, with stable and predictable consumption profiles throughout the year.

City of Hannut - Smart City Prize 2022

The city of Hannut in Wallonia won the Smart City Prize 2022 for its first REC in Wallonia, developed in partnership with AIS'BAYE and WeSmart.
