The community Tweewaters is the largest innercity development in Belgium. It relates to the conversion of an industrial zone: 1.200 dwellings and offices will welcome 5.000 residents. City developer Ertzberg has defined a holistic, sustainability vision where all aspects woven into our society are considered: compact buildings (maximum integration of sustainable materials) with a footprint of 30%, car free squares and a public parc, green energy, waste management (weighted individually), waterrecycling, mobility alternatives (e-solex network), consumption & services (local offer of local goods).
The highly energy-efficient buildings decrease (-45%) their heat demand. The remaining energy needs are fulfilled with 100% green heat and power, locally produced (bio-CHP), distributed (local network) and supplied (demand response services at the dwelling level). The energy concept of the community reduces 82% of its primary energy consumption and results in the first CO2 negative quarter.
Tweewaters is a demonstration project participating in the FP7 program of the European Commission (for energy efficiency at a district level).
