GRO is the sustainability tool developed by the Flemish government, but now widely used on public projects to guide sustainable building and renovation. It evaluates key themes like energy, materials, water, mobility, and adaptability throughout a building’s life cycle.

GRO supports decision-making in each project phase - from design to use and eventual dismantling - ensuring long-term quality, resilience, and alignment with regional sustainability goals. It encourages integrated, context-aware choices for public buildings in Belgium.

SECO can support you in this and also make the link to the DNSH principle. These are essential for obtaining European subsidies applicable to public procurement.
