Use suitable roofs for energy generation and climate adaptation because roofs can serve several transition goals at once. They can produce electricity, retain water, reduce heat stress and improve biodiversity when the right roof type is matched to the right location.
In the Gelderland built-environment context, this turns roof space into strategic infrastructure. Solar panels, green roofs, water storage and insulation should not be planned separately where combinations are possible. The strongest value comes from matching technical suitability with neighbourhood climate risks and grid capacity.
