Why this matters
Green roofs can be considered for stormwater, habitat, thermal performance and roof protection. Those benefits vary by climate, design and building.
What the evidence suggests
The original RS-related proposal modelled a rollout and financial benefit using research-period assumptions. Those values were not verified operational outcomes and are not presented here as current savings or corporate plans.
What it looks like in practice
A responsible feasibility study begins with structural capacity, waterproofing, access, maintenance, landlord consent and the site’s remaining use. Pilot measures should be selected before installation so benefits can be tested rather than assumed.
Practical next steps
Three things leaders can do now
Screen candidate sites for structural and lease constraints.
Choose a pilot with a clear baseline for runoff, maintenance and energy.
Compare the intervention with simpler alternatives before scaling.
Phull Insights Perspective
The view beneath the headline.
Green infrastructure deserves a place in estate planning, but the business case should be built at site level and tested against actual performance.
