Green Roof Scorecard
Learn how your green roof setup can maximize its ecological and regenerative value.
Green Roof Scorecard
Score your green roof
In four short steps you'll describe your roof's build-up. We then calculate its regenerative score across biodiversity, health, climate and stormwater — and show where it can improve.
Score in action
Rates the on-site regenerative value of your roof — biodiversity, health, climate and stormwater.
Biodiversity Support
Biodiversity support
Habitats and stepping-stones for urban wildlife — food, shelter and nesting for pollinators and birds in otherwise fragmented cityscapes.
0 / 25
Health & Well-Being
Health & well-being
Physical and mental health benefits — thermal comfort, cleaner air, noise reduction and the biophilic effects of contact with nature.
0 / 25
Climate Moderation
Climate mitigation & adaptation
Carbon sequestration, passive cooling and on-site renewables, plus reduced urban heat-island effect and greater resilience.
0 / 25
Stormwater Attenuation
Stormwater attenuation
Retains and slows runoff through substrate storage and evapotranspiration, cutting peak flow, urban flooding and sewer overflows.
