Greenroofs.com – You may be asking yourself, “I know about green roofs but where is this blue coming from?” Blue-green roofs provide a higher water retention capacity, allowing them to release evaporation for a longer length of time during hot, dry weather.
Designed to store excessive rainwater in the event of heavy showers, a smart valve can gradually discharge excess rainwater based on real-time weather forecasts. On hot summer days, the rainwater and the plants are used to cool the blue-green roofs and the environment.
