A risk framework for blue-green roofs

The use of blue-green roofs is a stormwater management initiative that is expected to become significantly more common in the future, and the research-driven innovation centre Klima 2050 has prepared a framework for the prevention of building damage using such roofs. Many technical requirements must be met in order to deliver a robust roof construction. A blue-green roof must be planned to ensure that all such requirements are satisfied without making excessive compromises that may result in building damage because certain technical factors have not been taken into account. The successful coordination of the technical requirements needed, to deliver the best possible construction project, represents a major challenge. The framework described is the result of a PhD project conducted at the Klima 2050 Centre, and is now being used by centre user partners and other commercial organisations that are planning to build blue-green roofs.
