IVM participates in the RESILIO project: smart blue-green roofs on Amsterdam social housing buildings

IVM takes part in an Amsterdam consortium that will receive 4.8 million Euro for the project RESILIO to lay out blue-green roofs in four city districts. The water carrying roofs are meant as a measure for climate adaptation and improvement of the biodiversity. By using sensors the roofs are smart and make micro-water management possible.

Green ànd blue
The blue-green roofs have an advantage over ordinary green roofs that they can absorb and store much more water while the plants continue to evaporate during heat and drought. As a result it stays cooler in the homes and neighbourhood and the houses and their surroundings are thus better protected against heavy rain, drought and heat. Also a wider variety of plants can be grown on these roofs which in turn increases the biodiversity. The roofs will be linked in a network regulating the water level on the basis of the weather forecast. When intense precipitation is expected, the storage is emptied beforehand so that the peak flow from roofs is reduced, limiting the discharge to the sewerage. The coming three years the smart blue-green roofs will be laid on 10,000 m2 roof of social housing buildings on four locations in Amsterdam: van de Bellamybuurt, Geuzenveld, Oosterpark and Kattenburg.

IVM
From IVM, Dr Ralph Lasage and Dr Hans de Moel (both from Water and Climate Risk) will be involved, as well as Dr Nicolien van der Grijp (Environmental Policy Analysis). IVM’s main contribution will be to assess the hydrological and ecological impacts of the pilots in the four selected city districts as well as the potential for upscaling city-wide. In addition, IVM will bring in its knowledge about participatory approaches and co-creation of knowledge, and conduct a societal cost-benefit analysis.

About RESILIO
RESILIO stands for ‘Resilience nEtwork of Smart Innovative cLImate-adapative rOoftops’, a collaboration between the City of Amsterdam, Waternet, Polderdak, Rooftop Revolution, Hogeschool van Amsterdam, Vrije Universiteit Amsterdam, Stadgenoot, Ymere, De Key and Consolidated. The RESILIO project receives a contribution from the UIA-programme (Urban Innovative Actions) of the European Union. Every year the UIA-programme offers subsidies for innovative pilot projects on various themes. RESILIO is a 3-year project, starting on 1 November 2018.
