The Amsterdam Metropolitan Area is faced with the major task of making the city more climate-proof. By facilitating an innovative network of blue-green roofs, the aim is to optimize water management in the future and to reduce water and heat nuisance.
The HvA contributes to the project in various ways. Led by professor Willem van Winden, researchers from the Center of Expertise Urban Governance and Social Innovation map the organization and preconditions for successful realization and upscaling of blue-green roofs. An in-depth actor analysis is made in which the various parties involved and their roles are inventoried. This part of the research ultimately maps out the possibilities for scaling up. We also develop a cost-benefit analysis and investigate the role of residents and their involvement and how we can best involve residents in the realization and upscaling of the blue-green roofs.
Led by professor Jeroen Kluck, researchers from Urban Technlogy will examine the effect of blue-green roofs on the city. The possible positive effects of blue-green roofs on heat stress, quality of life, water drainage and air purity are being looked at with great interest, especially now that we are making several contiguous roofs blue-green in this project.
Why blue-green roofs?
The blue-green roofs have the advantage over green roofs that they can absorb much more water and therefore also evaporate moisture for longer during heat and drought. This keeps it cooler in the houses and the neighborhood. Also, more different types of plants can grow, increasing biodiversity. Innovative in this trial is the smart system with sensors, through which the roof retains or discharges water based on the weather forecast. The smart roofs are connected in a network, creating a new kind of water management at neighborhood and building level. During the construction process, we work integrally with various public and private parties and involve 1500 inhabitants from the four neighborhoods.
10,000 m2 of smart blue-green roofs will be constructed in four Amsterdam neighbourhoods: the Bellamybuurt, Geuzenveld, Oosterpark and Kattenburg. These locations were chosen because these neighborhoods have an increased risk of flooding and damage in the event of extreme rainfall and there are sufficient suitable roofs for housing association homes that need to be replaced.
RESILIO stands for 'Resilience nEtwork of Smart Innovative Climate-adapative Rooftops' and is a collaboration between the Municipality of Amsterdam, Waternet, Polderdak, Rooftop Revolution, HvA, VU, Stadgenoot, De Key and Consolidated. The RESILIO project is funded by the Urban Innovative Actions (UAI) Program of the European Union. The UIA program offers subsidies every year for innovative pilot projects on various themes.
