ABOUT RESILIO

There is more and heavier rainfall, but also more dry and warm periods. Because of the abundance of concrete and asphalt in the city we often experience flooding and heat stress. We need more greenery to collect the rainwater and keep the city cool. But space in the city is scarce. That is why Amsterdam is going to use the unused space of the rooftops in an inventive way. 10,000 m2 of smart blue-green roofs will be realized in the coming years.

WHERE
The roofs will be realized in five Amsterdam neighbourhoods: Kattenburg, Oosterpark, Indische Buurt, Slotermeer and Rivierenbuurt. These neighbourhoods have been selected because they have a high risk of flooding and damage during heavy rainfall (see Rainproof bottleneck map). Moreover, the roofs of housing corporations that participate in these neighbourhoods are in need of replacement.

Most roofs are realized on social housing of housing corporations De Key, Stadgenoot and the Alliantie. The tenants are informed about the plans and are involved in the project. Also homeowners can have a smart blue-green roof installed. From 2020, a subsidy from the municipality is available for this. Not only the residents of the buildings benefit from the advantages of blue-green roofs, but the entire city and its inhabitants. Also the unobserved inhabitants: many wild plants, insects and birds.

 

RESEARCH
The functioning and effectiveness of some blue-green roofs has already been investigated and scientifically proven with the Smartroof 2.0 project. With RESILIO, the roofs are realized on a larger scale for the first time and connected in a smart network. This offers many opportunities for new research. The Amsterdam University of Applied Sciences and VU University Amsterdam are measuring the effects on building, neighbourhood and city level. The HvA also are developing business models for innovative technology. Finally, the Public Health Service of Amsterdam (GGD Amsterdam) is conducting research to the health effects of vegetation. The knowledge and experience is shared with other European cities. In this way we hope that blue-green roofs will also be applied abroad to prevent flooding and heat stress as a result of climate change.

RESILIO is an acronym for Resilience nEtwork of Smart Innovative cLImate-adapative rOoftops’.

The project is a collaboration between the Municipality of Amsterdam, Waternet, MetroPolder Company, Rooftop Revolution, HvA, VU, Stadgenoot, de Alliantie, De Key and Consolidated.

The project is co-financed by the European Regional Development Fund through the Urban Innovative Actions Initiative.

 “It is important that we prepare ourselves for extreme weather as a result of climate change. With this project, we are able to use a large surface of the Amsterdam rooftops all at once. Also, I am very happy that because of this the people who do not own a house can enjoy the benefits of these rooftops.”

Councillor Ivens, Municipality of Amsterdam

“Water is a raw material. By disposing of it through a pipe, we turn it into waste. This is not right. Cities are becoming busier and the climate is changing, increasing the risk of flooding, heat stress and drought. This means that cities have to retain more rainwater for use during the dry periods.”

Friso Klapwijk, MetroPolder Company

“We show that you can make very precise arrangements about the amount of water that you are able to store on a roof, in such a way that a blue-green roof also gains economic value. This makes it relevant for us as water managers to think about how you can optimize that value for both the private and public domain.”

Kasper Spaan, Waternet

“We want to know what is of value to the residents. We have connected multiple roofs in a network and are letting them work together in the field of water management. This means that more stakeholders are involved and the role of good communication is becoming increasingly important.”

Jan Henk Tigelaar, Rooftop Revolution

“We are going to investigate the effect on the city. To what extent do these roofs cause less flooding? Are there positive effects on heat stress and quality of life? We want to specify this.”

Jeroen Kluck, HvA

“The power lies in linking data systems. We will link the information from the Dakota roof management system to Waternet data.”

Glen Bosman, Consolidated

“For the EU, the sharing of knowledge and lessons learned with other European cities is important. In this way, other cities can use the knowledge that is being developed by RESILIO about the technology, the process and the implementation of smart blue-green roofs.”
