Urbanization of cities is creating lots of challenges. Because of the abundance of concrete and asphalt, flooding and heat stress are an increasingly prevalent problem. With more green spaces collecting the rainwater we can face this challenge, but space in the city is scarce. That’s why the RESILIO project is utilizing the unused space on the rooftops in inventive ways. The municipality of Amsterdam in collaboration with 8 partners is realizing 10.000 m2 of smart blue green roofs.

RESILIO is an acronym for Resilience nEtwork of Smart Innovative cLImate-adapative rOoftops’. RESILIO is a collaboration between the municipality of Amsterdam, Waternet, MetroPolder Company, Rooftop Revolution, HvA, VU, Stadgenoot, de Alliantie and De Key. The project is co-financed by the European Regional Development Fund through the Urban Innovative Actions Initiative. Read more about the partners.

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 through 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 develops business models for the innovative technology that is used in the project. Finally, the Public Health Service of Amsterdam (GGD Amsterdam) is conducting research on the health effects of vegetation. The knowledge and experience is shared with other European cities, so that blue-green roofs will be realized abroad as well and more flooding and heat stress as a result of climate change can be prevented.

Smart blue-green roofs


The RESILIO roofs are realized in five Amsterdam neighbourhoods: Kattenburg, Oosterparkbuurt, Indische Buurt, Slotermeer and Rivierenbuurt. These neighbourhoods have been selected because they have a high risk of flooding and damage during heavy rainfall (see the map by Rainproof). Moreover, the roofs of the selected buildings are in need of replacement, a good moment to implement sustainable solutions.

Most roofs are realized on social housing of housing associations De Key, Stadgenoot and the Alliantie. The tenants are informed about the plans and are involved with the project. Apart from the residents of the buildings, the entire city and its inhabitants profit from the blue-green roofs. And don’t forget the unobserved inhabitants: wild plants, insects and birds.

 “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.”
