A symphony in green and blue
De Doelen in Rotterdam (NL)
Water management is a central aspect of the renovation concept for the De Doelen cultural centre. Pluvia, the roof drainage system from Geberit, provides valuable support here.
Thunderous applause echoes through the large concert hall in De Doelen, the multifunctional cultural centre in Rotterdam. The Dutch Philharmonic Orchestra has just performed Tchaikovsky's Sixth. However, not all visitors are probably aware of this: It's not just the acoustics in the national monument De Doelen that have improved significantly since its renovation in 2020. Something truly fascinating is taking place above the heads of the concertgoers: the renovated roof of De Doelen is a prime example of sustainable water management.
Part of an international sustainability initiative
The renovation of De Doelen took place as part of the international “7 Square Endavour“ project. This international initiative at seven different locations around the world aims to make areas fit for the future and counteract the negative effects of urbanisation such as pollution, heat stress and flooding.
A roof in green and blue
The green and blue roof with terrace of De Doelen – specifically its water management system - is of central importance. Around the copper sides of the large concert hall, an area of more than 2500 m2 on the roof has been planted with 84 different species of native flowers, grasses and herbs. Five large insect hotels were even integrated. The green area is irrigated with rainwater. A 300 m3 water storage tank was installed on the roof for this purpose. This buffers the rainwater – also with the help of the Pluvia roof drainage system from Geberit.
Less flooding, better quality of life
The water management system not only helps to prevent flooding, the stored water also feeds the plants on the roof and the greenery helps to cool the building. The national heritage organisation is also happy: the roof design of De Doelen was agreed with the cultural heritage authority and shows that even a national monument can contribute to an improved urban quality of life after renovation.
