Pluvert

The Pluvert investigates the possibilities to integrate rainwater collected on rooftops to green facades and cool buildings, for example by evaporative cooling systems.

Year 2020-2022

Project type Research

What are the possibilities of harvesting rainwater from rooftops and use it to green and cool buildings in the city?

Rooftop surfaces make up a large part of the total surface area in the city and catch an enormous water volume of annual precipitation. As an alternative for rainwater drainage systems, the Pluvert distributes rainwater through innovative and low-energy techniques over different levels of a facade. In this way, water is buffered, recycled and used instead of directly drained. This increases the quality of the building’s exterior and the urban climate.

Plug-ins can be linked to the Pluvert and integrate rainwater to make buildings in the city adaptive to the problems they face regarding our changing climate. With more periods of drought and heat stress on the one hand and extreme weather events causing flooding on the other hand, buildings need to find a way to buffer water.

The Pluvert can facilitate green balconies and feed green facades through the passive distribution of rainwater. Plants integrated in the building's exterior can help mitigate the Urban Heat Island effect and cool down the temperature during summer. Other plug-ins use ceramic panels and evaporative cooling systems to increase the quality of the urban climate and save energy on air conditioning.
