The Climate Tile: Pilot project on Copenhagen sidewalk trials new climate adaption system for future cities

The Climate Tile, an innovative tile designed for urban spaces to hep catch and redirect 30% of the projected extra rainwater due to climate change, is preventing floods in a Copenhagen neighbourhood as part of a pilot project.

The tile, which has been in development by Danish startup Tredje Natur since 2014, was installed in Copenhagen’s Nørrebro neighbourhood last September, on a 50-metre-stretch in front of Cafe Heimdalsgade 22.

Designed to be used alongside or instead of existing sidewalks, The Climate Tiles are dotted with a system of holes, tunnels and ridges. These allow the water to be funneled into planted spaces alongside the pavement. The plants consume a substantial portion of the water, while the rest sinks into the soil.

The rest of the water from the sidewalks is led through holes in the tiles to a storage unit by integrated pipes. The unit can manage the water in connection to storage, delay, diversion and percolation. This way, the flow of water to sewers is reduced dramatically, preventing floods.

The aim of the pilot project is to see the tiles in action throughout the seasons and to collect data on how they manage different weather types, weight loads, and salting.

The Climate Tile pilot sidewalk not only contributes to the street’s climate adaptation, but it also adds further qualities in terms of trees and planting. According to Tredje Natur, The Climate Tile is a new scalable climate adaption system for future cities.

The Climate Tile reintroduces the natural water circuit in the existing cities by a simple process that manages the rainwater from the roof and sidewalks and ensures that the water runs to the right place e.g. to plant holes and water banks. It can catch and redirect 30% of the projected extra rainwater coming due to climate change, and thereby prevent overloads within the existing drainage infrastructure.

Flemming Rafn Thomsen, partner at Tredje Natur, said: “We are happy to be able to now demonstrate a scalable climate adaptation system. Beyond working 1% of the time when we have climate accelerated rain incidents, the solution furthermore creates value for the city the remaining 99%. We believe our streets are the bloodstreams of society where people meet and that the sidewalk is an underappreciated part of our infrastructure that holds great potential for future communities in our ever-growing cities.”
