A new artificial turf can cool itself by storing rainwater and using capillary action to reduce surface temperatures, providing a safer and more sustainable alternative for urban sports fields.
“Here we show that including a subsurface water storage and capillary irrigation system in artificial turf fields can lead to significantly lower surface temperatures compared to conventional artificial turf fields,” said first author Dr Marjolein van Huijgevoort, a hydrologist at KWR Water Research Institute. “With circular on-site water management below the field, a significant evaporative cooling effect is achieved.
Above the plots, temperatures also differed. “We found lower air temperatures 75cm above the cooled plots compared to conventional artificial turf fields, especially during the night,” said van Huijgevoort. “This is a first indication that the cooled plots contribute less to the urban heat island effect.”The cooling turf combines the advantages of artificial turf and natural grass: It is durable, keeps itself cool, and offers a healthy environment to play sports.
