Artificial grass pitches often have negative connotations. The rubber grains may be harmful to your health, but also the heat that they retain and rebound receives a great deal of criticism. Last summer, the temperature above an artificial pitch in Leeuwarden hit 60°C, even though the thermometer at an adjacent natural grass field barely read 30°C.
Creating a cooling effect
This needs to be improved. That’s why, since the beginning of September 2019, researchers have been looking into how to create a cooling effect with artificial grass. Building 027 features four elevated test pitches: three with different types of artificial grass and one with natural grass. The artificial grass pitches feature the Permavoid system, the same technology that is used in the Smart Roof 2.0. elsewhere on the Marineterrein. This system helps to protect the pitches, as well as water and drain them. Rainwater is collected and stored under the pitch, which then evaporates through the artificial turf when it is hot, creating a cooling effect above the playing field and in the surroundings.
