Zaloa Azkorra, an agricultural engineer of the UPV/EHU-University of the Basque Country, is currently conducting some fascinating in-depth research at the University School of Mining and Public Works Engineering into the benefits provided by green walls. The researcher has concluded that walls comprising plants offer great potential for absorbing noise and could be used as acoustic insulation. Temperature & Acoustic Benefits The researcher is proposing that green walls be used in buildings, inside and outside, as they can improve the temperature and, what is more, they can achieve acoustic improvements. What is more, they are attractive and cool, said Azkorra. But she also admitted at the same time that having such systems is costly and that, what is more, the systems need to be improved. As Azkorra pointed out, apart from having plants on the walls, they have to be maintained and that is quite expensive . So right now she sees no alternative but to fit them in special buildings. Now
