Urban projects in Europe
Each of these projects is characterised by certain factors that make them special and therefore worth particular mention.
But they all have a common denominator: trees are the only air conditioner for outdoors!
Urban courtyards are what are known as heat islands. The air congests, heats up, and there is barely any in- or outflow.
Squares in the inner city often heat up. Asphalted and surrounded by tall buildings, they offer no shade, and the radiant heat is enormous.
A feature that is commonplace in Sweden is unfortunately still a rarity in German cities: newly planted trees have their trunks packed in a water bag.
Green roofs are the living alternative to the parasol.
Where planes used to take off and land, around 20,000 citizens now live surrounded by lots of, and above all large-scale, greenery.
