In The Bristol Cable, the English city’s specialist newspaper, an article by Neill Talbot proposes the city’s forestation and planting projects as examples of how to combat Bristol’s heat waves, also citing Boeri Studio’s Bosco Verticale.
The English city’s main problems are described as overheating in the summer due to poor ventilation, obsolete buildings and lack of shade from other buildings or trees.
In addition, with global warming Bristol’s temperatures have seen and will see an exponential rise which has led the council to study the One City plan, which aims to increase the city’s tree cover by 25% by 2035 and double it by 2046. The target is the planting of approximately 1.7 million trees – 80,000 of which have already been planted.
As an example of one of the methods for integrating more plants into the urban environment without excessive land consumption, the Bosco Verticale in Milan is presented, which houses on its façades vegetation equivalent to that of 30,000 square metres of forest and undergrowth, concentrated on 3,000 square metres of urban area.
The presence of trees and plants, in fact, contributes to a lowering of the temperature on the façade by about 30 degrees centigrade, and that in the flats by 2-3 degrees centigrade.
