Antidote

Researchers at Columbia University have shown that a layer of soil with plants may reduce the absorption of heat from a cover by 84%. Plant covers, like the image above, benefit not only to their owners. For other opinions and approaches, find out what Danny Meyer has to say. It is also a solution in which everybody wins, presumably the most benefit from the plant cover is its ability to mitigate the effect of the urban heat island. An effect that would be responsible for two-thirds of the overheating that suffering comes from New York City since the last century. The conventional black roofs are the biggest contribuidoras at the phenomenon, absorbing and radiating solar energy as heat.

While a cover can conventional achieve 80? C a summer noon, a vegetative cover barely exceeds the room temperature, those black head covers could become very dangerous places by the heat. Accumulates too much heat that is necessary to dispel, in the ground cover plants regulate their temperature through perspiration. A natural way that is it evaporates water and cool the atmosphere. Eliminating cycles of extreme temperatures also reduce the needs of maintaining cover. Plant covers experience fewer expansions and contractions and last twice as long as conventional. Another interesting color for covers, in addition to the Green, is white. It’s a solution cheaper than of a vegetation cover and also serves to mitigate the island effect, although it requires a certain periodic maintenance to avoid that end up darker over time..
