Furthermore, living roofs are one of the basic key factors for the successful development of moderate street flooding. Its system stores the water form rain, which is afterwards recycled for irrigation, allowing the drainage support the growing of various plants, where it is returned to the atmosphere through transpiration and evaporation. Currently, Germany, Switzerland and Austria live restricted by the law to allocate a living roof to reduce the threat of overflows of rain and extending the life of a city’s drain system.
Moreover, the shift from a monotonous, equal and repetitious city to a popular, natural and liveable one has its benefits. If many towns made current the green roofs, this will develop in mind the point of view of an ecological, liveable and environmental metropolitan. Therefore, numberless tourists and immigrants would arrive and immediately adore pleasantly the rooftop gardens, esteeming the sustainable planning the government had established to the city. Meanwhile, the city of Vancouver, located in British Columbia, Canada, has been well recognised worldwide in favour of their green roofs on the Olympic Village, the Vancouver Convention Centre and the Fairmont Waterfront Hotel.
Therefore, I urge you to conceive the idea of a sustainable planning using green roofs and liveable roofs; there is nothing to lose.
