Description

Green building roof

Technical Field

The invention relates to the technical field of building structures, in particular to a green building roof.

Background

Cities are commonly referred to as urban heat islands. Cities are generally hotter than surrounding rural areas because they have less green space due to the large amount of buildings and artificial ground built in them. These surfaces tend to absorb and capture heat before it is radiated back into the surrounding environment, resulting in a phenomenon commonly referred to as the "urban heat island effect" which most cities have lost much of the green space on the ground as economies develop and land development continues to exacerbate. In order to mitigate the urban heat island effect, alternative spaces for vegetation need to be sought, and roof top greening is one of the ways to add additional green space to a built city to improve the living environment. This is a way to illuminate the colors of urban landscapes and allium fistulosum trees without requiring additional space, which is scarce in densely populated cities.

The existing green roof building mainly aims at the aspects of rainwater accumulation and vegetation planting, has single functionality, cannot make full use of rainwater, and realizes cyclic conversion.
