Problems solved by technology

There are several problems associated with these current technologies.
This growing period results in increased maintenance costs, loss of growth medium from wind erosion and other natural forces, and delays the realization of benefits from the green roof.
Green roofs installed in this fashion are also typically permanent fixtures and, as such, render repairs to the underlying roof very expensive.
In addition to these problems, green roofs installed directly on the surface of a roof typically lack water retention means other than those inherent in the vegetation and growth medium.
This results in less efficient management of storm water runoff, as well as increasing the maintenance required by the green roof during dry seasons, such as watering.

Embodiment Construction

[0059] Reference is first made to FIGS. 1 and 2. FIG. 1 is a top view of a green roofing panel 100 according to the present invention. FIG. 2 is a cross-sectional view of a portion of panel 100 as viewed from the line 2-2. Panel 100 is shaped and sized in order to fit the area in which it is to be installed. Typically, panel 100 is rectangular having first sides 102 between 0.5 m and 100 m in length and second sides 104 between 0.5 m and 4 m in length. Panel 100 includes a carrier 108 and an anchor layer 106. Carrier 108 is formed of a web 110 with a plurality of water retention compartments 112 formed in web 110.

[0060] Typically, a system comprising several panels 100 is used to grow vegetation on the roof of a building. Vegetation is grown in anchor layer 106, and water retention compartments 112 serve to store water supplied to the system for consumption by vegetation.

[0061] As shown in FIGS. 1 and 2, anchor layer 106 is affixed to carrier 108. Anchor layer 106 can be affixed t...

Abstract

The present invention teaches apparatus, systems and methods for green roofing comprising interlocking and nesting panels on which vegetation can be grown before the system is installed. Systems may be installed on flat or pitched surfaces. The present invention also teaches apparatus, systems and methods for affixing green roofs to a roofing surface and apparatus, systems and methods for the irrigation of green roofs.

Description

FIELD OF THE INVENTION [0001] The present invention relates to the field of green roofing. More particularly, the invention relates to apparatus, systems and methods for green roofing. BACKGROUND OF THE INVENTION [0002] Green roofing involves the installation of green space on the rooftops of buildings and on other structures. A green roof extends the lifespan of traditional roofing materials, reduces building cooling and heating energy costs, manages storm water runoff, improves air quality, and creates a more esthetically pleasing environment. [0003] Notwithstanding the benefits of green roofing, there has been relatively little prior development in the field. A typical green roof includes a waterproof membrane disposed on the surface of a roof, a drainage layer comprising gravel or another suitable material, a filter membrane, growth medium that may be loose or contained, for example, in a mat made of rock wool, and vegetation such as herbs, grasses, mosses, wild plants and flowe...
