Green Roof Technology Definition

Green roofs benefit the environment and local communities in many ways.

Green roof technology definition.

A vegetated landscape built up from a series of layers that are installed on a roof surface as loose laid or modular that is installed layer by layer on the roof or as pre prepared layers in trays green roofs are constructed for multiple reasons as spaces for people to use as architectural features to add value to property or to achieve particular environmental benefits for example stormwater capture and retention improved species diversity. Green roofs are also known as vegetative or eco roofs. Green roofs are also referred to as eco roofs oikosteges vegetated roofs living roofs greenroofs and vcp h 8 horizontal vegetated complex partitions. The term green roof may also be used to indicate roofs that use some form of green technology such as a cool roof a roof with solar thermal collectors or photovoltaic panels.

Although there are no precise definitions of them an extensive green roof has a shallow growing medium usually less than six inches with a modest roof load limited plant diversity minimal. They filter the air and water. They fall into three main categories extensive intensive and semi intensive. A green roof is a layer of vegetation planted over a waterproofing system that is installed on top of a flat or slightly sloped roof.

Green roofs last longer than conventional roofs reduce energy costs with natural insulation create peaceful retreats for people and animals and absorb storm water potentially lessening the need for complex and expensive drainage systems. These layers are identified as. A roof covered with vegetation designed for its aesthetic value and to optimize energy conservation. The roof deck with insulation and waterproofing protection and moisture storage layer.
