Green roofs offer a lot of benefits when used. They have several social, economic and environmental benefits to mention just a few, and are crucial in stormwater solutions. They even make huge positive contributions when it comes to issues which surround biodiversity, climate change, flooding and decreasing green space in urban areas. These are just some of the benefits. They also offer benefits depending on the class of the person being asked the benefits he enjoys from their use. Here are the major ecological benefits which are available to all that use green roofs.
Management of rainwater;
Immediate water runoff from a building roof can be lowered by as much as between 50% and 90% depending on the design and exact materials of the green roof. This reduction in turn greatly lowers drainage flow rates. The reduction in drainage flow rates on its own part enables the capacity of the rainwater management system to be conveniently decreased, thereby causing construction cost to reduce considerably.
Enhances the microclimate;
The surrounding air is greatly cooled and humidified by green roofs. This hence creates a quite beneficial microclimate within the immediate vicinity and area. It also enhances the micro climate in urban centers where green roofs are used for buildings. The so called “Heat Island” effect can be notably decreased with a coordinated urban green roof development. Green roof development supply and fixing has become one of the major stormwater services in many cities.
Binds toxic particles and dust;
Green roof vegetation greatly helps the process of filtering out smog particles and dust. Nitrates and all the other harmful materials in the air and rainfall are absorbed by the green roof’s plants and bound within the substrates they also contain.
Enhances noise protection;
Planted areas absorb much more sound than the quantity which hard surfaces do. They are natural insulators of sound. Green roofs decrease reflective sound by around 3 dB and also enhance the insulation of sound by up to 8 dB. This feature is quite effective for buildings which are situated near factories, airports and noisy nightclubs.
Offers natural bio-diverse habitats;
Landscaped green roofs make up for green spaces, which were sacrificed to develop and create buildings. Such landscaped roofs also offer natural habitats to wildlife. This helps quite well in returning nature back into major cities.
Green roofs make use of recyclable and recycled products very extensively. This ensures that a considerable volume of further valuable resources is saved. The drainage elements are produced using expanded polystyrene rigid foam, rubber and polythene as major components. Most rooftop garden system soils are created using humus and either one variation of mono clay material or the other. The most vital criterion should be the quality of the product. It should be tested by recognized research bodies or institutes.
These are the benefits this article has brought. There are so many others. Especially when viewed in the light of being one of the most effective stormwater solutions, so many benefits of green roofs can still be listed.
