Are you the one with blessings of green thumb? In fact, traditional parks are out of fashion now. Instead, you can use your abilities in planting on your roof. Of course, an approach that was first exercised in Germany is now developing in US that look for improving ecological issues such as greenhouse heating in city areas and hurricane water overflow. Undoubtedly, this is what green roof system do and even more.
What is the system of Green Roof?
The term green roof also denoted as eco roof, this is because its name suggests the meaning and that is raising plants on the roofs of houses. In the broader sense, it is related to changing traditional roofing material by an alive system of plants, fertilizer, and soil that is less in weight. Its aesthetic value is not the only thing it gives but also it forms a green layer at the top of your house and makes your living environment much better. In addition, the ecological advantages that happen in the vicinity, as studies have shown that green roofs decrease the expanse of maintaining roofs and also the energy by offering insulation to houses or buildings that covers them from high temperatures.
This technology is not fresh at all. Following many decades of placing it in to use, the Germans, who always feel that they are restricted for space, now they have modified this thought into a fine art. It is estimated that almost 10 percent of Germans have houses that have green roofs. Actually, nearly 350 million square feet in area of green roofs were placed in Germany between 1989 to 1999 and this fashion is still increasing.
What are the Utilizations and Benefits of Green Roof Systems?
In those areas where there is a blend of storm water and gutter systems due to heavy rainfall or storms, this happens when wastewater system gets overload and originating flood. As a result, raw sewage enters into the watercourses. It is seen that green roofs resist against the speed of storm water flow and decrease the whole speed of flow from the roof. Indeed, these roofs are capable of keeping almost 75 percent of the rainwater that is then discharge back slowly into the atmosphere by the processes of transpiration and condensation, whereas they hold back the toxins within the soil.
One more way of using green roofing systems is compacting with the high temperature island effect in city areas. Traditional houses soak up the radiation coming from the sun, re-emanating it has warmth that increases the temperature in urban areas to about 4 degrees Celsius, or 7 degrees Fahrenheit, more hot than the nearby areas around them. Nevertheless, the levels of heat on green roofs on warm days are almost 14 to 44 degrees Celsius, or 25 to 80 degrees Fahrenheit, much cooler than the traditional roofs in the neighborhood.
Additionally, green roofs make insulation in the roofs better from the installation place. The studies of environmentalists have shown that by using these roofs will result in the reduction of cooling needs by nearly 26 percent, and decreases the heat losses of winter season by almost 26 percent too. Furthermore, placing a green roof supports in increasing the lifetime of a roof as well by 2 to 3 times.
Finally, green roofs support in offering an environment for animals, plants, and other small creatures that typically do not have any place to live in the city areas. Therefore, it is proved that green roofs, at the top of 20 stories building still attract bees, birds and butterflies. They are also useful as sanctuaries for wandering birds, songbirds and many more that will be happy to find a place to live with natural environment.
