Rooftop gardens and Panels
Transcript of Rooftop gardens and Panels
The rooftop gardens slow down runoff by texturing. This is done by designing the positing of the different plants and making sure that the soil is strong and deep. This aspect will enhance the amount of water absorbed. The rooftop gardens will gradually use the water as their fuel but will also direct the water to resevoirs and cisterns for later needs. Different designs will have different effects, but if the soil is very deep-seated, the outflow of heavy rainfall will be completely consumed. Another great aspect to rooftop gardens is their ability of cleaning dirty air. Plants use their ability of photosynthesis to convert Co2 to oxygen. If these gardens are kept healthy, a 10m2 area of a rooftop garden consumes the same amount of Co2 as a 4 meter tree does in one year. This function can improve living standard for many people. It has been shown that cleaner air can increase ones blood oxygen. It can also enhances ones resperatory system, and can give a reduce incodence of headaches, eye irretation and asthma. But of course the most important impact is that it will reduce Co2 emissions. If alot were installed throughout citys, the amount of Co2 released by cars and buildings could be reduced tremendously. So I bet that your thinking to yourself; What the heck
is a rooftop garden? Well that is a really good question.
A rooftop garden is when you create a garden full of plants in an urban or suburban habitat on top of a building. These gardens are extremly beneficial to the climate converting co2 into oxygen. Another product like rooftop gardens are garden panels. These are placed on the side of buildings and have the same effect as rooftop gardens. Both these products can be designed to look really nice, and could easily become and alternative to advertisments. Rooftop gardens can pretty much be built on all kinds of surfaces and slopes. The structure of the garden is very strong and require less maintenace than normal roofs. Before creating rooftop gardens it is best to insure that your building isnt listed. This means protected by the goverment because of cultural heritage, special architect and enviromental value. Listing is a major problem towards rooftop gardens and is the reason that rooftop gardens aren't spreading as rapidly as they should. Urban heat island affect is another huge problem in big citys today. During the summer when
the weather is at it hottest dark-coloured rooftops, pavements and surfaces absorb and radiate heat from the sun. These high temperatures create a dangerous gas which not only theatens human health but also the enviornment. Rooftop gardens help to reduce this affect by increasing the amount of evaporation in the city. Many citys are plane concret and dark-colored pavements which dont contain the water needed for evaporation. The plants will use the water collected from rain to reduce the temperatures and smog. The evaporation from the plants will also reduce the amount of Ac needed in buildings. This will again show an effect on the climate but also money whise. You can in some way say that these rooftop gardens act as natural cooling agents. This should be the future A place which shows how benefitial rooftop gardens is on chicago's city hall. It was first created as a demonstration project, part of the citys urban heat island affect initiative. Chicago's first intention was too test the benefits of green roofs and their affect on temperature and air quality. The gardens consists of 20,000 of more than 100 species. The plants were selected to withstand the conditions on the roof, which is exposed to sun and can be windy and dry. A lot are prarie plants native to the chicago region. Chicago is now North americas leading green roof city.
