Build and designing green open space rooftop garden
To help prevent or reduce global warming effects, adding a green open space on the house rooftop with a rooftop garden maybe a good idea. Just not limited to house rooftop, open space rooftop garden also good to be built on building rooftop such as high rise building for hotel or office residence. Although the condition of the urban region largely filled by a high rise building, the designers including architects, and landscape architect must create a green open space to add plants that have been taken over when the building was constructed. By creating a garden on the building rooftop, high-rise buildings can still have a green open space, because there is space efficiency. Park on the roof garden is as an alternative reforestation to improve the quality of big city environmental health
Build rooftop garden or roof garden is not cheap and need structure and specific roof construction. Even for optimal results, the building construction which designed with rooftop garden must be planning and concept from the beginning before building was constructed. However, green open space rooftop garden investment to build it, can come back in a few years later, because the cost of electricity is reduced air conditioning, and building economic value added. For example project, a private hospital in Singapore succeeded in reducing electricity consumption by 50 percent, after making roof garden, although the roof garden is just a tomato plant which placed in the pot to cover the entire roof. Another advantage, the hospital did not have to buy tomatoes anymore.
In addition to the shade, the roof garden can also be used to absorb toxic gases. For example, bamboo or palm can absorb formaldehyde gas and gasoline. While the lily plant, in addition to absorb formaldehyde gas and gasoline, alcohol and acetone also absorbs the resulting paint and so forth. A vine also serves to absorb gases acetate, ammonia, and other gases. Because of this function, the vines have been used to park on the roof (roof garden) outside the country such as Singapore and Japan.
How to build rooftop garden? Before making a rooftop garden, for the first time we must consider the building construction itself. Is it designed to support the burden of growing media in the form of land and trees will be planted on it or not. Because the roof garden should be supported structure and strong roof construction. The existence roof garden will lead to increasing burden. Heap of soil and plants will add dead load, wind load, and additional water load on the building roof. The building must have a drainage system that works well.
If the type of plant shrubs to be planted, he take into account the roof load will increase about 650 kg/m2, in addition to live load according to activity on the roof garden. For example, 400 kg/m2 for sports, 500 kg/m2 to party and dance, and 250 kg/m2 for restaurants
