To help prevent or reduce the pace of global warming, adding to the green open space with a garden on the roof of houses, buildings, hotels and offices is one effective way. Although the condition of the urban region largely filled by a high rise building, the designers (architects, and landscape architects) to create a green open space to add plants that had taken over when the building was constructed.
By creating a garden on the roof, high-rise buildings can still have a green open space, because there is space efficiency. Garden on the roof (roof garden) is as an alternative reforestation to improve the quality of the environmental health of a large city.

Making garden on the roof (roof garden) is not cheap and need structure and specific roof construction. Even for optimal results, the construction of the roof for the garden was designed from the beginning, before the building was constructed.

A private hospital in Singapore managed to reduce electricity consumption by 50 percent, after making a garden on the roof (roof garden).

While the lily plant, in addition to absorbing formaldehyde gas and gasoline, alcohol and acetone also absorb the resulting paint and so on. Vines also serves to absorb the gas acetate, ammonia and other gases. Because of this function, the vines have been used to park on the roof (roof garden) out of the country such as Singapore and Japan.
