Green open space implementation on the underground building

Abstract

Green Open Space (GOS) as described as an open place to grow plants both naturally or intentionally planted. The arrangement of GOS on the underground building is of a similar type to the green roof design on buildings located at ground level. This is due to the similarity in the characteristics of the park on top of a building. Using a quantitative approach, the study presented the GOS visually, showed the area, the percentage of green plants, and the number of shade trees. This research used the model of Underground Gas Insulated Substation (GIS) as a representative of the underground building that can be further reviewed to be applied in DKI Jakarta. Underground GIS requires land in a natural environment but tries to maintain part of that environment with green space applied to the roof of the underground building. GOS is applied on the Underground GIS roof by implementing the intensive green roof. By considering public activity spaces and arranging vegetation layout, it is hoped that this Underground GIS can become a built environment that can reduce the ecological footprint, enhance benefits for the environment, and make the growth of urban space more sustainable and livable.
