Urban Farming Construction Model on the Vertical Building Envelope to Support the Green Buildings Development in Sleman, Indonesia

The purpose of this paper is to analyze the construction model of urban farming on vertical building envelopes to support the green building development in Sleman Regency, Special District Yogyakarta Province, Indonesia. The construction of vertical buildings in Sleman district is growing rapidly together with the increasing demand for the provision of housing and public facilities. The rapid physical development in Sleman has caused the reduction of green land such as green open space (RTH), agricultural land and rice fields. These developments potentially threaten food security in Sleman district. Urban farming is a method of agricultural activities to reduce the problems of agricultural land limitation in urban areas, like Sleman district. The construction design model of urban farming on the vertical building envelope is one aspect of green building that will support the efforts in vertical farming processes. This showed that the method did not require any horizontally ground space but effectively used the vertical space on the building envelope, including wall and building roof features and construction. In fact, the urban farming construction method will not only contribute to productive agricultural activities, but also support the greening of the urban area as well as reduce the crisis of agricultural land issues. The urban farming construction model of the vertical building facade includes the urban farming construction on the roof, wall, and balcony.
