Living Green Shell: Urban Micro-Vertical Farm

Abstract

In order to reduce the urban heat island effect and increase cooling insulation, certain innovative cities rely on the benefits of vertical greening system. However, finding the space in a highly- developed city such as Hong Kong and Taiwan is a significant challenge. Facing the same challenge, cities like New York, Tokyo and Singapore, develop vertical greening system such as green walls, green roof, or urban agriculture to maximize the greening capacity. However, the green-roof development in Taiwan faces the challenge of the unique culture of architectural additions, known as sheet metal housing. The roof-top sheet metal housing is commonly used in most of the Taiwanese communities and occupies the roof space. Moreover, this sheet metal not only limits the scale of greening development, it also increases the indoor temperature and energy consumption with its heat-transfer nature. According to the research, the Living Green Shell functions as shelter, cooling insulation, air purifier and helps improve cooling efficiency in conjunction with the concept of vertical farm. Through the BIM simulation evaluations, the research focuses on how the cooling insulation of the Living Green Shell (LGS) over the sheet metal buildings could give a better energy-saving efficiency. The micro-vertical farm system is evolving from LGS 1.0 to the final version, LGS 3.0 to improve related functions. The LGS also provides edible vegetables and produces solar energy via the mini-solar bites. With the sheet metal housing's easily fabricated nature, the housing could be integrated with the LGS devices and led to a broad implementation in Taiwan with proper promoting.
