The Application of Vertical Greening to Urban Rehabilitation and Maintenance

Abstract

Site greening is one of the nine indicators of green building in Taiwan. In built-up urban areas, buildings have been crowded without spare space for planting. Thus, encouraging residents planting perennial vine is a strategy which allows it to self-cling to the building surface or supporting structure so that the amount of green increases. It can reduce the building wall insolation and heat load thereby adapting indoor temperature, saving energy, purifying air, water, and soil, promoting urban ventilation, and reducing noise, and increase eco-efficiency. Taiwan has constructed neither vertical greening specification conforms to subtropical areas nor localized characteristics. The paper aims at exploring how to promote the application of vertical greening that increases green quantity as well as how to regulate maintenance of it in urban renovation. We believe we are benefited from it, and it helps to implement the ideal eco-city. Through the literature review and foresighted design point of view, the paper first introduces the relationship and development between vertical greening and green building and follows by the vertical green technology which increases green space and creates urban green network. Moreover, analyzing issues requires technology and innovation of vertical greening to apply urban rehabilitation and maintenance. At the end, it concludes: way of arranging plants in groups, natural irrigation, rainwater recycling system, reason why we encourage vertical greening, and need of amending the Special Chapter of Green Building Standard or providing Management and Maintenance Regulation of Vertical Greening.
