Due to urbanization and dense populations, Taiwan has witnessed a stronger urban heat island effect than neighboring countries. A substantial body of research has shown that the vertical greening system used in modern architectures may be highly beneficial to heat insulation and reduction of indoor temperatures. Other recommendations include increasing urban green areas, reducing urban heat island effect, improving bio-diversity in cities, cleansing air quality and furnishing the façade of a city. Among vertical greening approaches, fabric gardening is a medium with many notable advantages, such as high durability, variety in design, and low maintenance. It is also environmentally friendly as it involves recycled materials. This paper focuses on the potential of fabric gardening to improve heat insulation in vertical greening systems. This study first conducts a simulated experiment to compare the cooling effects of fabric gardening versus other vertical greening systems. Then we conducted an on-site investigation in Chiayi Industry Innovation Center by twice measuring the building’s temperatures, each lasting for a week. Results indicate that the temperature of the indoor wall was on average 0.9℃lower than the atmospheric temperature at the fabric garden. The temperature difference between the atmospheric temperature and indoor wall was 10.5℃and 2.8℃, respectively. Heat transmission was reduced by 73%. This indicates that fabric gardening holds much potential for application in systems aimed at heat insulation and air temperature regulation.
