Abstract
In response to the growing demand for high-quality urban living environments, this research addresses the optimization of sky garden designs in mid-to-high-rise buildings, a topic that has not been thoroughly explored despite its potential for enhancing micro-environments. The primary aim of this study is to identify design strategies that maximize ecological benefits by evaluating a variety of sky garden configurations. Using Computational Fluid Dynamics (CFD), the study analyzed 96 different sky garden combinations, considering three building forms (square, rectangular, circular), four sky garden types (side, central, corner, peripheral), and four height levels (24, 44, 64, and 84 m). The simulations focused on key micro-climatic factors such as wind velocity and pressure, as well as heat effects from vegetation transpiration. Results indicate that square and rectangular buildings with central sky gardens at approximately 55 m provide significant environmental benefits, while circular buildings with peripheral sky gardens deliver the most optimal micro-climatic conditions across various heights and plant configurations. The key contribution of this research lies in establishing a basis for future design standards and regulations, offering a novel approach to maximizing the ecological and climatic advantages of sky gardens. This study's originality lies in its comprehensive evaluation of multiple design parameters and their combined impact on urban micro-climates, thereby providing valuable insights for architects and urban planners aiming to enhance urban sustainability and livability of mid-to-high-rise buildings.
