Studying the Effect of Blue-Green Infrastructure on Microclimate and Human Thermal Comfort in Melbourne’s Central Business District

Blue-green infrastructure (BGI) is defined as a strategically planned network of natural and semi-natural areas with other environmental features designed managed to deliver wide range ecosystem services, which include microclimate regulation enhanced human thermal comfort. While green widely known be capable mitigating the adverse effects urban heat island, effect blue regulate comfort still poorly understood. This study investigates several blue-green-infrastructure scenarios in central business district (CBD) Melbourne, Australia assess their on Three-dimensional microclimatic modelling software, ENVI-met, was used simulate Physiological equivalent temperature (PET) quantify level selected research areas. Ten different were simulated, included those based roofs, walls, trees, ponds fountains. The simulations suggest that roofs walls high-rise building environment have small reduction its surrounding area by up 0.47 °C 0.27 °C, respectively, there no noticeable improvement perception. tree-based decrease 0.93 improve perception from hot warm. Scenarios water bodies fountains 0.51 1.48 yet they cannot area. A deeper body has better compared shallow one. fountain scenario tends local could only felt within certain radius fountain.
