Nature-Based Solutions for Cooling in High-Density Neighbourhoods in Shenzhen: A Case Study of Baishizhou

These days, high-density cities are facing growing challenges related to the urban heat island (UHI) effect. Greening can be a nature-based solution for UHI effect mitigation. This study aims evaluate potential of solutions improve living environments in Baishizhou, neighbourhood Shenzhen. An integrated 3D visualisation research method was proposed this study. Rhino 7, Grasshopper, and ENVI-met software were combined environment characteristics before after design, as well compare differences outdoor thermal comfort index building surface temperature. The greening design scenarios include adding trees, green roofs, facades. simulations ran 24 h during test period from 01:00 24:00 on 9 August 2019, which hottest day Baishizhou selected area environmental simulation. Results indicated that (1) vegetation has positive cooling effect, providing comfort, while shade “trees” provide significant effects hot days tropical subtropical climates; (2) roofs facades significantly affect
