AB - Bioclimatic design can effectively affect the environmental thermal comfort level through changing the surface of the study area. Using Zhengzhou Beach Park as a case study, the impact of three different bioclimatic design methods (changing pavement only, changing design only and changing both pavement and design) on outdoor thermal comfort, temperature, relative humidity, and wind speed under the ENVI-met model is quantitatively analysed. The results show that the three bioclimatic design schemes significantly affect the predicted mean vote of the site. The overall decrease in predicted mean vote average after pavement renovation pavement renovation is about 0.03, the overall increase in predicted mean vote average after design renovation design renovation is about 0.01, and the overall predicted mean vote average decrease after combined renovation is about 0.02. The relation among different predicted mean vote values and occupied areas under different bioclimatic design backgrounds is quantified, and the difference-value of climate index change were visualized for the first time. This study firstly uses a series of figures to show different trends of predicted mean vote and their area changes under the background of different transformation modes, which can effectively promote the refinement of the research on biological climate design.
