Towards Eco-Vitality Pedestrian Street: Research on the Design of Traditional Commercial Street Oriented by Green Energy and Thermal Comfort

Abstract

This paper attempts to take the thermal comfort model and the concept of green energy conservation as a new perspective to study the traditional commercial pedestrian street, trying to make the transformation of the traditional pedestrian street achieve the goal of ideal comfort, taking the traditional West Street in Jiading District of Shanghai as an example. Firstly, through cases study of traditional commercial streets in southern China, the traditional wisdom of vernacular buildings and spaces in responding to regional climate is analysed in detail. Secondly, according to the detailed information of the project, combined with the field thermal imaging survey, the performance of simplified models of different spaces is simulated by dynamic simulation tools (such as Ladybug, Honeybee and Butterfly based on Rhino-Grasshopper). The multi-objective performance simulation optimization aims at thermal comfort, wind and sunshine environment, and compares thermal comfort at different spatial levels and at different times. Considering the thermal comfort and activities of commercial streets in the research project, it is found that there will be great differences in thermal comfort performance under different space forms, and the micro-environment design will effectively improve the comfort of the area, which is conducive to creating an eco-friendly and lively street environment.
