Review on Ventilation Efficiency and Planning of Urban Blocks in the Context of Carbon Neutrality

This paper analyzes and compares the research progress of urban block scale ventilation efficiency and planning at home and abroad in the past half century. This paper focuses on the study of the ventilation efficiency index of urban blocks and the comparative analysis of the existing research results on the correlation between the spatial form of urban blocks and ventilation efficiency, and summarizes and analyzes the wind environment characteristics of various low-carbon building layouts through numerical simulation and discussion under different low-carbon design techniques. To provide theoretical support for shaping low-carbon planning and design at block level from the perspective of carbon neutrality.
