Abstract：Under the impetus of China's"carbon emission reduction and carbon neutralization"strategic goals,this paper aims to establish a set of systematic design methods based on the theoretical framework of architectural typology.This approach addresses design challenges for contemporary large-scale exhibition buildings,which are caused by diversified functions,complicated traffic conditions,varied spaces,and ecological problems.Such methods provide theoretical support and practical pathways for the overall planning and optimization of complex exhibition buildings. In the initial research stage,the compatibility of architectural typology with research on exhibition buildings was verified through theoretical analysis.Literature concerning exhibition buildings,both domestic and international,was reviewed,and existing research shortages were identified,forming the study's research ideas and entry points. In the method derivation stage,the core components of exhibition buildings were sorted and classified into four categories:function,transportation,space,and ecology.Based on analysis of correlations among elements,two major design dimensions were disclosed:"function-transportation"integration and"space-ecology"cooperation.Next,types of exhibition buildings were analyzed from a three-level perspective of"regional city ↔planning group↔exhibition building"to extract typical exhibition building models across different scales.A case study was conducted,involving the creation and practice of the Pazhou Exhibition Hall of the Canton Fair from Liuhua Road,Phase Ⅰ to Phase Ⅳ,where the correlation dimension and type analysis of the two major elements were compared and verified.Additionally,a quantitative assessment of wind environment and ventilation efficiency was carried out using CFD numerical simulation. The systematic design method of the Pazhou Exhibition Hall of the Canton Fair consisted of two steps. Step 1:Element Correlation (1)Regarding the dimension of"function-transportation"integration,the design realized the integrated operation of exhibition,conference,and related supporting functions.It achieved high-efficiency interaction between the Pazhou Exhibition Hall and the urban transportation network through the separation of pedestrians and vehicles based on an internal circular driveway and Zhujiang walkways,alongside the three-dimensional connection of freight and pedestrian flow lines. (2)Regarding the dimension of"space-ecology"synergy,the design guided natural wind to form urban wind corridors based on a fishbone-shaped exhibition hall layout and transitional courtyards.It also achieved indoor-outdoor climate regulation through the mixed ventilation strategy of metal roofs and skylights. Step 2:Type Analysis (1)At the regional-city level,functional business status and urban spatial layout were optimized. (2)For planning groups,support for industrial business status and the public spatial system were developed. (3)The architectural level realized a flexible combination of exhibition halls and ecological-technological integration. The systematic design methods for exhibition buildings,based on architectural typology,not only inherit its advantages in extracting architectural forms and spatial orders,but also address the complex functional demands and climate challenges of large-scale exhibition buildings.The theoretical innovation and case validation in this study are significantly important for promoting systematic innovation in contemporary large-scale complex exhibition buildings,and for providing feasible strategies and pathways for the green,low-carbon design and maintenance of future exhibition buildings.
