AIGC Creative Design Research on Architectural Facade Graphics of Macao Historical Urban area Based on Catalyst Theory

Based on ​the Urban Catalyst Theory, this paper explores how to activate ​the Macao Historical Urban Area by ​integrating digital technologies such as ​Artificial Intelligence-Generated Content (AIGC) and ​the Macau tourism image as intangible catalyst elements, ​with a focus on 22 building facades ​within the area. Through collecting thermal map data ​from the Macao Historical Urban Area during tourism peak periods, ​six samples ​exhibiting higher tourist attention were selected as creative subjects. ​Using the affinity diagram method, ​we categorized keywords related to Macao's urban tourism image ​and compiled them into an AIGC prompt dictionary. We employed AIGC design tools to develop a comprehensive workflow for the creative design of facades in the Macao Historical Urban Area. ​Through iterative testing and optimization, this workflow ​was implemented to establish a set of innovative design methods ​for the area's historical buildings. The integration of AIGC tools ​expanded creative design possibilities ​for the Macao Historical Urban Area, ​while the incorporation of tourism imagery ​enhanced the appeal of interactive tourism experiences. ​Furthermore, digital technology significantly ​improved design efficiency, ​and the proposed workflow ​offers a transferable methodology for the creative design of other historical buildings.
