Folk residence in the cold region of Northeast China is an integral part of China’s traditional folk residence, with significant geographical representation. In this paper, we take the residential compounds of villages and towns in the cold region of Northeast China as the research object, summarize four typical layout forms of residential compounds of villages and towns in the cold region of Northeast China, simulate the wind environment of combinations of different layout forms in winter using the computer numerical simulation software Fluent, and then analyze and evaluate the wind environment of the compounds, including the evaluation standard of the wind speed ratio and considering the area of wind shadows, number of vortices, and other factors.

The Ministry of Housing and Urban-Rural Development of the PRC has established more than 400 characteristic towns within two years, and these towns are developing rapidly as an important economic carrier. Due to its special layout structure, that is, the industrial area is closely related to the residential area, and the acoustic environment of characteristic industrial towns is diverse and complex. In this study, with reference to morphological parameters, the Cadna/A acoustic environment simulation technology was used to discuss the influences of structural forms of various building communityes in the town area on the noise changes of characteristic industrial towns based on factors such as distance and angle. The results show that the structure and form of the building community are closely related to the noise distribution of the towns. Based on this, corresponding planning strategies for optimizing the acoustic environment of industrial towns were proposed in this study.

As people's understanding of digitalization technology gradually deepens, digitalization technology has been widely used in the field of architectural design. The application of digitalization technology in architectural design is mainly reflected in its ability to visualize creative ideas, so as to provide designers with more effective references and thoughts, and significantly improve the level of architectural design. This paper focuses on the exploration of related problems about the application of digitalization technology in architectural design, which is of great significance to the development of China's modern architecture industry.

After half a century of development, green buildings have gradually formed a relatively sophisticated system. Based on the development status of green buildings and the climatic characteristics of cold region cities, the paper analyses the key technologies applicable to cold region cities in combination with actual projects, and provides a theoretical and applied basis for promoting the sustainable development of green buildings in severe cold regions.
