As a type of passive architectural structure, wall-mounted solar chimneys enhance the natural ventilation volume of a building’s interior, and maximize reductions in the building’s operational energy consumption. They are indispensable in the building’s energy conservation and emission reduction. Therefore, measuring the wall-mounted solar chimney’s flow characteristics and relevant index parameters is particularly important. This paper uses a combination of full-scale experiments and numerical simulation to conduct a detailed analysis of the wall-mounted solar chimney. Four different radiation models, namely DO (discrete ordinates), S2S (surface-to-surface), MC (Monte Carlo), and Rosseland are used for comparison, and the results of the numerical simulation are compared with the experimental data. The results show that the maximum turbulent viscosity of the fluid predicted by the S2S radiation model is higher than that of the MC and DO models by 16.87% and 8.44%, respectively. The errors of the DO radiation model in the midline and glass cover plate direction concerning the experimental results are only 0.33% and 0.15%, respectively. The mistakes of the MC radiation model in these two directions are 0.51% and 0.47%, respectively. The DO radiation model is more suitable in numerical simulation predictions related to the wall-mounted solar chimney.

With the development of the Global Sustainable Development Goals, urban communities are increasingly focusing on sustainable development and all-age health and well-being, and the aging level of China will reach 21.1% in 2024. The aging process is accelerating, and the problem of population aging is becoming more and more serious, so it is more and more necessary and urgent to study the aging of the public space environment in urban settlements. Based on the research data of Urumqi settlements, this study utilizes importance performance analysis to evaluate the performance and importance of the aging public space environment. The main criteria elements for aging are identified as function and space, traffic and streamlining, services and facilities, green landscape and microclimate, and subjective soft needs; and the key evaluation indicators for aging are further refined. The results show that the surrounding urban environment, activity space abundance, building quality, building environment, external spatial layout, internal transportation, facilities, management, aging facilities, elderly service facilities, landscape, microclimate, and cultural activities are the key elements that need to be improved in order to improve the aging of the public space environment of cold urban settlements.
