Effective natural ventilation reduces humidity, cools the space, and enhances thermal comfort. In light of the frequent ventilation issues in the Lingnan area, this research suggests a successful ventilation technique using Jiangmen’s “Yunshan Poetic” Moon Island houses as an example. With its symmetrical architectural layout of townhouses and its primary courtyard villa product, the community typifies the Lingnan area. First off, we discovered that the district’s average temperature is as high as 30.95 °C and its average humidity is as high as 83.592%RH using actual measurements and simulation of heat and humidity data. The district’s buildings’ issues with dampness, peeling walls, and substance mold are primarily caused by poor ventilation. Secondly, the PHOENICS program was used to provide efficient ventilation solutions for the following six aspects: external wind infusion organization, group orientation layout, planar grouping optimization, building façade combination, monolithic building openings, and indoor ventilation block. In order to determine if the technique is effective, the ventilation variables are compared before and after optimization using the Building Ventilation Effectiveness Test and Evaluation Criteria. The study concluded that the building’s architectural characteristics and the local climate have an impact on natural ventilation’s effectiveness. This serves as a guide for both the scientific layout development of future urban settlements and the optimization of ventilation of existing villa buildings in humid and hot areas.
Under the dual pressure of the large number of patients and the funding of expensive treatments, the established medical model is no longer able to meet the treatment needs of patients with cognitive disorders. Cognitive disorders cannot be cured, and the proposed MCI stage provides a window of opportunity for early intervention of the condition. Mild cognitive impairment (MCI) is a high-risk potential conversion state prior to a diagnosis of cognitive disorder, where the person still has the ability to live but with the presence of cognitive damage. The theory of environment-facilitated rehabilitation has begun to be applied to the study of cognitive disorders prevention, but its effectiveness and the drivers of its pathological characteristics remain unclear. In this paper, we explore spatial design strategies for the rehabilitation of patients with cognitive disorders based on the adaptability of pathological characteristics, and provide new ideas for spatial interventions to prevent the condition. Firstly, this paper constructs the relationship between behavioral characteristics (roaming), pathological characteristics (cognitive impairment), and environmental factors interacting with cognitive disorder patients. Second, the feasibility of spatial design to assist the rehabilitation of the condition was demonstrated by analyzing spatial accessibility, visual visibility, and walking distance using the environmental modification of Yuexiu Elderly Service Center in Guangzhou as an example. The study concludes that environmental influences to improve the quality of rehabilitation and cognitive function are effective, mainly in the improvement of spatial communication depth and care efficiency variables.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
