Poor indoor air quality reduces the comfort experienced in the environment and can also harm our physical health. Mechanical ventilation design plays an important role in improving the indoor environment and the safety of public toilets. Therefore, in this study, we aimed to evaluate public toilet ventilation design schemes through a digital twin to determine the most effective scheme for reducing indoor pollutant concentrations. In this study, we used Autodesk Revit to create a digital twin BIM of different ventilation systems. We simulated the diffusion of pollutants in these models using computational fluid dynamics (CFD)-based methods, and we used DesignBuilder to simulate building energy consumption. From the perspective of architectural design, we determined measures important for reducing the concentration of air pollutants by increasing the number and volume of air exchanges and controlling the installation height of exhaust vents. The results show that the ventilation design of an all-air air conditioning system with an exhaust height of 400 mm can remarkably improve the indoor environmental health and ventilation efficiency of public toilets, while consuming 20.4% less energy and reducing carbon emissions by 30,681 kg CO₂.

Medical facility equality is a critical metric for determining equal access to medical care. Their spatial distribution is important for effective pandemic treatment and daily prevention in cities. This paper used the Kernel Density Two-Step Floating Catchment Area (KD2SFCA) and shortest distance methods to calculate the accessibility of designated COVID-19 Fangcang hospitals and fever clinics in the Wuhan Metropolitan Development Zone. Their equality was evaluated by the Gini coefficient and Lorentz curve. Several results were obtained: (1) The facilities’ accessibility declines radial from the central to peripheral areas. (2) Most of the demand points in the study area can reach the medical facilities for COVID-19 pandemic treatment within 60 minutes. (3) For the spatial distribution of these facilities, the equality evaluated for different time thresholds differed significantly, with long time thresholds having better equality than for short time thresholds. (4) While the distances distribution of fever clinics is balanced, the equality gap in various areas remains enormous when considering population distribution. Suggestions for optimizing the spatial distribution of pandemic treatment medical facilities in Wuhan are proposed, and which will serve as references for the planning of Wuhan’s pandemic medical facilities in the future.

Background and Objectives: Social media has made online care facility reviews popular. By analyzing online reviews of nursing homes (NHs), managers and designers can acquire insight into the perceptions of the older adults and their families. This study aims to help improve the care and environment of NHs. Research Design and Methods: This study employed a mixed-methods approach to analyze online NH reviews. An inductive thematic analysis was utilized to identify and develop themes, followed by a detailed content analysis using Jieba, a Python-based program. Also, a regression analysis was conducted between the sentiment level of each subtheme and the final star ratings. Results: Online reviews of NHs could be classified into 6 main themes, 18 subthemes, and 53 initial themes. Among the main themes, “service quality” received the most reviews, followed by “physical space environment.” Of the 53 initial themes, “attitude and caring” received the most feedback, followed by “general impression of the space environment,” and “meals and nutrition.” Regression analysis using 18 subthemes revealed that, except for the “facility scale,” all 17 subthemes were significantly connected with the final star rating. “Personal and property security” had the highest regression coefficients, followed by “service attitude” and “space.” Discussion and Implications: Online reviews provide a valuable supplement to conventional NH quality assessment criteria, enhancing person-centered care delivery. Based on the findings, recommendations for NH management and design are proposed to improve care quality, environment, and satisfaction for older adults and families.
