Many respiratory infectious diseases are believed to be transmitted from person to person through droplet nuclei in the air or contact with droplet-contaminated surfaces. Most studies related to droplet evaporation only focus on the evaporation process, without dividing the transmission routes of diseases caused by droplet evaporation. In this paper, the actual size of droplet nuclei was analyzed, and droplet evaporation and the changes in component content were predicted. Especially considering the dynamic effect of evaporation on droplets size change, a more realistic sedimentation model was established, and the probability of pathogen transmission through different routes and the corresponding droplet size distribution range were analyzed. The results showed that the size of droplet nuclei and the rate of the evaporation process together determined the time required for droplet evaporation. The number of droplets still suspended in the air after the end of evaporation is much higher than the number of droplets settling on the ground. In addition, the differences in component content during the evaporation process may affect the inactivation of pathogens in droplets. This study provided a reference for the prevention and control strategies of respiratory infectious diseases in indoor environments.

The energy efficiency and sustainability of existing buildings have become a critical concern in Algeria’s efforts to reduce energy consumption and mitigate environmental and economic impacts. To address this challenge, a systematic and effective decision-making method is required to select optimal building retrofit measures in alignment with Algeria’s 2030 energy strategy. In this study, we propose an innovative approach based on the Fuzzy Analytical Hierarchy Process (FAHP), a widely used multi-criteria decision-making method, to evaluate and prioritize different retrofit measures. The FAHP allows decision-makers to have a comprehensive framework for making informed choices by incorporating independently proposed economic, environmental and technical criteria. The results demonstrate the high significance of retrofit measures that enhance thermal insulation, with double glazing and roof insulation emerging as top priorities. Sensitivity analyses confirm the stability and robustness of the decision-making process. This approach offers valuable insights for policymakers and building professionals seeking to implement sustainable and energy-efficient retrofitting strategies in Algeria’s construction sector. By aligning with the country’s energy goals, this decision-making method contributes to achieving a more sustainable and environmentally responsible built environment.

The radiant systems come to the fore due to energy saving potential and good integration. The effect of different forms of cold surfaces on human thermal comfort is focused on its application. A novel natural convection-radiant evaporator for heat pumps was developed and its influence on thermal comfort was investigated. A numerical model of the chamber with the evaporator was established and verified with experimental results. Thermal comfort experiments were conducted in a climate chamber and the influence of its asymmetric and uneven cold radiation on the thermal comfort was investigated. Due to the limitation of PMV in uneven radiation situations, the revised predicted mean vote (RPMV) was proposed to assess the thermal comfort in asymmetric and uneven radiation environments based on experimental results. Based on RPMV, the influence of the surface area and temperature of the evaporator on thermal comfort was numerically analyzed. The results indicate that indoor air temperature and relative humidity, RPMV increase with the increase of plate temperature, but decrease with an increase in plate area. The most favourable indoor thermal comfort environment was obtained at an indoor air temperature of 28°C and relative humidity of 50%, which is 2°C higher than traditional air conditioning system.

The watershed is the earliest geographical unit of human activity and the tensest area in terms of human–land relations. Focussing solely on individual watershed spaces makes it difficult to comprehensively reflect and address complex human–land issues. For the complex processes of the origin, dissemination, communication and integration of civilisations, a more macroscopic scale is also needed for systematic understanding and analysis. The exchange and mutual learning amongst the Yellow River Basin, Yangtze River Basin and Grand Canal region promote the diversity and innovation of culture, making them the ‘typical containers’ of Chinese civilisation. Based on the uniqueness and correlation of regions such as the Yellow River Basin, Yangtze River Basin and Grand Canal, this study constructs the concept of a ‘Yellow-Canal-Yangtze’ watershed community, combining existing disciplinary advances and summarizing its spatial, temporal and elemental characteristics. This research is conducive to promoting the creative transformation and innovative development of excellent traditional culture, assisting in the protection of watershed cultural heritage systems and the governance of watershed ecosystems, and promoting regional coordinated and interconnected development.

Prior studies have attributed the heightened positive thermal response during summer to perceived control. The process through which perceived control is cultivated in the built environment has been scarcely explored. A field study was conducted in a dormitory building operating successively in natural ventilation and mixed-mode in the cold region of China. A total of 922 valid samples were obtained. The data analysis indicated that the building’s operation mode impacted both perceived control and its influencing factors. In natural ventilation mode, occupants perceived less control than in mixed-mode, and perceived control was shaped by both thermal stimulus and exercised control. Conversely, in mixed-mode, the occupants’ perceived control was solely influenced by exercised control. Reflecting on this result, this study is the first to suggest a method for determining ‘perceived effectiveness’ by assessing occupants’ thermal sensations and preferences. Only air conditioning was perceived as effective, amplifying occupants’ perceived control, while other controls diminished it. In mixed-mode, control combinations incorporating air conditioning were judged to have perceived effectiveness. On this basis, further combining psychological adaptation with behavioural adaptation, active and passive technology was used to play the role of behavioural adaptation, and the upper limit of acceptable temperature for occupants was increased to 31.1°C.

The concern about indoor air quality in various micro-environments has been on the rise as buildings are vulnerable to an array of contaminants generated from various sources. The study aims to investigate and highlight the pollutant sources and composition in middle-income residential spaces through a case study approach. With large migration from small towns and saturation of megacities, the middle-income population in tier-2 cities in India is on the rise, raising concern about the well-being of the dense urban population. It involves a careful selection of typical MIG housing to identify major pollution sources from outdoor and indoor environments. The focus lies in the findings stemming from continuous air quality monitoring of PM10, PM2.5, SO2, NO2, HCHO, TVOC, CO and C6H6 and an in-depth physio-chemical analysis facilitated by Fourier transform infrared (FTIR), Analytical Scanning Electron Microscope (A-SEM) and energy-dispersive X-ray (EDX) spectroscopy of settled household dust. Analysis unveiled indoor PM2.5 concentrations of 21.93 µg/m3, exceeding WHO standards, whereas, TVOC concentrations were higher indoors than outdoors. Stark disparities between indoor and outdoor dust compositions and sources were also observed. Despite limitations, it provides a portrait of middle-income housing conditions, offering insights for interventions and future research on indoor air quality challenges.

This study was carried out in a building located in Antalya in order to determine the optimum combinations of different levels of improvement and PV panel use in existing buildings in terms of energy saving and LCC. Within the framework of TS 825 Thermal Insulation Rules in Buildings, which is the national standard in Turkey, three different levels of insulation in walls, roofs, floors and windows and three different numbers of PV panels for energy production were determined. 18 different alternatives obtained using the orthogonal array for five factors with three levels analyzed have been made. In terms of energy savings, the scenario with the highest levels of insulation for walls, roofs, floors and windows and the use of 12 PV panels is the optimum combination that produces all of its energy needs and switches to surplus energy with +KW after consumption. In terms of LCC, the alternative with 12 PV panels, where wall, floor and windows are the highest and the roof is insulated at level 2, is the best combination. PV panel integration was found to be the most effective parameter in terms of energy savings and LCC.
