Summary: The home environment and sick building syndrome (SBS) symptoms in five southern Chinese cities have been studied over time. The study found a decrease in asthma prevalence and an increase in allergic rhinitis. Cockroaches, rats, mice, mosquitoes or flies were identified as consistent biological risk factors for SBS symptoms, while redecoration, buying new furniture, and traffic air pollution were identified as other risk factors.

Summary: The development of underground space can help cities solve land and space demand issues, but there are still many problems to be solved. This study investigates the differences in the comfort of lighting and thermal environment, work performance, and SBS symptoms among people living in underground spaces for long and short periods. The results provide optimal temperature and illuminance ranges for balancing these aspects and contribute to creating healthy and comfortable indoor environments in shared underground building spaces.

Summary: This study aimed to explore the relationship between sick building syndrome (SBS) symptoms of store workers in underground shopping districts (USDs) and subjective-objective indoor air quality (IAQ). Findings revealed a correlation between SBS symptoms and concentrations of aldehydes and volatile organic compounds (VOCs) in the USD stores. Therefore, controlling the chemical levels in USD stores is necessary to reduce the symptoms in workers, and increasing ventilation rates or using low-VOC-emission building materials may be practical solutions.

Summary: This study investigated the prevalence of sick building syndrome symptoms and its associated factors among residents in Nanjing, China. Females, residents with respiratory disease history, and from lower income families reported more sick building syndrome symptoms. Opening windows for more than 6 hours was found to be a protective factor for mucosal and dermal symptoms. Improving indoor environmental quality and adopting good lifestyle habits are important for preventing sick building syndrome symptoms.

Summary: In this study, indoor dust samples were collected from 40 houses in Shiraz, Iran and analyzed for Polycyclic Aromatic Hydrocarbons (PAHs). The study found that vehicular and cooking emissions were the main sources of PAHs in indoor dust. There was a significant association between total PAHs concentrations and symptoms of sick building syndrome. The study also revealed potential cancer risk from exposure to PAHs in household dust.

Summary: Indoor CO2 concentration is significantly associated with occupants' perceived stuffy odor and skin SBS symptoms; higher relative humidity is related to perceived moldy odor and humid air, while lower RH is connected to perceived dry air; high humidity can reduce mucosal and skin SBS symptoms, but its benefit for perceived dry air and skin dryness symptoms is weaker if there is a high CO2 concentration level.

Summary: Derived from the concept of inherent safety, inherent health is a new approach aimed at uncovering proactive solutions to reduce health risks at the source. This study investigated the feasibility of addressing Sick Building Syndrome through Inherent Health Oriented Design and developed contributory indices to quantify sickness severity. Results showed that sickness levels decreased by approximately 82% after implementing IHOD modifications, suggesting that the modified architectural design may be inherently healthier.

Summary: This study investigates the relationship between urban form and canopy layer urban heat island (CUHI) using a relatively large sample of microclimate sensors in Seoul, Korea. The study compares different statistical models and finds that the spatially explicit gradient boosting decision tree (GBDT) model has the highest accuracy. The study also shows that the effect of urban form on CUHI varies at different time instances during the day. These findings provide valuable insights for planners to understand the complexity of urban climate and reduce CUHI magnitude.

Summary: Windcatchers provide effective low-energy ventilation and summer passive cooling in temperate climates. However, their use in winter is limited due to significant ventilation heat loss and potential discomfort. This study evaluates the applicability of windcatchers in low-temperature conditions, highlighting the need for control strategies to reduce over-ventilation and the integration of heat recovery or thermal storage to enhance winter thermal conditions.

Summary: This study experimentally investigated the emission characteristics of droplets around the mouth during dental treatments. The results showed that the peak mass fraction of droplets occurs within the size range of 20 μm to 100 μm, and droplets with a diameter less than 200 μm account for over 80% of the mass fraction. The dominant emission direction of droplets is towards the dummy's head and chest, forming an approximately cone shape.

Summary: This study compared the effects of different respiratory behaviors on the distribution of aerosols in a ward and the risk of infection for healthcare workers using numerical simulation. It was found that talking in the ward significantly increased aerosol concentrations, particularly short periods of talking. Wards designed with side-supply ventilation had lower overall infection risk. Talking alternately between healthcare workers and patients slightly extended the impact time of aerosols.

Summary: Mixed-mode ventilation is a promising solution for achieving energy-efficient and comfortable indoor environments. This study found that occupants can thermally adapt when switching between natural ventilation (NV) and air-conditioning (AC) modes within the same day, with the adaptation process stabilizing between 35 to 45 minutes after the mode switch. These findings are important for optimizing thermal comfort in mixed-mode controls, considering the dynamic nature of thermal adaptation.

Summary: This study develops a method based on the LCZ framework for a comprehensive evaluation of urban-scale heat island effects, considering the impact of geographic factors on LST. The results show that Guilin's geomorphological conditions lead to abnormal heat island effects during winter, and the cooling effects of mountains and water bodies vary seasonally in different built areas, with LCZ 2 exhibiting the strongest cooling effect.

Summary: Monitoring the potential formaldehyde emission of wood-based materials through test chamber investigations has significantly contributed to reducing indoor formaldehyde concentrations. However, the different methodologies used in these procedures prevent direct result comparison. Empirical models for converting formaldehyde steady-state concentrations based on temperature, humidity, air change rate, and loading were developed in the 1970s and have been modified to accommodate the development of lower-emitting materials. Formaldehyde emissions from wood-based materials are complex and require nonlinear regression tools for mathematical analysis.

Summary: This study investigated the impact of reduced short-wavelength light on the hormone melatonin metabolite 6-sulfatoxymelatonin (u-sMEL) and examined the association between previous day's light exposure and u-sMEL. It was found that reducing short-wavelength light during the day did not change the concentration of u-sMEL. Personal photopic illuminance was positively correlated with u-sMEL in the reference week. The illuminance had a significant impact on u-sMEL, as shown by the evaluation of the mean of all three urine samples. However, this correlation was not found in the experimental week.
