Summary: This study comprehensively evaluates the energy-saving potential and visual comfort aspects of electrochromic smart windows in hot-humid climate office buildings. The results show significant energy savings of 23% with EC windows using daylighting control but limited visual comfort in some areas. On the other hand, EC windows with glare control achieve 17% energy savings while maintaining visual comfort throughout the building. Further research is needed to optimize performance for different building types and climates.

Summary: Daylight is crucial for human well-being, but glare can be a problem in office buildings with large windows and glass facades. Traditional shading systems may not effectively adapt to changing sky conditions, while electrochromic (EC) glass offers better light transmission control. By using reinforcement learning with a DQN agent, glare scenarios can be avoided effectively, increasing the amount of useful daylight and reducing the need for artificial lighting.

Summary: Daylight control systems (DCSs) are formed by coupling glazing and shading systems to enhance visual comfort and energy efficiency in buildings. However, there is an inherent contradiction in the design of DCSs, as daylight can simultaneously affect energy efficiency and glare. A study evaluating 155 DCSs using multi-criteria decision-making (MCDM) method found that coupling reflected horizontal louvers with vacuum glazing is the most effective design alternative regardless of orientation, with south-facing buildings being the optimal choice for achieving daylighting, glare reduction, and energy efficiency simultaneously.

Summary: Shading devices can reduce glare and improve visual comfort in buildings by controlling excessive daylight. However, they may overly reduce illuminance levels. This study proposed a parameterization method for selecting a shading strategy that reduces glare while maintaining satisfactory daylighting levels. The method involves constructing Pareto sets based on a multi-objective genetic algorithm and combining dynamic glare and daylight evaluation indicators. A case study comparing four shading strategies was conducted, and the results showed that the shading strategies had different performances in terms of illuminance levels and glare reduction. The developed method can be a useful tool for designing appropriate daylighting environments.

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: 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: 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: 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.
