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: Most people today spend a lot of time in an artificial lighting environment, which can lead to problems with sleep, mental health, and circadian rhythm due to lack of exposure to natural daylight. Dynamic lighting, which can change throughout the day, is considered an effective solution. However, it is still unclear whether the simultaneousness of daylight in dynamic lighting is beneficial. A lab-based study found that dynamic lighting that simulates the simultaneous information of daylight had positive effects on psychological states, but did not have an impact on cognitive performance.

Summary: With the rapid improvement in artificial lighting systems, the challenges for energy-saving daylighting systems will become more difficult in the future. A field survey was conducted to explore the benefits of daylighting from the perspective of customers in shopping malls. The study found that daylighting is more important for improving users' mood than saving energy. Illumination was ranked as the most important element in the shopping malls' internal environment, and the connection to outside views and the presence of sunlight enhanced customers' ability to recognize daylight utilization and increased their satisfaction. Lighting quality, rather than the source of lighting, plays a significant role in enhancing customer satisfaction.

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.
