Summary: In educational buildings, adaptive strategies can be implemented to achieve thermal comfort and reduce energy consumption. The role of climate in defining different adaptive capacities, thermal neutrality, comfort, and preference needs to be understood. A study was conducted on 17 naturally ventilated university classrooms from 10 buildings in Italy and France, collecting 1377 questionnaires related to environmental parameters. The results showed that despite performing fewer adaptive actions, French students had a lower neutral temperature compared to Italian students, indicating a climate-dependent adaptation.

Summary: This research focuses on the potential of courtyards as semi-outdoor spaces in improving thermal comfort in Mediterranean cities, and extends existing calculation models to determine comfort levels in courtyards during typical summer and heat wave periods in Cordoba, Spain. Results show that courtyards can provide cooler temperatures compared to outdoors, but comfort levels drop during heat wave periods despite increasing thermal gaps. The study also compares the results with the PET indicator for outdoor thermal comfort and evaluates the implications of implementing passive shading strategies in courtyards.

Summary: Preschool children have different thermal comfort perceptions compared to adults, and parents or grandparents may create an inappropriate thermal environment for their children. Preschool children have a higher tolerance to cool environments compared to adults, requiring lower neutral temperatures and wider acceptable temperature ranges. Touching the children's skin can help parents more accurately infer their thermal perceptions.

Summary: Component testing has shown that using walls built from upcycled sand-filled plastic bottles can reduce overheating in tropical buildings, while also reducing costs and preventing waste pollution. However, the influence of these bottle-composite walls on thermal comfort in actual dwellings is still unknown. This study presents the first in-situ measurement of indoor temperature in a bottle house compared to traditional dwellings, and the results show that the bottle house is cooler than the mud and sandcrete dwellings, although additional heat mitigation measures are still required for comfortable temperatures on the hottest days.

Summary: This study aimed to investigate the thermal comfort requirements in residential buildings and establish an adaptive thermal comfort model. A two-year field study was conducted on residential buildings in Shaoxing, Zhejiang Province, China. The results showed that the thermal comfort requirements of residents change with the seasons and seasonal models reflect the residents' thermal adaptation caused by dynamic climate change more comprehensively and accurately. In addition, this study determined the residents' psychological and behavioural adaptability to the seasons and found the characteristics of thermal sensation and requirements for thermal comfort in different seasons. The results could be used as a basis to improve energy efficiency and meet comfort needs in the future.

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.

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: 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.
