Summary: Wall constructions can passively regulate indoor Relative Humidity through moisture buffering. The hygroscopic materials' response to humidity and temperature variations impacts water vapor adsorption and desorption, with temperature affecting the rate and time lag of response. Developing laboratory tests that accurately represent materials' behavior in buildings, exposed to sine wave-forms, is crucial.

Summary: This study investigates the moisture buffering properties of paper plaster, specifically focusing on how different types of paper affect the properties of the plaster. The results show that paper plaster has excellent moisture absorption and buffering capabilities, making it a suitable material for environments with fluctuating humidity levels. Additionally, the study finds that the moisture buffering properties of paper plaster do not significantly differ based on the type of paper used, indicating that sorting paper before making paper plaster is unnecessary.

Summary: Geopolymers are materials that show promise for use in Net-Zero Buildings due to their low embodied energy and ability to passively control indoor microclimate. The influences of manufacturing parameters, such as initial water content and alkalinity, on the thermal, hydric, phase composition, and microstructure of aerated geopolymers were investigated. The results showed that these factors affect the properties of the geopolymers, but all the samples demonstrated potential for efficient modulation of indoor environment.

Summary: This paper presents two orthogonal experiments to examine the feasibility of using excavated soil and fine recycled concrete aggregate (FRCA) to manufacture unfired clay bricks (UCBs). The test results show that UCBs based on excavated soil and FRCA exhibit favorable water absorption, bulk density, compressive strength, and flexural strength. The optimal mix proportion is found to be w/c=0.65, a/s=0.5, c/s=0.3, and AC=5%.

Summary: The polychrome clay sculptures of the Buddha at Baosheng Temple in Suzhou, China are important cultural heritage with a long history. However, they are currently facing issues of cracking, peeling, and fading due to environmental factors. By analyzing the hygrothermal environment and temperature/moisture content near the sculptures, it is concluded that the conservation conditions need to be improved to reduce surface evaporation of the sculptures.

Summary: In this study, the ageing mechanisms and moisture absorption behavior of epoxy resins and carbon fiber composites were investigated. The results showed that the ageing process primarily involved physical adsorption of water, which did not significantly affect the chemical structure and microstructure. The absorbed water caused micro-cracks at the fiber-resin interface, weakening the interfacial strength and reducing the mechanical properties of the composites.

Summary: The investigation focuses on the reflection issue in a hygrothermal medium in nonlocal elasticity. By formulating and solving the governing equations of a hygro-thermoelastic material, the velocity equation is obtained. The solution predicts the propagation of longitudinal displacement, P-wave, thermal diffusion TD-wave, moisture diffusion mD-wave, and shear vertical SV wave in the medium. The velocities of different waves are calculated, and the effects of hygrothermal parameters and nonlocal parameter on velocity, reflection coefficient, and energy ratio are shown graphically.

Summary: This study evaluates the effect of natural polysaccharide solutions (starch, alginate, and chitosan) on clay composite properties. The authors describe the process of obtaining gelated biopolymers and analyze characteristics such as viscosity and pH. Results show that increasing the concentration of biopolymer decreases the bulk density and shrinkage of clay composite materials. Additionally, the application of starch and alginate solutions enhances compressive strength and moisture adsorption degree, while also affecting the structure and water erosion behavior of the clay composite.

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.

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.
