The indoor environment in most of the tropical coastal regions is associated with the residents’ health and well-being. However, limited studies reported on quantifying the interrelation between indoor environmental quality, thermal comfort and residents’ health risks in such climatic regions. Here, we evaluate indoor thermal comfort in coastal eastern India that falls under the ‘ Tropical Savanna’ climatic region. The perception survey was conducted to collect primary data in summer, monsoon, post-monsoon and winter across the year and the perception of warmth appeared to have a similar trend to direct and rational human thermal indices derived from a composite body heat exchange. Results indicate that indoor thermal stress significantly differed ( p < .05) between seasons and across study locations. The maximum summer and monsoon days lay in a warm to very hot zone. Additionally, most of the heat-related stress or disorders significantly differed ( p < .01) amongst different age groups of people. Finally, a principal component analysis using the human thermal indices yielded three groups of heat-related symptoms (a) physical fatigue and responses, (b) neural stressors and (c) hyperhidrosis disorder. Overall, results suggested that physical fatigue and responses arose predominantly from climate-induced thermal stress. The study recommends an effective bioclimatic design strategy following human-environment friendliness that can improve indoor thermal comfort in coastal eastern India.

The phenomenon of ‘pollution for promotion’ has been addressed in the literature from the perspective of tax competition or local protection, but the underlying institutional causes have not been thoroughly discussed. In this study, we put forward the theoretical hypothesis of ‘industrial pollution as a last resort due to reliance on commodity taxes’ and empirically tested this hypothesis using data on commodity taxes and industrial pollution in prefecture-level cities from 2003 to 2019. Our findings indicate that a 1% increase in the share of GST (Goods and Services Tax) is associated with a significant average increase of approximately 0.51% in industrial pollution. The primary channels through which GST affects industrial pollution include the expansion of production scale amongst heavy polluters, reduced environmental requirements for large taxpayers and increased land development. Commodity tax dependence creates a barrier for local governments to adopt more sustainable economic development models, leading to increased industrial pollution. The findings of this study contribute to a better understanding of the institutional barriers during China’s economic transformation, shed light on the responses of firms and governments within existing institutional frameworks, and provide policy insights for transitioning towards high-quality economic development.

National health could significantly impact political, economic and social spheres, having a critical role in national development, social stability and sustainable economic growth. The Chinese government is prioritizing health in all policies and promoting environmental health work. However, deviations in the implementation of China’s environmental health policy, such as excessive or incomplete execution, could hinder progress. Studies have identified the main factors that are inhibiting effective policy implementation; these include incomplete grassroots policy mechanisms, cognitive biases amongst policy executors, varying acceptance of policy execution objects and environmental complexity. To mitigate these issues, several actions have been recommended including improving government mechanisms, enhancing technical support, developing talents, increasing public scientific literacy and considering the needs of policy executors and environmental complexity. The Internet, especially self-media platforms, can enhance policy communication, reduce information bias and foster a favourable environment for policy implementation. By using self-media’s dissemination mechanism effectively, we can strengthen public consensus and improve public scientific literacy in environmental health. This contributes to eliminating policy formulation and implementation deviations, fully leveraging the guiding role of policies and promoting the construction of a Healthy China.

Water damage affects both residents and buildings. Issues include moisture, climate impact and repair costs that amount to immense resources. Because of these, immense resources research is important to undertake to reduce and limit the extent and effects of water damage. This study aimed to compile and review the literature on water damage in buildings. Literature distribution, the status, consequences, effects, and strategies and methods for prevention of water damage were assessed by compiling and reviewing literature using quantitative and qualitative methods. Two scientific databases were searched to identify the relevant literature. Key findings of this study are that research conducted on water damage is embedded in the study of building defects and building pathology, and more specific research on water damage is needed depending on different rooms and buildings, the effect of moisture and sustainability. Informed and guided decisions, management and organizational structures have been internationally suggested as a part of the solution to reducing the amount and effect of defects and could have the possibility to reduce the amount and effect of water damage. However, there is a gap in research on water damage consequences, occurrence and costs in Nordic conditions.

This study analysed the performance of a hot-water pipe (HWP) and fan-coil units (FCUs) in controlling microclimate conditions in a net-zero energy greenhouse (NZEG). The performance of a previously developed TraNsient SYstem Simulation (TRNSYS) model for the NZEG was enhanced to include a crop model and several HWP emission standards, and the improved TRNSYS model was used to analyse heating, ventilation and air-conditioning (HVAC) systems for different greenhouse sizes in the Republic of Korea. Further, an economic analysis was conducted. The model validation showed excellent agreement between the measured and simulated values, with Nash-Sutcliffe efficiency of 0.98. The presence of crop in the simulation model reduced the total heating load by 14.5 MWh and increased the cooling load by 4 MWh. The capacity of the FCU was increased as the outside temperature rose from 33.4[Formula: see text] to 36.4[Formula: see text] in summer, and the diameter of the HWP was decreased from 25A to 10A as the outside temperature rose from −21.7[Formula: see text] to −12.2[Formula: see text] in winter to maintain the greenhouse at the desired temperature of 15[Formula: see text]. Notably, the payback period was reduced by 9 years when the annual savings in heating energy costs and revenue from carbon trading were considered as a part of the net economic cash flow.

Microplastics (MPs), measuring less than 5 mm, have been causing environmental concerns in aquatic ecosystems, and less work has been done in indoor environments, where humans spend most of their lives. This finding revealed a diverse range of MPs within indoor house dust samples. These MPs encompassed fibres, fragments, foams, pellets and films. Due to the ubiquity of textile-based items, fibres are the most common indoor MP. The MPs have different colours like black, red, blue, yellow, white and brown. The study revealed there were substantial differences in MP sizes across different households. The average size range was 178.87–3713.99 µm. One hundred eighteen particles were identified as MPs. The study identified 22 types of MPs, shedding light on these materials’ extensive sources and applications in everyday household items. MPs in indoor environments raise concerns about potential human exposure and underscore the need for further research into their health implications. The MPs found in most indoor house samples were low-density polyethylene, polyethylene, polypropylene, polyamide, polyvinyl chloride, high-density polyethylene and polystyrene. Carbon, nitrogen, fluorine, sodium, sulphur, potassium, calcium, zinc, oxygen and magnesium were the common elements in all indoor house dust samples. Compared with the active sampling, slightly more work has been done on the indoor house dust samples.

Pollutants such as formaldehyde, benzene series compounds and total volatile organic compounds (TVOC) released by residential interior decoration activities (including household renovation and new furniture) pose a severe threat to children’s respiratory health. To study the effect of indoor decoration on children’s respiratory diseases and provide suggestions to prevent it, we conducted a cross-sectional questionnaire survey amongst 6547 preschoolers from 34 kindergartens in Chongqing, China, and selected 39 houses to measure their indoor air pollutants concentrations. The results showed that household decoration, during pregnancy and early childhood, would increase the risk of children’s rhinitis, asthma and pneumonia. Vacancy time after the completion of decoration, furniture pieces and decoration materials significantly affected the concentration of formaldehyde, xylene and TVOC, which could pose a potential risk to children’s respiratory health. The concentration of xylene and TVOC and the incidence of children’s asthma and pneumonia were both negatively correlated with the vacancy time. Decoration materials such as composite and ceramic tile/stone/cement flooring and water-based/latex/oil-based paints emit more gaseous pollutants than solid wood flooring and wallpaper, respectively, which were more likely to increase the risk of children’s respiratory diseases. Adequate ventilation and air purification can reduce the impact of home decoration.

Interior contour, an essential component of the built environment, has drawn wide attention from home and abroad. From the perspective of neuroaesthetics, preference for architectural interior contour is closely tied to brain activity. Therefore, revealing the underlying neural basis of aesthetic preferences for architectural interior contour in terms of neuroimaging is of great importance. We recruited 30 healthy participants for behavioural assessment and functional magnetic resonance imaging (fMRI) scans. Using percent amplitude of fluctuation (PerAF), the current study measured participants’ neuroaesthetic responses to curvilinear and rectilinear architectural interior contours in the three frequency bands. When participants viewed architectural images with curvilinear contours, the PerAF was significantly reduced in multiple brain regions, in comparison to rectilinear architectural interior contours. Moreover, significant negative correlations were observed between ratings of aesthetic judgments of curvilinear space and increased PerAF values in specific regions including the left Rolandic operculum. Aesthetic judgments were significantly correlated with PerAF values in specific brain regions, including the left middle frontal gyrus. Our study reveals that participants have a higher preference for curvilinear contours over rectilinear contours. Neural response varied across different architectural contours, highlighting the complex interplay of neural mechanisms underlying aesthetic perception.

An empirical correlation and a set of machine learning (ML) models were developed to estimate droplet size and count distributions over an extended duration after a cough at different relative humidities (RHs), air temperatures and locations within an indoor environment. Experiments covered RHs of 20%–80% and air temperatures of 21 °C–26 °C. Droplet count distributions for 4 size bins (0.3–0.5, 0.5–1, 1–3 and 3–5 μm) were recorded for 70 min within the distance of 2 m from the cough source. Different ML models, including decision tree, random forest and artificial neural network, were trained for each size bin to predict the associated count distribution. Amongst these models, random forest showed a slight superiority in performance. The coefficient of determination for the random forest models ranged from 0.912 to 0.989, indicating robust correlations between the features and the response variables. An empirical correlation was established linking the count distribution of 0.3–0.5 μm droplets to time, RH and distance along the cough direction. Both ML models and the correlation accurately predicted the trends and the distributions, providing valuable data for validating computational simulations and informing indoor environment control systems to reduce the risk of virus transmission.

Both ML models and the correlation accurately predicted the trends and the distributions, providing valuable data for validating computational simulations and informing indoor environment control systems to reduce the risk of virus transmission.","PeriodicalId":13578,"journal":{"name":"Indoor and Built Environment","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140582211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
