However, its electricity consumption and carbon emissions are considerable due to the continuous operation of environmental control, the energy consumption of air cooling in exhibition halls can reach more than 10 times that of office buildings. To further reduce energy consumption, this current study drew on the concept of NBS (Nature Based Solution) and proposed a low-carbon environmental control system for an enclosed exhibition hall for storage of earthen relics by applying natural energy (solar photovoltaic and earth-air-cooling) and space optimization. Firstly, a numerical model was established to simulate the preservation environment in exhibition halls and the electricity consumption of each energy subsystem. Then the model was applied to optimize the design parameters (e.g. earth-air tunnel and airflow pattern) for the environmental control system. Numerical results showed that the electricity consumption was reduced by 58% by applying earth-air-cooling and solar photovoltaic. After optimization of the exhibition hall height, electricity consumption was approximately reduced by 65%. This research is of great value to mitigate energy consumption problems encountered in earthen relics museums and other similar environments.","PeriodicalId":13578,"journal":{"name":"Indoor and Built Environment","volume":"35 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140034283","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}

In this study, indoor and outdoor air samples were collected and analysed to investigate the indoor and outdoor pollution of PM<jats:sub>2.5</jats:sub> and its metal elements during the Chinese New Year. The findings reveal that there is a notable positive correlation between indoor and outdoor PM<jats:sub>2.5</jats:sub> concentrations during the Chinese New Year, with outdoor concentrations being higher on average. The levels of PM<jats:sub>2.5</jats:sub> concentrations indoors and outdoors started to increase on Chinese New Year’s Eve and peaked after the early hours of the Chinese New Year. The total concentrations of six metal elements (Cd, Cr, Ni, Cu, Pb and Zn) in indoor and outdoor PM<jats:sub>2.5</jats:sub> during the Chinese New Year in 2022 were 738.73 ± 134.93 mg/kg and 1124.38 ± 553.14 mg/kg, respectively. Principal component analysis suggests that the main sources of indoor metal elements were from outdoor combustion sources and human activities, while outdoor sources were fireworks displays and emissions from coal combustion. Based on the U.S. EPA risk assessment carried out, both indoor and outdoor PM<jats:sub>2.5</jats:sub> metal elements could pose a carcinogenic risk to adults.","PeriodicalId":13578,"journal":{"name":"Indoor and Built Environment","volume":"79 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140002112","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}

Most studies related to droplet evaporation only focus on the evaporation process, without dividing the transmission routes of diseases caused by droplet evaporation. In this paper, the actual size of droplet nuclei was analyzed, and droplet evaporation and the changes in component content were predicted. Especially considering the dynamic effect of evaporation on droplets size change, a more realistic sedimentation model was established, and the probability of pathogen transmission through different routes and the corresponding droplet size distribution range were analyzed. The results showed that the size of droplet nuclei and the rate of the evaporation process together determined the time required for droplet evaporation. The number of droplets still suspended in the air after the end of evaporation is much higher than the number of droplets settling on the ground. In addition, the differences in component content during the evaporation process may affect the inactivation of pathogens in droplets. This study provided a reference for the prevention and control strategies of respiratory infectious diseases in indoor environments.","PeriodicalId":13578,"journal":{"name":"Indoor and Built Environment","volume":"242 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139955550","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}

To address this challenge, a systematic and effective decision-making method is required to select optimal building retrofit measures in alignment with Algeria’s 2030 energy strategy. In this study, we propose an innovative approach based on the Fuzzy Analytical Hierarchy Process (FAHP), a widely used multi-criteria decision-making method, to evaluate and prioritize different retrofit measures. The FAHP allows decision-makers to have a comprehensive framework for making informed choices by incorporating independently proposed economic, environmental and technical criteria. The results demonstrate the high significance of retrofit measures that enhance thermal insulation, with double glazing and roof insulation emerging as top priorities. Sensitivity analyses confirm the stability and robustness of the decision-making process. This approach offers valuable insights for policymakers and building professionals seeking to implement sustainable and energy-efficient retrofitting strategies in Algeria’s construction sector. By aligning with the country’s energy goals, this decision-making method contributes to achieving a more sustainable and environmentally responsible built environment.","PeriodicalId":13578,"journal":{"name":"Indoor and Built Environment","volume":"153 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139955468","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}

The effect of different forms of cold surfaces on human thermal comfort is focused on its application. A novel natural convection-radiant evaporator for heat pumps was developed and its influence on thermal comfort was investigated. A numerical model of the chamber with the evaporator was established and verified with experimental results. Thermal comfort experiments were conducted in a climate chamber and the influence of its asymmetric and uneven cold radiation on the thermal comfort was investigated. Due to the limitation of PMV in uneven radiation situations, the revised predicted mean vote (RPMV) was proposed to assess the thermal comfort in asymmetric and uneven radiation environments based on experimental results. Based on RPMV, the influence of the surface area and temperature of the evaporator on thermal comfort was numerically analyzed. The results indicate that indoor air temperature and relative humidity, RPMV increase with the increase of plate temperature, but decrease with an increase in plate area. The most favourable indoor thermal comfort environment was obtained at an indoor air temperature of 28°C and relative humidity of 50%, which is 2°C higher than traditional air conditioning system.","PeriodicalId":13578,"journal":{"name":"Indoor and Built Environment","volume":"22 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139955463","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}

The exchange and mutual learning amongst the Yellow River Basin, Yangtze River Basin and Grand Canal region promote the diversity and innovation of culture, making them the ‘typical containers’ of Chinese civilisation. Based on the uniqueness and correlation of regions such as the Yellow River Basin, Yangtze River Basin and Grand Canal, this study constructs the concept of a ‘Yellow-Canal-Yangtze’ watershed community, combining existing disciplinary advances and summarizing its spatial, temporal and elemental characteristics. This research is conducive to promoting the creative transformation and innovative development of excellent traditional culture, assisting in the protection of watershed cultural heritage systems and the governance of watershed ecosystems, and promoting regional coordinated and interconnected development.","PeriodicalId":13578,"journal":{"name":"Indoor and Built Environment","volume":"102 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139955570","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}

Therefore, a series of wind tunnel tests were conducted on a real building complex to investigate the impacts of a newly built nearby high-rise building, added floors, passage width and a novelty zigzag building shape on the PLW. The findings showed that in converging layouts, PLW velocity can be increased up to 2.75 times by a nearby 230 m high-rise building, and it is reduced by 30% with a 30 m passage compared to a 10 m passage. Adding 38 m to a 65 m high building would increase PLW velocity by 1.95 times when compared to an isolated building and 2.4 times when compared to a building surrounded by others. Additionally, a modest impact on PLW velocity was observed with zigzag building shapes. This study highlights the PLW velocity that can be increased to a large extent with newly built high-rise buildings and adding floors, while increasing the passage width has the opposite effect.

Initially, the relationship between architecture and respiratory infections was examined using the descriptive-analytical method and library research, and the operational spaces impact on airborne transmissions was identified. Subsequently, a conceptual model for flexible design was developed. A questionnaire was then distributed amongst architecture experts, and the results were compared through the Friedman test and Shannon’s entropy to prioritize flexible design strategies for dormitories during quarantine. Amongst these strategies, ‘segregation of space’ had the highest impact on the operational spaces of dormitories. Generally, the priorities of employing flexible strategies on dormitory spaces are as follows: ‘privatizing wet spaces’, ‘converting communal rooms into suites’, ‘splitting suites’, ‘creating screening spaces’, and ‘designing hierarchical access’. Next, a case study was conducted on the current dormitory of the Iran University of Science and Technology, and a proposed dormitory was presented based on the prioritized strategies. Finally, the current and the suggested dormitory were compared with space syntax criteria, including connectivity, depth and integration, and the pandemic responsiveness of the new plan was evaluated.","PeriodicalId":13578,"journal":{"name":"Indoor and Built Environment","volume":"66 23","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139440982","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}
