Therefore, there is a need to develop an eco-friendly aerosol suppressant to control the radioactive aerosol. In this paper, carboxymethyl cellulose (CMC), polyvinyl alcohol (PVA), rhamnolipid and sophorajaponica glycolipid were selected as the raw material, and the aerosol suppressant was prepared by solution polymerization. The sample was characterized by FTIR, TGA, viscosity, surface tension and contact angle analysis. The results indicated that the grafted reaction was successful. Rhamnolipid and sophorajaponica glycolipid effectively reduced the surface tension of the copolymer solution to 27.7 mN/m, and the contact angle between the polymer solution and experimental dust was decreased to 27.36°. The aerosol sedimentation experiment showed that the suppressant had a significant effect on aerosol. The sedimentation efficiency of concrete aerosols was 87.7%, and the sedimentation efficiency of radioactive aerosols reached 90.8%. It provided an eco-friendly and effective method to quickly and easily control and remove high-concentration radioactive aerosol.","PeriodicalId":13578,"journal":{"name":"Indoor and Built Environment","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142251715","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}

This study examined a site museum, analyzing the traditional suspended ceiling air-conditioning system and proposing a more rational renovation. Using computational fluid dynamics (CFD) numerical simulations, the study evaluated the effects of both systems on site protection and thermal comfort. The results indicated that the retrofit scheme could significantly reduce the indoor air velocity and temperature with the same air supply parameters, which would improve human thermal comfort and also reduce the negative impact of temperature and wind speed on the site. Additionally, the retrofit scheme cut air-conditioning energy consumption by 40% and reduced initial investment costs for a unit with a rated airflow of 62,000 m³/h. The optimization of the air-conditioning system ends was also carefully considered, resulting in a safer and easier installation and maintenance process, as well as enhancing the visual appeal of the museum’s interior. The proposed retrofit scheme can provide a reference for the design of air-conditioning systems in similar types of buildings.","PeriodicalId":13578,"journal":{"name":"Indoor and Built Environment","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142251713","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}

This study explored the Computational Fluid Dynamics (CFD) method for accurately predicting the inactivation efficiency of ID-UVs. The results showed that the setting of ‘Divisions’ is crucial to the accuracy of radiation field modelling, and 15 × 15 was considered to be a reasonable value in this study. In addition, residence time and deposition ratio are two crucial parameters determining the average UV dose (AD) received by microbial particles, thereby influencing the inactivation efficiency. For ID-UVs without ribs, the Renormalization Group (RNG) [Formula: see text] model largely overestimated these two parameters, while the Reynolds Stress Model (RSM) with correcting fluctuation velocity improved the predictive accuracy of AD by 10.0%. For ID-UVs with ribs, the RNG [Formula: see text] model overestimated the eddy size and AD by 28.6% and 12.0%, respectively. The RSM model provided results closer to the Large Eddy Simulation. Adding 0.10 H (H: duct height) ribs increased the inactivation efficiency for MS2 Bacteriophage by 19.0%–64.3%, with an additional pressure drop of only 3.3 Pa.

Statistical analysis revealed significant disparities in ventilation frequency and satisfaction with indoor temperature. The survey results indicate that the primary mode of indoor air exchange amongst Changchun residents is window ventilation, accounting for 93%. Field tracking was conducted to measure indoor air concentrations of volatile organic compounds (VOCs) in residential buildings during winter and summer seasons. The study revealed a significant increase in the average indoor/outdoor (I/O) ratio of the targeted 25 VOC concentrations in winter, rising from 10.8 to 17.7. The findings underscore indoor sources as predominant contributors to the measured VOCs. Temperature, humidity and room functions are the main factors affecting VOC concentration. Higher temperatures and increased relative humidity both contributed to elevated indoor VOC levels. This study recommended the opening of more windows during high temperature and high humidity in summer, to maintain good indoor air quality and effectively age the emission of VOCs from furniture. This study contributes to the enhancement of the database on indoor air quality and effective ventilation strategies in cold regions for safeguarding public health.","PeriodicalId":13578,"journal":{"name":"Indoor and Built Environment","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142251712","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, a method for leakage source identification in industrial factories combining with computational fluid dynamics (CFD) and correlation coefficient was proposed and validated. The study first experimentally validated the numerical methods, which were fundamental to the leakage identification method. Then impacts of leakage sources, sensor errors and number of sensors on the source identification results were evaluated. The results showed that the identification accuracy could be significantly improved by refining the step size of the coefficient a r in this method. When the number of leakage sources was unknown, the accuracy of this method in identifying the number and location of leakages was 93.5%. The computation time spent on source identification depended on the maximum number of leakage sources. Using four sensors with errors were enough to identify the number of unknown leakage sources. The number of leakage sources did not exceed three at the same time. Overall, coupled CFD and correlation coefficients method could effectively identify the number, location and intensity of leakages.","PeriodicalId":13578,"journal":{"name":"Indoor and Built Environment","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142251714","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 aim is to describe and analyse measured and perceived IAQ, and residents’ health symptoms. We found a lower relative humidity, temperature (TP) and air change level (h−1) level, and a higher carbon dioxide (CO2) level during winter compared to summer. In general, higher IAQ levels were measured in apartments with increased crowdedness. The inability to be able to create cross ventilation increased TP, and a larger number of rooms decreased TP. Overall, there was no clear alignment between measured and perceived IAQ, but we found a trend that higher CO2-levels led to a perception of poor IAQ especially during summer. Overall, draught and thermal discomfort were the most common complaints. Self-reported humidity was increased during winter and was associated with nasal and respiratory symptoms, whereas self-reported humidity during summer was associated with fatigue and dermal symptoms.

In this research, air velocity and NO2 concentration were considered as the air quality parameters. Steady 3-dimensional flow was used to simulate these cases using the SST k-[Formula: see text] turbulence model, which was numerically solved based on the Reynolds-averaged Navier–Stokes (RANS) equations. The CFD software used in this research was validated in comparison with wind tunnel tests and acceptable results were found. The TOPSIS multi-criteria decision-making method was used to choose the best case based on increasing the air velocity and decreasing amount of pollutant inside the building. The results show that the best and worst building forms are related to the step-shaped and the L-shaped form, respectively.

Nevertheless, achieving the sustainable and high-quality organic renewal of urban residential property plots poses a significant challenge for planning. This study postulates that the crux of organic renewal for urban residential property plots lies in the impacts on improvement for sustainable built environment, with the main obstacle being the organization and implementation of intricate renewal activities. A potential solution is to enhance land property value, while establishing a digital twin to optimize the design of renewal strategies and implement renewal activities precisely and efficiently. This study scrutinizes the characteristics of the property value composition of urban residential property plots, investigates basic strategies of organic urban renewal and proposes a theoretical framework to elucidate dynamic property value change, property value enhancement and incremental value allocation during the renewal process. Additionally, a theoretical concept was developed to efficiently promote property value in organic renewal through digital twin construction. A comprehensive case study showcases the pronounced benefits of property plot renewal, including a 1.17-fold increase in floor area and a 50% rise in residential floor area unit prices. The research framework proposed in this study is conducive to promoting the optimization, fair allocation and efficient implementation of property value in organic renewal. Furthermore, it is conducive to practicing ‘human-centric’ decision-making.","PeriodicalId":13578,"journal":{"name":"Indoor and Built Environment","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142216275","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}

While these external interventions protect the cultural heritage of traditional villages and provide opportunities for development, they have gradually eroded their intrinsic adaptive cycle system. This study focused on 6819 traditional villages, revealed the characteristics and transitions of the adaptive cycle stages in traditional villages and described the internal mechanisms of adaptability within these villages. The research findings are as follows: Regarding adaptability characterisation, the adaptability of traditional villages has developed a regionally significant imbalance. The highest proportion of adaptability cycle stages was found in the poverty trap, exploration (r) and gambling traps. Traditional villages are mostly in a rigid state, with a few adaptive processes shifting between the poverty trap and exploration (r), requiring a new impetus to guide positive cycles. In terms of adaptability mechanisms, there was a significant negative relationship between locality, mobility and resilience in traditional villages. Intrinsic adaptive mechanisms gradually disintegrate, and there is an increasing risk of falling into a lock-in trap. This study provides empirical evidence for analysing the issues in traditional villages and offers recommendations for long-term planning and policy formulation of locality protection in traditional villages.","PeriodicalId":13578,"journal":{"name":"Indoor and Built Environment","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142216277","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}

This work presents the homologous clustering optimization algorithm (HCO) as a solution to the limitations of existing optimization approaches. It also compares HCO with the multi-objective evolutionary mating algorithm (MOMA). HCO with a coefficient of eight performed better than MOMA. The Pareto frontier generated by HCO was more succinct, and the computational time was reduced by 52%. Moreover, an analysis of the CFD simulation results revealed that, in the context of this study, the influence of the interface width coefficient was greater than that of the interface height, and the impact of the cavity width was greater than that of the cavity height.
