Several research studies have ranked indoor pollution among the top environmental risks to public health in recent years. Good air quality is an essential component of a healthy environment and significantly affects human well-being. Poor such environments may cause respiratory disease for millions pupils around globe and, current pandemic-dominated era, require ever more urgent actions tackle burden its impacts. The poor could result from management, operation, maintenance, cleaning. Pupils are different segment population adults many ways, they exposed environment: They breathe per unit weight sensitive heat/cold moisture. Thus, their vulnerability higher than adults, conditions affect proper development. However, learning can reduce absence rate, improves test scores, enhances pupil/teacher learning/teaching productivity. In this article, we analyzed literature on schools, with primary focus ventilation, thermal comfort, productivity, exposure risk. This study conducts comprehensive review summarizes existing knowledge highlight latest solutions proposes roadmap future school environment. conclusion, summarize critical limitations studies, reveal insights directions, propose further improvements quality. More parameters specific data should be obtained in-site measurements get in-depth understanding at contaminant characteristics. Meanwhile, site-specific strategies locations, as proximity transportation routes industrial areas, developed suit characteristics schools regions. socio-economic consequences performance effects children classrooms considered. There great need larger sample sizes exposure, student performance, satisfaction. complex mitigation measures evaluated by considering energy efficiency, IAQ effects.

Ventilation Strategies for Mitigation of Infection Disease Transmission in an Indoor Environment: A Case Study in Office

Buildings, Journal Year: 2022, Volume and Issue: 12(2), P. 180 - 180

Published: Feb. 4, 2022

During the normalization phase of COVID-19 epidemic, society has gradually reverted to using building space, especially for public buildings, e.g., offices. Prevention airborne pollutants emerged as a major challenge. Ventilation strategies can contribute mitigating spread disease in an indoor environment, including increasing supply air rate, modifying ventilation mode, etc. The larger rate inevitably lead high energy consumption, which may be also ineffective reducing infection risk. As critical factor affecting viral contaminant, potential modes control should explored. This study compared several office, mixing (MV), zone (ZV), stratum (SV) and displacement (DV), through analyzing performance risk optimal one. By ANSYS Fluent, distributions airflow pollutant were simulated under various infected occupants. SV showed greater than MV, ZV DV, with distribution index (ADPI) 90.5% minimum 13%. work provide reference development space oriented prevention COVID-19.

Evaluation of ventilation and indoor air quality inside bedrooms of an elderly care centre

Energy and Buildings, Journal Year: 2024, Volume and Issue: 313, P. 114245 - 114245

Published: May 8, 2024

Ventilation and indoor air quality are important factors that affect the health of elderly. The purpose this study was to find effective ventilation design measures for improving in typical two-bed bedrooms elderly care centres (ECCs). Mixing (MV), displacement (DV), zone (ZV) stratum (SV) were analysed with twelve scenarios most solutions including six curtains between beds without beds. Airflow distribution, CO2 concentration, efficiency risk assessment adopted discussion. SV found be an method ECC bedroom while also taking into account needs rights residents, such as privacy. Comparing under same types ventilation, showed a slight (≤8%) decrease concentration pillow area. However, could increase virus transmission compromise privacy, so it is not recommended. Regarding beds, contaminant removal (CRE) using increased by 2.58, 3.22 2.12 times compared MV, DV, ZV respectively. Additionally, ratio (HR) reduced 46.3 %, 53.7 41.7 %. Hence, recommended install apply bedrooms. This can used guide systematically designing systems Furthermore, collaboration among environmental engineers, designers, policymakers, wider community essential develop sustainable environments
