This research paper examines Indoor Air Quality (IAQ) conditions in newly constructed apartments in Dubai to be more sustainable for residents to have healthier lifestyles. Enhanced airtightness and chemical-laden materials contribute to IAQ pollution in these buildings. The study aims to assess pollutant concentrations and variations based on building height. Measurements were conducted in 12 apartment units using the WHO’s IAQ assessment methodology. Most pollutants were within limits, but TVOC exceeded the Dubai Municipality’s standard, measuring at 2634.4 μg/m³, approximately nine times higher than the standard. HCHO (163.4 μg/m³) and toluene (551.4 μg/m³) were identified as significant pollutants with potential health effects. Analysis of pollutant concentrations based on building height revealed higher TVOC levels in upper areas, with 2,828 μg/m³ in the upper area compared to 2,443 μg/m³ in the lower area, indicating more severe indoor air pollution in Ethylbenzene and styrene also highest in upper areas, with ethylbenzene at 122 μg/m³ and styrene at 82 μg/m³ in the upper area, potentially due to elevated sources. Toluene and xylene concentrations were elevated in the middle area, with toluene at 574 μg/m³ and xylene at 321 μg/m³, likely influenced by materials and occupant activities. Benzene concentrations were consistent across all heights at 2.94 μg/m³, suggesting a common source. HCHO concentrations were relatively consistent but slightly higher in the middle and upper areas, with 171 μg/m³ in both, likely influenced by ventilation and emissions. While average pollutant concentrations met WHO standards, many units exceeded recommended limits, requiring targeted interventions. The study highlights the importance of addressing IAQ concerns and implementing strategies to reduce indoor air pollutants and improve ventilation. These findings contribute to IAQ knowledge in Dubai’s residential buildings, guiding policymakers, architects, and developers in effective policies and guidelines. Further research on seasonal variations and other IAQ factors is recommended for better understanding and long-term monitoring. Prioritizing IAQ in newly constructed apartments is crucial for healthier living in Dubai. The residential building sector can protect residents’ health by implementing appropriate measures while delivering upscale living experiences.

“…The interior of a building undergoes a continuous exchange of air with the external environment through ventilation and infiltration (Abdelaziz Mahmoud and Jung, 2023). During this process, PM infiltrates the indoor spaces through crevices or openings in the building's structure and windows (Jung et al, 2022a). The extent of its impact within a room depends on the specific pathways these particulates penetrate (Al .…”

In response to the growing concern of air pollution in Dubai, this study was undertaken to measure and analyze indoor and outdoor particulate matter (PM) concentrations in residential buildings during the spring dust storm period. The research focused on the infiltration of PM into indoor spaces and its impact on indoor air quality, exploring the relationship between PM particle diameter, building infiltration rates, and the indoor influence of outdoor PM. Conducted in a two-bedroom residential unit near a busy road, the study utilized particle size analysis and the indoor-outdoor (I/O) ratio for measurements. The findings revealed that smaller particles, particularly ultrafine PM2.5, had a more substantial influence on indoor PM concentrations than larger particles. It was noted that buildings with higher infiltration rates, especially those with natural ventilation, were more susceptible to outdoor PM infiltration. Additionally, the study highlighted the significant role of occupant behavior, such as cooking and cleaning, in generating indoor PM. However, further research is necessary to better understand the correlation between architectural characteristics, infiltration rates, and the indoor influence of outdoor PM in residential buildings. The study underscores the importance of improved ventilation systems, raising awareness of indoor air quality, and implementing effective mitigation strategies to reduce indoor air pollution and enhance indoor air quality in urban environments like Dubai. These findings contribute significantly to our understanding of indoor and outdoor PM dynamics, emphasizing the urgent need to address indoor air pollution in urban areas.

Indoor air quality in educational institutions: a comparative study of VOCs and bacterial contaminants in Dubai schools

Indoor Air Quality (IAQ) research in educational institutions is crucial for ensuring the health and wellbeing of students and staff. It also contributes to academic performance, energy efficiency, regulation compliance, and cost savings. This study conducted IAQ assessments in three school buildings in Dubai to address the lack of empirical data on IAQ in educational settings. It compared IAQ standards set by the Dubai Municipality with those established by the WHO. Measurements were taken in classrooms, computer labs, and science labs, revealing that some pollutants exceeded maintenance standards, including TVOC, airborne bacteria, and noise levels. However, formaldehyde and VOCs remained within acceptable limits. Computer labs exhibited higher TVOC levels than classrooms, while science labs had even higher levels. Science labs also had higher concentrations of formaldehyde. VOC concentrations generally met WHO standards, except for elevated levels of Benzene in the science lab. TVOC, formaldehyde, airborne bacteria, CO, CO2, and other substances showed higher levels during class sessions, whereas Benzene, Toluene, Ethylbenzene, Xylene, and NO2 exhibited higher levels when classes were not in session. The study also analyzed IAQ changes over time based on building construction age. Generally, TVOC, formaldehyde (HCHO), and other substances decreased over time. However, even in buildings older than 5 years, TVOC occasionally exceeded WHO standards. These findings emphasize the significance of monitoring and maintaining proper IAQ in educational institutions to create a healthy learning environment. Policymakers, school administrators, and researchers can use these insights to develop effective strategies for enhancing IAQ and safeguarding students’ and staff’s wellbeing and academic success.
