“…The measurements followed the World Health Organization's (WHO) recommended IAQ assessment methodology for newly built apartments (Singer et al, 2020;Hussien et al, 2023b). The procedure involved a ventilation period of 30 min, followed by keeping the target unit's room open for over 5 h (Bekö et al, 2020).…”

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.

“…Wind can be filtered or deflected by constructing bamboo, reed screens, trellises, walls, or tall parapets [26,79,81,92,95,98,100,101,105,107,110]. (4) Shade: rooftops near taller buildings are not ideal places for setting up rooftop farms due to neighboring buildings' cast shade [81,92,115]. (5) Water source: Proximity to a water source, such as an outdoor faucet on the rooftop, is essential [87,95,98,100,106,116].…”

“…(10) Limited rooftop space: Rooftops usually house vital mechanical systems and equipment, such as chiller plants, water tanks, solar water heaters, lift motor rooms, TV antennae, and pipes. Therefore, there might be insufficient room for cultivating food on rooftops [115]. (11) Building codes and legislation: The rooftop design should comply with building codes.…”

It is evident that, due to population growth, future urbanization and urban growth are inevitable. It is estimated that the food supply demand of future urban centers will grow, which will place an additional burden on the agriculture sector to produce more food. It is projected that securing the food supply chain for future urban centers will be a challenge. Urban agriculture can be regarded as a remedy for possible future challenges that the global food system will face. It might be able to reduce the future burden on the agriculture sector. This research proposes that urban rooftop agriculture, as a subset of urban agriculture, can produce local fresh food in dense urban environments. The principal aim of this research is to suggest a series of design recommendations for architects interested in designing residential buildings capable of rooftop food production. This research attempts to highlight the specific design recommendations and the principal limitations regarding designing residential rooftop farms. To extract the data for developing the proposed design recommendations and limitations, a review of the literature within the fields of urban agriculture, building-integrated agriculture, and horticulture was conducted. Based on the literature review results, this research suggests that the following three types of farming methods can be developed on residential rooftops: (1) open-air rooftop food production, (2) “low-tech” rooftop greenhouses, and (3) “high-tech” rooftop greenhouses. In addition, factors that can be considered principal limitations are suggested. In sum, this research proposes that current and future residential buildings can be designed so that their rooftops are utilized as farms. In this way, such buildings can contribute to delivering local fresh food to current and future metropolitan dwellers.

“…To sustain environmental quality, it is becoming increasingly crucial to restore green places [ 79 ], and green roofs can help promote the restoration of urban green spaces and improve air and quality of life [ 80 ]. Therefore, green roofs are a potential solution for sustainable urban development [ 81 ]. Achieving sustainability in green roofs requires, firstly, the selection of plant types with high survival rates; secondly, it is important to choose sustainable irrigation systems [ 82 ].…”
