Over the past twenty years, rapid urbanization in Dubai has fundamentally changed land use. This has necessitated significant infrastructure development to meet the needs of the growing urban population. Therefore, this study examines changes in public satisfaction with the Dubai Metro between 2010 and 2018. Surveys were conducted at eight strategically selected metro stations, with 400 respondents at each time point, to evaluate six core factors, which are usage, cost, facilities, challenges, contextual integration, and walkability. Statistical analysis, including Chi-square tests, revealed significant shifts across all factors. Daily metro usage increased by over 10%, indicating growing reliance on the system, while perceptions of affordability declined, with twice as many users finding fares expensive in 2018. Satisfaction with station facilities and contextual integration improved substantially, reflecting successful investments in infrastructure and urban planning. However, accessibility and external walkability emerged as growing concerns, underscoring the need for enhanced pedestrian connectivity and inclusive design. The findings offer actionable insights for transport policy and urban development for Dubai and underscore the importance of continuous feedback in shaping public infrastructure.

Walkability ratings in the GCC are generally low. Beyond climate conditions, modern lifestyle shifts such as increased reliance on automobiles, home deliveries, remote work, and digital connectivity have contributed to the decline of walking as a primary mode of transport. While previous research has identified urban design factors that influence walkability, there is limited empirical evidence on how these factors operate within Dubai’s unique urban context. This paper investigates the impact of urban design on perceived walkability using objective site analysis. Based on a review of the existing literature, Ewing and Handy’s model was selected for its strong explanatory power; accounting for 95% of walkability variation across five key urban design factors: Imageability, Enclosure, Human Scale, Transparency, and Complexity. The model also identifies Human Scale as the most significant factor influencing walkability, which informed the study’s hypothesis that Human Scale would emerge as the primary predictor in the selected sites. Notably, Complexity consistently emerged as a strong predictor, underscoring the importance of spatial diversity and visual richness in enhancing pedestrian experiences. An objective built environment analysis was also conducted using Ewing and Handy’s field guide to assess the five walkability factors across the selected sites. This analysis highlighted which sub-factors, such as landscape features, positively contributed to walkability. However, it also revealed the assessments, particularly in how each site ranked across the design factors. The findings affirm the relevance of Ewing and Handy’s model in assessing overall walkability; however, they also suggest that additional variables may be needed to fully capture the dynamics of walkability in Dubai’s urban context. While the model identifies Human Scale as the most significant factor, an insight that shaped this study’s original hypothesis, the results reveal that this may not hold true uniformly across all locations. Instead, Complexity consistently emerged as a stronger predictor, emphasizing the role of spatial diversity and visual richness in shaping the pedestrian experience. These insights offer valuable guidance for urban planners and policymakers aiming to enhance walkability, particularly in the design and development of low-rise areas intended to attract pedestrians.

In Dubai’s rapidly expanding urban landscape, addressing the adverse impacts of increasing automobile reliance is critical. Growing vehicle usage contributes to urban sprawl, prolonged commutes, infrastructure strain, and diminished green spaces. As a sustainable alternative, Transit-Oriented Development (TOD) promotes compact density, mixed-use environments, and transit-focused design, particularly suited for Dubai’s evolving context. This study evaluates the applicability of Transit-Adjusted Development (TAD) and TOD appraisal models, specifically the 3D and 6D frameworks, to stations on both the Red and Green Lines of the Dubai Metro. By examining Dubai’s complex urban form, the research identifies strategic interventions to enhance urban mobility and mitigate sprawl. Through an extensive literature review, key factors shaping sustainable urban transport such as accessibility, land-use diversity, density, design, distance to transit, and demand management are analyzed. This investigation highlights the suitability of implementing TOD principles at prominent metro stations, including Al Rashidiya, Al Qusais, and Mall of the Emirates. These stations hold significant potential for strengthening transit efficiency, fostering pedestrian-friendly neighborhoods, and reducing dependency on private vehicles. The findings underscore the importance of integrating TOD strategies into Dubai’s metropolitan planning. By doing so, Dubai can move toward a more connected, efficient, and environmentally responsible urban future.

Indoor landscaping is an environmentally friendly approach that enriches the environment and fosters productivity and comfort for occupants. The practice of incorporating plants into interior spaces requires meticulous care to ensure healthy growth and prolong the benefits of interior greening. This study explores the impact of natural and artificial light, represented by fluorescent lighting on the growth and physiological responses of Codiaeum variegatum and Ardisia japonica. A natural light chamber and an artificial light chamber of identical dimensions were constructed to compare the plants’ physiological responses under consistent temperature, humidity, and illuminance conditions. The results indicate that Codiaeum variegatum and Ardisia japonica exhibited higher chlorophyll content and photosynthetic rates under natural light conditions compared to fluorescent lighting. Furthermore, the study found that natural light offers a rich spectral distribution across various wavelengths, providing an advantage for plant growth. Although direct comparisons between natural and artificial light environments are inherently challenging due to the distinct characteristics of each light source, the study emphasizes the importance of considering the rich spectral distribution of natural light when designing artificial lighting systems for optimal plant growth. In conclusion, understanding the effects of natural and artificial light on indoor plants is crucial to supporting plant growth and creating more effective indoor gardening solutions. Although direct comparisons between natural and artificial light environments are inherently challenging due to the distinct characteristics of each light source, natural light provides a more advantageous environment for growth compared to fluorescent lighting, with Codiaeum variegatum and Ardisia japonica both exhibiting a higher chlorophyll content and photosynthetic rate under natural light conditions.

According to UAE Health Ministry and Dubai Healthcare City reports, 15% of Dubai residents have a chronic respiratory disease such as asthma. Moreover, 90% of the 150,000 patients at Al Ain Hospital suffered from upper respiratory tract respiratory diseases, bronchitis, or asthma. Sick Building Syndrome (SBS) has emerged as a social problem in the United Arab Emirates (UAE). The Dubai Municipality regulates Indoor Air Quality (IAQ) with strict stipulations before moving in, but they are relatively passive about regulations related to healthy living. This paper aims to explore the actual state of perception of the IAQ from townhouse residents in Dubai, UAE. The characteristics of the resident’s perceptions of the IAQ are identified, and the influential factors affecting residents’ perceptions of IAQ are extracted. As a methodology, the survey was conducted on four townhouse projects in Dubai from December 2021 to January 2022. A total of 114 copies were distributed, and 98 documents were used. Analysis of the survey data was processed using IBM SPSS Statistics 26.0. The results showed a statistically significant correlation between the cognitive and anxiety levels of SBS with the presence or absence of experience. It was statistically confirmed that the most influential factors were the age of the children and the occupancy time of housewives and children. This is because of the perception that wives who spend a relatively long time in the house and their young children are exposed to indoor air pollution for a long period of time and are easily affected by this influence on the concerns about young children about SBS. Ninety-five percent of the respondents answered that they knew more than average about SBS, indicating a very high level of awareness. As for the degree of anxiety, 87.0% of the respondents felt higher levels of anxiety than usual. However, most of them did not know or were indifferent to the understanding of the air quality improvement methods. The awareness of actual contents was lower than that of residents who assessed that they knew about SBS.

This study investigates the tourism-oriented heritage districts in the United Arab Emirates (UAE) and explores a new approach to fostering heritage tourism. This is envisaged through conducting a post-occupancy evaluation (POE) to detect the characteristics of the tourism-oriented heritage districts from the residents and tourists. The systematic evaluation of opinions is based on indicators developed by UNESCO and ICOMOS international principles. According to the survey results, it is found that Dubai’s approach was successful at reuniting people with their history via modern materials in the restoration works. This has preserved the heritage value and increased their culture and national identity. The social goal to reconnect residents to their cultural history has been realized despite the inconsistencies compared to the specification of the World Heritage Convention, which requires technical authenticity and integrity. People perceived the identities of tourism-oriented heritage districts in Dubai, Sharjah, and Ajman differently. Based on the POE survey, the Shindagha area and Al Fahidi Historical Area in Dubai were perceived as traditional destinations for tourist attractions. The Heart of Sharjah area was perceived as cultural and educational tourism, and the Ajman Heritage District area was perceived as community tourism.

The Urban Heat Island (UHI) has a detrimental impact on human thermal comfort and the health of city dwellers through raising average temperatures. Urban geometry is one of the factors that affect the intensity of the UHI phenomena. The purpose of this research is to evaluate and compare traditional vs. modern urban forms with respect to temperature and thermal comfort in the United Arab Emirates. Three of each were chosen based on their densities and form. Traditional buildings in the UAE differ from others in the Middle East in that they are primarily single-story, while in the surrounding countries of the region, such as Iran, Iraq, and Saudi Arabia, they are mainly two stories. The UAE climate also has its distinct characteristics. Each configuration was investigated using the ENVI-met urban microclimate simulation software. The comparisons were made for three seasons: summer, winter, and spring. Each configuration was evaluated through four parameters: building shape, street geometry, orientation, and urban density. The results revealed that the low-density traditional urban form exhibited the lowest air temperature in August because it has a low sky view factor (SVF), high height-to-width ratio, and less density. The highest ambient temperature was observed in the sites with low-medium density, lowest height/width ratio, and maximum SVF. The high-density modern urban form displayed lower air temperatures in the summer season than the low and low-medium-density modern urban sites due to the building form, high height-to-width ratio, low SVF, and wind corridors. The traditional compact urban form in Al Fahidi, which has the highest urban density of the six configurations, achieved the best thermal comfort levels in the summer due to the sizable height-to-width ratio and lowest SVF.

The population of Dubai has increased dramatically in the last 40 years. Along with social changes, neighborhood parks are becoming increasingly important for enhancing the residents’ quality of life. This study aims to evaluate the physical environment of parks and investigate park users’ satisfaction in neighborhood parks of Dubai. After defining the park and surrounding environment for access, a field survey was performed at Bay Avenue Park and Al Ittihad Park. The data for analysis were collected from the Department of Geographical Information System (GIS) Center at Dubai Municipality. The results show that the standard duration was 60–90 min, and the walking/driving time was 10–20 min. “Children Facility” and “Various Attractions” were low in both parks. The statistical results of multiple regression analysis of the derived factors and satisfaction show that Bay Avenue Park influenced satisfaction in the surrounding environment for access, pedestrian space, park facility, convenience and comfort of the park, and various attractions and activities. Furthermore, Al Ittihad Park influenced satisfaction in pedestrian space, green landscape, surrounding environment for access, park facilities, and safe access. Therefore, factors such as park facilities, surrounding environment for access, and pedestrian space were analyzed to affect satisfaction in both parks. The analysis of the surrounding environment for access factors using GIS would methodologically help determine priorities for future improvements around parks. However, this study is limited by the scope and investigation period of the target parks, and detailed factors related to the surrounding environment for access are also not evaluated.

Children inhale indoor air at 400 mL/min∙kg per body weight, 2.76 times more than adults. They have weaker immunity than adults and are more exposed to asthma, allergies, and atopic diseases. The objective of this paper is to suggest effective management and improvement measures for indoor air quality for nurseries. As a methodology, 16 nurseries (total of 35 classrooms) were selected to measure the indoor air quality compared with WHO IAQ Standard, and identify the daily concentration change of the pollutants. Based on the measurements, IAQ improvements for selected facilities are carried out to compare the results before and after improvement. The result has shown that the concentration of Carbon Dioxide (CO₂), Total Volatile Organic Compounds (TVOC), Total Suspended Particles (TSP) and formaldehyde (CH₂O) exceeds WHO IAQ standards. The concentration of CO₂ and TSP is changed mainly by physical activity of children and that of CH₂O and TVOC is changed mainly by ventilation after school start. TVOC decreased by 46.4% and the TSP decreased by 21.7% after air purifier, but CH₂O and TVOC increased 1.8–3.8 times after interior renovation with low-emission finishing materials. After new ventilation installation, the CH₂O and TVOC reduced half and the TSP reduced one third. It is proven that the most effective way to reduce the concentration of air pollutants in nurseries is the installation of a new ventilation system, followed by an air purifier. The renovation with low-emission finishing materials cannot improve IAQ in a short period of time.
