Generating sustainable form-based urban design strategies for an integrated neighborhood

textI conducted a case study analysis of Dubai, exploring multiple urban design tactics for a more sustainable development approach to Dubai’s pattern of development. Particularly, this dissertation identifies sustainable urban form design principles and strategies for a Dubai neighborhood. The research addresses the question: which form-based urban design strategies effectively deliver greater environmental, social, and economic coherence in Dubai’s neighborhood development? In addition, this research addresses the question of whether certain urban form design principles contribute comparatively more than others to sustainability. I used two rounds of the Delphi technique, a structured communication technique utilizing multiple rounds of questioning, to obtain experts’ knowledge and opinions to redefine urbanism in Dubai towards more ecological and social responsive practices. My analysis of the Delphi reveal that in Dubai, the most sustainable neighborhoods are those emphasizing more public participation in the initial planning process, i.e., connectivity and multiple transportation options; adequate diversity; green, open, and social nodes in the urban fabric; culturally-relevant urbanism and architecture; climate-sensitive urbanism and architecture; eco-balanced design applications; and adaptability, all integrated with one another in the compactly arranged urban fabric. Approaches to sustainable development must stress elements other than just design itself, such as grasping the nuances of the cultural traditions, politics, and implementation constraints. Therefore, this research also involved collecting survey responses from local and expatiate residents in Dubai and interviewing Dubai government officials in order to identify and to understand the relevant political and cultural aspects as well as obstacles associated with the experts’ design recommendations. In particular, survey responses were used to: (1) identify the public opinion surrounding some of the Dubai neighborhood design ideas suggested by an international and local panel of experts; and (2) understand how the public value and prioritize the suitability of the proposed design strategies to Dubai’s cultural environment. Interviews with the local authorities in Dubai facilitated (1) the determination of troublesome challenges and constraints for implementing some of the urban design strategies defined by experts in the Delphi; and (2) identification of implementation opportunities and possible policy initiatives that might support the implementation of the proposed strategies. I also synthesized all research data to identify areas of overlap and disagreement among research participants (the experts, public, and government officials). Finally, the last chapter discusses two major obstacles challenging different aspects of sustainability. I also detail a potential solution to prevail over the challenges, and introduce potential areas of future research.Community and Regional Plannin

Sustainable neighborhoods. An energy analysis at urban scale on 5 different typical districts of Abu Dhabi Main Island.

By the passing of the years, the world population is concentrating in the cities converting natural areas into urbanized areas by modifying also the thermal properties of the area. The local climate is under continuous change while the cities evolve. And this change is shown perfectly in the Urban Heat Island (UHI) phenomenon. The cooling load inside the buildings is increased indirectly by the UHI phenomenon. This would bring additional cost and bring one step back into the main target of having a sustainable city. Sustainable city start with sustainable neighborhoods. This paper provides an overview on how with the help of different tools such as ENVI-met, UMI, Energyplus and Ecotect we can have the results of the energy consumption of 5 different districts in Abu Dhabi, a city with hot arid climate. The idea is to analyze each district that is characterized by different building typology. On a second step, after using Ecotect to locate the areas that were exposed to the sun within the district there is an intervention proposal. Placing urban shading devices and vegetation in form of parks not only would improve the outdoor quality but also can reduce the cooling load in the building by reducing the temperatures and improving the airflow. This is the main aim of this study. Several simulations before and after the proposals will show this energy saving. The shading devices proposed are complying with the traditional concept but adapted to a new technology. The main material would be wood and a specific type of fabric. Even though for the tools used in the energy simulations the important parameters are connected to the materials only. Special openings and details are not recognized. Even though, thru the two main tools we can show that requalifying the neighbors bring direct and indirect savings and helps in having a sustainable neighborhoods

A Grid Is Not a Tree: Toward a Reconciliation of Alexander's and Martin's Views of City Form

Christopher Alexander famously declared that "a city is not a tree," while Leslie Martin declared that "the grid is [a] generator." This article investigates how Alexander’s call for overlap, adaptability, and order can indeed be manifested in grid networks, as Martin claimed. Order has been measured using the entropy of street orientation, while adaptability has been denoted by the streets' betweenness values. Through the analysis of Abu Dhabi's neighborhoods and global urban areas, the study reveals that overlap, order, and adaptability can coexist in gridded street network. A fine-grain scale of the grid plays a critical role in supporting the quality of urban space. To foster adaptation, planning policies should focus on adaptability providing room for informal and spontaneous growth. We conclude by noting that this approach represents a reconciliation between Christopher Alexander's views and those of Leslie Martin

Making religious buildings more accessible: The case of mosques in Abu Dhabi’s and Dubai’s neighborhoods

More than a house of worship, religious buildings have a critical and authoritative role in the social and political life of people. Yet, such places of divine and spirit have received limited attention in transportation and urban planning research. This research evaluates accessibility to one kind of religious institution: mosques. The article studies the ease of access to mosques at walkable distances of 400 m and 800 m radii in twelve selected neighborhoods in Abu Dhabi and Dubai. Analysis uses the gravity metric under two network scenarios: streets only, and the combined network of streets and alleys. Gravity values demonstrate three types of accessibility to mosques: plots without access, plots with minimum access to one mosque, and plots with choice access to more than one mosque. Findings show neighborhoods have experienced an erratic decrease in accessibility to mosques. In both cities, percentages of plots with an overall accessibility to mosques, (sum of both minimum and choice), were higher in the pre- and-early-suburban phases. With the inclusion of alleyways, the overall accessibility percentages increased in many cases. The study reveals that good pedestrian accessibility results from an effective interplay between street design, plot densities, network intersection density, strategic placement of alleys, and mosques’ ratio and spatial distribution

Title: Post-pandemic planning: Do we have enough and efficient access to parks?

Introduction: The COVID-19 pandemic has placed neighborhood parks as a key asset in mitigating the negative implications of extended lockdowns, when parks turned into a sanctuary for residents. With increased scholarly work focusing on developing pots-pandemic neighborhoods, providing access to community parks via efficient routes, is central to such debate. Network connectivity provides a comprehensive assessment of the efficiency of network systems.Methods: A total of 16 samples, from the city of Abu-Dhabi, have been selected to study their network connectivity, with regard to accessing parks. Three distance-based connectivity measures are used: the pedestrian route directness (PRD), the count of redundant routes Redundancy Count (RC), and the route redundancy index (RI). The samples reflect different street’s typologies and their urban form attributes are quantified.Results and Discussion: Connectivity analyses results are interrupted with regard to the quantified physical attributes. Findings indicate that gridded, and semi-gridded layouts provide more direct routes to parks, but less route’s redundancy. Conversely, interlocked, and fragmented networks, when having sufficient intersection densities, have less direct routes but more redundancy. The inclusion of alleyways proved to alter typologies into gridded ones and improve both route directness and redundancy. The majority of the selected samples reported sufficient levels of route directness. The current design and planning guidelines, implemented by the Department of Transport and Municipalities are overly descriptive with regard to how neighborhood parks are accessed; therefore, the study’s methodology provides a possible more evidence-based approach to policy development

Influence of the Built Environment on Physical Activity Choices among Emirati Male and Female Adolescents: An Examination of Parents’ and Students’ Perceptions

The UN Human Development Report 2020 ranked the United Arab Emirates (UAE) as having achieved ‘very high human development’ and as being at the 31st position among all countries. Despite this, the ever increasing obesity rates among Emirati youth, higher than international standards, is alarming. This research aims at identifying how different perceptions of the built environment by parents and adolescents are likely to affect physical activity (PA) choices among male and female Emirati youth. This can help inform better health and education policies to achieve three of the interconnected UN Sustainable Development Goals (SDGs), namely good quality health and well-being, quality education, and gender equality, that the UAE strives to achieve. Responses from 335 students (aged 14–20) from six schools and 250 parent responses in the Al Ain region of Abu Dhabi Emirate were used to understand the mean variation in perception of five built environment constructs. Further, multinomial logit regression was used to assess the health condition using the perception, behavior, and built environment measures. Results indicate that Emirati males perceive the built environment factors as barriers more than female adolescents. Parents perceive street crossing (p p < 0.020) to be more of a hindrance. Traffic exposure, self-reported physical activity, and walkability near homes and schools significantly affect Emirati adolescents’ health conditions. Recommendations are made for various stakeholders including parents, school authorities, Abu Dhabi Municipality and Transportation, and the Urban Planning department on ways to enhance the built environment and encourage PA and well-being of Emirati adolescents

From local to global: Uniting neighborhood planning units for more efficient walks

This study examined the critical but scarcely analyzed topic of integration in neighborhood planning units (NPUs) by analyzing local and global integration across 12 distinct NPU network designs in Abu Dhabi, including two different suburban phases. Utilizing pedestrian route directness (PRD) and Betweenness centrality as analytical tools, this study conducted an analysis covering four specialized tasks, each representing a distinct aspect of a trip ranging from a local to a global scale by using streets only and streets with alley scenarios. The results showed that global directness in NPUs notably outperforms local directness in street-only analyses, challenging longstanding beliefs regarding inherent NPU segregation. Furthermore, the study categorized grid networks as comprising concentrated centrality, whereas fragmented and interlocked networks exhibited dispersed centrality. After incorporating alleys into the analysis, an enhancement of street directness was observed across all networks on the local and global scales. In addition, the alleys exhibited centrality dispersion across all tested networks, along with a slight increase in centrality concentration in the selected segments. This study develops an initiative for improved neighborhood planning by promoting a more comprehensive understanding of global NPU integration
