Education & Medical District
The Graduate Urban Design Studio at Carnegie Mellon University, USA explores urban design scenarios and the creation of urban design guidelines for a new mixed-use district within Lusail City, an expansion of the city of Doha in Qatar. Focusing on sustainable urbanism and the role of guidelines in urban design, the studio explores how urban design can shape contemporary globalized development practice to respond to social, cultural and environmental factors specific to Doha and the Persian Gulf region. Using the methodological tools of urban rule, code and guideline, the project investigates how urban design can mediate between the scale of planning and infrastructure and that of the individual development while balancing environmental performance and urban form definition, architectural expression and formal unity, and modern architectural languages and cultural traditions. The studio worked in partnership with Qatari Diar Real Estate Investment Company, the owner and master developer of Lusail City. Currently under construction Lusail will be a new costal city adjacent to northern edge of Doha. In the major infrastructure construction phase, Lusail is seeing the first buildings come out of the ground in the Marina district in the city’s south west corner while utility and transportation infrastructure is being developed on the rest of the site. Organized as walkable transit oriented city, Lusail is served by a hierarchy of roads, a bicycle and open space network and both a city wide light-rail system and a line of the proposed Doha Metro.
Many aspects of the Lusail masterplan are well considered and laudable, however like many other contemporary Gulf region developments, the plan is based heavily on normative Western development and infrastructure design practices. In many cases these assumptions work well, creating a modern functional city, however some aspects of the design fail to respond to environmental factors and cultural traditions in a nuanced way, especially in the scale and occupancy of the public realm in a desert climate, and the balance between global development trends and cultural specificity. As the plan moves towards implementation Qatari Diar is working to advance the design and address issues district by district at an urban design scale. This urban design studio has tried try to push this discourse forward by focusing on the mixed-use Education and Medical District which had not been studied at a detailed urban design scale. The Education and Medical District is slated to contain a cluster of schools, a hospital and medium density residential. The existing framework of general infrastructure, density and program has been adopted, and these constraints have been used to test multiple organizational and massing strategies on the site, ultimately choosing and developing a preferred direction. Finally a set of urban design guidelines has been generated and parametric modeling tools have been used to test and iteratively refine a set of final guidelines. This is the final product of the studio summarizing the work.

2.2 Local Context - Lusail City Lusail is a new waterfront city, located 30 km north of Doha. Lusail will be a complete mixed-use city including multiple residential districts, a major retail district, multiple office districts, a golf course and a network of new parks connecting all parts of the city to the waterfront. Unlike much recent development in the Gulf region, Lusail has been concieved of as relatively compact walkable place served by an internal transit system and connected to central Doha by a new subway. Lusail is a project of QATARI DIAR a real estate development company founded to support Qatar’s rapidly expanding economy and to provide structure and quality control for the country’s real estate development priorities. When complete Lusail will ultimately be a seperate municipality from Doha.

3.1 Site Conditions Analysis The existing master plan has been analyzed in terms of its strengths, weaknesses and constraints.
M M
Strengths: The district design, location and proximities provide tremendous opportunities in creating a well defined urban environment. The existing LRT system, proximity to the highway, green infrastructure and wind; all contribute in enhancing the quality of the living environment. Weaknesses: The highway is also a potential threat causing high air and noise pollution, which are directed towards the site through dust storms. Currently, there is a limited access to the district resulting in long street edges without entrances. Constraints: Certain design constraints were provided by Qatari Diar in accordance with the masterplan. These include the existing green utility corridors, the LRT street, the Crescent park. The district cooling plant was to be located in proximity to the commercial boulevard.

Landuse scenario one was chosen after initial discussions with Qatari Diar. The residential uses forms the core of the development, surrounded by school and medical uses on either side. Integrating the residential district to the commercial boulevard opens up the district edge and promotes walkability. It also supports the idea of integrating the character of Ed+Med district with overall Lusail Masterplan. Locating hospitals along the highway keeps noise and disturbances away while also providing ease of access by limiting the hospital traffic to the periphery. The Schools are situated along the edge of Crescent park. The open spaces of the school assist in physically and visually relating to the larger open space network of Lusail.

3.3 Density Analysis A final step in the anlysis tested the density of the given program using a variety of residential typologies. Three options for densities and FAR were analyzed. The GFA as specified in the documents was first tested using a combination of building footprints. The existing GFA was insufficient not only in terms of its relation to the surrounding built environment but also in terms of providing a walkable, pedestrian friendly and shaded environment. Densities as high as twice the existing GFA were tested and even that was not as compact and dense, especially when compared to the adjacent Al Erkyah residential development.

4.2.1 Existing District Landuse Plan The existing landuse for the masterplan has the residential program along the highway away from the Crescent Park. Schools and hospitals are placed on the east side of the LRT corridor, hospitals along the edge of commercial boulevard and schools along the crescent park. The scheme intergrates with residential program within the surrounding context.

4.2.2 Proposed District Landuse Plan
The residential uses forms the core of the development, surrounded by school and medical uses on either side. Integrating the residential district to the commercial boulevard opens up the district edge and promotes walkability. It also supports the idea of integrating the character of Ed+Med district with overall Lusail Masterplan. Locating hospitals along the highway keeps noise and disturbances away while also providing ease of access by limiting the hospital traffic to the periphery. Schools are situated along the edge of Crescent park. The open spaces of the school assist in physically and visually relating to the larger open space network of Lusail.

4.2.3 Existing District Masterplan The existing master plan has been designed for ease of vehicular movement. The street right of ways are wide with large turning radii which makes its difficult for pedestrians to navigate. Few street grids do not currently align to neighbouring streetways. These factors have lead to lack of clear hierarchy of movement within the district. The linear green fingers currently function as isolated medians providing no more than visual comfort. The residential block sizes in particular need to be reduced in order to promote walkability.

4.2.4 Proposed District Masterplan The Educational and Medical District has adopted an integrated interdisciplinary approach to the master plan where it combines landuse, builtform and open spaces to bring about greater densities and to create areas of high value and accessibility. The proposed plan uses a smaller block structure with narrower street right of ways favoring ease of pedestrian movement across the district. A pedestrian pathway within the blocks serves as a north- south movement corridor. The linear green fingers have been integrated into the blocks so as to provide better access to the valuable open space.

4.2.5 Vehicular Circulation & Road Hierarchy The design strategy has been to develop a network of narrow, well shaded and human scale secondary streets throughout the district. A clear hierarchy of street types has been established, ranging from the high speed highway connecting Lusail, to the narrow streetscapes for access to individual plots. The street grids have been aligned to the commercial boulevard and dedicated streetscapes have been designed for both hospital and school uses.

4.2.6 Non-Vehicular Circulation For pedestrian circulation system, the aim is to create shaded pedestrian paths that connect users to transit stations. The central pedestrian spine divides the blocks into smaller zones within the residential district, thus enhancing the walking experience and also creating a comfortable microclimate within the blocks. The intent has been to design all streetscapes to be pedestrian oriented and highly walkable. A network of bike paths further enhances the travelling experience.

4.2.7 Open Space Strategy The Open spaces for the district have been designed using two strategies. The first strategy is to relate to the surrounding context while capitalising on the existing assets. These include integrating green fingers within the development leading to the larger open space network of the Crescent, creating views from the residential units, schools and hospitals. The next strategy is to use shaded pedestrian pathways instead of large open spaces as a way to create a highly activated public realm. The north-south linear pedestrian connection also acts as a breezeway due to its alignment along the prevailing wind direction.

4.3 Street and Building Typologies Understanding various Street and Building Typologies in relation to Doha is another important part of the study. Street typologies study includes comparison of streets from the existing master plan with other case projects built in the same region. These studies clearly suggest that the right of ways as currently designed for the district are enormous and have been laid out mostly favoring high speed, free moving vehicular traffic. This contradicts with the overall vision established for Lusail, which is to provide a highly walkable and pedestrian friendly human scale environment. Therefore, as a part of the design proposal, a hiearchy of streets has been created, walkable and shaded environment is encouraged in the public realm. A wide range of possibilities of building types were studied, however the report includes only the ones that have been regulated as they are more appropriate to climate and density considerations of the project. Building Typologies study is important and have been regulated as a part of the Urban Design Guidelines for the district. This has been done primarily for better solar and wind performance but also to define the public realm having varying densities.

4.3.1 Existing Road Hierarchy Sections The existing streetscape layout and typologies of Ed + Med district have been developed to be integrated into the wider network of overall masterplan and in general, have been designed for easy and free moving traffic.
a. Primary Road (50 M) The street section is wide and governed by automobile traffic. Absence of turning cuts over long distances causes wastage of energy and time. Placing the LRT on the central median discourages pedestrians to actively use it because of its poor accessibility. The street intersections are particularly difficult to navigate through safely – both for pedestrians and bikes. Free right turning lanes allow ease of traffic movement but work against providing a pedestrian friendly environment.
Key Plan

b. Seconday Road (40 M) The secondary streets in this district are also designed as high speed roads with large green medians acting more as a visual gesture rather than providing shade. Absence of any separate bike paths contradicts with the city’s overall goal of promoting walkability and sustainability.

4.3.2 Proposed Road Hierarchy Sections The proposed vehicular circulation is based on a a system of road hierarchies which has been used consistently across the district. The streets have been modified to suit the surrounding development they support, and have been designed as complete streets, streets which are equally favorable to vehicular and pedestrian movement.
a. Primary Road (50 M) The primary goal for the street was to respond to human scale and to provide an inviting atmosphere equally for all users. Existing right of way width was fixed but modifications to the street section have been done. Light Rail has been placed on residential side of the street to provide easy access for residents. 10m building setback has been eliminated in order to define street edge. Green median has been equally divided on either side of road, integrating green space with pedestrian movement system. Bike lanes have been added and a semi covered shaded pathway along edge of the blocks has been regulated. One left turning lane is provided instead of two.

Urban Design Guidelines
Overview This chapter explains the Urban Design Guidelines as a means to establish parameters for comprehensive development of Ed+Med District. These guidelines create a clear set of design goals to control massing, density, street edges and perception of the public realm. They establish two levels of control: performative and non-performative. They have been organized into three categories: character zone specific, subzone specific and block specific. The chapter ends with performative analysis of massing options generated as per the guidelines and some illustrations indicating the quality of the built urban environment.

5.0.1 Urban Design Principles
3. Provide adequate Solar and Wind Access for Buildings
Urban Design Principles explain the types of rules and motivations behind them using a series of diagrams and written principles:
Prevailing Wind Direction
1. Define and delineate the public and private realm through building facades on block edges while enabling flexibility inside the blocks. Flexibility Within the Blocks
Buildings defining the public realm
Prevailing Wind Direction is North-East.
2. Maximize vehicular and pedestrian connectivity for all users.
Wind should be channalized through public realm.
4. Provide Shade and Breeze for the public realm.

5.0.4 Things that are Regulated The Urban Design regulations have been formalized keeping in mind two major goals for the district design. The regulations on one hand aim at directing density, massing in order to define street edges, promote walkability and enhance the public realm. In addition, they also aim at improving the performative quality of buildings and public spaces in terms of providing good solar access and wind.

5.0.5 Categorization of Guidelines The Urban Design Guidelines in the report have been organized into three major categories. Any developer or designer working on any piece of land within the district has to follow the rules in all three categories, whatever is applicable to that particular parcel. The rules have been categorized into three hierarchal levels based on the scale. Character zones first break up the district into 6 categories with specific characters. Every character zone is then divided into sub zones having varying densities, massing and performative rules. Finally, specific rules have also been written for blocks having peculiar characters or elements forming the public realm.

a. Core Residential District
c. North Residential District
Core Residential District is located along the LRT street, a major transit corridor connecting the district to commercial boulevard and other districts within Lusail. It forms the core of the whole development surrounded by school and hospital facilities on either side. This is the largest and one of the most important character zones in defining the urban built environment of the district
N
North Residential District is bounded by the high density Al Erkyah district to the north, the LRT corridor on the east and the highway to the west. This district comprising of essentially one block is comparatively higher density residential development. Proximity to Al Erkyah, LRT stop and the highway make this character zone peculiar in terms of real estate value as well. N
b. South Residential District
d. School district School District has been located long the Crescent park as a way of physically and visually connecting to the larger network of open spaces. The density within the district has been pushed towards the west and recreational facilities form the eastern edge of the district.The schools are accessed through an internalized street system designed for easy pick up and drop off.
South Residential District is located in close proximity to the main commercial boulevard. This character zone has been designed as to relate to the character and scale of development across the street. Easier pedestrian connectivity across the district, additional pedestrian pathways and proximity to the crescent park make this character zone unique in itself.

e. Hospital District Hospital District is located at southwest corner of the district bounded by the highway on the west and LRT corridor on the east. This district is envisioned to add a more dynamic character to the highway edge along with Qatari Diar office tower to the south. The isolated location helps segregate hospital traffic from rest of the district traffic system. Density has been pushed along LRT corridor in order to form a street edge. Hospital Residential fall within northern part of the zone. N
f. Civic Facilities Civic Facilities have been strategically located at the termination point of two major streets connecting the district to larger city networks. Facing the crescent park, this has been envisioned as a highly active public zone forming the core of civic and recreational activities. Apart from having libraries, museums and retail activities, it also houses a Friday (Juma) mosque with a huge public square overlooking the Core Residential District.

Civic Facilities Zone Civic Facilities have been strategically located at the termination point of two major streets connecting the district to larger city networks. Facing the crescent park, this has been envisioned as a highly active public zone forming the core of civic and recreational activities. Apart from having libraries, museums and retail activities, it also houses a Friday (Juma) mosque with a huge public square overlooking the Core Residential District.
N
121
There are no specific rules for Civic Facilities Zone, instead a design proposal has been given. According to this proposal, mosque is located at the end of pedestrian pathway view corridor in order to create a focal point. The retail activities, museum and community center are designed between the square and the LRT Stop. A high canopy is placed both to create a grand gesture and to create a shaded and walkable public space. The public library, on the corner of main vehicular road, is envisioned as being a landmark.

Performative Analysis
Overview This section presents a a performance analysis of massing examples generated on the basis of the guidelines. Doha has a harsh climate, especially in summer months. The guidelines in the previous section have been written based on thermal comfort considerations of users in buildings as well as outside. This section tests different massing strategies within the written guidelines in terms of their response to solar and wind performance.
125
6. 1 Massing Examples of Two Blocks Three varied massing examples were generated to test the flexibility of urban design guidelines. All the three examples vary tremendously in the way the building typologies have been selected and oriented. Different types of public realm are created in different schemes. These examples have then been used to test the performative goals as prescribed in the guidelines.
a. Plan Views Option 1 represents an orthogonal massing strategy. Although orthogonality may not be the best option in terms of providing thermal comfort in buildings, it provides enough access to wind and adequate solar orientation.
Option 1
Option 2 represents more flexible massing. As can be seen, the main pedestrian pathway can be more flexible to create different perspectives while walking through it.
Option 3 explores the most flexible massing scenario of the three. The ground and first floors are designed orthogonally to the block while upper floors have been oriented to cool the interiors.

Area overshadowed for 3 hour between 5am & 6pm
The solar analysis has been done for June 21, that is worst time of the year in terms of solar heat gain. The time duration between 10 am and 2 pm has been excluded from the benchmark established for best shaded zones.
Area overshadowed for 4 hour between 5am & 6pm Area overshadowed for 5 hour between 5am & 6pm Area overshadowed for 6 hour between 5am & 6pm Area overshadowed for 7 hour between 5am & 6pm
Main pedestrian road crossing through residential parts should be shaded
One side of Green Fingers should be shaded
Area overshadowed for 8 hour between 5am & 6pm Area overshadowed for 9 hour between 5am & 6pm
E-W Long Axis is appropriate for minimizing the solar heat gain of the buildings
Narrow Alleyways are more likely to be shaded most of the day

b. Solar Analysis of 3 design possibilities
Option 1 represents an orthogonal design. It provides enough access to wind and adequate solar orientation.The main pedestrian road is totally shaded for most of the day. in summer. This option performs the best of the three in terms of providing thermal comfort
Option 2 represents more flexible design within the rules. The LRT Corridor is shaded and so are courtyards and primary pedestrian pathways. One side of green finger is shaded to create a walkable open space.
Option 3 represents most organic design of the three. Ground and first floors are oriented to channel the wind through public realm while upper floors are oriented according to solar and wind considerations. This option performs the worst of the three in terms of providing thermal comfort.

Architectural Guidelines
Overview Architectural guidelines aim to ensure that architectural style, building form, material and shading strategies are relevant to the culture and climate of Doha, and also assist in giving the site an appropriate identity. These are more towards being suggestive than being prescriptive.
