School Work“Option Studio�, 2018 George Baird Urban Design New Vision for Villiers Island Toronto, Canada N/A Individual Work Revit, Rhino, Photoshop, Illustrator

The studio project focused on issues that are in the design of the currently underway between Waterfront Toronto and its corporate collaborator Sidewalk Labs. The output of the studio was a design for a new urban precinct on Villiers Island, including a partial area to the north of it. It includes the configuration of all proposed public infrastructure. The design proposed residential/non-residential building topology and vehicular and pedestrian streets within the site. The proposed building topology aimed to meet contemporary standards for "passive house" and environmental performance. This includes new vehicular and pedestrian streets designed to reflect the introduction of such current aspects of 'smart city' design as driverless cars as possible.

A Sustainable Community The idea of the stepped garden approach has significant potentials as an idea of a “vertical neighborhood.� It creates accessible public roof gardens to building residents. Furthermore, it provides spacious public/private green terraces, and the sizeable exposed roof areas can be used to produce solar energy, rainwater, and purify air quality using vegetation. Moreover, the corridors in front of each apartment unit are considered as a place for people to socialize, by creating small seating areas, with a view looking at the central courtyard. The sustainable dimension of stepped topology is unique, and it extends beyond the physical design intentions.

The semi-public courtyards are the primary nodes within the site to distinguish it from the rest of the public spaces; the courtyards reveal a human dimensional physical environment. Furthermore, the interior courtyards are not fully enclosed; it is open; it has a sense of ownership to the residence but yet not entirely private. The space underneath the lifted volume is spacious, a great gateway during bad rainy weather in winter or hot sun exposure in summer, surrounded by green areas and ground-level retails and coffee shops.

Just as cities can invite city life, there are many examples of how the renovation of a single space or even change in furniture and details can invite people to a new pattern of use/habits. At the riverfront, a public realm designed to include parks, plazas, ground shops, sidewalks, and social gathering points either indoor, semi-outdoor, or outdoor. Whether people are enticed to walk around and stay in this space is very much a question of working carefully with the human dimension elements. By that, it is issuing a tempting invitation. At the other end of this scale, It represents recreational, optional activities that people might like such as, walking down the promenade, standing up to get a good look at the city and sitting down to enjoy the view and weather.

The main design challenge for the terminal building was to achieve complexity out of simplicity, considering economic parameters. A simple parabolic band that separates Landside from Airside and takes the load of the flying ribs covering the two main halls and transfer it to the ground. This design idea created voluminous spaces on both sides of the processor. It eased the way for the passengers to navigate throughout the different terminal departments starting from the check-in counters to passport control up to the departure concession lounges.

The interior design of the passenger building is based on passengers' experience. The color contrast between the surroundings and the patterns on the floor patterns make the traveling experience much more comfortable. The volumetric fluctuation of the terminal height navigates the passengers and enjoy their time along the way by providing various points to eat, shop, and rest before they take their flight.

Project Brief: The (300) Bed Children Hospital was planned to be the largest pediatric hospital in the middle east, located in Taif, Saudi Arabia. The new project is proposed on a brownfield to the south of Taif city downtown. My Involvement: I was assigned as a project manager/project architect, responsible generally of the project schedule, budget, coordination, and meeting deadlines. From the early stage of the design, the entire planning/design team was very cautious about the massing of the building, orientation, natural light, building shape, envelope, material selection, and sustainable aspects in general. Special attention was given to the orientation of the inpatient tower and how much it will be affected by sun exposure. The project won the title of "The Hospital of the Future Award" at Building Healthcare Awards in Dubai in 2015. The award complimented on its sustainable features and its careful design towards children's care.

Environmental Strategies Solar Analysis Schematic analysis of solar radiation (one year) has been performed to investigate the performance of the building to compare different design treatments and propose an optimum solution to reduce energy consumption, create a healthy environment and implement innovative faรงade solutions.

Local Material To create a life-cycle design and reduce energy emission, we have considered local materials to be used in cladding, curbs, and public spaces. Water Cooling Water features, in urban areas, have a good effect on the micro-climate of surrounding with its cooling effect from the evaporative process. Thus, evaporative cooling is one of the most efficient ways of passive cooling for building and urban spaces. It might have a minimal impact on the building but is still considerable.

Double Skin Facade

Green Terraces

Double Skin Faรงade As a double-skin facade technology, its thermal and daylight performance is still under scientific scrutiny. The bulk of research on the performance of this facade configuration is carried out in moderate climates. However, little is understood about the performance of double skin facade configurations in extreme hot arid climates.

Solar Analysis

Green Roof The plants on green roofs can capture airborne pollutants and atmospheric deposition. They can also filter noxious gases. The temperature moderating effects of green roofs can reduce demand on power plants, and potentially decrease the amount of CO2 and other polluting contents released into the air.

Healthcare - Al-Taif Children Hospital

The design of the main hospital lobby reflects the primary intent of the design philosophical commitment to providing exceptional patientand family-centered care, especially towards children. The colorful patterns on the floor that works as wayfinding, the greenery, the ceilingmounted features, and the natural light, collaboratively made this spacious lobby the central design features for the children's hospital.

Children Play Room

The concept of the interior design, is to make the spaces feel more comfortable and domestic to children. The rooms are designed with colorful graphic representation enhanced with playful cartoon characters, which suits not only children but also appropriate to older children. During the design, we pushed the process to ensure that the main spaces where children stay the most in, such as inpatient rooms, are warm and home-like.

Healthcare - Al-Taif Children Hospital

Design Coordination In any typical healthcare project, it consists of at least 12 multi-disciplinary teams working simultaneously together and probably on a single central file and preferably on a BIM platform. Therefore, as a part of the project architect's duty, It was my responsibility to review and coordinate all the drawings as the design progresses to ensure they are aligned with the architectural drawings. A typical surgical department illustrated here to show the level of complexity that requires a high level of coordination between several consultants, especially in the latter stages of the project.

Level of Details/Information within the Architectural scope of work: Hospital design standards, such as FGI, outlines comprehensive guidelines for the design and construction of hospitals and outpatient facilities. It provides minimum requirements for all the project disciplines. Moreover, as the lead design architect and as a project architect, it was in my responsibility to verify that the design meets those minimum requirements for all scopes, which ranged from details such as bedhead unit sockets to large mechanical systems and equipment specified to the project.

EE MIXED-USE TOWER Project Credit/Year: Project Category: Objective: Location: Area: Involvement Type: Main Software Used:

School Work“Option Studio�, 2012 Office Tower Energy & Sustainability Jeddah, Saudi Arabia 75,740 sqm Individual Work - Research & Design Revit, Rhino, 3Dmax, Photoshop

The project is a case study that took place in Jeddah, Saudi Arabia. The research mainly discusses the energy demands in office spaces in Saudi Arabia. The research proposed an alternative building design solutions and renewable energy applications to reduce energy consumption by establishing a design concept of a mixed-use tower. The integration of renewable energy strategies in combination with the architectural design should provide a logical calculation of the sustainable application validity. The main renewable energy application was mainly collected from solar and wind energy.

Arial View from North West Elevation

The design proposed is a 60-storey mixed-use skyscraper. Using renewable energy resources, the goal was to create a sustainable building project that consumes 20% less of its energy requirements. Around 200 units of wind turbines have been applied to satisfy 4-5% of the total energy consumption of the tower. The amount of wind turbine units have been distributed within service floors as structural and mechanical floors. Moreover, solar panels have been integrated on the top surface of the shading devices on the faรงade (louvers). These louvers are placed to face the optimum angel to collect maximum solar irradiation year-round. Based on the calculation, the project is estimated to save 20% of energy (electric consumption) each year.

Design Features: Fluidity The client wanted a design idea that is not too rigidly formal or conflicts with cultural habits. The concept was to design spaces to be flexible to use for both rental and private residential purposes. Sustainability Aspect of natural light and ventilation was carefully considered. In the same time aspect of solar heat gain and heat loss also studied. For example in Villa A, a large high ceiling skylight implemented at the center of the villa to allow daylight during the day, but on the other hand, narrower windows are specifically design at the south elevation to avoid overheated spaces. Connectivity The design is fluid and arranged to be connected visually by using horizontally and vertically arrangements, using glass partition, or open interlocking between functional zones. Smart Home The project implemented semi-automated controls, which can control many basic devices like, air-conditioning system, light, light colors, fresh air, drapes, intercom, garage doors, and audio systems.

RE-DIRECTING DAYLIGHT FACADE SYSTEM Project Credit/Year: Instructor: Project Category: Objective: Location: Area: Involvement Type: Main Software Used:

School Project (Thesis), 2019 Brady Peters Experimental/Academic Parametric Design Toronto, Canada N/A Individual Work Rhino, Illustrator, Arduino IDE (C++)

Daylight is the primary source of light that maintains the circadian system in the human body. Exposure to daylight has a positive impact on human health and well-being. Beyond functional performance, daylight is a fundamental aesthetic design element for architects. Traditional daylighting methods and metrics are designed for offices and therefore have shortcomings when it comes to the complexities of human activities in a residential setting. This research reports on a series of experiments that looked at how daylight can be shaded and redirected within multi-unit residential buildings (MURBS). The experiments addressed both the functional requirements of circadian light and working light levels, and the aesthetic dimensions of light and shadow. The experiments use a case study building in Toronto, Canada, and used computational daylight simulation, visualizations, and physical prototyping.

Perception of Light and Shadow

“Daylight strategies have limitations to control the available daylight and the presence and activities of building occupants.� Wyckmans, A. (2005). Intelligent Building Envelopes: Architectural Concept & Applications for Daylighting Quality.

Research - Redirecting Daylight Facade System

The initial idea of the re-directing daylight is to able to capture light and control it by using an adjustable reflector that re-directs the light into the desired direction based on personal reference depending on the time of the day.

Exploring Assembly Parts Prior Modeling and Testing

Active Multi-Axis Daylight Re-direction Façade System

Experimental Prototype Model

This test will follow a qualitative study strategy with a “Modelling–prototyping” demonstration. In the process, the study will propose assumptions of human activities by which the prototype should adapt accordingly to it. In the design process, several direct-reflective daylight re-direction systems were examined. Several studies on re-directing daylight systems showed potential benefits in terms of delivering light into the unlit spaces. However, instead of the previously limited use of the system, the author imagined exploiting this system to evolve as a dynamic façade configuration, which seems more promising. Therefore, each module consists of 2 sets of 17 layers of wood pieces (laser cut); each layer uniquely designed to consider any electrical and mechanical components to go in-between them if necessary, 5 servo motors, 1 stepper motor with a driver, one timing belt with timing pulley and 5 mirror panels. Each prototype is connected and controlled by Arduino micro controller using computational design software to develop a prototype to re-direct the daylight into space, responsive to specific sun position.

the design considered not only to work in 2 Axis (dual-axis) but to able to re-direct the light to any point in the space it is required to be able to adjust to any solar angel. The design is mainly two parts, the border frame, and the inner circle. In the inner circle, there are 5 mirrors in different sizes to fit in the circle, a servo-motor controls each mirror, and the inner circle itself is controlled by one stepper motor fixed into the external frame and moves the inner circle by a timing belt .

Research - Redirecting Daylight Facade System

The Experiments: In the following, the performance of the active Multi-Axis Daylight Re-direction Façade System was evaluated. Over hundreds of sequences of both video and photographs are recorded to observe the various spectrum of light that can be populated using the system. The physical simulation shows how the system can be adopted to occupants’ comfort preferences. Nevertheless, they also enhance the visual comfort and desire but also substantial potential to reduce the energy usage of the building.

Light Projection

Due to the unexpected weather conditions in Toronto, while running the test, I used a projected light casting directly on the modules to mimic the sunlight mechanism, the light was projected on an angle of 45 degrees from the ground and 2 meters away from the mock-up.
