Nada EL-Gamal Architecture Student
My name is Nada EL-Gamal. It is my fourth year in Architecture school. Designing an environmentally friendly building has always been my dream since I joined the school of Architecture. It is very challenging to interpret a design that would serve the community and is context driven. I personally believe the it requires layers of research to know exactly the path that you as an Architect will follow because not every building that was designed really serves the purpose. It requires understanding the surroundings, the needs of the people and the structural material with its capabilities
to develop a concept that will lead to a successful design. I am also delighted to get a lot of learning outcomes out of parametric modelling course that would broadens my views

My main concept is derieved from the idea of metamorphosis of the snail (the life cycle) where there are transitions between stages

The shelter is made of a tensile structure waterproof strong fabric to accomidate mobility. Moreover it is designed to host more than one family. The concept of metamorphosis is reflected in the overlapping growing planes that have openings made of glass.

Modelling Process
The modelling iterations first started by creating a pivotal point where all planes would come out of however these were just conceptual attempts and the pivot had to change to a zone so late a sense of a spine was created that. Themodel was made to rotate around a curved surface inorder to create the curvilinear form and to show more enclosure. Furthermore the flyining planes were elimineted due to their height as they would not benefit the commercial area.

Fabrication
Laser cutting is the most efficient way to fabricate the curvilinear model form. 3D printing would not be economic besides that it would not help in constructing the raised planes of the model as it needs to be supported

DIE CASTING
CENTRIFUGAL CASTING
Die casting is a method of molding materials under high pressure and usually involves non-ferrous metals and alloys, such as zinc, tin, copper, and aluminum. The reusable mold is coated with a lubricant to help regulate the die’s temperature and to assist with component ejection. Molten metal is then injected into the die under high pressure, which remains continuous until the workpiece solidifies. This pressurized insertion is rapid, preventing any segment of the material from hardening before being cast. After the process is completed, the component is taken out of the die and any scrap material is removed.
Centrifugal casting is used to produce long, cylindrical parts such as cast iron pipe by relying on the g-forces developed in a spinning mold. Molten metal introduced into the mold is flung against the interior surface of the mold, producing a casting that can be free of voids. Originally invented as the de Lavaud process using water-cooled molds, the method is applied to symmetrical parts such as soil pipe and large gun barrels and has the advantage of producing parts using a minimal number of risers. For asymmetric parts that cannot be spun around their own axes, a variant of centrifugal casting, called pressure casting, arranges several parts around a common sprue and spins the molds around this axis. A similar idea is applied to the casting of very large gear rings, etc. Depending on the material being cast, metal or sand molds may be used.
PERMANAT MOLD
Permanent mold casting shares similarities with die casting and centrifugal casting, notably the use of reusable molds. These can be made of steel, graphite, etc. and are generally used to cast materials such as lead, zinc, aluminum and magnesium alloys, certain bronzes, and cast iron. It is a low-pressure process with pouring usually done by hand using multiple molds on a turntable. As the molds rotate through the various stations they are successively coated, closed, filled, opened, and emptied. One such method is known as slush casting, where the mold is filled but emptied before the metal fully hardens. Molten metal is dumped from the casting to produce a hollow, cast shell. A similar idea is used in the molding of hollow chocolate products such as Easter bunnies. The use of metal molds induces faster heat transfer through the mold, allowing the shell to harden while the core remains liquid.
Attempt 1
Preparing the materials and assembling the formwork and covering with foil for protection and giving texture.then making then casting the mold in it and leaving it for sometime to give the shape of 2D dripping and several grooves
Attempt 2
The second attempt I wanted to create something more 3D so I make a formwork of sticks covered it with cloth and casted the mixture several times as it was affected by gravity and needed. starting to remove the cast from the formwork giving me a stalaclitte like shape.

Extractions and Initial Thoughts
At first , i started modeling a similar shape to my material exploration on rhino however I found out that it would be better to start extracting inspirations and parameters from it in order to proceed to a parametric face lift that is more suitable and realistic. Thus, mainly the idea of dripping was taken from previous work besides grooving and and I started thinking of playing with louvers in a way to give this dripping effect(by letting them move in the xy and z plane according to certain attractors.

Grasshopper Second Iteration 8
The second facade iteration was adjusted is to try to vary the datum of the datum of louvers in order to make the facade more dynamic and to satisfy the different functions and the environmental attractors.
In the section the primary floors are for clients thus they are not protruded and of direct connection with the skin to create interaction, however later the hierarchy and space functions change through the 3rd , fourth and fifth floors becoming more for coworking spaces, offices

The plans through the bulding shows howthe extrusion vary on different levels and in section the hierarchy of spaces changes as you go up according to the function

Final Definition
The final definition is divided into 6 groups. first creating the facade surface on grasshopper according to functional attractor points. Secondly ,make the sun as an attractor point. the divinding the surface into lines that each has start middle and end inorder to be able to control the extrusion and the dripping. then merrging all and extruding the louvers.
