March 2nd - Presentation

Today was the Midterm presentation. I got some good and various comments and feedback from instructors in order to progress my design.
In the next step, I am going to go further in order to achieve next step goals as I mentioned today.

Here is the ink to my presentation:

First GC Snapshots!

For the first step, I simplified my spongy facade to some deformable cylinder-like shapes – which are supposed to act like pores of my sponge. However the aim of the design is to have a chaotic BSpline curves as pores. As general idea they are holes reacting to different levels of RH and the aim of their reaction is absorbing the condensate water.

GC ............................................. Computerization

As I mentioned before I want to design a porous polyhedral lattice inspired by sponge structure in order to absorb condensation water made on the facade. I am going to design a 3d-facade with various size openings (pores) extruded and scaled through the facade in order to have a chaotic porous lattice, hence for modeling I want to use GC.
For the first step, I want to sketch a simple plane included modular circle pores with adjustable radius to react to the indoor RH amount. For this aim RH range was assumed as a control point in modeling to control the pores size in order to increase contact surface with indoor air, so more absorption becomes possible.
On the other hand, in this case daylight control can be the second application of this design by a control system in the facade which can make a decision to adjust the system with RH or daylight in critical conditions.

Basic structure.........................Form and function

Cell types:

A sponge's body is hollow and is held in shape by the mesohyl, a jelly-like substance made mainly of collagen and reinforced by a dense network of fibers also made of collagen. The inner surface is covered with choanocytes, cells with cylindrical or conical collars surrounding one flagellum per choanocyte. The wave-like motion of the whip-like flagella drives water through the sponge's body. All sponges have ostia, channels leading to the interior through the mesohyl, and in most sponges these are controlled by tube-like porocytes that form closable inlet valves. Pinacocytes, plate-like cells, form a single-layered skin over all other parts of the mesohyl that are not covered by choanocytes, and the external pinacocytes also digest food particles that are too large to enter the ostia, while those at the base of the animal are responsible for anchoring it.

Porifera body structures

Water-current system:

Most sponges work rather like chimneys: they take in water at the bottom and eject it from the osculum ("little mouth") at the top. Since ambient currents are faster at the top, the suction effect that they produce does some of the work for free.
Sponges can control the water flow by various combination of wholly or partially closing the osculum and ostia (the intake pores) and varying the beat of the flagella, and may shut it down if there is a lot of sand or silt in the water.
Although the layers of pinacocytes and choanocytes resemble the epithelia of more complex animals, they are not bound tightly by cell-to-cell connections or a basal lamina (thin fibrous sheet underneath). The flexibility of these layers and re-modeling of the mesohyl by lophocytes allow the animals to adjust their shapes throughout their lives to take maximum advantage of local water currents.
Asconoid
The simplest body structure in sponges is a tube or vase shape known as "asconoid", but this severely limits the size of the animal. If it is simply scaled up, the ratio of its volume to surface area increases, because surface increases as the square of length or width while volume increases proportionally to the cube.
Syconoid
Some sponges overcome this limitation by adopting the "syconoid" structure, in which the body wall is pleated. The inner pockets of the pleats are lined with choanocytes, which connect to the outer pockets of the pleats by ostia. This increase in the number of choanocytes and hence in pumping capacity enables syconoid sponges to grow up to up to a few centimeters in diameter.
Leuconid
The "leuconid" pattern boosts pumping capacity further by filling the interior almost completely with mesohyl that contains a network of chambers lined with choanocytes and connected to each other and to the water intakes and outlet by tubes. Leuconid sponges grow to over 1 metre in diameter, and the fact that growth in any direction increases the number of choanocyte chambers enables them to take a wider range of forms, for example "encrusting" sponges whose shapes follow those of the surfaces to which they attach.

Sponges

Overview:

Sponges (poriferans) are very simple animals that live permanently attached to a location in the water - they are sessile as adults. There are from 5,000 to 10,000 known species of sponges. Most sponges live in salt water - only about 150 species live in fresh water. Sponges evolved over 500 million years ago.
The body of this primitive animal has thousands of pores which let water flow through it continually. Sponges obtain nourishment and oxygen from this flowing water. The flowing water also carries out waste products.

Anatomy:

The body of a sponge has two outer layers separated by an acellular (having no cells) gel layer called the mesohyl (also called the mesenchyme). In the gel layer are either spicules (supportive
needles made of calcium carbonate) or spongin fibers (a flexible skeletal material made from protein). Sponges have neither tissues nor organs. Different sponges form different shapes, including tubes, fans, cups, cones, blobs, barrels, and crusts. These invertebrates range in size from a few millimeters to 2 meters tall.

General features:

Classification:
Kingdom: Animalia (animals)
Phylum: Porifera (sponges)
Classes: Calcarea (calcerous sponges -having spicules), Demospongiae (horn sponges, like the bath sponge), Scleropongiae (coralline or tropical reef sponges), and Hexactinellida (glass sponges).

Sponge facade-original idea

SPONGES rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes, and the shapes of their bodies are adapted to maximize the efficiency of the water flow.

SPONGE is a gravity fed system, absorbed condensation-water from indoor air moves down the facade of the building via a series of ‘pores‘.

Second application: In background it is possible to make it safe for human consumption, the filtered water is collected and stored in an internal reservoir for disinfection.
