variable inputs in GC

For Ventilation rv = (A/n*π*v*k*Tr)


For Condensation r = A/2π*N*w

Den01(condensation)=1 Den02(ventilation)=4

Volume air needed=7350cm³


Den01(condensation)=4 Den02(ventilation)=4

Volume air needed=70680cm³

Den01(condensation)=9 Den02(ventilation)=7

Volume air needed=74640cm³


Den01(condensation)=16 Den02(ventilation)=7

Volume air=75210cm³


There are four different steps for number of holes(condensation and ventilation)as well as one hole for visual permeability(the big one) which its place is adapted to the location of the other holes.

Quantifying!!!


Regarding the presentation I mentioned three main stimulants and variations making the faced to react as followed:
• Temperature
• Relative humidity
• Ventilation
After presentation I did a lot of research on these topics in order to combine and restrain their various effects on the facade.

Thus, the first step is choosing a test volume for making calculations on document data that I gathered so I chose a simple cubic pavilion (3*3*3) for this issue.
In the next step, I found optimum indoor climate conditions and try to embed them in the design in order to find and adjust the number, size, step and time reactions of the pores.

For the first test, I assume my reaction time as 60 min, pores’ radius as 15, 30, 60cm with various functions and got some results. Then I found that not only I can reduce my reaction time to 10 min but also keep the pores’ size. Afterward, I am working on my GC model to improve it.

Material....C-change....Interactive tubes

C-CHANGE
Functions:
Open in response to heat or increased activity:
At high temperatures, the structure of the c_change™ membrane opens as the moisture levels rise. Excess heat can escape to the outside air.


Closed in response to cold or reduced activity:
Due to the lower level of moisture development in cold weather, the structure of the membrane closes, retaining the heat.


COLD / LOW MOISTURE
In Nature:
1 Fir cone is closed
In the Membrane:
2 Polymer structure condenses, thus providing better insulation.
3 High level of heat retention and moisture vapor permeability combine to create a pleasant climate.
4 Durable wind and water proof.


WARM / HIGH MOISTURE
In Nature:
1 Fir cone opens up
In the Membrane:
2 Polymer structure opens up and becomes extremely moisture vapor permeable.
3 Excess heat and moisture can escape to the outside air.
4 Durable wind and water proof.


c-change results:

  • c_change™membrane, in contrast to a hydrophobic membrane system, allows 25% more moisture to escape from the inside to the outside within the same period.
  • Alteration of the breathability at different temperatures and in different moisture situations
  • Moisture management – quantity in relation to time

c-change test results:

Water column: 20,000 mm
MVTR value: 18,000 g/m²/24h
