Concluding Thoughts
Through the experiment, the initial hypothesis that the four-slant roof would create the largest volume of occupiable space at the lower portion of the testing environment was supported. The output that supports this is the graphic visualization displaying each of the final shots of each video test.
It should be noted that the volume of each testing environment did increase with each subsequent test as the geometry of each roof changed. It is possible that the specific geometry of the four-slant roof does not directly result in the largest volume of occupiable space within the testing environment. However, while the specific geometry may not have caused this result, increasing the number of slants in the geometry of the roof structure allows for a greater volume to be achieved. This is the important finding within this experiment.

Future Steps
Ultimately, a testing method to visualize the temperature differential of an enclosed space was developed throughout the course of the project. This method is clearly shown through the movement of ink within water, as the ink effectively shows how hot air moves throughout an enclosed space. While not the explicit goal, this visual testing method developed throughout this project can be used in numerous different applications. These applications can extend beyond an enclosed space and can branch into showing the intentional movement of hot air through cross ventilation, and even showing leakage of hot air from a seemingly enclosed structure. This testing method can essentially be utilized in any scenario in which both hot and cool air are present within a space.
One future improvement of this project regards the heat source. Currently a concrete block is heated in an oven until it reaches a specific temperature. Ensuring that the temperature of the block is the same between tests in an imperfect practice. Integrating a heat source into the base of the testing enclosure would help ensure a uniform temperature across each experiment. An additional improvement could include venting at the top of each roof geometry to simulate a testing environment which is more closely aligned with actual construction techniques of Indonesia.

Design Proposal
Humans spend nearly 90% of their time indoors. This is especially true when considering how quickly the globe is urbanizing, with more and more people subjecting themselves to urban living. Images of these dense cities are very prevalent, and none of them look too inviting. Typically, these images include smog and industrial plants – both of which are known to pollute the air and reduce outdoor air quality. As such, many get the idea that the indoor air quality is of a better quality. However, this may not be particularly true. Many interior finishes and household materials contain pollutants which can manifest over time and can be anywhere between 2-5 times more concentrated indoors. One remediation tactic which can be utilized is natural ventilation, which can assist in removing the harmful indoor pollutants and replace them with outside air. The outdoor air, while also polluted, needs to be filtered before entering into the interior space. This ultimately begs the question, how can apertures placed on the exterior of a space aid in expelling interior pollutants while filtering outdoor pollution to provide clean, safe air to the interior of a space.
Utilizing the water bath testing method from the aforementioned project, one may begin testing this question. One may begin by using two dyes, one to represent the interior air and another to represent the exterior air. For this example, lets assign a red dye to the interior air and a green dye to the exterior air. This experiment would start with the red dye being placed within the testing enclosure from the previous project, with an aperture located at each side of the testing enclosure. Green dye would be placed outside of the testing enclosure in the water-filled aquarium, and following the opening of the aperture, would be blown into the testing enclosure. This process is intended to simulate outside air being blown into an interior space. The main design innovation would occur within the aperture, in which one would attempt to design a filter that would filter out outdoor pollutants before they entered the interior space. Utilizing the water bath testing method from the previous project allows one to use an existing body to research to build upon previously learned knowledge, and venture into a new area of study.
