Pneumatic System Model

Pneumatic System Model.jpg

In this model, which is prepared within the scope of Knowledge-Based Architectural Design course, it is aimed to transfer the information to the digital environment by using environmental data and to show the influence of this information on the designed pneumatic model. 

In today's architectural practice, environmental awareness and conscious designs are required. As a result of this, smart models should be produced considering the use of recyclable materials in building designs, the impact it has around the building and the internal performance criteria of the building. ETFE material, which has been used frequently in recent years, also contributes to building performance; It reduces building costs, increases the comfort of the activity inside and creates new forms with interesting behaviour. One of the models of ETFE manufacturers is cell-printed models and with this product, the pneumatic system takes shape according to the angle of incidence of solar rays. The panels in the direction in which the sun's rays are coming out extinguish, cell pressures on them approach each other and prevent the arrival of light. This prevents direct light absorption into the building. In the study, the working principles of this product have been taken and a model has been produced from alternative materials. It is aimed to represent this model in the digital and physical environment according to the direction and amount of light arrival, and also to produce information flow models in these environments.


Two approaches have been followed in the design of information generating models: Firstly, the data types obtained from the physical environment (amount of light, direction, angle of arrival of the sun's rays over time, etc.) were transferred with different applications in a computer environment. In the first of these applications, using a program that stores the weather information of the city we are in, the directions of light and the amount of energy it carries are shown and the pneumatic system is moved. In the second system, the data in the physical environment (amount of light) was obtained directly with the help of LDR sensor and transferred to the computer environment with Firefly application. In the second approach, without affecting the data in the physical environment, it directly affects the model that produces the response in the same environment. This is achieved by loading the predetermined behaviour model into the system through the Arduino program.
