Type: Scripting and GH tool development
Role: Linking data from sources, Coding and Facade development
This tool is designed to provide architects with sustainable designs strategies, which analyze the environmental data and automatically generate a comfortable and responsive facade.
This grasshopper tool is designed to generate a responsive ventilation system which first collects climate data from websites. Compares the global data from ladybug to data from real time sensors. It then evaluates if the facade should be open and closed. The tool also controls the geometry of the facade panels in 2D and 3D as well as number of sensors required through out the space. The system also controls the angle of rotation and the variable gradient with which it should open and close.
The tool contains sub-components as shown in the image on the left. Location of the place can be changed for windrose and climate data. Efforts were made to make this prototype workable in real time as well so we connected an arduino and used a wind sensor to produce real time data. We linked physical model with the digital in Rhino grasshopper which worked in sync together. Both would respond and open and close together as the data would feed into it.
Sensor Generator Function
1. Randomly changing number of sensors
2. Apply the sensors on any types of surfaces
3. Showing the physical geometries of sensors
4. Changing the radius of the sensor geometries
Generating 2D panels with different shapes
1. Open and close based on the wind speed
2. Randomly assign two lines for the responsive facade.
3. Changing the density of the Panels.
4. Changing the opening orientation of the panels Changing maximum and minimum turning angle of the facade.
Changing panel densities
Changing panel orientations
Arduino physical response facade model
When the wind speed is higher than 0.5 m/s. This responsive system will be started in sequence.
When the wind speed is higher than 0.5 m/s. This responsive system will be started at the same time.
Data was collected from EPW files and real time arduinos, compared and linked into Facade generator to operate.
