Our goal started by redesigning a past project that modified the original street house façade. We use C# in grasshopper to create a new transparent façade that could interact with the surrounding and create good interior condition for the user. We started analyzing the sun position, radiation, temperature and the average wind direction throughout the year.

We want to design a new grid system that is flexible and easy to adjust. Therefore, we decided to use fabric as the main material since it could block the sunlight and still have the flexibility for adjustment. The fabric skin is controlled by two layers of steel grid that also strengthen the façade system. The exterior is fixed to the concrete structure and the interior grid is controlled by the environmental conditions, and this is when the coding comes in handy. The transformation could be defined by three elements (scale, rotate and depth) that are adjusted based on the sun position, wind direction and temperature. Moreover, considering user experience, we decline the movement of eye-height units to avoid blocking the view from indoor spaces. Our goal is to find the right balance for various environmental circumstances.
