This ongoing research project focuses on the self-organizing material behavior of dune sand. It documents several in-depth explorations using a hybrid digital / analog machine process for creating sand-based patterns. These can be optimized based upon opening size and placement. Each individual sand cell is born from a unique opening that is used to drain sand. The process is specifically designed for work in desert environments where dune sand is abundant.
The research investigates how the self-organizing properties of dune sand can be used to create shading patterns that are computationally optimized to form weather-responsive architectural surfaces. The methodology integrates evolutionary computation with performative design, utilizing weather-based analytics to address sun exposure, UV radiation, heat, and wind. This approach enables material optimization, resulting in a series of design options that are highly responsive to the unique conditions of desert environments, with dune sand serving as the primary material.
The process begins with experiments on self-organizing sand sequences that work with specific point placements for patterning. These point locations are refined and carefully marked atop laser-cut planes, allowing the sand to pour and accumulate into specific configurations. The study examines variables such as the size and number of openings. The configurations are ultimately stabilized using a binder, and these stabilized patterns are used in various physical surface sequences.
The project ultimately optimizes the sand configurations by optimizing the most effective arrangements of openings that generate the self-organized piles; this optimization is tailored to specific desert locations.
This research contributes to the ongoing discourse on designing for extreme arid environments, offering insights into the integration of computational processes and material science. Moreover, it aligns with the United Nations' sustainability goals, particularly in the areas of sustainable communities, climate action, and responsible consumption and production.
