Rameshwari Jonnalagedda, a student at the Bartlett School of Architecture (UCL), explores the potential of nature-inspired design in modern air conditioning systems in her final project.
The TerraMound project draws inspiration from termite mounds and examines minimal surface geometries to develop energy-efficient cooling solutions. These shapes, known for their high surface-to-volume ratio, are ideal for optimizing heat exchange. The research involves creating a 3D-printed ceramic structure that mimics the porous architecture of termite mounds.

This structure features a built-in fan that draws air upwards, while water trickling from a pot at the top facilitates evaporation and cooling. The natural moisture-absorbing properties of clay enhance this process.
Using a 3D printer, this young scientist creates various minimal surface geometries with different porosities to further explore their cooling potential. Material composition experiments achieved a gradient effect by mixing terracotta clay with stone-white clay, demonstrating the possibilities of material variations in 3D printing.
Rameshwari Jonnalagedda envisions that cooling towers, much like these small models, could be created. These towers, with adjustable porosity levels, can be adapted to different environments—acting as moisture buffers in humid areas and as ventilation boosters in dry regions.
Integrating these eco-friendly cooling towers into buildings could utilize natural elements such as water circulation and airflow for efficient ecological temperature regulation.
Besides cooling, the adaptability of minimal surfaces allows for customized porosity and material composition, opening up various applications. These include facade panels, large 3D-printed walls, and structures like artificial reefs and urban gardens.
This research by a Bartlett School of Architecture student marks the beginning of a journey towards further exploration of geometric concepts, materials, and technologies in large-scale 3D printed projects. The goal is to create a future where sustainable, bio-inspired designs become the standard in construction and environmental integration.
