This fortress, built by termites, is a triumph of cooperative engineering, featuring sturdy walls to repel enemies, deep dungeons for moisture gathering, and internal space for food storage and crop cultivation. At the core of this complex lies the queen, a monumental figure who produces a thousand eggs daily to sustain the army of masons and gardeners. She resides in a special chamber, a voluntary prisoner whose bulk eventually prevents her from moving or squeezing through the corridors built by the attentive workers.

In the semi-arid environments of the southern African savanna, where the termite Macrotermes michaelseni thrives, the colonies face thermal fluctuations far more severe than their shaded Asian counterparts. These African mounds operate in an environment characterized by direct sun exposure and large daily temperature swings, sometimes reaching up to a 20°C difference between high and low points. Furthermore, this habitat experiences strong external winds, averaging up to 5 m s⁻¹.

For decades, studying the functional principles of termite mounds, particularly the precise flow of air and gas, was hampered by the mound’s opaque and complex structure. Traditional visualization methods, such as casting the tunnels with plaster or physically sectioning the mound, are inherently destructive, offering only partial and non-reusable information. Furthermore, the complexity of internal structures, featuring a network of tunnels, chimneys, and pores, makes direct in situ flow measurement difficult and localized.

Traditional large commercial buildings—often termed “big glass blocks”—rely heavily on expensive, energy-intensive air conditioning systems to maintain comfortable temperatures. These mechanical systems not only increase operating costs but also recycle air, leading to high levels of internal air pollution. Given the investment group’s reluctance to finance costly mechanical air conditioning, Pearce was tasked with a seemingly impossible challenge: designing a massive building that could cool itself naturally.

While architects have found success replicating macro-scale effects, like the chimney structure, a full, functional replication of the termite’s climate control system remains elusive. Decades of research have established key insights: the mound’s architecture, not just the insects’ presence, determines stability; thermal gradients drive convective flow; and the material composition buffers extremes.
