Biomimicry and Sustainable Design Concepts

In 1991, architect Mick Pearce faced the challenge of designing a large building in Harare, Zimbabwe, without using expensive air conditioning. Inspired by termite mounds, which naturally regulate temperature, Pearce employed biomimicry to create the Eastgate Centre. The building uses concrete and brick with high thermal mass to maintain comfortable temperatures, reducing energy use by up to 35%. Since its opening in 1996, the Eastgate Centre has become a landmark for sustainable architecture, prompting reflection on other potential nature-inspired innovations.
