Biomimicry: HVAC Inspired by Termites
Add this biomimetic project to the board! Architect, Mick Pierce and engineers at Arup Associates successfully took inspiration from nature when designing the heating and cooling system of the Eastgate Centre in Harare, Zimbabwe, the country’s largest office and shopping complex. Where did they get this inspiration? African Termites!
If you’ve ever seen a termite mound you should still be impressed by these built by African termites in Zimbabwe. The termites build mounds reaching multiple feet in order to farm a fungus that feeds them. The finicky fungus must live at exactly 87 degrees F. While temperatures outside the mound walls vary by about 70 degrees F, they had a problem to solve. “The termites achieve this remarkable feat by constantly opening and closing a series of heating and cooling vents throughout the mound over the course of the day. With a system of carefully adjusted convection currents, air is sucked in at the lower part of the mound, down into enclosures with muddy walls, and up through a channel to the peak of the termite mound. The industrious termites constantly dig new vents and plug up old ones in order to regulate the temperature,” describes Abigail of Inhabitat.
