The Eastgate Centre in Harare, Zimbabwe, pictured outside and inside below, uses passive cooling (read more at Wikipedia) to keep cool without exhaustive power consumption. Designed by Zimbabwean architect Mick Pearce, the shopping and office complex opened in 1996. Pearce works in "sustainable architecture" and developed the field upon an interest in biomimicry. The passive cooling design of the Eastgate Centre is said to be based on principles observed in southern Africa's ubiquitous termite mounds.
