In 1991, the multinational Old Mutual investment group approached the Zimbabwean architect Mick Pearce with an audacious assignment. The group wished to construct a retail and office complex called the Eastgate Centre in Zimbabwe’s capital city of Harare that, at 55,000 square meters, would be the country’s largest commercial building. What Old Mutual didn’t wish to do was pay the high cost of air-conditioning such a massive space. Could Pearce, working with the Arup construction firm, devise a design that relied solely on passive, natural climate control?
