Deep eaves are a traditional solution in Africa, shading the walls completely from the high summer sun, while allowing the lower winter sun to warm the building in the morning. Further, passive cooling systems are particularly appropriate for this part of Africa because, long before humans thought of it, passive cooling was being used by the local termites. Termite mounds include flues which vent through the top and sides, and the mound itself is designed to catch the breeze. As the wind blows, hot air from the main chambers below ground is drawn out of the structure, helped by termites opening or blocking tunnels to control air flow.

Pearce's practice is in Harare, and he specialises in buildings which are low cost, low maintenance, and have low environmental impact.

In Pearce was awarded the Prince Claus Award for culture and development, for his work on Eastgate. Designing for thermal control The Eastgate Centre's design is a deliberate move away from the "big glass block". Passive cooling Passive cooling works by storing heat in the day and venting it at night as temperatures drop.

Heat is absorbed by the fabric of the building, which has a high heat capacity, so that the temperature inside increases but not greatly. The warm internal air is vented through chimneys, assisted by fans but also rising naturally because it is less dense, and drawing in denser cool air at the bottom of the building. Modern use of traditional solutions To work well, the building must be very carefully designed.
