The Eastgate Centre in Harare, Zimbabwe is a unique building that has been praised for its innovative design and sustainable features. Designed by architect Mick Pearce, the building is a prime example of how sustainable architecture can be both functional and beautiful.
Completed in 1996, the Eastgate Centre was designed to be a mixed-use development with shops, offices, and apartments. However, what sets the building apart is its use of passive cooling systems that allow it to maintain a comfortable temperature without the need for air conditioning.
The building's design is inspired by the traditional African masonry architecture found in the Great Zimbabwe ruins. The use of natural materials such as stone and brick helps to regulate the temperature inside the building. The walls are thick and have small air gaps that allow air to circulate, keeping the interior cool during the day and warm at night.
The Eastgate Centre also has a unique ventilation system that draws in fresh air from outside and circulates it through the building. The system uses fans to draw air into the building's atrium, which acts as a thermal chimney. As the hot air rises, it is vented out of the building, creating a constant flow of fresh air.
In addition to its passive cooling systems, the Eastgate Centre also has a number of other sustainable features. The building has a rainwater harvesting system that collects water from the roof and stores it in underground tanks. The water is then used for irrigation and flushing toilets.
The Eastgate Centre also has a solar panel system that provides electricity to the building. The system generates enough energy to power the building's lighting and other electrical needs.
Overall, the Eastgate Centre is a remarkable example of sustainable architecture. Its innovative design and use of passive cooling systems have earned it international recognition, and it has become a model for sustainable buildings around the world. As we continue to face the challenges of climate change, buildings like the Eastgate Centre will become increasingly important in creating a sustainable future.
