How does the Eastgate Centre work?
How does the Eastgate Centre work?
The Eastgate Centre, largely made of concrete, has a ventilation system which operates in a similar way. Outside air that is drawn in is either warmed or cooled by the building mass depending on which is hotter, the building concrete or the air. Air is continuously drawn from this open space by fans on the first floor.
What features of termite mounds were incorporated in the design of the Eastgate Centre in Zimbabwe?
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.
How do termite mounds stay cool?
How does the mound dissipate air through its network of holes? As the sun moves through the sky during the day, the air in the thinner chimneys on the outer edges of the mound heat up quickly, while the air in the mound’s big, central chimney stays relatively cool.
What insect inspired the building plans for the Eastgate Centre building?
What’s Eastgate Centre’s secret? Termites. In the 1990s, Mick Pearce, the building’s architect, took his inspiration from mounds built by fungus-farming termites he saw on a nature show. The insects created their own air conditioning systems that circulated hot and cool air between the mound and the outside.
Who designed Eastgate?
Eastgate Centre, Harare./Architects
The Eastgate Center designed by Mick Pearce uses passive and energy‑efficient mechanisms of climate control to cool residents.
How do termites build their mounds 20 feet tall?
The mound is constructed out of a mixture of soil, termite saliva and dung. Although the mound appears solid, the structure is incredibly porous. Its walls are filled with tiny holes that allow outside air to enter and permeate the entire structure.
What was the natural inspiration for the Eastgate Center in Zimbabwe?
While subsequent research on termite mounds has altered our understanding of the function of mound structures, the Eastgate Centre still achieves a controlled internal climate with the help of cost-effective and energy-efficient mechanisms originally inspired by termite mounds. used in the Eastgate building in Harare.
How long does it take termites to build a mound?
four to five years
Termite mounds can take four to five years to build, but a really heavy downpour might cause a third of the mounds to collapse. So termites are always scurrying to rebuild their mounds as fast as the weather erodes them.
Why do termites build mounds?
While they might look like apartment complexes, termite mounds actually function as a ventilation system for the colony that lives deep underground. That change in temperature will change the air flow and the termites will change their behavior. Termite mounds function as a ventilation system.
Where do termites nest?
The nests may be located between 4 to 18 inches or more underground and are made up of several rooms, called galleries. These galleries are connected by tunnels made of mud. The tunnels not only connect galleries, but also connect the termites to food sources.
Why do designers use biomimicry?
Looking to nature for inspiration can help individual designers in multiple ways. Designers are innately curious, and biomimicry provides the opportunity to learn about life’s water, energy and material-use strategies. This perspective broadens the design space to bring new solutions to the table.
Who is the architect of Eastgate Centre Harare?
The Eastgate Centre is a shopping centre and office block in central Harare, Zimbabwe whose architect is Mick Pearce. Designed to be ventilated and cooled by entirely natural means, it was probably the first building in the world to use natural cooling to this level of sophistication.
How is Eastgate Centre in Harare passive cooled?
Passively cooled, Eastgate uses only 10% of the energy needed by a similar conventionally cooled building. Eastgate is emulated by London’s Portcullis House (2001), opposite the Palace of Westminster. The distinctive giant chimneys on which the system relies are clearly visible.
Why was the Eastgate building built in Zimbabwe?
It is the architectural expression of the technology brought to Zimbabwe by the mineral hungry settlers in the late 19th century. Eastgate comprises two buildings side by side linked together by a glass roof.
How big is the Eastgate Centre in London?
It opened in 1996 on Robert Mugabe Avenue and Second Street, and provides 5,600 m² of retail space, 26,000 m² of office space and parking for 450 cars. The Eastgate Centre’s design is a deliberate move away from the “big glass block”.
