Biomimicry: Zimbabwe termite Introduction A typical example of biomimicry is the lesson from the termites on how to create sustainable buildings. Many people believe that termites are just a liability in terms of destroying structures but East gate Building, an office complex in Harare, Zimbabwe, in Africa has a different story.Termites in a Subterranean termites(Macrotermes)Termite exclusive to the Zimbabwe in AfricaTermites build earth structures that maintain the inner temperature because of a particular ventilation system.They are able to regulate temperatures of 30 degrees CThe termites are constantly tweaking these openings for optimum performance, sometimes adding wet mud that aids cooling with its evaporative effectsTermites have entirely passive structureThey make use of the so-called stack effect, convective airflow from cool to warm The termites are able to maintain a constant temperature inside despite wide temperature swings outside.Hydrophilic (water-loving) amp. hydrophobic (water-repelling) sidesTermites need contact with the soil to survive. They live in underground colonies or in wet areas aboveground. They build tunnels to reach food and every spring, groups of reproductive termites fly off to start new colonies.The mounds that they build are extremely durable structures of mud, often employing sophisticated buttressing and, in the case of so-called compass mounds, a precise shape and siting that optimize the effects of the sun.The fungus combs they cultivate are harvested locally, and transported to the base of the nest.Termite dens look otherworldly, but they are surprisingly comfortable places to live.The inner part of a termite den holds steady at a comfortable (to a termite) 87 degreesA typical example of this scenario is the lesson from the termites on how to create sustainable buildings. Many people believe that termites are just a liability in terms of destroying structures but East gate Building, an office complex in Harare, Zimbabwe, in Africa has a different story. The air conditioning systems in this gate are designed on self-cooling mounds of Macrotermes michaelseni. The termites maintain their inner nest temperature to within one degree, day and night as the temperatures outside moves from 42 °C to 3 °C (Downton, 407). Through this, there is considerable energy saving and this case presents a good example of bio mimicry and its application. This concept can be applied in many other such structures with the aim of harnessing the activities of the termites to release energy for use in architectural concepts (Florax, et al, 63).East gate Mound in Zimbambwe.Works citedDownton, Paul F.
