EASTGATE BUILDING OFFICE TOWERS HARARE
AT BEHAVIOR LEVEL
- inspired by the work of a tiny insect, the termite.
- The termite is one of nature's more accomplished builders, erecting the tallest structures on our planet (when measured against the size of the builder), and maintaining a constant temperature inside despite wide temperature swings outside.
- 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 complex is actually two buildings that shelter an interior atrium (right). Heat gain is reduced by limited glazing, deep overhangs, and building mass, and the architect took advantage of night cooling, thermal storage and convective air currents to moderate temperatures.
- During the day the heavy building mass and rock storage in the basement absorb the heat of the environment and human activity. At night, cool air is allowed into the bottom of the building and starts the convective flow that vents the hot daytime air through roof vents. This cool air is also stored and then distributed the next day into offices via hollow floors and baseboard vents.
