Merits
The Geodesic Dome is a very strong structure due to the usage of triangles in the design. It’s inflexible and stable and transmits any stresses evenly by means of the structure. They are extremely strong for their weight, and encloses the greatest volume of space for the smallest surface area.
They can resist extremes of storm and wind, and have been tested in excessive weather condition across the world. Two cases are the Distance Early Warning Line Domes in Canada, and during 1975, a dome was constructed at the South Pole, the Amundsen-Scott South Pole Station (1975-2003), where resistance to snow and wind loads is very important. The Dome was 50 meters (164 ft) wide and sixteen meters (fifty two ft) high, with 14×24 m (46×79 ft) metal archways, modular buildings, fuel bladders, and equipment. Detached buildings within the dome housed instruments for monitoring the upper and lower atmosphere and for quite a few and complex projects.
The “Pillow Dome” was invented by James Tennant Baldwin, the American industrial designer. This transparent, insulated construction of aluminium and Teflon is used within the Eden Project in Cornwall, England. This is a steel frame with an inflated skin of hexagonal cells stretched over it. The hexagons are sealed at the edges and type a thermal blanket, which insulate the buildings. Two large enclosed domes are linked together, and with several smaller domes, they provide habitats for plant species from across the world. The primary dome has a tropical surroundings, and the second a Mediterranean environment. A computer-managed environmental control system regulates the temperature and humidity in each dome
Drawbacks
Geodesic domes have many drawbacks, especially the place they’re used to provide residing accommodation. The development has an amazing many intersecting surfaces, compared with conventional buildings, and all of those should be waterproof.
The surface covering is a problem as a result of continuous series of flat areas, each joined on several sides, and falling away to type the surface of a giant curve. Access for repair and upkeep is tough as nothing is flat, there isn’t any ridge, and relying on the materials, may need even better than regular care to keep away from damage. The need to let light in and lack of suitable flexible supplies is also a problem. Flexing of constructions resulting from regular atmospheric heating and cooling once more places a lot more stress on the waterproof seals.
The curvature of the sides makes the inside area slightly more tough to use. The simplest roofing methodology is the tile or shingle. This runs into problems near the top of the dome as the angle flattens – keeping water out here is difficult. One technique is to arrange a single piece ‘cap’, or arrange a steeper pointed high, to cover this area. Some domes have been constructed of plastic sheets arranged to overlap and shed water.
Lloyd Kahn (pioneer of Green Building and Green Architecture) was influenced by Buckminster Fuller, and during 1968 he started building geodesic domes. He grew to become coordinator of the building of 17 domes at Pacific High School, and within the Santa Cruz mountains. Experimental geodesic domes were made from plywood, aluminium, sprayed foam, and vinyl. Children built their own domes and lived in them.
Having lived in a dome for a 12 months, Kahn decided domes did not work well: He calls domes “smart however not wise.”
He lists problems –
The dome form makes varied items tough to accommodate – chimneys, soil vents, fire escapes.
The convention rectangular form of supplies leads to main wastage when chopping the triangular sections normally used.
Windows will be 10 to fifteen instances more expensive.
Labor prices are high for wiring.
The interior form makes inside walls more difficult to construct.
There could be problems with privacy, smells, sound nuisance, furniture fitting, and lack of headroom beside walls at higher levels.
