Merits
The Geodesic Dome is a very robust structure because of the use of triangles in the design. It’s rigid and stable and transmits any stresses evenly by way of the structure. They’re extremely robust for his or her weight, and encloses the greatest quantity of house for the smallest surface area.
They will resist extremes of storm and wind, and have been tested in extreme climate condition around the world. Two cases are the Distance Early Warning Line Domes in Canada, and through 1975, a dome was constructed on the South Pole, the Amundsen-Scott South Pole Station (1975-2003), the place resistance to snow and wind loads may be very important. The Dome was 50 meters (164 ft) wide and 16 meters (fifty two ft) high, with 14×24 m (46×79 ft) steel archways, modular buildings, fuel bladders, and equipment. Indifferent buildings within the dome housed devices for monitoring the higher and decrease environment and for numerous and complicated projects.
The “Pillow Dome” was invented by James Tennant Baldwin, the American industrial designer. This clear, insulated structure of aluminium and Teflon is used in the Eden Project in Cornwall, England. This is a metal 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 enormous enclosed domes are linked together, and with a number of smaller domes, they provide habitats for plant species from around the world. The first dome has a tropical surroundings, and the second a Mediterranean environment. A computer-controlled environmental management system regulates the temperature and humidity in every dome
Drawbacks
Geodesic domes have many drawbacks, especially the place they are used to provide dwelling accommodation. The development has an amazing many intersecting surfaces, compared with standard structures, and all of these must be waterproof.
The surface covering is a problem because of the steady series of flat areas, every joined on a number of sides, and falling away to kind the surface of a big curve. Access for repair and upkeep is troublesome as nothing is flat, there is no ridge, and relying on the materials, may need even higher than normal care to avoid damage. The need to let light in and lack of suitable flexible supplies can also be a problem. Flexing of buildings resulting from normal atmospheric heating and cooling once more puts much more stress on the waterproof seals.
The curvature of the sides makes the inside area slightly more troublesome to use. The best roofing method is the tile or shingle. This runs into problems close to the top of the dome because the angle flattens – keeping water out here is difficult. One method is to arrange a single piece ‘cap’, or arrange a steeper pointed prime, 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 through 1968 he started building geodesic domes. He turned coordinator of the building of 17 domes at Pacific High School, and in the Santa Cruz mountains. Experimental geodesic domes have been 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 determined domes didn’t work well: He calls domes “smart but not wise.”
He lists problems –
The dome form makes numerous 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 can be 10 to 15 instances more expensive.
Labor prices are high for wiring.
The interior shape makes internal partitions more difficult to construct.
There can be problems with privacy, smells, sound nuisance, furniture fitting, and lack of headroom beside walls at upper levels.
