Merits
The Geodesic Dome is a very strong structure attributable to the usage of triangles within the design. It is inflexible and stable and transmits any stresses evenly through the structure. They’re extraordinarily robust for their weight, and encloses the greatest volume of house for the smallest surface area.
They’ll resist extremes of storm and wind, and have been tested in extreme weather condition around 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), the place resistance to snow and wind loads may be very important. The Dome was 50 meters (164 ft) wide and sixteen meters (52 ft) high, with 14×24 m (46×79 ft) steel archways, modular buildings, fuel bladders, and equipment. Indifferent buildings within the dome housed instruments for monitoring the higher and lower environment and for numerous and complicated projects.
The “Pillow Dome” was invented by James Tennant Baldwin, the American industrial designer. This clear, 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 on the edges and form a thermal blanket, which insulate the buildings. Two big enclosed domes are linked together, and with a number of smaller domes, they provide habitats for plant species from around the world. The primary dome has a tropical environment, and the second a Mediterranean environment. A pc-managed environmental control system regulates the temperature and humidity in every dome
Drawbacks
Geodesic domes have many drawbacks, particularly where they’re used to provide dwelling accommodation. The development has an ideal many intersecting surfaces, compared with standard structures, and all of these have to be waterproof.
The surface covering is a problem as a result of continuous series of flat areas, every joined on several sides, and falling away to type the surface of a large curve. Access for repair and upkeep is difficult as nothing is flat, there isn’t any ridge, and relying on the supplies, may need even greater than regular care to keep away from damage. The necessity to let light in and lack of suitable flexible materials can also be a problem. Flexing of structures as a consequence of normal atmospheric heating and cooling again places a lot more stress on the waterproof seals.
The curvature of the sides makes the inside space slightly more tough to use. The best roofing technique 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 method is to arrange a single piece ‘cap’, or arrange a steeper pointed top, 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 year, Kahn determined domes didn’t work well: He calls domes “smart however not wise.”
He lists problems –
The dome shape makes varied items difficult to accommodate – chimneys, soil vents, fire escapes.
The conference rectangular form of materials 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 inner walls more tough to construct.
There could be problems with privacy, smells, sound nuisance, furniture fitting, and lack of headroom beside partitions at upper levels.
