Merits
The Geodesic Dome is a very robust construction as a consequence of the use of triangles within the design. It’s inflexible and stable and transmits any stresses evenly by the structure. They’re extraordinarily 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 through 1975, a dome was constructed at the South Pole, the Amundsen-Scott South Pole Station (1975-2003), where 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) metal archways, modular buildings, fuel bladders, and equipment. Detached buildings within the dome housed instruments for monitoring the higher and decrease ambiance and for numerous 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 in 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 kind 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 across the world. The first 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 are used to provide living accommodation. The construction has an ideal many intersecting surfaces, compared with standard structures, and all of those should be waterproof.
The surface covering is a problem due to the steady series of flat areas, each joined on several sides, and falling away to kind the surface of a large curve. Access for repair and maintenance is tough as nothing is flat, there is no such thing as a ridge, and depending on the supplies, might have even greater than regular care to keep away from damage. The necessity to let light in and lack of suitable versatile supplies can be a problem. Flexing of constructions because of normal atmospheric heating and cooling again puts much more stress on the waterproof seals.
The curvature of the sides makes the inside area slightly more difficult to use. The best roofing methodology is the tile or shingle. This runs into problems near the highest of the dome as the angle flattens – keeping water out right here is difficult. One technique 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 during 1968 he started building geodesic domes. He grew to become coordinator of the building of 17 domes at Pacific High School, and in 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 determined domes did not work well: He calls domes “smart but not wise.”
He lists problems –
The dome form makes numerous items troublesome to accommodate – chimneys, soil vents, fire escapes.
The convention rectangular form of materials leads to major wastage when slicing the triangular sections often used.
Windows can be 10 to fifteen occasions more expensive.
Labor prices are high for wiring.
The interior shape makes inside walls more troublesome to construct.
There might be problems with privacy, smells, sound nuisance, furniture fitting, and lack of headroom beside walls at higher levels.
