Merits
The Geodesic Dome is a really robust construction as a result of the usage of triangles in the design. It is inflexible and stable and transmits any stresses evenly by way of the structure. They are extraordinarily robust for their weight, and encloses the greatest volume of area 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 is 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 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 on the edges and form a thermal blanket, which insulate the buildings. Two huge enclosed domes are linked collectively, 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-controlled environmental management system regulates the temperature and humidity in every dome
Drawbacks
Geodesic domes have many drawbacks, particularly the place they’re used to provide living accommodation. The construction has a terrific many intersecting surfaces, compared with standard constructions, and all of those have to be waterproof.
The surface covering is a problem due to the steady series of flat areas, every joined on a number of sides, and falling away to form the surface of a big curve. Access for repair and upkeep is tough as nothing is flat, there is no ridge, and depending on the supplies, may need even higher than regular care to avoid damage. The necessity to let light in and lack of suitable versatile supplies is also a problem. Flexing of constructions as a result of normal atmospheric heating and cooling once more places much more stress on the waterproof seals.
The curvature of the sides makes the inside space slightly more difficult to use. The most effective roofing technique is the tile or shingle. This runs into problems near the top of the dome because the angle flattens – keeping water out here is difficult. One methodology 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 had 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 decided domes did not work well: He calls domes “smart however not wise.”
He lists problems –
The dome form makes various items troublesome to accommodate – chimneys, soil vents, fire escapes.
The conference rectangular shape of supplies leads to major wastage when reducing the triangular sections often used.
Windows may be 10 to 15 occasions more expensive.
Labor costs are high for wiring.
The interior form makes inside partitions more tough to construct.
There will be problems with privateness, smells, sound nuisance, furniture fitting, and lack of headroom beside partitions at higher levels.
