Merits
The Geodesic Dome is a really sturdy construction due to using triangles within the design. It is rigid and stable and transmits any stresses evenly by way of the structure. They are extremely robust for their weight, and encloses the greatest quantity of house for the smallest surface area.
They’ll resist extremes of storm and wind, and have been tested in excessive climate condition across 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 could be very important. The Dome was 50 meters (164 ft) wide and sixteen meters (52 ft) high, with 14×24 m (46×79 ft) metal archways, modular buildings, fuel bladders, and equipment. Indifferent buildings within the dome housed devices for monitoring the upper 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 within 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 on the edges and type a thermal blanket, which insulate the buildings. Two huge enclosed domes are linked collectively, and with several smaller domes, they provide habitats for plant species from across the world. The first dome has a tropical setting, and the second a Mediterranean environment. A computer-controlled 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 construction has an ideal many intersecting surfaces, compared with typical constructions, and all of those have to be waterproof.
The surface covering is a problem because of the steady series of flat areas, each joined on several sides, and falling away to form the surface of a large curve. Access for repair and maintenance is troublesome as nothing is flat, there isn’t a ridge, and depending on the supplies, may need even higher than normal care to keep away from damage. The need to let light in and lack of suitable flexible materials is also a problem. Flexing of structures as a consequence of regular atmospheric heating and cooling once more places a lot more stress on the waterproof seals.
The curvature of the sides makes the inside house slightly more difficult to use. The best roofing method is the tile or shingle. This runs into problems close to the highest of the dome because the angle flattens – keeping water out right here is difficult. One method 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 through 1968 he started building geodesic domes. He became 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 didn’t 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 often used.
Windows can be 10 to 15 instances more expensive.
Labor costs are high for wiring.
The interior form makes inner partitions more troublesome to construct.
There can be problems with privateness, smells, sound nuisance, furniture fitting, and lack of headroom beside walls at upper levels.
