Merits
The Geodesic Dome is a very robust construction because of using triangles within the design. It is inflexible and stable and transmits any stresses evenly through the structure. They’re extremely strong for their weight, and encloses the greatest quantity of space for the smallest surface area.
They can resist extremes of storm and wind, and have been tested in excessive weather condition around 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. Indifferent buildings within the dome housed instruments for monitoring the upper and decrease ambiance and for quite a few and sophisticated projects.
The “Pillow Dome” was invented by James Tennant Baldwin, the American industrial designer. This clear, insulated structure 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 kind a thermal blanket, which insulate the buildings. Two enormous enclosed domes are linked together, and with several 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 computer-controlled environmental control system regulates the temperature and humidity in each dome
Drawbacks
Geodesic domes have many drawbacks, particularly the place they’re used to provide dwelling accommodation. The construction has a fantastic many intersecting surfaces, compared with typical constructions, and all of those must be waterproof.
The surface covering is a problem as a result of continuous series of flat areas, each joined on several sides, and falling away to kind the surface of a large curve. Access for repair and upkeep is difficult as nothing is flat, there is no such thing as a ridge, and relying on the supplies, may need even better than regular care to avoid damage. The need to let light in and lack of suitable flexible supplies can be a problem. Flexing of buildings as a result of regular atmospheric heating and cooling once more puts a lot more stress on the waterproof seals.
The curvature of the sides makes the inside house 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 became 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 shape makes various items tough to accommodate – chimneys, soil vents, fire escapes.
The conference rectangular form of supplies leads to major wastage when slicing the triangular sections normally used.
Windows might be 10 to 15 instances more expensive.
Labor prices are high for wiring.
The interior form makes inside partitions more difficult to construct.
There could be problems with privacy, smells, sound nuisance, furniture fitting, and lack of headroom beside partitions at upper levels.
