Merits
The Geodesic Dome is a really sturdy construction due to the use of triangles within the design. It is inflexible and stable and transmits any stresses evenly by way of the structure. They are extraordinarily sturdy for their weight, and encloses the greatest volume of house for the smallest surface area.
They will resist extremes of storm and wind, and have been tested in excessive climate condition around 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 (fifty two 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 decrease ambiance and for numerous and sophisticated 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 form a thermal blanket, which insulate the buildings. Two large enclosed domes are linked collectively, and with a number of smaller domes, they provide habitats for plant species from around the world. The first dome has a tropical atmosphere, and the second a Mediterranean environment. A computer-controlled environmental management system regulates the temperature and humidity in each dome
Drawbacks
Geodesic domes have many drawbacks, especially where they’re used to provide dwelling accommodation. The development has a great many intersecting surfaces, compared with conventional constructions, and all of these should be waterproof.
The surface covering is a problem because of the continuous series of flat areas, each joined on several sides, and falling away to kind the surface of a giant curve. Access for repair and upkeep is difficult as nothing is flat, there isn’t a ridge, and depending on the supplies, may have even better than normal care to keep away from damage. The necessity to let light in and lack of suitable versatile supplies can also be a problem. Flexing of constructions as a result of normal atmospheric heating and cooling once more places a lot more stress on the waterproof seals.
The curvature of the sides makes the inside area slightly more troublesome to use. The best roofing technique 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 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 have been made from plywood, aluminium, sprayed foam, and vinyl. Children constructed their own domes and lived in them.
Having lived in a dome for a year, Kahn determined domes did not work well: He calls domes “smart but not wise.”
He lists problems –
The dome form makes varied items difficult to accommodate – chimneys, soil vents, fire escapes.
The conference rectangular form of materials leads to main wastage when cutting the triangular sections often used.
Windows could be 10 to 15 instances more expensive.
Labor prices are high for wiring.
The interior form makes internal walls more troublesome to construct.
There could be problems with privacy, smells, sound nuisance, furniture fitting, and lack of headroom beside partitions at upper levels.
