Merits
The Geodesic Dome is a very sturdy structure on account of the use of triangles in the design. It is rigid and stable and transmits any stresses evenly by means of the structure. They’re extremely robust for their weight, and encloses the greatest volume of space for the smallest surface area.
They will resist extremes of storm and wind, and have been tested in extreme climate condition around the world. Two cases are the Distance Early Warning Line Domes in Canada, and during 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 may 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) metal archways, modular buildings, fuel bladders, and equipment. Detached buildings within the dome housed devices for monitoring the higher and lower ambiance and for quite a few 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 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 at the edges and type a thermal blanket, which insulate the buildings. Two enormous 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 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 are used to provide residing accommodation. The construction has an ideal many intersecting surfaces, compared with typical constructions, and all of those should be waterproof.
The surface covering is a problem due to the continuous series of flat areas, each joined on a number of sides, and falling away to kind the surface of a big curve. Access for repair and upkeep is tough as nothing is flat, there isn’t any ridge, and relying on the supplies, might have even greater than normal care to avoid damage. The necessity to let light in and lack of suitable versatile materials can be a problem. Flexing of buildings due to 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 troublesome to use. The best roofing method is the tile or shingle. This runs into problems close to the highest 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 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 within the Santa Cruz mountains. Experimental geodesic domes were 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 however not wise.”
He lists problems –
The dome form makes various items troublesome to accommodate – chimneys, soil vents, fire escapes.
The convention rectangular shape of supplies leads to main wastage when reducing the triangular sections normally used.
Windows might be 10 to fifteen occasions more expensive.
Labor prices are high for wiring.
The interior shape makes inside partitions more troublesome to construct.
There might be problems with privateness, smells, sound nuisance, furniture fitting, and lack of headroom beside partitions at higher levels.
