Merits
The Geodesic Dome is a very sturdy structure because of using triangles within the design. It is inflexible and stable and transmits any stresses evenly via the structure. They’re extremely sturdy for their weight, and encloses the greatest quantity 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 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 16 meters (52 ft) high, with 14×24 m (46×79 ft) steel archways, modular buildings, fuel bladders, and equipment. Detached buildings within the dome housed instruments for monitoring the higher and lower ambiance and for quite a few and complicated projects.
The “Pillow Dome” was invented by James Tennant Baldwin, the American industrial designer. This clear, 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 enormous enclosed domes are linked together, 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-managed environmental control system regulates the temperature and humidity in each dome
Drawbacks
Geodesic domes have many drawbacks, especially the place they’re used to provide residing accommodation. The development has a great many intersecting surfaces, compared with conventional buildings, and all of those must be waterproof.
The surface covering is a problem due to the continuous series of flat areas, every joined on a number of sides, and falling away to type the surface of a giant curve. Access for repair and upkeep is tough as nothing is flat, there is no ridge, and relying on the materials, might have even higher than regular care to avoid damage. The need to let light in and lack of suitable flexible supplies can also be a problem. Flexing of buildings attributable to normal atmospheric heating and cooling once more puts much more stress on the waterproof seals.
The curvature of the sides makes the inside area slightly more difficult to use. The simplest roofing technique is the tile or shingle. This runs into problems near the highest of the dome because the angle flattens – keeping water out 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 built their own domes and lived in them.
Having lived in a dome for a year, Kahn decided domes didn’t work well: He calls domes “smart however not wise.”
He lists problems –
The dome form makes various items difficult to accommodate – chimneys, soil vents, fire escapes.
The convention rectangular shape of supplies leads to major wastage when cutting the triangular sections usually used.
Windows may be 10 to 15 times more expensive.
Labor prices are high for wiring.
The interior shape makes internal partitions more tough to construct.
There might be problems with privacy, smells, sound nuisance, furniture fitting, and lack of headroom beside partitions at higher levels.
