Merits
The Geodesic Dome is a very strong construction on account of the usage of triangles in the design. It is rigid and stable and transmits any stresses evenly via the structure. They’re extremely robust 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 extreme weather condition around the world. Two cases are the Distance Early Warning Line Domes in Canada, and during 1975, a dome was constructed at the South Pole, the Amundsen-Scott South Pole Station (1975-2003), the place resistance to snow and wind loads is 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 devices for monitoring the upper and decrease atmosphere and for numerous 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 in 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 form a thermal blanket, which insulate the buildings. Two huge enclosed domes are linked together, and with several smaller domes, they provide habitats for plant species from across the world. The primary dome has a tropical surroundings, 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 are used to provide residing accommodation. The construction has an ideal many intersecting surfaces, compared with conventional buildings, and all of these should be waterproof.
The surface covering is a problem because of the continuous series of flat areas, each joined on a number of sides, and falling away to kind the surface of a large curve. Access for repair and maintenance is difficult as nothing is flat, there is no ridge, and depending on the materials, may need even better than regular care to avoid damage. The necessity to let light in and lack of suitable flexible supplies can also be a problem. Flexing of structures due to regular atmospheric heating and cooling again 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 method is the tile or shingle. This runs into problems close to the top of the dome as the angle flattens — keeping water out right here is difficult. One method is to arrange a single piece ‘cap’, or arrange a steeper pointed prime, 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 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 yr, Kahn decided domes did not 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 shape of supplies leads to main wastage when slicing the triangular sections normally used.
Windows can be 10 to fifteen instances more expensive.
Labor costs are high for wiring.
The interior shape makes internal walls more troublesome to construct.
There will be problems with privacy, smells, sound nuisance, furniture fitting, and lack of headroom beside walls at higher levels.
