Merits
The Geodesic Dome is a very robust structure due to the use of triangles within the design. It’s inflexible and stable and transmits any stresses evenly by way of the structure. They’re extremely sturdy for his or her weight, and encloses the greatest volume of area for the smallest surface area.
They’ll 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 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 environment and for quite a few and complicated 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 form a thermal blanket, which insulate the buildings. Two big 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 setting, and the second a Mediterranean environment. A computer-managed environmental control system regulates the temperature and humidity in every dome
Drawbacks
Geodesic domes have many drawbacks, especially where they are used to provide living accommodation. The development has an awesome many intersecting surfaces, compared with typical constructions, and all of these must 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 form the surface of a large curve. Access for repair and maintenance is tough as nothing is flat, there is no ridge, and depending on the materials, might have even larger than normal care to avoid damage. The necessity to let light in and lack of suitable versatile materials can also be a problem. Flexing of structures as a result of normal atmospheric heating and cooling once more puts a lot more stress on the waterproof seals.
The curvature of the sides makes the inside space slightly more tough 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 here is difficult. One methodology 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 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 yr, Kahn determined domes didn’t work well: He calls domes “smart however not wise.”
He lists problems –
The dome form makes numerous items difficult to accommodate – chimneys, soil vents, fire escapes.
The conference rectangular shape of materials leads to major wastage when cutting the triangular sections usually used.
Windows might be 10 to 15 occasions more expensive.
Labor prices are high for wiring.
The interior form makes inner walls more troublesome to construct.
There may be problems with privateness, smells, sound nuisance, furniture fitting, and lack of headroom beside partitions at higher levels.
