Geodesic Dome Greenhouse: Merits and Drawbacks
Merits
The Geodesic Dome is a very sturdy construction resulting from the use of triangles in the design. It's inflexible and stable and transmits any stresses evenly via the structure. They're extremely robust for his or her weight, and encloses the greatest volume of space for the smallest surface area.
They can 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 during 1975, a dome was constructed on the South Pole, the Amundsen-Scott South Pole Station (1975-2003), where resistance to snow and wind loads is very important. The Dome was 50 meters (164 ft) wide and 16 meters (fifty two ft) high, with 14×24 m (46x79 ft) steel archways, modular buildings, fuel bladders, and equipment. Indifferent buildings within the dome housed devices for monitoring the upper and lower atmosphere and for quite a few and complex projects.
The "Pillow Dome" was invented by James Tennant Baldwin, the American industrial designer. This clear, 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 on the edges and form a thermal blanket, which insulate the buildings. Two big 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 control system regulates the temperature and humidity in each dome
Drawbacks
Geodesic domes have many drawbacks, particularly the place they're used to provide dwelling accommodation. The development has a great many intersecting surfaces, compared with conventional structures, and all of these have to be waterproof.
The surface covering is a problem due to the steady series of flat areas, every joined on several sides, and falling away to form the surface of a large curve. Access for repair and upkeep is difficult as nothing is flat, there is no such thing as a ridge, and depending on the supplies, might have even larger than regular care to keep away from damage. The necessity to let light in and lack of suitable versatile materials is also a problem. Flexing of constructions resulting from normal atmospheric heating and cooling again places a lot more stress on the waterproof seals.
The curvature of the sides makes the inside area slightly more tough to use. The most effective roofing methodology is the tile or shingle. This runs into problems close to the top of the dome because 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 turned coordinator of the building of 17 domes at Pacific High School, and within the Santa Cruz mountains. Experimental geodesic domes had 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 varied items troublesome to accommodate - chimneys, soil vents, fire escapes.
The conference rectangular shape of materials leads to major wastage when cutting the triangular sections normally used.
Windows might be 10 to fifteen occasions more expensive.
Labor prices are high for wiring.
The interior form makes internal partitions more troublesome to construct.
There may be problems with privateness, smells, sound nuisance, furniture fitting, and lack of headroom beside walls at upper levels.
