Geodesic Dome Greenhouse: Merits and Drawbacks

Merits

The Geodesic Dome is a very sturdy structure resulting from using triangles within the design. It’s inflexible and stable and transmits any stresses evenly through the structure. They’re extraordinarily sturdy for their weight, and encloses the greatest volume of space for the smallest surface area.

They’ll 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 at the South Pole, the Amundsen-Scott South Pole Station (1975-2003), where resistance to snow and wind loads may be very important. The Dome was 50 meters (164 ft) wide and sixteen meters (52 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 decrease ambiance and for numerous and complex projects.

The “Pillow Dome” was invented by James Tennant Baldwin, the American industrial designer. This transparent, insulated structure 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 type 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 around the world. The first dome has a tropical environment, and the second a Mediterranean environment. A computer-controlled environmental management system regulates the temperature and humidity in each dome

Drawbacks

Geodesic domes have many drawbacks, especially where they’re used to provide residing accommodation. The development has a terrific many intersecting surfaces, compared with standard constructions, and all of those should be waterproof.

The surface covering is a problem because of 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 troublesome as nothing is flat, there is no ridge, and depending on the materials, may have even larger than regular care to keep away from damage. The necessity to let light in and lack of suitable versatile supplies can be a problem. Flexing of constructions due to regular atmospheric heating and cooling once more puts a lot more stress on the waterproof seals.

The curvature of the sides makes the inside house slightly more tough to use. The simplest roofing methodology is the tile or shingle. This runs into problems close to the highest of the dome because the angle flattens – keeping water out right here is difficult. One method is to arrange a single piece ‘cap’, or arrange a steeper pointed top, 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 but not wise.”

He lists problems –

The dome shape makes numerous items troublesome to accommodate – chimneys, soil vents, fire escapes.

The conference rectangular form of supplies leads to main wastage when cutting the triangular sections normally used.

Windows might be 10 to 15 instances more expensive.

Labor costs are high for wiring.

The interior form makes inner walls more troublesome to construct.

There can be problems with privacy, smells, sound nuisance, furniture fitting, and lack of headroom beside walls at higher levels.
