Geodesic Dome Greenhouse: Merits and Drawbacks


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

They’ll 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 through 1975, a dome was constructed on 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 16 meters (52 ft) high, with 14×24 m (46×79 ft) steel archways, modular buildings, fuel bladders, and equipment. Indifferent buildings within the dome housed instruments for monitoring the higher and decrease atmosphere and for numerous and complex 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 at the edges and kind a thermal blanket, which insulate the buildings. Two big enclosed domes are linked collectively, and with a number of smaller domes, they provide habitats for plant species from around the world. The primary dome has a tropical atmosphere, and the second a Mediterranean environment. A pc-managed environmental control system regulates the temperature and humidity in every dome


Geodesic domes have many drawbacks, particularly the place they are used to provide dwelling accommodation. The construction has an awesome many intersecting surfaces, compared with conventional structures, and all of those should be waterproof.

The surface covering is a problem due to the steady series of flat areas, each joined on a number of sides, and falling away to kind the surface of a big curve. Access for repair and maintenance is troublesome as nothing is flat, there is no ridge, and relying on the supplies, may have even better than regular care to keep away from damage. The need to let light in and lack of suitable flexible materials can be a problem. Flexing of constructions 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 house slightly more tough to use. The simplest roofing technique is the tile or shingle. This runs into problems close to 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 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 turned coordinator of the building of 17 domes at Pacific High School, and in 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 year, Kahn decided domes didn’t work well: He calls domes “smart however 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 major wastage when chopping the triangular sections often used.

Windows will be 10 to fifteen occasions more expensive.

Labor costs are high for wiring.

The interior shape makes internal walls more troublesome to construct.

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