Geodesic domes:
Facts n Principles
Nature is not to be conquered or opposed, but she is to be regarded as a model of applied principles: Nature always does things in the most efficient and economical way. We need to learn how nature makes design decisions. One of the startling things about the so-far-discovered principles is that they do not conflict with one another. Universe works as an harmonious system-instantly regenerating as if it were the minimum perpetual motion machine. To be in tune with Universe, our designs should be regenerative.
The current, overused word “Sustainable” comes close.
R. Buckminster fuller
Emergency Temporary Shelter and habitation was one of the earliest problems addressed and solved as part of Buckminster Fuller's comprehensive Anticipatory Design-Science strategy. The approach was two-part.
The spherical structure of a dome is one of the most efficient interior atmospheres for human dwellings because air and energy are allowed to circulate without obstruction. This enables heating and cooling to occur naturally. Geodesic shelters have been installed in all extreme climates and temperatures and they have proven to be the most safe, effective & efficient shelter possible.
In 1932 R. Buckminster Fuller famously philosophized: "Don't fight forces. Use them!" (Fuller, Shelter). A man of many trades -- architect, author, designer, futurist, inventor, and the second president of Mensa -- he applied this mantra throughout many aspects of his work. In particular, it is more or less the backbone of his studies of and theories on synergetics, an interdisciplinary science that explores the formation and self-organization of patterns in systems. Fuller believed that all experience could be communicated using geometric concepts, and further claimed that the natural analytic geometry of the universe is based on tetrahedra, or triangular pyramids. He explored these ideas through studies of the close-packing of spheres and tensile and compressive stabilization models, noting that tension and compression are not opposites, but rather complements that can be found together; when the two forces are harmonious, continuous pull is balanced by equally discontinuous pushing forces. This synergy between compression and tension is what Fuller calls tensegrity, "a system that stabilizes itself mechanically because of the way in which tensional and compressive forces are distributed and balanced within the structure (Ingber 48-9). It is the underlying principle behind what is perhaps his most well-known invention, the geodesic dome -- a nearly spherical shell structure based on a network of triangular elements lying approximately on the surface of a sphere. On a grander scale, it is also a fundamental property of several self-assembled systems within the body, from the anatomical to the cellular to the molecular level.
• Geodesic tensegrity structures are "frameworks made up of rigid struts, each of which can bear tension or compression" (Ingber 49). These struts are positioned to hold the joints that make up the framework into fixed places, so as to stabilize the entire structure. Perhaps the most familiar example of these structures is the geodesic dome, immortalized by Fuller's golf-ball-esque Spaceship Earth building at Disney's Epcot. Influenced by the notion that the strongest possible homogenous truss is cyclically tetrahedral, a conclusion he reached from his studies of synergy, Fuller developed geodesic domes in the late 1940s to demonstrate the ways in which these ideas can be applied to housing and architecture.
• A geodesic dome is a sphere -- or ball-shaped structure comprised of a complex network of rigid rods connected into triangles, or tetrahedral, which form a roughly spherical surface. These triangular elements have local rigidity as well as distribute tension across the entire structure; each rod can withstand both tension and compression depending on where and how much pressure is applied, and the omnitriangulated surface provides an inherently stable structure. Moreover, the spherical shape of the structure encloses the maximal volume for the least amount of surface area. The geodesic dome's durability, minimization and efficient use of building materials, and mobile flexibility -- its modular structure makes it easy to transport and build -- were the source of its appeal to Fuller, who hoped it would provide a solution to the post-war or natural disaster ,housing crisis’
• Why do geodesic structures conserve energy for heating and cooling?
• The answer again lies in the shape of the geodesic structure. The lower the total outside surface area (walls and ceilings) the greater the efficiency in energy use for heating and cooling. A dome has approximately one-third less surface area to the outside than a box-style structure. The amount surface area exposed to the elements has a much greater impact on energy efficiency than insulation values. Additionally, heat loss from the foundation of a home is generally more dependent on perimeter length than floor area. A dome, having a smaller perimeter/square footage ratio than a box-style home, will lose less heat from the foundation.
• Efficient airflow inside that dome adds to the energy savings further; the curved surface of a dome provides a natural circulation of internal air. Outside the dome, the shape of the dome provides an aerodynamic effect; wind passes over the dome with less resistance. In comparison, a box-style structure provides a flat barrier to wind, creating positive wind pressure with air infiltration on one side, and suction, or negative wind pressure, with internal air exfiltration, on the opposite external surface.
The net annual energy savings for a dome owner is 30% less than normal rectilinear homes according to the Oregon Dome Co. This is quite an improvement and helps save the environment by conserving energy and resources. Domes have been designed by Bucky and others to withstand high winds and extreme temperatures as seen in the Polar regions.
Despite these facts, domes are hugely under-utilized. Contemporary construction methods are not based on engineering but on tradition; approaches of old which, with the passage of time, have outlived their usefulness in very essential ways.
Fewer Materials Means Great Savings
When constructing a dome, we are not buying and installing expensive materials for the purpose of holding up other expensive materials! A dome is self-supporting! The Geodesic Dome has 38% less surface area than a rectilinear structure of the same square footage. No other structure can match the qualities of the Geodesic Dome for strength, efficiency and structural integrity. According to the University of Minnesota’s Underground Space Center, the immense strength of the structure makes it ideal for earth-sheltering.
Generalized adaptability is needed to cope with large changes in the environment. Here lies the present chief peril of the human passengers on Spaceship Earth

There is a lot of information out there on the internet, I encourage you to Read his
Story and how he came upon his life choices n discoveries.
Buckminster Fuller’s universe
His life and work by
Lloyd Steven Sieden
Isbn# 0-7382-0379-3
Check your local libraries for his books he wrote 32 books between 1932 and 1983!!! He did this all for the benefit of all humanity. His influence on us and the world has been started and it will continue. It is my goal to share this incredible find with all of you who find this information. No Time shall be lost by studying and reading his works.
The volume of a sphere is:
V = (4/3) * Π * r3
where Π (pi) = 3.14159...
and r is the radius of the sphere
in the end decide for yourself and do your own research
