3、 The Geodesic Dome (圆顶层 ) the House of the Future? R. Buckminster Fuller spent much of the early 20 th century looking for ways to improve human shelter by applying modern technological know-how to shelter construction, making shelter more comfortable and efficient, and more economically available t

4、o a greater number of people. After acquiring some experience in the building industry and discovering the traditional practices and perceptions which severely limit changes and improvements in construction practices, Fuller carefully examined and improved interior structure equipment, including the

5、 toilet, the shower, and the bathroom as a whole. He studied structure shells, and devised a number of alternatives, each less expensive, lighter, and stronger than traditional wood, brick, and stone buildings. In 1944, the United States suffered a serious housing shortage. Government officials knew

6、 that Fuller had developed a prototype of family dwelling which could be produced rapidly, using the same equipment which had previously built war-time airplanes. They could be “installed“ anywhere, the way a telephone is installed, and with little additional difficulty. When one official flew to Wi

7、chita, Kansas to see this house, which Beech Aircraft and Fuller built, the man reportedly gasped, “My God! This is the house of the future!“ Soon, unsolicited checks poured in from people who wanted to purchase this new kind of house, but Fuller was never able to get it into full production. This w

8、as due to many obstacles such as only union contractors were able to hook the houses up to water, power and sewers in many cities. However, because the houses were already wired and had the plumbing installed by the aircraft company, many construction trade unions made it clear that they would not w

9、ork on the houses. There were also in-house differences between Fuller and the stockholders. Fuller did not feel the house design was complete; there were problems he wanted to fix. But the stockholders wanted to move ahead. However, the main obstruction was obtaining the financing for the tooling c

10、osts, which were purposefully not included in the negotiations with investors. No bank would finance the project with union problems and stockholder battles. After the war, Fullers efforts focused on the problem of how to build a shelter which is so lightweight that it can be delivered by air. Shelt

11、er should be mobile which would require great breakthroughs in the weight-reduction of the materials. Technology would have to follow natures design as seen by the spiders web which can float in a hurricane because of its high strength-to-weight ratio. New shelter would have to be designed that assi

12、milates these principles and that was Fullers intent. One of the ways Buckminster Fuller would describe the differences in strength between a rectangle and a triangle would be apply pressure to both structures. The rectangle would fold up and be unstable but the triangle withstands the pressure and

13、is much more rigid in fact the triangle is twice as strong. This principle directed his studies toward creating a new architectural design, the geodesic dome, based also upon his idea of “doing more with less“. Fuller discovered that if a spherical structure was created from triangles, it would have

14、 incomparable strength. The sphere uses the “doing more with less“ principle in that it encloses the largest volume of interior space with the least amount of surface area thus saving on materials and cost. Fuller reintroduced the idea that when the spheres diameter is doubled it will quadruple its

15、square footage and produce eight times the volume. The spherical (球形的 ) 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 shelter

16、s have been built all around the world in different climates and temperatures and still they have proven to be the most efficient human shelter one can find. More specifically, the dome is energy efficient for many reasons: Its decreased surface area requires less building materials; exposure to col

17、d in the winter and heat in the summer is decreased because, being spherical, there is the least surface area per unity of volume per structure; the curved-in interior creates a natural airflow that allows the hot or cool air to flow evenly throughout the dome with the help of return air ducts; extr

18、eme wind turbulence is lessened because the winds that contribute to heat loss flow smoothly around the dome; it acts like a type of giant down-pointing headlight reflector and reflects and concentrates interior heat. This helps prevent radiant heat loss. The net annual energy savings for a dome own

19、er is 30% more than normal rectilinear (直线的 ) homes according to the Oregon Dome Co. This is quite an improvement and helps save the environment from wasted energy. Domes have been designed by Fuller and others to withstand high winds and extreme temperatures as seen in the Polar Regions. Many dome

20、manufacturers offer various designs in geodesic dome housing with little assembly time required. Some houses can be assembled in less than a day with others taking up to six months. Many also come in dome kits that buyers can build themselves or with the help of friends. R. Buckminster Fullers first

21、 worldwide acceptance by the architectural community occurred with the 1954 Triennale where his cardboard dome was displayed for the first time. The Milan Triennale was established to stage international exhibitions aimed to present the most innovative accomplishments in the fields of design, crafts

22、, architecture and city planning. The theme for 1954 was Life between Artifact and Nature: Design and the Environmental Challenge, which fit in perfectly with Fullers work. Fuller had begun efforts towards the development of a Comprehensive Anticipatory Design Science, which he defined as, “the effe

23、ctive application of the principles of science to the conscious design of our total environment in order to help make the Earths limited resources meet the needs of all humanity without disrupting the ecological processes of the planet.“ The cardboard shelter that was part of his exhibit could be ea

24、sily shipped and assembled with the directions printed right on the cardboard. The 42-foot paper board Geodesic was installed in old Sforza garden in Milan and came away with the highest award, the Grand Premio. (1,036 words) 2 A geodesic dome is basically a spherical structure created from rectangl

25、es. 3 Every year, a dome owner may spend 30% less in energy expenditure than a normal rectilinear home one. 4 Domes are the environment-friendly building. 5 Some scientists set up domes in the Polar Regions. 6 In 1944, government officials were interested in Fullers family dwelling because it could

26、be _ . 7 Fullers family dwelling was not fully produced mainly because there were _ . 8 According to the description of Buckminster Fuller, the main advantage of a triangle in strength was _ . 9 Besides the feature of “doing more with less“, the spherical structure of dome can also allow natural _ w

27、ithout obstruction. 10 It has been proved that the geodesic dome is _ human shelter. 11 Fuller won _ in 1954 for his achievement in the 42-foot cardboard shelter.
