Sustainable Domes - Geodesic Dome - Aquaponics Domes :: Home Chapter 9: Mathematics -- Build a homemade geodesic dome A Geodesic Dome Some years ago I built a geodesic dome out of ½ inch galvanized steel electrical conduit, to serve as an aviary for chickens and small parrots. I wrote a computer program to calculate the proper lengths of steel tubing, and draw the diagram shown below: The dome is made from three different lengths of tubing. The ends of the tubes are smashed flat with a hammer, and then holes are drilled in the flat ends for a bolt to go through to connect up to six of the tubes together. For this project, something a little more modest in size is required. For the first attempt at a smaller dome, I used bamboo kebab skewers and gumdrops. You will need these materials for the gumdrop dome: 90 skewers 7¾ inches long 85 skewers 7½ inches long 80 skewers 6½ inches long 11 green gumdrops 15 orange gumdrops 50 red gumdrops Cellophane tape Click on photo for a larger picture Next, five medium sticks are stuck into the red gumdrops, and the pentagon is no longer flat.

Build your own Bamboo Domes This is page 95 of "Domebook Two", a book that was published in the 70's and is very hard to find. It was written by Pacific Domes (not the same as Pacific Domes), and I was able to find it at the local library. Bamboo grows fast, is free material for a dome framework. Dome Assembly The geodesic dome, as shown in the assembly diagrams, contains two different joints: a B joint which occurs at the vertices of all pentagons formed, and an R joint which occurs at all other points. Cutting and Measuring the Members There are only two different lengths of members used in the erection. For a 5/8 dome, 80 B members and 90 R members are required. A line of color can be drawn around the bamboo members at each measuring point. Cross Assembly With 12" extra on the end of each stick, there'll be a 24" overlap when the crosses are assembled. Cross Tying Stage 1 Assembly The first stage in the assembly of the dome is the construction of the pentagons at the top of the dome. Stage 2 Assembly Prop It Stage 3
Domerama Conduit Dome Tips Conduit, or EMT seems to be the material of choice for domes at Burning Man. Conduit is easy to work with, relatively inexpensive, and plated so painting isn't necessary. This page will provide tips for making conduit framed domes. STEP 1: Deciding on a frequency The first thing you need to do is figure out what type of dome you want to build. STEP 2: What Size? STEP 3: Calculating Strut Lengths This is where the Dome Calculator comes in. Step 4: Eliminating Waste This part is tedious, but worth the effort because it will save you money and you won't have to feel bad about throwing away tons of wasted pipe. Step 5: Cutting the struts Cut the tubes according to the strut factors plus 1½". STEP 6: Flattening the ends OK, there are a few ways to do this part. Step 7: Drilling Holes To drill the first hole in each strut, cut a V groove in a 2 X 4 six inches longer than the longest strut. Step 8: Bending the Struts Now the struts need to be bent to the correct angles. Step 10: Break Time!
Monolithic domes Monolithic dome office Monolithic Domes are constructed following a method that requires a tough, inflatable Airform, steel-reinforced concrete and a polyurethane foam insulation. Each of these ingredients is used in a technologically specific way. This technology was developed by the Monolithic Dome Institute (MDI). The domes can be designed to fit any architectural need: homes, cabins, churches, schools, gymnasiums, arenas and stadiums, bulk storages, landlord dwellings and various other privately or publicly owned facilities. The dome, when finished, is earthquake, tornado and hurricane resistant (FEMA rates them as "near-absolute protection" from F5 tornadoes and Category 5 Hurricanes).  Ecoshells MDI has also developed the technology to build so-called "EcoShells". EcoShells are easy to build, easy to teach others to build and fast to construct. It has been estimated that Haiti, for example, needs approximately 200,000 EcoShells to house up to 1 million people.  See also
El barro, las manos, la casa. Email+ 1Email Esta obra, dirigida por Gustavo Marangoni, es un gran documental didáctico sobre construcción natural.Filmado principalmente en la localidad de El Bolsòn, provincia de Rìo Negro, sur de la cordillera Argentina; fue realizado con el apoyo de la secretaría de Cultura de la Presidencia de la Nación. Y fue declarado de interés por el programa “Arquitectura y Construcción con Tierra” de la Facultad de Arquitectura, Diseño y Urbanismo de la Universidad de Buenos Aires. Se trata de una mirada general a este tipo de construcción: sus características, su historia, los prejuicios que tenemos sobre la tierra como material de construcción, sus virtudes y también sus desventajas (y como superarlas). Jorge Belanko charla con vecinos aclarando dudas generales como por ejemplo, si es posible realizar este tipo de casas en zonas lluviosas como las nuestras, los diferentes estilos de construcción, la posibilidad de la autoconstrucción, entre otros temas.

The Monolithic Dome Monolithic Domes are constructed following a method that requires a tough, inflatable Airform, steel-reinforced concrete and a polyurethane foam insulation. Each of these ingredients is used in a technologically specific way. Our domes can be designed to fit any architectural need: homes, cabins, churches, schools, gymnasiums, arenas and stadiums, bulk storages, landlord dwellings and various other privately or publicly owned facilities. Monolithic Domes meet FEMA standards for providing near-absolute protection and have a proven ability to survive tornadoes, hurricanes, earthquakes, most manmade disasters, fire, termites and rot. They are cost-efficient, earth-friendly, extremely durable and easily maintained. Most importantly, a Monolithic Dome uses about 50% less energy for heating and cooling than a same-size, conventionally constructed building. Monolithic Domes are neither restricted by climate nor by site location. What does a community need and want in a school structure?
