Green eco-friendly custom homes and interiors by Solaleya Designer Patrick Marsilli proposes a revolutionary solar structure Passive solar energy: Rotate your house away from the sun in summer to cool down and towards the sun in winter to warm up (on demand or automated rotation system). Optional Integrated solar panels to store energy as well as several possible ecological options for better energy efficiency. Structural strength: Anti-cyclonic Its aerodynamic form has proven resists without any damage to a wind up to 240km/hour (Taiwan Domespace resisted Cyclone Tim in 1994 and some others without deterioration). Anti-seismic The seismic ray that would make a 10 story building collapse turns around the ring gear of fixation without finding any perpendicularity. Every Domespace is erected over an elastomeric belt that works as a "silencer block"... like a piece of rubber that cushion vibrations. Arches are solidly anchored to a steel ring gear itself fixed to a pedestal made of reinforced concrete. Unparalleled structural integrity Pleasant habitat:

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. I used colored stickers on the tubes to mark the different lengths -- red for the long ones, violet for the medium lengths, and green for the short ones. 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: 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. It might be possible to suspend a tent skin or mosquito netting inside, or pull a stretch cloth over the outside and shoot foam. Tools: a pocket knife and string. 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.

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. If this is your first dome, the 2 or 3 frequency domes are recommended. 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 10: Break Time! Woo Hoo!

Frameless Geodesic Dome What is it? It’s a frameless geodesic dome designed to be easy to fabricate and build. It is 18 feet wide at the widest point and about 13 feet tall. It feels very spacious for it’s 209 square foot floor. The dome shell is built out of 3/16” corrugated plastic and 3/4” blueboard foam insulation. There is no frame in this dome. The dome has a radial 2x4 floor system held up by cinder blocks. It has electricity and is heated with a single electric radiator and is cooled with an exhaust fan and small window sized air conditioner. The materials are all easily attainable and it cost about $2100 to build it at the time. The dome shell is also extremely easy to disassemble making it a portable structure. Hacking housing If I want to spend my time writing blog posts, exploring new programming languages, and other things that I want to do but I am unlikely to get paid for, it’s helpful to opt out of certain common expenses. Advocacy The short construction time of this dome is remarkable. Solar gain

Sustainable Domes - Geodesic Dome - Aquaponics Domes :: Home 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. Beginning in 1970, Monolithic Domes have been built and are in use in virtually every American state and in Canada, Mexico, South America, Europe, Asia, Africa and Australia. Monolithic Domes are neither restricted by climate nor by site location. Monolithic Domes are flexible.

Domerama How to Build a Monolithic Dome Monolithic Domes are constructed following a patented 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. Step One: The Monolithic Dome starts as a concrete ring foundation, reinforced with steel rebar. Step Two: An Airform – fabricated to the proper shape and size – is placed on the ring base. Step Three: Polyurethane foam is applied to the interior surface of the Airform. Step Four: Steel reinforcing rebar is attached to the foam using a specially engineered layout of hoop (horizontal) and vertical steel rebar. Step Five: Shotcrete – a special spray mix of concrete – is applied to the interior surface of the dome.

100' Geodesic Dome for Aquaponics The bigger a dome gets, the better it's energy efficiency. Thank you for viewing my entry. I will post Instructables for all of the different aspects of the project as we complete them. When I am asked about building an aquaponics center that has an area of almost 8,000 square feet, I always have the same answer. With domes, bigger is better. In "Critical Path," under Geodesic Dome efficiency, Buckminster Fuller says: "Every time the linear dimension of a symmetrical structure is doubled (ie. 1 -> 2) the surface area of the enclosure increases at a two to the second-power rate (i.e., 2^2). With a 100' diameter dome, we will have almost 8,000 square feet to set up our aquaponics system. Couple that with it being twice as hard to heat and cool, and you may begin to see the picture. The prize money rounded to $100 (with tax:) 1760 6ft. 2x6's - $2800 616 Hubs - $25,000 *note* I edited this up from $5,000 as I got the quote back after contest closed 8,000 sq ft.

Dan's dome homepage One of the tricky things is to get all the paperwork & contractors organized so things happen in the proper sequence. The easy (and more expensive) way to go about this is to simply hire a builder to take care of everything for you, or you can act as your own general contractor and hire all the workers yourself, or, if you're handy and have a LOT of free time, you can do all the work yourself. I opted to go the second route, and save only the dome construction and a few other easy tasks for myself. We were lucky in that we already knew, and trusted, just about everyone else we needed to finish the job.

Eco-Dome: Moon Cocoon - Cal-Earth Building Designs The Eco-Dome is a small home design of approximately 400 square feet (40 sq. meters) interior space. It consists of a large central dome, surrounded by four smaller niches and a wind-scoop, in a clover leaf pattern. Learning and building an Eco-Dome is the next stage after building a small emergency shelter and provides hands-on learning experience in the essential aspects of Superadobe construction. It's small size of approximately 400 square feet (interior space), makes it a manageable structure for the first time owner builder. The finished "very small house" is self-contained and can become a small guest house, studio apartment, or be the first step in a clustered design for community use in an Eco-Village of vaults and domes. Built from local earth-filled Superadobe coils (earth stabilized with cement or lime).Tree free.Maximum use of space through alternative options. Note: The Eco-Dome plan is a part of the Cal-Earth educational and research program.
