Instead of buying washers for this project, we turned to reducing our waste and re-using the scraps from the metal strapping

Constructing Day 1!

It’s time to start building this wall. The process of making the Geodesic Dome on Day 1 (Thursday 26th of April). On day 1, we built half of the dome structure.

The Building Code of Australia & Geodesic Dome

The Building Code of Australia provides for certain structures which fall under what is called the “exempt development provisions”. Simply put, this means that each individual council can specify in their local rules what constitutes “exempt development”. Under councils “exempt development” provisions you are usually allowed to build a “shed” without applying for approvals for a structure under 10m2 and under 2.4m high

If you are required to submit plans to your local council, please get in touch with us about preparing any additional documentation that you may need to lodge plans with the council. NOTE:  Further information about your site may be required to support your application such as geotechnical soil report, site plan, contour information and possibly other information or consultant reports. Our friendly design team can assist you to complete and assemble additional information or plans specific to your project for minimal extra cost on an hourly rate.

If the “DomeShed” structure complies with these regulations you may be permitted to build such a structure WITHOUT needing to apply for a “development application or submit for any further approval.

If you already have a shed in your backyard you may not qualify to build another one under the “exempt provisions” as you are generally only allowed one shed.

If the above is the case you can most likely get a permit to build a “Studio” which will require you to submit the plans and specification to the council for approval. Please get in touch with assisting you with council documentation.

In this case, you will almost certainly be required to obtain Council Approval for a “Studio”

The above is relevant to building a dome using our fully engineered GRC/Polyurethane foam system and also to the ‘DreamDome’ FRP system.

In respect of the Bamboo dome system, we do not have a clear answer at this time. The system is being introduced to the Australian Building scene and although there is a raft of engineering data for bamboo reinforced concrete and also Ferro cement shell structures, there is no standard yet in Australia.

Case Study

Eden Project, 2001

Architect:  Grimshaw Architects

Inspiration Designed by Grimshaw Architects, our two Biome buildings - the Rainforest Biome and the Mediterranean Biome - each consist of several domes joined together, and are joined in the middle by the Link building.

The Core Architecture The word 'biomimicry' describes the process of humans borrowing designs and systems from nature to create their own technology. Jolyon Brewis of Grimshaw Architects did exactly that when he based the architecture of our Core education centre on the growth blueprint of plants. He used opposing spirals mathematically based on Fibonacci’s sequence (0, 1, 1, 2, 3, 5, 8, 13, 21, 34 ...) where every number is the sum of the previous two. The spirals on a pinecone, pineapple and sunflower, like the Core roof, usually represent two consecutive numbers in this sequence.The brief asked the architect for the building to be fit for purpose, future-proof, made with responsibly sourced materials, energy efficient, and constructed with minimal waste.

Design and materials The structure is made of double-curved glulam (glued laminated) timber beams (the timber is endorsed by the Swiss Forestry Stewardship Council).We traced the supply chain of the copper for the roof from a single Rio Tinto mine, known for its high environ­mental and social standards, all the way to Eden. This unusual initiative has led to much more work on the minerals supply chain.Elsewhere in the Core, you'll find recycled wood, plant-based floorings (Marmoleum from flax, carpets from maize), and concrete from china-clay sand (low carbon footprint). The little green tiles are made from recycled Heineken bottles.

Understanding Geodesic Sphere

Formulas: Golden ratio = (1+sqrt(5)) / 2 Golden Rectangle Length = Width*Ratio Golden Rectangle Width = sqrt(4*Sphere Radius^2/(1+Golden Ratio^2))

In geomety, a golden rectangle is a rectangle whose side are in the golden ratio.

Phi (Greek letter) is approximately 1.618

Revit Adaptive Component - Dome Modeling

In order to understand the concept and formulas of a geodesic sphere. We have decided to model a dome in Autodesk Revit with 4 key steps:

1. Create Golden Rectangle 2. Create Structure using 3 Triangles Circumscribed 3. Create Icosahedron using Adaptive Triangle 1V frequency 4. Create Geodesic Sphere using Adaptive Triangle 2V frequency

Create Golden Rectangle

Draw a rectangle and add Length and Width parameters

Using Golden Ratio Formulas

Create the Structure using 3 Triangles Circumscribed

Offset element dots and add the Golden Rectangle

Add parameters - RotationEW - RotationNS - Sphere_radius - offset - 3TrianglesCirsumscribed - PositionZero

Create Icosahedron using Adaptive Triangle 1V frequency

Create 1V Triangle using Adaptive points and save the family as 1VTriangle.rfa

Load the family into the 1V frequency screen and rotate clockwise around the 3 Triangles Circumscribed

Geodesic Sphere using Adaptive Triangle 2V frequency

Create 2V Triangle using 3 Adaptive points and setting parameters and save the family as 2VTriangle.rfa

Load the 2VTriangle.rfa into the screen

Using the 1V frequency Icosahedron, select all 1VTriangles in entire project and change them to 2VTriangle.rfa

Adjust Rotation of the sphere to create the dome

Case study

Buckminster Fuller's Dome Home, 1960

Architect:  R. Buckminster Fuller

The Dome home was built on 19th April 1960 for Fuller and his wife. Fuller, who designed the dome home in 1954, saw the dome home as a low-cost, safe, and accessible housing structure.

Eco-friendly: Dome homes are incredibly green in term of costing, building materials required. Dome home uses approximately 50% to 70% fewer materials to construct than standard homes within the same volume.

Strength: The geodesic domes are lightweight structures, yet it's a stable construction as the pressure applied on it is distributed around the entire structure. The dome homes have an advantage over standard houses when it comes to an earthquake and high winds. Due to the aerodynamic shape of a geodesic dome and the absence of suction elements,  the dome provides the best protection against the winds.

Sustainability of Geodesic Domes

Sustainability of Geodesic Domes

Geodesic domes are considered sustainable for a number of reasons. Firstly, they have relatively higher energy efficiency. Secondly, they can be made without using wood. Thirdly, they are resistant to all kinds of natural calamities. Finally, they produce little or no waste.

High Energy Efficiency

Extravagant energy consumption puts a strain on earth's natural resources. This strain has produces a negative ripple effect. Contemporary housing structures are not designed to improve energy efficiency. With geodesic domes, however, you are guaranteed a 50% or more increase in energy efficiency. It costs lower to light or heats up a geodesic dome. This not only reduces the costs of energy consumption but also minimizes the environmental footprint.

History Of Geodesic Dome

The first dome that could be called “geodesic” was designed after World War I by Walter Bauersfeld. The geodesic dome is extremely strong for its weight, its “omnitriangulated” surface provided an inherently stable structure, and because a sphere encloses the greatest volume for the least surface area. 

In 2000, the worlds first fully sustainable geodesic dome hotel, EcoCamp Patagonia was built in Chilean Patagonia. The hotels dome design is key to resisting the regions strong winds and is based on the dwellings of the indigenous Kaweskar people.
