Geodesic domes

Who and why was invented the geodesic construction?

Buckminster Fuller - philosopher, mathematician, engineer, historian and poet, invented and patented the geodesic dome in 1951. Anticipating a construction boom and the depletion of land resources due to increased Earthlings population he invented ways to achieve the greatest results, with less labor and materials. He also drew attention to shortcomings and problems of traditional construction in comparison with the genial  simplicity and durability of natural origin construction. Crimson in idea of creating a construction similar to the natural, he began experiments in spherical geometry in 1940! Today, geodesic domes are recognized as the MOST practical building systems known to us!

Why geodesic structure saves building materials?

The main factor affecting the efficient use of materials and energy in construction - is a shape. Imagine a soap bubble. The sphere represents the smallest amount of material needed to cover the surface of this volume. Hemisphere has become one of the most effective known forms to cover a given residential or industrial area.

Why geodesic structures saves energy expended on heating and cooling?

The answer again lies in its own geodesic structure form. The smaller outer surface (walls and roof) total area have the higher efficiency of energy consumption for climate control in the building inside. Exterior area of the dome is almost a third less than exterior area of parallelepiped with the same residential area. The surface area exposed to the environment has more influence in power efficiency than the putty quality in the seams and the walls thickness. In addition, heat loss from the basement of the building mainly depends not on the floor area, but on the length of the perimeter. Dome house with a smaller proportion of perimeter to area loses less heat through the foundation, than square or „box” like house. Effective air exchange inside the dome contributes to even greater savings on heating and air conditioning; curved surface of the dome facilitates natural air flow inside. Outside the dome, due to aerodynamic effects design wind bends around the dome with less resistance. For comparison, the square house; is a flat barrier to the wind, creating a positive wind pressure on the one side, and the sparseness or the negative pressure on the opposite outer surface, which creates drafts drawn out of the room warm.

Why do geodesic structures so strong?

In many parts of the globe geodesic constructions have stood in the strongest hurricanes and earthquakes, because its have the natural design specificity. Geodesic domes for over 25 years successfully applied to the Antarctic radar installations, where wind speed reaches 200 km / h. Spherical design natural form has a strength, because stress is distributed evenly at all construction points. Dome shape allows evenly distributed stress of the earthquake, wind or snow gravity throughout the all structure. Components triangular geometry adds the strength to the dome shape.

What other Geodesic constructions advantages compared to traditional housing?

Interior features a dome construction allows much greater layout freedom, cathedral ceilings, uniform distribution of light, heat and sound. Dome has excellent optical characteristics as the spherical shape amplify light, while the rectangular constructions absorb light. In many cases, inside the dome is lighter than on the street, even without internal illumination. Acoustic benefits include uniform sound distribution, the absence of sound resonating and 30% less of ambient noise.

How much  is the building costs of geodesic dome construction?

As we would like to give an exact amount, we still could not do it. Starting in basement (depth, the presence of the cellar, etc.) and to trim, also interior parts, there are too many variables in construction. What we sure know - this is a golden rule, that the construction square meter in dome structures costs at least 20-30% cheaper than in rectangular houses. And with regard to industrial constructions up to 40% cheaper.

What advantages are of dome houses design?

Since we are talking about a circle, the dome design have endless potential for the internally and externally project individualization. Internal walls, doors, etc. can be located anywhere, without strength compromising. Due to the fact that the natural load distribution allows the construction of five extensions, then varying its size and location depending on needs, we can create an infinite number of original design options. In addition, the dome houses owners mark sense „of grace and lightness” inside such houses. That may be associated with full compliance with the ergonomics standards and „feng shui”; constructions inspired by nature.

What types of foundations used for the dome?

Type of foundation for the dome structure is determined by the standard factors: the type of soil and its physical and mechanical properties, the depth of frost penetration, depth of groundwater, topography and local construction requirements. Our architects, after inspection of the proposed construction and examination of soil will always be able to offer acceptable options. Basically the foundation for the dome structure differs from the ordinary only in form and material consumption. Due to the dome construction lightweight and the ring-shaped base their required 25% less.

What is the extensions and how to use them?

Additional living space can be added to the dome first floor due extensions to the construction. These extensions could be added to any of the dome five natural openings without stiffness loss. Extension can be used as domes multiple, as construction of covered terrace, as entrances, sun decks, dining rooms, pools, greenhouses, planetariums, etc., increasing almost doubled the existing area.

What is panoramic mansard?

Panoramic mansrd is easily installed option on the top of the dome, which can improve the natural lighting and ventilation in your dome house. Just offering the possibility to create a little room with a view of 360 degrees, on the third floor. You can order stairs in variety options to access the panoramic mansard. To add panoramic mansard to the dome construction, we raise the upper roof part to one meter height. Struts form five rectangular frames, which allows the use of conventional windows.

Which windows can be used?

The dome construction design for a wide range of windows different shapes and sizes. The first option is triangular attic window. On one or in groups of five or six pcs., they make the most of all available area of each panel. Triangular windows emphasize the stately form and emphasize the architectural uniqueness of the dome structure. Standard rectangular windows can be used to build the dome, where they could be installed vertically in the lower dome section or in theextensions. Correctly aligned windows on the dome surface can save significantly on your home heating and lighting. Windows located on the winter sun trajectory following across the sky will provide passive heating room with winter sunlight. And in summer will not allow to warm rooms with sun direct rays. Practical recommendations for the passive heating and cooling use coupled with the passive brightness control you will get into your project discussing with the architect.

What dimensions of the proposed dome constructions?

Our standard plans ranging from 5 to 30 meters in diameter. These dimensions are used as standard and also with individual projects. On the individual customer`s request we are able to build a dome up to 100 meters or more in diameter.

Houses for northern latitudes.

Our standard dome is constructed using a 150 - millimeter wooden board. For houses  with more stringent requirements for wind load and snow resistance, we can use the wooden boards in widths from 180 up to 250 mm. That will increase the walls thickness and their insulation. Suited for industrial canopies we use aluminum or steel pipe and aluminum or steel channel width of 200 mm, which can significantly facilitate the giant dome construction, and add strength to it. Some of our domes are constructed using steel pipe with means for glazing mounting.

Heating and ventilation systems.

These systems for the domes are not much different from the traditional, except for efficiency calculations, which usually requires 30-40% less power heater or air conditioner than a standard rectangular house. Do not forget that many of our projects include passive heating and lighting, using solar energy.
