The dome’s geodesic shape combined with the steel reinforced concrete exterior allows for such a guarantee. Ai’s standard design will accommodate up to 225 mph hurricane winds, F4 tornadoes and 50 lb. snow loads. In almost 40 years, Ai domes have survived all major USA hurricanes (Andrew & Katrina), tornadoes, a Hawaiian earthquake, and a 30″ in diameter hickory tree impact
with no structural damage. To read a recap of the Ai dome and acts of nature, view on Nature
The State of Florida requires Insurance Companies to offer reduced rates to homes that have high wind mitigation features. The American Ingenuity dome meets and exceeds these requirements. One of Ai’s client’s hurricane insurance premium went from $850 to $90 after he had his dome & windows/doors/shutters inspected and a Uniform Mitigation Verification Inspection Form was completed by a Qualified Inspector.
Manufactured dome homes are constructed using a triangular network to form a spherical shape. This method provides for a free span, self-supporting structure requiring no internal supports such as roof load bearing partition walls. This allows for maximum flexibility of floor plan design and utilization of interior space.
As an architectural form, the dome is one of the strongest structural forms devised and built by man. Domes that were built centuries ago enclose many of the great cathedrals of Europe. Domes are structurally superior to rectilinear enclosures. The partial sphere is an aerodynamic shape that is very stable in high winds and can withstand heavy snow loads. For these reasons, residential domes greatly exceed the structural requirements of the major building codes in the United States.
One of the most exciting architectural environments ever designed, a dome brings its best attributes to your home. It delivers a rewarding living experience filled with warmth, light and open space to those who accept the challenge to build and live in their own dome.

Went through Hurricane Andrew & a Tornado at the same time
with no structural damage.
Minor Damage Due to Horse Trailer Impact
In August 1992 American Ingenuity domes were put to the ultimate test of strength when they faced the wrath of Hurricane Andrew as it slammed into south Florida. Winds at the nearby Tamiami airport were clocked at 212 mph, spawning over 100 tornadoes within the storm and leaving practically everything in its wake leveled. Nearly 200,000 people become homeless overnight. Even a tower at the Turkey Point Nuclear Power Plant, designed to withstand 200-mph winds, was irrevocably damaged by this fierce storm. We were not surprised, however, when we learned that our domes survived – in great contrast to the thousands of conventionally built houses of their neighbors. On Key Largo, just 20 miles south of the eye of the storm, an Ai 40′ dome faced the brunt of the storm. Built on pilings near the Atlantic Ocean, it was exposed to relentless high winds and driving rain. Unlike houses and commercial buildings in the surrounding area, it sustained absolutely no damage.
Above is picture of a 45′ American Ingenuity dome home that was in the direct path of the devastating storm, bearing the worst Andrew could deliver; yet it suffered no structural damage. A two wide metal horse trailer was impelled against the dome leaving a paint skid marking on the dome where the trailer slide around the dome to the other side. The horse trailer caused a crack in the riser wall and a chunk of concrete to break loose. The dome owner, caulked the crack and mixed up fiber concrete and filled the chunk and then painted the area.
Due to the type and direction of the debris scattered around the dome’s neighborhood, an engineer from the Federal Emergency Management Agency (F.E.M.A.) surmised that a tornado had struck the area. The engineer’s own Alabama home had been hit by a tornado a few years ago, so he was impressed by the integrity of the dome on an emotional as well as a professional level. The dome structure had withstood not only the force of a hurricane but a tornado as well. The incredibly intense winds ripped open double entry doors and 12′ sliding glass doors, which had been covered with protective plywood sheathing. Even though the wood and glass doors of the entryways succumbed to the wind and allowed interior water damage from the rain, the dome itself stood strong.
SUPER-ENERGY EFFICIENT DOME HOMES
Save 50% to 60% on your heating & cooling costs
Ai domes protect your wallet by saving you 50% to 60% off your heating and cooling costs. The major reasons for low utility bills are reduced surface area of the dome and its thick insulation uninterrupted by wood. The insulation consists of a seven inch block of rigid R-28 expanded polystyrene (E.P.S.) which is comparable to 11 inches of fiberglass batting. This means the walls of a conventional house would need to be built with 2×10’s and still not have as much insulation as is in the Ai wall.

American Ingenuity’s Florida dome offices are a 45′ dome connected to a 34′ dome of 3,700 sq.ft. utilizing all electric power. In the hot Florida summer months, Ai’s offices can be cooled to 76 degrees for less than $55 a month.To view annual charts and 2013 electric bills for Ai’s offices, click on Office AC Costs. A 34′ Ai dome home of 1,200 sq.ft. located in Melbourne Florida can be cooled to 76 degrees for less than $22 a month in the hot Florida summer months. To view the home’s annual charts and 2013 electric bills, click on 34 ft Dome AC Costs. In colder climates your dome will be even more energy efficient.
The insulation is not interrupted by wood and there is no wood in the home’s exterior walls to rot or burn or be eaten by termites. During the panel assembly a temporary wooden rib system is used. Once all the seams between the panels & the entryways & dormers are concreted, the wooden rib system is removed with most wood recycled for interior framing & second floor knee wall perimeter framing. The dome is self supporting with no need for walls to support its shell. The exterior of the dome is steel reinforced concrete with no shingles to blow off in high winds. Paint the exterior concrete with concrete primer & paint.

Klaus Kolb’s South Carolina Ai concrete dome house earned EPA’s Energy Star. Home Energy Partners certified his home used 61% less energy than in comparably-size housing. To lean more, view Kolb Info. He installed a geothermal cooling & heating system. Klaus’s 2003 total monthly average energy bill was $49. This includes the electricity and propane costs for his entire 1,600 sq.ft. – 40 ft. dome.
