This dome home was owner built. The exterior is finished with interior finishing occurring as we post this article. As we receive interior finishing pictures we will update this gallery.

The home is three bedroom 2 baths with half bath in the link. The 40′ dome has 1,140 sq.ft. on the first floor and 567 on the second floor for a total of 1,707 sq.ft. The link has 151 sq.ft. The 34′ garage dome is 827 sq.ft. on the first floor with a possible future second floor of 428 for a total sq.ft. of 1,255. The master bedroom and master bath are on the first floor with two bedrooms and bath on the second floor.

Due to the three foot frost line, a three foot stem wall was built from Fox Block to get the footer below the frost line.

For those of you wanting to compare the Aidome Building Kit vs Deltec Home Kit, please take time to read and analyze info listed below.  Please compare kit costs and contents of each kit.  Instead of building a home from a Deltec wood kit,  consider building an Ai prefabricated concrete home dome kit.  To warm up the exterior & interior of the American Ingenuity (Ai) concrete dome; 1) paint the dome exterior light green or light tan.  2) install rock or wood on the framed walls under dormers & entryways and on the riser panels. 3) Install wood decks off the first floor entryways.  4) Install trellis with vines to conceal the fire resistant concrete. On the interior adhere oak to the dome shell drywall and install wood flooring, wood cabinetry.

We understand that it is important to compare various companies when it comes to designing and building your home, and that you may want to compare our concrete kit to Deltec homes.

Ai would like to do a comparison between both of our companies, so you can determine which home would be best for you. We want to offer you a comparison showing that Aidome building kits will offer you more for your money, be more energy efficient, offer better defense from the elements and have lower maintenance costs over time.

Please be aware that both AiDomes and Deltec do not install a foundation. That work is completed by a local foundation subcontractor near you. In Ai’s building plans are foundation pdfs detailing foundation dimensions.

Please note in the information below we are simply pointing out the differences in our products.  Deltec makes a fine product, but we at Ai feel we have superior home product.

Let us start with the kit:

·        Galvanized Steel Cables are included with the kit (for standard riser panel height design)

 

*Rods & Z plates for second floor are at a nominal charge per plan

 

The Deltec kit: As you can see their system is wood frame, it requires that the house exterior be finished with some sort of siding, and the roof shingled. Per their website, there is no mention of the inclusion of insulation, or drywall for the shell and attic area (there is mentioned as one of the top upgrades (i.e. additional cost) some sort of energy barrier for north & south facing areas of the home, not throughout the home).  Being wood, the wood exterior is subject to fire, rot and termites. 

With an Ai dome Kit:  When assembled, the prefabricated panels produce all the structural components, the concrete roof, all the insulation and all the interior drywall for the dome shell’s exterior walls and roof.  In addition, the dome shell carries a 225 mph wind and F4 tornado guarantee.  Ai’s panelized system does not contain wood or steel framing (ribs) to interrupt our standard R28 insulation. There is no exterior wood to burn or rot or for termites to eat.  As an added bonus, there is no roof to blow off in high winds, and has a noncombustible fire resistant concrete exterior.  (Pressure Treated wood is used to frame the walls under the entryways and dormers to accept your locally purchased doors and windows.  During Kit Assembly a temporary wooden rib system is installed to support the panels. However once the seam areas between the panels and the entryways and dormers are concreted, the Aidome is self-supporting and the rib system is removed.)

  • Although all homes require exterior maintenance, an Ai dome (when erected), simply requires painting – there are no shingles to replace. Whereas a traditional home, as well as the Deltec kit would require repair and/or  replacement of the roof, as well as maintenance/repair and/or replacement of the siding.
  • In regards to the cost to build, both Deltec and Ai are kits, they are not complete houses, they are the shell of the structure,  this is done by local contractors (Ai knows of an  Independent Kit Consultant to assist your contractors with shell assembly).

Ai Concrete Dome Kit Home vs Shipping Container Home

After reviewing several sites regarding converting a shipping container into a home and what the American Ingenuity (Ai) Dome Building Kit offers, we have the following comparison to share.  When comparing companies housing products, please compare apples to apples, not just the container cost.  

  1. Do the other companies back up their product against Hurricanes and Tornadoes?  American Ingenuity offers a warranty up to a 225 mile an hour winds and or F4 tornado. Click on, Aidomes & Acts of Nature to learn more.
  2. To reach the 780 sq. ft. of living space (average 27′ dome)  will require two to three 40 ft. containers, at an average price for used containers (in good shape, another issue posted) of $2,000. New containers run between $4,500 and $6,000 that is $13,500 (for 3) minimum before shipping. The closest shipping (for this Florida example) for a container would be Miami.  Current shipping costs are about $800 per truck within Florida ($2,400).  So your investment before your retrofit would be over $15,900!   Adding the retrofit, insulation and drywall will add another $10,000 or more. (not including custom windows, doors, electric, plumbing etc.) For an estimated total of $25,900 (before sales tax). Remember material costs to finish a home is over 50% of construction costs. Prior to Florida Sales Tax, the American Ingenuity dome kit w’ shipping cost to a Florida site based on the 27’ Kappa 11 plan is $26,152, a difference of only $252 and you receive a home with greater strength – 225 mph wind & F4 tornado warranty on the dome exterior walls.   Please see Ai Pricing Chart below.
  3. When looking at  container conversion, how is the interior of the home finished?  Do you have to cut and solder the units for windows, entryways and multiple units?  Do you need to tear the flooring out due to possible contamination (another potential problem)?  Attach the insulation and wallboard? Ai’s kit’s triangle and riser panels come with the R28 insulation and ½” thick DensArmor gypsum wallboard (by Georgia Pacific) already adhered with wallboard adhesive. After the kit panels are assembled, the drywall seams are taped with adhesive mesh tap and joint compound.  To blend the drywall seams and the drywall surface, skip trowel joint compound over the dome shell drywall.
  4. Does the product or kit contain insulation? What type, and what is the overall R-Value for energy efficiency? Our kits have standard 7″ thick rigid, nontoxic EPS giving the structure an overall R-Value of 28. From what we have read container homes have major insulation problems with both keeping the home warm in winter and cool in summer, which may present a problem in your area.
  5. Does the companies product have a finished exterior? If using a container then will you need to seal the container with nontoxic paint adding siding or stucco (many containers have lead based paint that needs to be properly sealed so not to contaminate you). The American Ingenuity (Ai) dome’s exterior is 3/4″ concrete reinforced with galvanized steel mesh & fibers with the seams between the panels & the entryways & dormers concreted on site. You do not concrete over the entire shell. After kit erection the concrete gets primed and painted.
  6. Like a container conversion, Ai’s dome panels contain no wood in them.  They are steel reinforced concrete, as opposed to solid metal which will/ can rust.
  7. Will the companies that do the retrofitting call your building department and verify the structure can be built on your site?  At no cost to our Buyers, we call their building department, email a generic set of building plans and talk to the Plans Examiner to assure the dome kit can be built.
  8. Do companies that specialize in shipping container retrofits, provide you with building plans (Ai’s current sale price for 27 Kappa 11 building plans is $851), engineer seal for your state (Seal for one dome on a slab is $600) and energy report  (Ai price to complete the report for one dome on a slab is $190)?  If so what do they charge? If they don’t provide these services, please be aware you will need to hire an architect, and an engineer to seal your building plans.  Just last week, a Florida Resident visited our dome offices and said that engineer sealed building plans for a four container home built in Florida would cost $8,000.

Please keep in mind that the cost to build a finished moderately priced home varies from state to state. As an example in Central Florida (based upon figures from Building-cost.net) the average cost to build is about $138.00 per square foot for a home that is 750 sq. ft.  This is not including the cost of land, land preparations, permitting/impact fees, and utilities. It would include all your interior finishing including kitchen,  HVAC systems and appliances and monolithic foundation (slab). So a home that is 750 sq. ft. would run about $103,000 to build (this would include the cost of our dome kit). The cost to build one of our kits runs about the same to build as a traditional home but our kit home has insulation comparable to  11” of fiberglass and has super-strength.  A traditional house would require 2×10 framing (see Finished Cost) to come close to our dome….but it would have wood interrupting the insulation while the Ai dome has no wood in or on the shell to interrupt the insulation, or to burn or to rot or for termites to eat.

WHY BUILD A GEODESIC DOME FOR YOUR NEW HOME OR BUSINESS?

Q: Why did the founder of American Ingenuity (Ai) in 1975 decide on the dome shape for his commercial dome to be built in Melbourne Florida and why did he choose to use fiber concrete instead of wood?  

A: The dome, or partial sphere, is a geometric form that encloses the greatest amount of volume with the least amount of surface area. Historically, massive domes constructed of stones, brick or concrete were common in ancient Greece and Rome. In modern times, Buckminster Fuller was the first to formulate geodesic principles for constructing a spherical surface by triangular subdivision. However nearly all of Fuller’s domes were built from wood framing with shingled roofs.

Ai’s founder, Michael Busick, did not want to build his Florida commercial dome out of wood and shingles because termites eat wood, hurricane force winds rip off shingles and a wood dome has an increased shingled roof area causing expensive reroofing costs every 11 or 12 years.  Instead Mr. Busick hired a University of Miami architectural professor, engineering students and director of the Florida Solar Energy Center to come up with building materials specifically to build the geodesic dome without wood or a shingled roof. The materials were concrete, mesh and expanded polystyrene (EPS) insulation. Back in 1976 the first Ai dome was built by propping up precut EPS panels, hand tying road mesh on the exterior of the EPS and guniting concrete on to the exterior.  Mr. Busick soon learned that guniting concrete over the entire exterior surface was a waste of concrete and labor.  This is why he invented Ai’s prefab panel.  Building an Ai dome from prefab concrete panels makes construction easier than stick built construction or pumping concrete on to an airform and results in the dome triangle and riser panels having a 225 mph wind and F4 tornado warranty and being super-energy efficient.

The panel concrete is a special formulation containing synthetic fibers and two liquid admixtures. The following is why Ai ships these same ingredients with the Building Kit  so that the concrete mixed on site which is hand troweled in the seams between the panels and on the entryway and dormer panels has the same properties as the prefinished concrete Ai applies at its Florida factory on the prefabricated panels.  Fibers in concrete work to reduce the formation of shrinkage cracks in concrete’s plastic state while helping to improve shatter resistance and reduce water migration. The result: tougher concrete. These ingredients improve the concrete’s characteristics, create super toughness, extend durability, make concrete impervious to water, give higher tensile and compressive strength, provide elasticity for expansion, and improve freeze protection. The concrete in your dome out performs other exteriors because of its specially developed formula. Because of its exceptional composition, it actually gains strength over the years. The exterior concrete adheres directly to the galvanized steel mesh and E.P.S insulation without the need of a bonding agent. The panel concrete is 3/4″ thick. The seam areas between the panels average two inch thick fiber concrete.

Why build a concrete geodesic Aidome from a building kit consisting of prefabricated concrete component panels versus a box shaped conventional house?  The dome, or partial sphere, is a geometric form that encloses the greatest amount of volume with the least amount of surface area.   During the past decade the home buying public has experienced increased Acts of Nature (tornadoes, hurricanes, fires), a substantial increase in the cost of construction, the cost of energy and the cost of borrowing.  As a result, there has been increased interest in the use of concrete kit home technology to help address these concerns. Many home buyers have discovered that the Aidome design offers a viable solution; as a result Ai has shipped dome kits into 47 USA states and 15 foreign areas.

As a building concept, geodesic dome construction translates into a highly comfortable and livable building that has a maximum of floor area enclosed by a minimum of materials. These features combine superior strength, superior energy efficiency and cost-effectiveness in a single structure.  In short, the building concept of a dome expands the range of simple and economic building options. The process of stacking the panels, overlapping/locking the galvanized steel mesh of adjacent panels and filling the panel seams with special fiber concrete, produces  1) the structural components of the home;  2) the finished concrete exterior surface;  3) installs all the R28 insulation; and  4) installs all the special shell ½” Georgia Pacific DensArmor Drywall that is moisture resistant and mold resistant (similar to green board).   Ai’s component panel building system is one of the most simplified ways to build a commercial or residential building on the market today.  

Why build a geodesic dome – Super-strength, super-energy efficiency, low exterior maintenance and fire resistant concrete exterior.  The geodesic geometry intersects to form triangular elements, which have local, triangular rigidity, and so distribute the structural stress throughout the geodesic sphere.  The triangle shape is the strongest shape known to man – it will not collapse whereas all other shapes can.  Manufactured domes 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.  One of the most exciting architectural environments ever designed, a dome brings its best attributes to commercial or residential needs.  It delivers a rewarding living experience filled with warmth, light and open space to those who choose to build a dome. 

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, Ai’s concrete domes greatly exceed the structural requirements of the major building codes in the United States and internationally.  One of Aidomes in the British Virgin Islands withstood Hurricane Irma’s 200 winds with no damage.  An Aidome in St Croix in 12 days went through two category five hurricanes with no damage to the dome.  An Aidome in South Carolina withstood the impact of a 30” in diameter hickory tree with no damage because the continuous galvanized steel mesh in the panels transferred the impact throughout the dome versus when a tree impacts a box shaped house the impact is localized in one area resulting in the tree slicing through the roof.  Ai gives a 225-mph wind and EF4 Tornado warranty on the dome exterior prefab triangle and riser panels.   This article explains more about dome strength.

Ai has stock plans for each of its ten different size kits which when assembled and finished with local materials, result in a tiny home of 172 sq.ft. to 3,000 sq.ft in one dome. Up to four domes can be linked to one dome to produce larger homes.  If a Buyer does not find a stock plan to fit their lifestyle our plans designers can modify or customize a plan from descriptions and sketches for a reasonable fee.   Building kits with Building plans cost from $20,000 to $67,000.  This pricing does not include the engineer seal on the plans (if required to obtain a building permit) or shipping or custom foundation plans.

Ai has made improvements in its entryway panels to result in the 30 ‘ – 48’ entryways having scratch coat of concrete on the underside and preformed lip edge for front of a beam that is poured on site.  Engineers with our Computer Aided Drafting Department have designed revisions in the building plans to comply with code as code has changed over the years.  The Assembly Manual is new and improved and is shipped with each dome kit purchase.

The Ai dome is more energy efficient than a conventional house: Why did an Aidome beat a passive solar house designed by Florida Power & Light (Florida’s nuclear-powered utility company) to win the Grand Aurora Award for Most Energy Efficient Residence in the southeastern United States?

  1. Because the dome’s 7” thick insulation is comparable to 10” of fiberglass batting (A conventional house would need minimum 2×12 walls filled with 10” of fiberglass batting and still not meet the energy efficiency of the Ai dome because the 2×12 would interrupt the insulation)
  2. the reduced exterior surface area of the dome is 30% less than a conventional house so there are less exterior walls for the air conditioning and heating to try to pass through.
  3. and because the exterior triangle and riser panels of an Ai dome contain no wood to interrupt the insulation.

The thick insulation allows cooling and heating bills to be reduced 50% to 60% over conventional houses utility costs.  (this link lists electric bills for Ai’s offices 45’ linked to 34’ dome – 3700 sq.ft. which can be cooled for less than $85 a month in the hot Florida Summer Months.)  The low utility bills can be achieved because the 7” EPS is not interrupted by wood and the dome has 30% less exterior surface area than a conventional house. To view utility bills for 1,075 sq. ft. Aidome home’s electric bills, please view 34’ Dome Home Energy Recap.   For northern climates, the insulation can be upgraded from 7” to 9” or R36.   (Because of the reduced surface area and all the shell panels having either R28 or R36 insulation, the Aidome will pass an Energy Report with double pane Low E glass.  FYI, it is even easier to heat an Aidome than to cool.  To cool a building –  heat generated from sunlight, refrigerator motor, dish washers, clothes dryers, computers, etc. has to be overcome; when heating the heat generated from these items is used.

Other advantages of the Aidome & its panel materials are:

Fire Resistant Exterior Concrete:  Why did two California home buyers, recently purchase Aidome building kits and pay shipping cost from Florida to California?  Their wood houses burned down in fires.  Ai’s panelized system does not contain wood framing (ribs) to interrupt the R28 insulation.  The prefab panels contain no wood to burn or rot or for termites to eat.  All prefab materials are noncombustible with the exterior of the panel being fire resistant concrete reinforced with galvanized steel mesh. 

Under the entryways and dormers, pressure treated wood is used to frame in standard windows and doors with lathe and exterior stucco covering the framed area.  Resulting in the dome and any exterior framed walls being covered with concrete.  The standard, high profile and garage entryway panels for the 30′-48′ kit sizes have been improved and now have a scratch coat of concrete on the underside and a preformed lip edge which folds up to make the front of a beam which is poured on site.  

FYI during kit assembly a temporary wooden rib system is assembled to support the panels.  The prefab panels compress against each other and are locked together with the steel reinforced concrete so after the kit is assembled, the dome is self-supporting and the temporary wood rib system is removed.  In a conventional house supports are needed to support the roof trusses and the roof; but not in the Aidome! The dome’s exterior walls are self-supporting.   

Environmentally Responsible:  Less than half the construction lumber & less than half the energy to operate than average houses.  Insulating foam is ozone protecting, nontoxic, expanded polystyrene (EPS). The EPS contains NO Chlorofluorocarbon (CFCs), no HBCD (hexabromocyclododecane), no TCPP (1-chloro-2-propyl) phosphate and is formaldehyde free.

Special Water Resistant & Mold Resistant Georgia Pacific DensArmor Plus gypsum drywall is installed on each prefab triangle & riser panel.  By the time the component panels are assembled it could rain. If Ai used conventional drywall, the paper matting when wet is a food source for mold growth and the gypsum crumbles.   The DensArmor gypsum drywall is moisture resistant and mold resistant.  DensArmor Plus High-Performance Interior Panels are noncombustible (as defined and tested in accordance with ASTM E136 or CAN/ULC S114) interior panels that consist of a moisture-resistant gypsum core with coated fiberglass mats. The fiberglass mats provide superior protection from incidental moisture.  The treated core and the coated facings made with fiberglass offer greater moisture resistance and improved dimensional stability than regular gypsum board. The product resists warping, rippling and buckling.  The DensArmor has zero flame spread and zero smoke development and complies with the 15 minute thermal barrier test as described in 2010 Florida State IRC Section R316.4.   Georgia Pacific’s Dens-Deck roof board is a patented nonstructural glass mat-faced, noncombustible, water-resistant, gypsum core panel.  Georgia Pacific does not add any flame retardant to its gypsum products.  The DensArmor contains no HBCD and no TCPP.    DensArmor Plus Panels are highly resistant to the growth of mold, and have scored a 10, the highest level of performance for mold resistance under ASTM D3273 test method. DensArmor Plus Interior Panels are the first drywall panels to be GREENGUARD indoor Air Quality Certified and GREENGUARD Children & Schools Certified for low emissions of volatile organic compounds (VOCs) by a leading third-party organization, GREENGUARD Environmental Institute.  In addition, DensArmor Plus interior Panels are the first drywall panels listed as GREENGUARD microbial resistant.  This listing means Dens-Armor Plus Panels, which feature fiberglass mats instead of paper facings used on the surface of traditional gypsum board products, resist mold growth.  The microbial resistant test is based on ASTM D6329, a testing standard set by ASTM International, which develops testing guidelines and procedures for building materials, products, systems, and services.

To install electrical wiring in the prefab panels, take a router or circular saw and cut a groove.  Either install conduit with wiring or install wiring in the groove.  Use expanding foam to fill the groove.  Cut the foam back flush and finish with fiberglass tape and joint compound.  To blend the taped areas to the smooth DensArmor drywall texture, skip trowel or knock down joint compound over the DensArmor.  Interior framed walls are finished like conventional housing.

Flexibility on floor plan layout design:  Since there are no load bearing walls or rectangular compartments, soaring spaces fill a dome.  The dome may be customized to suit the home buyer’s tastes and lifestyle from casual to formal.  Ai has stock plan layouts for each of its ten size kits.  If a stock plan does not fit the lifestyle, then we can modify or customize layouts from descriptions and sketches at a reasonable fee.   Ai Designs professional sets of blueprints, which contain from 13-20 sheets.  The Nomenclature Blueprint in the Building Plans shows the dome geometry with all the panels marked with letters and numbers which match the numbering on the prefab panels.   The number of sheets depends on the size of dome, foundation type and the type of entryways and dormers in the kit.  The blueprints contain dimensions to install the foundation and instructions for panel, dormer and entryway installation, etc.  Plans can be converted to metric for a small fee.    Under the entryway panels multiple windows or French doors can be installed. For example a 40’ dome with finished with local materials is a three bedroom/two bath size home.  Its entryways can have double French Doors and window on each side.  During plans design, we email elevation views of each type entryway, standard, high profile or garage, showing the rough opening size and recommended door and window sizes. Each elevation view has a to-scale ruler which allows for dimension measurement. Ai can design flue pipes, solar tubes, skylights, conduit to hold wiring for solar panels, etc. in the dome shell.  On site, a hole can be cut in the prefab panel – just do not cut within eight inches of the center of a seam.

The building plans have been improved to show symbols for the different length foundation rebar and revisions in how the framed wall under the entryway and dormer panels is installed.

Ai does not burden the price of the building kit with the price of the building plans, engineer seal, energy report.  If we did we would need to increase the price of the building kit 30%.  Instead Ai’s philosophy is that each buyer pays for the engineer seal and Rescheck Energy Report if those items are required by your building department to obtain a building permit.  Ai utilizes independent P.E. Engineers to seal the building plans for all states in USA.  The seal fee for one dome on a slab is $600.  The seal fee for one dome on a basement is $900.  Ai can complete a ResCheck Energy Report for $190 for one dome on a slab, $270 for one dome on a basement; after Buyer provides specific window and door specs..

Flexibility on types of foundations which can be designed:  The Aidome can be built on any type soil or terrain and be elevated to withstand flooding and water surge.  Ai’s standard foundation is a monolithic slab; however Ai can design custom foundations from basements, stem wall, elevated platform on concrete columns or pilings, etc.  To design custom foundations, the buyer of the building plans pays for Ai to hire a local engineer to review their soil report, what type custom foundation is to be designed, calculate load of the dome and interior floors, complete design details which Ai incorporates with their custom foundation blueprints.  Elevated Aidomes in the Florida Keys with stood Hurricane Irma winds and water surge with no damage.

Once Ai knows what type foundation is to be designed, we will ask the engineer for his fee to assist in the design of the custom foundation and his fee to seal the custom foundation plans. Ai completes a Plans Quote listing the engineer fees and Ai’s fee to design the custom foundation plans along with the dome building plans. Once the buyer agrees with the Plans Quote and pays in full for the plans, engineer fees, etc. Ai schedules the plans for design and emails proofs per the Plans Quote.

Low Exterior Maintenance:  The Aidome exterior is a shell of continuous concrete with nothing to rot, burn, rust, shrink, warp, replace or be eaten by termites.  There is no roof to blow off in high winds or to replace every 11-12 years. The exterior concrete is painted every 4-5-6 years with breathable elastomeric paint.

Building Permits on Concrete Dome:  Supply the property tax ID number and building department name and at no cost,  i will call the building department and email a sample set of plans to find out what is required to issue a building permit.  If required an engineer seal can be purchased through Ai for the building plans.  The seal fee for one dome on a slab is $600.   In Florida the highest required wind speed a building is to meet is 180 mph; as a result, the Florida licensed engineer has performed structural calculations on Ai’s largest size dome at 180 mph winds, exposure D which can also be emailed to the building official along with an Equivalency Report or an Engineering Statement which states: “The panel composition of the geodesic dome buildings are certified by me as being designed in accordance with and conform to the intent of 2015 International Building Code, 2014 Florida Building Code 5th Edition, 2016 California Building Code, Residential construction per section R104.11 that allows for alternative materials and methods of construction.  The American Ingenuity dome meets the intent of the minimum steel provisions of ACI 318-11 section 10.5 and provides a comparable or higher level of quality, strength, effectiveness, fire resistance, durability and safety. The inherent strength of the geodesic dome configuration creates a minimalistic combination of materials that is less than the more common building materials and configurations considered by the building codes. This concrete style of dome has been successfully installed in Florida, California and many states throughout the United States. Georgia Pacific’s DensArmor Plus High Performance Interior ½” Gypsum drywall/wallboard is used as the interior face of the panels which meets the thermal barrier requirements of R316.4 as shown by third party testing.”

American Ingenuity (Ai) has been in business for over 40 years and has shipped dome building kits to 47 U.S. states and 15 foreign countries (Caribbean, Thailand, Australia, etc.) from its Rockledge Florida factory.  Ai designs geodesic dome building plans for ten size kits with an AutoCAD program for residential homes or businesses.  After the kit is assembled and finished with local materials (doors, windows, bathroom fixtures, kitchen cabinets, etc.) results in homes of 172 sq.ft. to almost 3,000 sq.ft.  Up to four domes can be linked together to make larger complexes.  The exterior shell building kits with building plans range in price from $20,000 to $67,000. This pricing does not include shipping or engineer seal on the building plans or pricing for custom foundation plans..

The prefabricated panels  for the dome kit includes exterior 3/4″ concrete reinforced with galvanized steel mesh/fibers, center core of nontoxic, rigid, 7″ Expanded Polystyrene (EPS) R-28 insulation (not Styrofoam) with half-inch Georgia Pacific DensArmor Plus drywall adhered to the underside of the EPS with drywall adhesive. Onsite, the kit is assembled by lifting the panels into place with some type of hoisting mechanism, overlapping and locking the galvanized steel mesh in the seam areas.  The seams, entryways and dormers are then concreted onsite with fiber concrete (seam concrete averages 2″ thick). The concrete/steel/eps/ and drywall contain no food source for mold growth and are noncombustible.  Since our panels come pre-concreted, only the seam areas between the panels, along with and the entryways and dormers are concreted on site; resulting in reduced on site labor costs versus building a conventional house with separate materials to build the vertical walls and install roof trusses, plywood, tarpaper, shingles, insulation and drywall.

Ai designs the building plans and manufactures the dome building kit. Ai is not a construction company.   A new and improved Assembly Manual is shipped with each kit.   Ai’s clients hire a contractor to build their dome home, with the remaining clients being self-build or an Owner Builder.  If not owner building the dome, research and find a green contractor and pay him cost plus.  The contractor can hire the Independent Assembly Consultant  to supervise the concrete workers & laborers getting the dome shell assembled up to the first layer of concrete in the seams and on the entryways and dormers.  By doing this, the home owner does not need to be concerned about hiring a contractor to assemble the dome shell that has never completed a kit assembly and the contractor does not have to be worried about learning to assemble the shell….the Consultant takes care of that concern. Once the shell is assembled (with the first layer of concrete in the seams and on the entryways and dormers), the Consultant leaves and home owner or the contractor hires a finish stucco crew to apply the second layer of concrete to the seams/entryways/dormers.  The home owner or their contractor hires the subs (plumbers, electricians, framers, cabinet men, painters, etc.) to prime and paint the exterior, finish the interior and install the locally purchased doors and windows, etc.  Please review the Kit Assembly for assembly steps.

To support the panels during kit assembly, a temporary wooden rib system is installed.  The buyer can purchase precut, drilled, painted 2×4’s from Ai.  The 2×4’s are bolted to steel hubs to make a wooden geodesic skeleton. Once all the seams are concreted and the entryways and dormers are concreted, the dome is self-supporting and the wooden rib system is removed with the steel hubs being returned to Ai for a refund on the hub deposit. Most of the wood can be recycled as interior framing.

The cost to build one of Ai dome kits runs about the same to build per square foot as a traditional home (not built within a housing development)  but has insulation comparable to 10” of fiberglass and has super-strength and all the advantages described above.  A traditional home would require 2×10 frame construction with 10” of fiberglass batting to come close to our dome….but it would have wood interrupting the insulation.

 Ai’s manufacturing costs here in Florida are well below the national average, which offsets any long-distance shipping expenses. We can actually manufacture a kit here in Florida and ship it to the western states and northern states or internationally cheaper than we could manufacture there.  Having our manufacturing plant located in Florida is advantageous for shipping since more is shipped in than out of the state, leaving many trucks headed out empty.  Ai utilizes independent trucking agencies. We contract to have a truck carry the building kit outside Florida for approximately $2.70 to $2.90 per mile per semi-truck from our plant in Rockledge, Florida.   These trucking costs are less than we could do with our own trucks because if we used our own trucks, they would deliver the kit and return to Ai’s factory empty.  One each 27’ thru 48’ kits with standard 4’ riser and standard R28 insulation fit on one semi-truck. Multiple smaller size kits can fit on one truck. Internationally the kits are shipped in containers.  One 34’ kit (when finished with local materials) results in two bedroom/two bath size home fits in one 40’ high cube container.

 

The American Ingenuity Dome Kits
are DIY Prefab Dome Homes for Owner Builders or for a Contractor

The prefab dome kit can be a Do It Yourself Project with the owner builder utilizing family and friends or hiring his own workers for kit assembly.  Or the home owner can hire a builder who hires the independent Kit Assembly Specialist who travels world-wide to supervise your kit assembly and the application of the first layer of fiber concrete into the panel seams and onto the entryways and dormers. Then either your workers or your builder’s workers complete the second layer of concrete in the seams & on the entryways and dormers. For interior finishing complete yourself or hire local subcontractors to complete the plumbing, electrical, framing, window/door installation, wall board finishing, kitchen cabinetry, bathroom fixtures, etc.  To view pictures of prefab concrete panel assembly, click on Dome Kit Assembly.

American Ingenuity’s (Ai’s)dome kit is affordable, strong and can be assembled by Do It Yourself individuals because the kit is engineered as a system of pre-finished prefabricated component panels. Each panel is cut at a computer-generated angle so that it fits flush with the adjacent panel. The edges are precisely beveled at the seams where steel and concrete will unite to complete the structure. All panel materials are noncombustible and contain no food source for mold growth.

Building an Ai dome from prefab concrete panels makes home construction easier than stick built construction and results in the dome exterior having a 225 mph wind and F4 tornado guarantee. The process of stacking the panels, overlapping/locking the steel mesh of adjacent panels and filling the seams with special fiber concrete, produces the structural components of the home, the finished concrete surface, installs the insulation and all the dome shell 1/2″ drywall.

This advanced building system makes it easier for an owner builder to construct an American Ingenuity dome than a conventional house or a wooden dome. No exterior walls, no roof trusses, no sheathing, tar paper, or shingles, no soffit, exterior trim, insulation or siding to install and no interior shell drywall to install.  During the dome kit assembly, owner builders or builders can email pictures of the kit assembly. At no cost to you, Ai will review the pictures and give feedback about rebar and cable installation, etc.  Due to large size of panels in 45′ and 48′ domes, considering hiring the consultant to assist in your assembly.

Nomenclature Diagram

The building plans contain blueprints for the installation of the foundation and installation and location for each panel. Within the plans is a nomenclature blueprint that shows lettering and numbering for each panel. An example of a nomenclature blueprint is above.

An Expanded Assembly Manual is now available with each dome kit order that explains step by step the panel assembly. (Once a deposit with signed order is received, the manual can be shipped). In the blueprints and Manual is the recipe for the concrete. Ai wants the concrete mixed on site to have the same properties as the concrete that is applied at our factory; as a result the same two liquid admixtures and fibers are shipped with each kit. In the manual is a list of tools and materials to have on site. To view a list, click on Materials and scroll down the page to view the list.

American Ingenuity’s prefabricated component panel consists of:

1.   7″ thick, rigid, nontoxic E.P.S. Insulation (not Styrofoam): The E.P.S. Ai utilizes is a closed cell with a 1 lb. per cubic foot density.  Seven inches of sturdy, rigid R-28 expanded polystyrene foam insulation forms the core of each component panel and is:

  •  Permanent
  • Chemically/thermally stable
  • Resistant to mildew and mold
  • Provides no nutritive value to animals/plants/microorganisms
  • Non-irritating to the skin
  • The insulation will not rot, shrink, absorb moisture, compact, or deteriorate due to age or the weather.
  • No CFC, no HBCD (hexabromocyclododecane), no TCPP (1-chloro-2-propyl) phosphate, no Chlorofluorocarbon (CFC) and no Formaldehyde

2.     Concrete: the concrete in your dome out performs other exteriors due to our specially developed formula. Because of this exceptional composition, it actually gains strength over the years. The special concrete formulation of fibers and admixtures improve concrete characteristics.

3.     Galvanized Steel: Galvanized steel wire mesh is encased in the concrete of each panel. As your dome is assembled the mesh of each panel overlaps and is locked to the mesh of  adjacent panels with C rings commonly called hog rings – resulting in your home being completely wrapped by steel mesh.

4.   Half inch (½” ) Georgia Pacific DensArmor Drywall: The DensArmor is not conventional sheet rock. Conventional sheet rock consists of conventional gypsum and paper backing. The paper backing can be a food source for mold growth. Sheet rock when it gets wet crumbles and molds. The DensArmor gypsum when it gets wet does not crumble due to fiberglass reinforced core. It has fiberglass backing on both sides. After the DensArmor dries out it goes back to its original firmness and consistency per the manufacturer.

Concrete Home
Dome Exterior Has No Wood To Burn or To Rot or For Termites To Eat
No Shingles or Roof to blow off in high winds

To support the panels during dome kit assembly, a temporary wooden rib system is installed. Once all the seams are concreted and the entryways and dormers are concreted, the dome is self supporting and the wooden rib system is removed. Most of the wood can be recycled as interior framing.

 

45' dome - assembly of third row of panels

45′ dome – assembly of third row of panels

In this view of dome kit being assembled a side view of a component panel can be seen. The panel exterior is 3/4″ concrete reinforced with galvanized steel mesh. After the mesh is overlapped and locked between panels, special fiber concrete mixed on site is hand troweled in the seam areas in two applications — bonding agent is applied between the two layers. The seam areas are about 3″ deep by 5″ wide with average of 2″ thick concrete.  In this picture you see the first scratch coat applied to the exterior of the entryway panels and first layer of concrete in some of the seams between the panels.

Steps for American Ingenuity Concrete Building Kit Assembly:

  • Foundation installed. Standard foundation is monolithic slab; however Ai can design basement plans, pilings or columns, stem wall, etc.
  • Depending on size dome two to five workers are needed. Some with concrete experience.
  • Installing the first row of panels which are the 4’ vertical riser panels, base panels of the entryways and any first floor door dormer base panels
  • Erecting a temporary wooden rib system to support the triangle and riser panels during assembly using your locally cut, drilled and painted 2×4’s bolted to steel hubs borrowed from Ai.
  • Placing the panel’s one row at time using a hoisting mechanism (man lift) on to the rib system.
  • overlapping steel mesh from adjacent panels, locking mesh with C rings and pliers and depressing the steel mesh in the seam
  • mixing concrete with mortar mixer following concrete recipe in the manual (Portland Cement Type III, masonry or stucco sand, fibers, liquid admixtures)
  • installing cables per blueprints
  • installing rebar around back of entryway panels, back of first floor door dormer panels, top of entryway panels & around first floor window dormer panels per building plans
  • form up and install beams or troughs around lip edge of entryway panels, first & second floor door dormer panels, channels in top of the entryways
  • Concreting the seams between the panels (5″ wide and 3″ deep) with two separate layers of concrete using a bonding agent between the layers; and watering down all cured concrete before applying bonding agent or new concrete. Seam areas average 2” thick concrete.
  • Concreting the entryways, window dormers, door dormers, cupola and link with two layers of concrete. Sponge float finish the final layer of concrete to blend seam concrete to the panel concrete.
  • Framing in the entryways and dormers and installing your locally purchased exterior doors and windows.
  • Removing the temporary wooden rib system. Return the steel hubs to receive a full deposit refund if returned during five month rental period and if all hubs are intact.
  • Wash efflorescence off concrete, prime, paint the exterior concrete per waterproofing instructions in Assembly Manual.

Onsite concrete is only applied in the seam areas between the panels and on the entryways, dormers (or possible link or cupola). Concrete is not applied over the pre-concreted component panels. The interior shell drywall can be finished similar to conventional sheet rock with adhesive fiberlass and joint compound. To blend the seams joint compound can be skip troweled over the drywall before priming and painting.

If I am not ready to assemble my dome immediately, can the kit be stored outside? Yes, however if you expect to have your kit outside for more than two to three months, request that the E.P.S. edges be painted. On site if you need longer than 2-3 months prior to assembly, then on site the EPS edges can be painted again. (some boxed items & wooden 2×4 ribs if ordered should be stored inside.) The dome kit should not sit outside in the winter as freezing can harm the drywall.   Please call us for details at 321-639-8777 – Monday – Friday 9-5 eastern time.

The following information covers Tiny Home Kit reg & sale pricing w’ specs.  Ai has added two new tiny home sizes to its Tiny Home assortment – 15′ and 18′!   These Tiny Dome Home Kits are constructed using Ai’s superior prefabricated insulated concrete panel system.  Consider them for Special Hideaway, vacation cabin, mother’s home, guest house, hunting cabin, glambing, tiny home, micro home, cottages for resort, rental units for veterans or a starter home.  The Ai dome is much stronger, has noncombustible materials in its wall panels, fire resistant concrete exterior & more insulated than a framed house, concrete block house, log cabin, tent or yurt.  Also all the panel materials contain no food source for mold growth.

Additional dome kits can be added later and linked to the first dome built on your site.  If you believe you want to add on later, discuss with our design team and a link can be installed on the first dome where a second dome can be connected later.

Tiny Dome Home Kits when assembled and finished can result in 172 sq.ft. to 1,278 sq.ft.  The domes can be one story. Dome sizes are measured by feet in diameter with the 15′, 18′, and 22′ kits having a first floor with optional attic/loft.  The 27′, 30′ & 34′ can have a second floor installed if you so desire. The 27′  dome second floor panels are large enough for a window dormer to accept fire egress size window.  The 34′ second floor window dormer is too small to accept a fire egress window so door dormer panels are installed above a first floor standard entryway to accept a fire egress size casement window.  With a 2nd floor egress window installed this allows the 27′ & 34′ domes second floor to contain a bedroom; resulting in the 27’ & 34’ domes being two bedroom/two bath size homes. The 30′ dome second floor panels are not large enough for a window dormer so no bedroom can be designed – use the 30′ second floor for storage, office, craft area, additional bathroom, rec room.  To view stock plans for the 15′ and 18′ along with plans for the other Tiny Domes, click on Tiny Home Plans.

As far as Tiny Homes meeting minimum size house requirements – in some areas,  groups are petitioning their county or their city elected government officials to allow them to have Tiny Home Communities (called pocket neighborhoods) where the minimum house size can be below state code. The City of Rockledge, Florida agreed that a group whose face book page is called Rockledge Tiny House Community can purchase property and build Tiny Homes from 172 sq. ft up to 1000 sq ft. in their city.   Normally in Florida the minimum new house size requirement is 500 sq.ft. or 800 sq.ft. or 1,000 sq.ft.  So congratulations to the City of Rockledge Tiny House Group for its victory in changing minimum size house requirements in their city to as small as 172 sq.ft..

Please check local codes to see how Tiny Homes can be built for cottages in a resort or for rental units to rent out to migrant workers, veterans and individuals wanting to live in strong (225 mph & F4 tornado warranty), energy efficient houses whose exterior concrete is fire resistant.  To view comparison of concrete dome kit to log cabin, click on log cabin.  To view info on Ai dome and tree impact & snow load, click on Tree.   To view complete summary of advantages of Ai dome, click on Summary.

The kit can be purchased with 7″ EPS, 1/2″ Drywall & exterior 3/4″ concrete reinforced with galvanized steel mesh/fibers.  And only the 15′ & 18′ kits can be purchased with 3 1/2″ EPS, no drywall and no reinforced concrete.  The larger kits cannot be purchased with only 3 1/2″ EPS because this size insulation makes the larger panels to flexible causing EPS breakage.
  2. 22’ & 27’ Kits  consists of all the triangle prefab panels and standard 4’ riser prefab component panels for the dome shell and panels for one entryway.  5 foot tall risers can be ordered instead of the standard four foot tall risers. Your floor plan selection determines how many more entryways and dormers are in your kit.
  3. 30’ & 34’ Kits consist of all the triangle prefab panels and standard 4’ risers prefab component panels for the dome shell and panels for one entryway. To increase first floor ceiling height where a second floor is above, on site install a one foot tall or two foot tall perimeter wall to increase the height to 8’6″ or 9’6″.  Your floor plan selection determines how many more entryways and dormers are in your kit.

Each triangle and riser prefab component panel consists of exterior ¾” fiber concrete reinforced with galvanized steel mesh, center core of 7″ R-28 expanded polystyrene (EPS) insulation with interior special moisture resistant, mold resistant 1/2″ gypsum drywall from Georgia Pacific called DensArmor Plus. During kit assembly it can rain. Water does not harm this special DensArmor drywall. The 15′ & 18′ kits can be purchased with 3 1/2″ R14 EPS insulation and no drywall. 

The dome kit’s prefab concrete panels can be assembled by owner builders and is a true Do It Yourself kit. All the panels come marked with numbers and letters to match the building plans and the Assembly Manual. On site,  fiber concrete is troweled into seams between the panels and on the entryways or dormers. Seam concrete average thickness averages two inches. An Independent Kit Assembly Consultant can be hired to supervise your workers or your Builder’s workers during kit assembly.

If you do not see a stock plan to fit your desires, Ai can modify or customize a plan from your sketches and descriptions.  Each Set of Building Plans includes the floor plan layout(s) and consists of 13 – 17 blueprints depending on type of entryways and dormers in your kit.  To view sale pricing on all the stock plans and the dome building kit for each plan, click on Stock Plans & Kit Sale Prices.

Ai’s philosophy is that each Buyer pays for only what they need.  Ai does not burden the price of the building kit with plan’s pricing, engineer seal cost or energy report cost. Building plans are purchased three months to -1 1/2 years prior to kit shipment.  About 50% of the building departments require engineer sealed plans and an energy report to issue a permit. As a result, each customer pays for their plans separately from the building kit and pays for a seal and energy report only if their building department requires them.

Building Departments vary by state as to what they require to issue a new home building permit.  If you give Ai your parcel ID number & building department name, we will call and email info to them and find out what is required for them to issue a permit.  Will they require the building plans to be sealed and stamped by an engineer licensed for your state? Will they require an Energy Report?  If required these items can be purchased from American Ingenuity. To learn more about building permit, click on permit.

The standard foundation under Ai’s domes is a concrete slab. Other types of foundations; i.e. basements, stem wall, pilings, require the hiring of an engineer. Call for engineer pricing. Each buyer tells Ai the type foundation they want designed.  The foundation type is determined by property terrain, building department requirements and requirements from a soil report.

Plans may be purchased with a credit card, check or money order. Stock plans utilize a concrete slab foundation and are delivered within 2-4 weeks, Allow at least 5 modified plans and 8-10-12 weeks for custom plans.

How does the American Ingenuity dome withstand tree impact & snow load versus truss roof house?  Very well based on three actual dome owner’s experiences.  To view info about Aidome withstanding Hurricane Irma’s 200 mph winds and suffering no damage please click on Hurricane Irma

Exterior basement snow 0272

For those of you who are researching what type house to build in a forested area, please consider the advantages of an American Ingenuity concrete dome versus a log home with a truss roof or a conventional house with a truss roof.

One of American Ingenuity’s perspective kit buyers emailed this question: “When I was living in the deep woods and any kind of wind storm or even a bad ice storm came up it was a major concern/fear of a large tree branch hitting the house.  How does the Ai steel reinforced concrete dome roof compare to truss roof for tree impact & heavy snow load?”    Based on two actual Ai dome home examples, the Ai concrete roof is so strong it can resist 30″ in diameter tree impact and the weight of several feet of snow. 

Homes built in a forested environment run the risk of having a tree fall on the roof or if in a cold climate a possible ice storm can cause ice loaded tree branches to fall on the roof. The steel reinforced concrete roof in an American Ingenuity dome is resistant to tree impact damage. However a wood truss roof is likely to be damaged from a tree branch or tree falling on the roof.

The strength of the Ai dome is evident in this example of a tree falling on the American Ingenuity dome. There was no damage to the Brack’s 48′ American Ingenuity dome after winds in excess of 75 mph hit North Carolina in July of 1996. The real test came when a 115′ high, 30″ in diameter hickory tree was blown over and fell on their dome. The impact broke a 10″ diameter branch off the tree. The tree slid off the dome and landed on a deck post driving it and it’s 16″ square concrete footer 6″ further into the ground. The insurance agent who inspected the damage to the deck conveyed his amazement about the dome’s strength with this comment, “If that had been a frame house the tree would have ended up in the basement!”

The American Ingenuity dome could handle the tree’s impact due to the triangle panel shape being the strongest shape among all shapes and because the steel mesh from panel to panel is overlapped, locked & covered with fiber concrete. As a result the continuous panel mesh transfers the stress throughout the dome. In a conventional house the stress is confined to one area resulting in the tree probably damaging the roof or coming through the roof.

Hurricane Irma winds caused tree to uproot and fall on Aidome

The following two photos are of 40′ Aidome – dome had no damage just dent in a dormer 

Ai has heard from one of its dome owners whose steel reinforced concrete dome went through a tree impact caused by Hurricane Irma. The dome suffered no damage  – only a minor dent to a dormer.  This dome home was built in 2000 and is a 40’ dome linked to a 27’ garage dome located in Seminole County – central Florida.  Per the Orlando Sentinel  that area had 74 mph wind gusts with 50 mph sustained winds from Irma.  The following quote was emailed to Ai:  “I thought I’d send you this shot of a tree that landed on the dome during hurricane Irma.  My girlfriend was actually standing inside the doorway (inside the dome) when the tree hit and we both heard and felt the thud.  The tree is a Red Maple about 50’ tall. It uprooted from the ground and came to rest as you see in the photo.  It has a split trunk with a base dimension of 30” x 26”.  The two main trunks beyond the split are about 13” and  15” in diameter.  Once all of the smaller tree limbs were removed it was clear that the dome shell suffered no damage other than cosmetic paint scuffing and a minor dent in the edge of the dormer rim.  (fixable with Bondo or patching cement).  No cracks or other damage have been observed inside or out from the tree impact.  This is a testament to the strength of the dome!  I’ve also attached a shot of the tree with it’s branches removed so you get a clearer view of the tree itself without all the leaves and vines.  I’m still enjoying the dome living life after 17 years here now.”

More about heavy snow loads: Mr. and Mrs. Carroll visited Robens and Tom Napolitan’s dome. Robens was enthusiastic, but Tom was not. Tom explained to the Carroll’s, “Its all HER idea, I didn’t want a dome.” Mary Carroll phoned the Napolitans during a cold spell where they experienced heavy snow fall. Mrs. Carroll said you couldn’t keep Tom quiet this time. He had nothing but wonderful things to say about the dome and had completely turned around about the wonders of living in an American Ingenuity dome…..“ROOFS HAD COLLAPSED in their area under several feet of snow, but NOT HIS DOME!” Tom’s turnaround sold Mary and her husband on an Ai dome.

How does the Ai prefab home dome stand up to high winds, ice storms, several feet of snow & forest fire?  American Ingenuity performed a load test on our largest 48′ triangle.  The triangle shaped component panel withstood 170 lbs. per sq. ft.  load.  A 120-mph wind will exert a pressure of 30 lbs. per sq. ft. on a vertical wall and a snow load exceeding 90 lbs. per sq. ft. is rare. Typically snow loads are 20 to 50 lbs. to 90 lbs. per sq.ft.  Engineers have assisted Ai’s design team to design the dome to withstand 90 lbs per sq.ft. snow load.  Recently dome building plans were designed for Colorado at 90 lb snow load and 110 mph wind speed  which were engineer sealed for Colorado.

The strength of the concrete Ai dome makes it resistant against tree impact, heavy snows and fires making it ideal to build for a vacation home or a retirement home where the home is not occupied year round. If the dome home is built in a cold climate, there will be times when the family may want to live in a warmer climate during the winter. As a result the home owner wants to build as resistant a home they can against heavy snow load or tree impact or fire.   For info about fire and Ai dome, click on  forest fire.

Greater Exterior Wall & Roof Strength – the concrete American Ingenuity dome exterior comes with 225 mph wind and F4 tornado warranty. An Ai dome went thru a tornado & Hurricane Andrew at the same time with no structural damage. An Ai dome went through Hurricane Katrina with no structural damage.

When deciding which building kit to purchase, please compare apples to apples which means please compare the contents of the log home kit or the traditional home kit vs the contents of the Ai dome kit and compare kit costs. The Ai panelized system has proven to save our client’s labor time, as well as a reduction in material waste and material costs vs a log home kit while having numerous advantages over log cabin home —- fire resistant concrete exterior, tree impact resistance, able to handle heavy snow load.  For log home kit comparison to the Ai dome, click on Log Cabin Home.

The process of overlapping/locking the steel mesh of American Ingenuity’s prefabricated panels to adjacent panels and filling the seams with special fiber concrete produces 1) the structural components of the home; 2) the finished concrete exterior surface; 3)all the shell R28 insulation is installed; and 4) all the dome shell 1/2″ drywall is installed. There is no need for material costs and labor costs to install roofing plywood, tar paper, shingles or interior attic & wall insulation and shell drywall (or wood panels).  To view photos of Kit Assembly, click on Assembly.

The American Ingenuity dome is very energy efficient because it has 30% less surface area than a conventional house and has R28 EPS insulation that is not interrupted by wood…expect heating and cooling bills to be 50% to 60% than your neighbors.  Ai’s standard 7″ Expanded polystyrene insulation is comparable to 10″ of fiber glass batting.  If desired the Aidome insulation can be upgraded to 9″ thick expanded polystyrene (EPS) resulting in R36. In conventional houses the vertical walls have one R value and the roof has another R value requirement.  In the Aidome because all the panels which make up the walls and roof have the same R value, this means the Aidome will pass an Energy Report.  If your floor plan has four or five entryways with the glass maxed out, to pass an Energy Report the glass may need to be triple panned instead of the typical double pane glass.

Here are some quotes about Ai dome and energy efficiency:

As far as functioning in cold, snowy environment, American Ingenuity domes have been built in Canada, one built at 7,500 feet elevation in Utah and Aidomes have been built in all cold states in the USA except for New Hampshire, Rhode Island and North Dakota.

One of our customers in Pennsylvania built a 40′ dome on full basement. This is quote from them: ““We live in the mountains of PA. The winters up here can be brutal. Our Ai Dome is a 40ft with Link on a 9″ thick livable basement. {Den, Office/Computer room, Kitchenette} The entire interior, to include the mechanical room, is heated and cooled by a GeoThermal, Water furnace, Radiant floor system. Our zone controllers are set on 74 degrees winter and summer. Our sole power source, at present, is the grid. Our costs per month range from $99 to a high of $120. We were amazed that our cost now are less than when we lived in a 14 by 73 ft mobile home while building the Dome. Our decision to build an American Ingenuity Dome home was the best decision we have ever made.” To view pictures of their dome and other info, click on Charles Dome.

A picture of the dome at 7,500 feet elevation in Utah showing snow is one of the flashing pictures on our home page. The dome is off the grid and has increased EPS insulation from our standard 7″ R28 to 9″ or R36. Quote from the Utah dome owners: “Our house and solar electric system have met and exceeded all of our expectations. Our home is warm and spacious. Even with nighttime temperatures below zero, a fire in the masonry heater in the evening and a full day of sun warms the house to 70 degrees F. Our average summertime power consumption is between 150 and 200 kWh/month for 2700 square feet of living space. Wintertime consumption is somewhat higher. For comparison, our average pre-solar usage was near 600 kWh/month in our prior 2000 square foot suburban home.”  To view pictures and other info about the dome at 7,500 feet elevation, click on Collar Domes.

The Aidomes are even more energy efficient when heating is required instead of cooling. When cooling, kilowatts have to be used to overcome heat from clothes dryer, dishwasher, sun light, etc. When heating those heat sources are used.  Ai’s 3,700 sq.ft. office domes can be cooled for less than $55 a  month in the hot Florida summer months.  A Florida 1,200 sq.ft. 34′ dome can be cooled for less than $22 a month in the hot Florida summer months.

 

 

Ai received the following question about the fire resistance details for an American Ingenuity concrete dome versus a Monolithic concrete dome.  The question from Greg Legg is in regards to the YouTube Video posted below about a fire and concrete domes.  “I’m looking at the differences between your domes and the monolithic dome in the video about a fast moving fire and wondering how important it is to water down the exterior if a fire is approaching. In the video the owner mentions that he was surprised the pvc exterior wasn’t damaged during the fire. Not sure what he meant by pvc exterior but made me wonder.

A house roof on fire and smoke.

I live in an area where the only water source is water wells using an electric pumps for pressure. During fires it’s very easy to lose power from downed lines. If that was to happen there is no way I could hose down the exterior of the house. How would your exterior be any different in this situation?” Greg Legg

The American Ingenuity (Ai) dome is designed to be as safe and fireproof as possible, the dome exterior is entirely noncombustible concrete. The Ai dome exterior is fire resistant concrete reinforced with galvanized steel mesh that does not require watering down as the homeowner did for the PVC covering on the Monolithic Dome. 

On site during the Ai dome panel assembly, the exterior seam areas between the prefab concreted panels consist of overlapped locked steel mesh filled with fiber concrete. The Ai dome shell is built by installing Ai’s prefabricated concreted panels onto a temporary wooden rib system.  After all the seam areas, entryways and dormers are concreted, the dome is self supporting and the temporary wooden system is removed.  The exterior concrete is primed and painted. There is no wood in or on the Ai dome shell to burn or to interrupt the insulation. There are no shingles to burn.The exterior concrete on the American Ingenuity Dome has no exposed PVC membrane or exterior material that needs to be watered down.

Monolithic Dome Assembly per their website:  In the monolithic dome assembly an Air Form is inflated, polyurethane foam is applied to the interior surface of the Airform, steel reinforcing rebar is attached to the foam using a specially engineered layout of hoop (horizontal) and vertical steel rebar and then Shotcrete – a special spray mix of concrete – is applied to the interior surface of the dome. The steel rebar is embedded in the concrete and then about three inches of shotcrete is applied.  This method results in an exposed exterior PVC membrane or exterior material which was watered down in the dome video.

All the panels in the American Ingenuity dome kit come to your job site premarked with numbers and letters to match the Nomenclature blueprint in the Building Plans.  An Assembly Manual is shipped with each Ai dome kit.  The kit is assembled by the owner builder or the owner hires a builder.  If desired a Kit Assembly Consultant can be hired to supervise the workers during kit assembly.  The process of stacking the panels, overlapping/locking the steel mesh of adjacent panels and filling the seams with special fiber concrete, produces the structural components of the home, the finished concrete surface, installs the R28 insulation and all the dome shell 1/2″ drywall.

What are the American Ingenuity triangular and rectangular shaped prefab panels made from? Center core of 7″ Expanded Polystyrene R-28 Insulation (not Styrofoam!), exterior is ¾” thick concrete reinforced with galvanized steel mesh with interior of 1/2″ Georgia-Pacific DensArmor Plus High-Performance gypsum drywall board (which is moisture resistant, mold resistant gypsum and noncombustible).

After the mesh is overlapped and locked between panels, special fiber concrete mixed on site is hand trowelled in the seam areas in two applications — bonding agent is applied between the two layers. The seam areas are about 3″ deep by 5″ wide with average of 2″ thick concrete.

withstood Two Category Five Hurricanes with no damage

 

An Aidome owner in St Croix, US Virgin Islands, has emailed, called and sent pictures of their 34’ Aidome with 1,100 sq.ft. – two bedrooms & two baths.  Liz wrote: “I live in an Aidome on St Croix, USVI and in September was hit by not one, but 2 horrific hurricanes, Irma and Maria.  Let me tell you I was so happy to be in a dome with no roof to lift.  Maria hit St Croix with 185 MPH winds!!   The only damage at all was to our solar whole house fan on top of house.” 
She also called and told us: “Within 12 days we went through two category 5 hurricanes (Irma and Maria) where the area was destroyed.  The hurricanes took out our hospitals, airports and schools.  The Aidome stood strong and suffered no damage with only the solar fan broken.   Also she said they had mini tornadoes which blew their storage sheds apart.   Her husband is a Purple Heart Vietnam War Veteran who said the area looked like a war zone.    To view a photo gallery of photos on this dome, click on St Croix

34′ Aidome in British Virgin Islands Built in 2007 
Withstood  Hurricane Irma’s 200 mph winds with no damage. 

 

 The Aidome’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 90 lb. snow loads. This wind warranty does not apply to a  cupola, link, exterior doors, windows or exterior framed wall areas.    In almost 40 years, Ai domes have survived all major USA hurricanes  (Irma, Andrew & Katrina),  tornadoes, a Hawaiian earthquake, a 30″ in diameter hickory tree impact with no structural damage and several feet of snow.  To read a recap of the Ai dome and acts of nature, view  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.

Prefabricated home dome kits 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, American Ingenuity’s 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 opportunity to build one of the most Eco Friendly homes available today. The Ai dome was Green before Green became a word to describe energy efficient homes that do not waste our natural resources.  All the prefab panel materials: fiber concrete, galvanized steel, expanded polystyrene insulation and 1/2″ Georgia Pacific DensArmor drywall are noncombustible and contain no food source for mold growth.

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.

What Does The Prefab Home Dome Kit and Component Panel Consist Of?

The component panels consist of a center core of 7″ of rigid noncombustible expanded polystyrene (EPS)  insulation NOT styrofoam. On the exterior of the EPS is 3/4″ fiber concrete reinforced with galvanized steel mesh. On the interior of the EPS is noncombustible 1/2″ Georgia Pacific DensArmor mold resistant and water resistant gypsum drywall.   DensArmor Plus Interior Panel is a highly mold-resistant, interior gypsum wallboard. By featuring fiberglass mats on both the front and the back, they offer the best in interior moisture protection currently available.  During kit assembly it could rain.  After the drywall is allowed to dry it goes back to its original consistency.  The wallboard is not conventional sheet rock that will crumble and mold when it gets wet. The exterior seam areas between the panels, once filled with on-site fiber concrete are about 3″ deep by 5″ wide with the concrete averaging two inches in thickness. Engineers tell us the steel reinforced concreted seams act like steel beams.  To learn about the prefabricated panel’s composition, click on Composition.

Following is a thesis on geodesic domes written in 2010 by Taralyn Fender who teaches math at a University.  The title of her thesis: Are Geodesic Dome Homes More Energy Efficient and Wind Resistant Because They Resemble a Hemisphere?

The Conclusion of her thesis: Simulations and observations from hurricane disaster scenes do suggest that the geodesic dome structures suffer far less destruction than rectilinear structures. The hypothesis is that geodesic domes are more energy efficient and more wind resistant because they more closely resemble a hemisphere.
