Knock $4,000 off Your Taxes by Going Solar


Save even more by adding state incentives to those in the new federal energy bill, the first in 20 years




In the new energy law, the U.S. Congress lavished tax breaks on its usual fossil-fuel favorites—there’s $1.6 billion in tax credits for new coal technology, $1 billion for gas distribution lines, another $1 billion for oil and gas exploration costs, $400 million for oil refineries, and so on.

But the solar energy industry is betting that its comparatively tiny share of the energy bill spoils will be enough to jump-start the industry.

The cost of the solar tax breaks to the U.S. Treasury—less than $52 million out of a $14.5 billion energy package—may seem trifling. But the handout shows that Washington supports solar, and that should encourage more states to offer breaks too, solar supporters say.


“For anybody who has ever considered installing a solar system, Washington is telling you to do it now,” says Rhone Resch, president of the Solar Energy Industries Association in Washington, D.C. That’s good news for solar equipment manufacturers like General Electric and Evergreen Solar.


Claiming the credit


The law both increases tax credits for commercial solar installations and offers individual homeowners a credit for the first time in 20 years. (An earlier personal-use solar credit was in effect from 1979 to 1985.)

Companies such as FedEx and Johnson & Johnson that have already installed solar systems on some properties, and have made a commitment toward adding more, are likely to pick up the pace, predicts Resch. “The federal incentives by themselves will not create a market for solar energy, but when combined with state incentives, you reach the economic tipping point to make it work,” he adds.


Homeowners get a more limited credit. They can put in a photovoltaic system (roof panels that take in energy from the sun and turn it into electricity) and/or a solar-powered hot water system (for hot water heaters, radiant floors or radiators), and get a federal tax credit worth 30% of the systems’ cost, up to a credit of $2,000 per system. There are a couple of catches: The heating system can’t be for a pool or hot tub, and the federal credit applies to the net system cost after any state incentives.


The good part is that this new federal break is a credit—not a deduction—meaning it reduces your tax bill directly, dollar for dollar. So, if you install both eligible solar systems in your house, you can knock $4,000 off your federal tax bill. And if you have more credit than you owe in tax, you can carry it over and use it to defray next year’s federal tax bill.


During Summer months the cooling can be done with the following:

  • Evaporator cooler blows cooled air through ducts that distribute through compartments
  • Rear Door side window vents allows cool air at night into the dome
  • Convection of hot air is drawn up to the center of the dome and out through a 8 inch vent at apex
  • A diverter valve in the summer routes all cold water through hydronic floor when using either hot or cold water to cool floor.
  • A rollup Insulated steel door can be lowered to cover the picture window during hot days

Solar Chill Humidity Vs Ambient Temperature

 American Ingenuity’s component panels for the 15′ – 48′ domes contains seven inch thick rigid Expanded Polystyrene (E.P.S.) insulation which has an R value of 28.  The seven inch thick insulation is comparable to eleven inch thick fiberglass batting. There is no wood in the American Ingenuity Dome shell to interrupt the insulation or to rot or to be eaten by termites or to burn. However, a temporary wooden rib system is utilized to support the panels during the dome assembly until all the seams between the panels and the entryways and dormers are concreted and then the system comes down.  The dome is self supporting. The exterior is steel reinforced concrete that is primed and painted.  Your locally purchased doors and windows are installed in pressure treated wood framed wall under the entryway and dormer panels.

1. What’s the benefit of insulating my home?

  • Insulation can help reduce the cost of your heating and cooling bills by preventing the flow of heat into your house in the summer time and reducing the flow of heat out of your home in the winter time. In short, you can save money.

2. What’s the most important thing to know about insulation?

  • Its “R-value.” The R-value of an insulation product gauges the resistance the insulation has to the flow of heat.The higher the R-value, the better the product will resist heat flow. R-values are standardized, so you can compare different brands and types of insulation, and still know their relative ability to resist heat flow.

We have all heard builders claim to build “R-13” or “R-21” walls with wood frame construction. The problem is that only the highest rated component in the wall – the insulation itself – performs at these stated R-values. A wood frame wall is made up of several components, not all of which have the same R-value. For instance, a 2×4 or 2×6 stud has an R-value of about R-5 or R-7. Every 16 inches or so, one of these components breaks the insulation layer and forms a “thermal bridge”, conducting heat through the walls at high rates in addition to being a major cause of mold in standard construction. Adding up the area of studs, plates, and headers, 12% to 16% of the total wall area is an R-5 or R-7 thermal bridge, all detracting from the stated R-value. In addition, batt insulation tends to sag over time and leave spaces without any insulation! How can those builders claim only the highest-component R-value? From a whole-wall perspective, framed walls operate at far lower R-values – sometimes only half of the advertised value.

American Ingenuity’s (Ai’s) prefab panel contains seven inch thick Expanded polystyrene (EPS) insulation which consists of a solid piece of  EPS that provides a continuous layer of insulation rated at R28. From a whole-wall perspective, an EPS wall actually lives up to the advertised R-values because thermal bridging is absent.

Thermal conduction is not the only mode of energy loss in a building. In fact, conduction often contributes less to energy losses in wood frame buildings than convection, which is not even measured by R-values.

Thermal Convection is heat transfer by movement of currents within fluids or gases. When considering energy performance of buildings, it’s the air moving between the inside and outside or “air infiltration”.  A common measurement is ‘Air Changes per Hour’ at a blower-door induced pressure differential of 50 Pascal (ACH50). US Energy Star standards for new homes require less than 4-7 ACH50. In comparison, Canadian R-2000 standards are 1.5 ACH50, and Swedish standards are 0.5 ACH50 or less.

  • In wood frame buildings convection can be felt as drafts and is usually the biggest source of energy loss. Air infiltration accounts for up to 40% of the energy losses of a wood framed structure. Energy escapes via conditioned air leaking through thousands of cracks, openings, and joints between all the “matchsticks” of the building shell. Major culprits include framing connections, wall, floor & roof intersections, shrinkage of wood and caulking, and poor installation of components and sealants. A typical new wood frame home has between 1.75 and 3 air changes per hour (ACH50) and after some years it’s often between 5 and 10 ACH50 as the wood shrinks and sealants deteriorate. Old wood frame homes commonly have 10 to 20 ACH50.
  • EPS walls & roofs are an effective air (and vapor) barrier because the concrete is solid without passages for air to leak, thus eliminating a major percentage of air infiltration. EPS buildings consistently get results of 0.5 to 2.5 ACH50 and less, largely depending on the installed roof type and sealing. Most air infiltration in an EPS home is through a conventional roof and around windows & doors, so pay attention to these areas. Adequate air exchange in very airtight buildings must be ensured, typically using mechanical ventilation. Mechanical ventilation can be combined with ‘heat/energy-recovery’ units and/or ground heat exchangers for additional savings where conditions & budgets allow it.

R-Value Table: Insulation Values For Selected Materials

Use the R-value table below to help you determine the R-value of your wall or ceiling assemblies. To obtain a wall or ceiling assembly R-value you must add the r-values of the individual components together.

This method ‘Wall Assembly R-Value” gives incorrect results for MASS walls such as the All Wall System.

Example of error, as defined by ORNL research papers.

When compared to a 6” R-20 framed Wood Wall a Foam Block (ICF) wall performed with a 9% better Energy Savings.

A wall built like All Wall performed with an 18% better Energy Savings. (9% over the Foam Block walls) because of the concrete being in direct contact with the interior.

July 12, 2018 Testimonial from an Aidome owner in Texas

I am glad for the use of such a secure dwelling.  I purchased my Aidome building kit in 1995 and have been in the safest structure I could hope for short of a Monolithic Poured Bunker.  My trip with Dome building did not start with Aidomes.

Instead it started years before I made my purchase, my Dome adventure started in the Military when I had so little money to pay my living expenses. Rent was fixed but the monthly cost of utilities could swing wildly depending on my location, roommates and the weather in my location.

I looked at this as a simple problem of supply and demand. Utilities were not a constant so it became my job to peg a way to limit the swings in my finances. Living without AC in the Coastal regions of the south was not fun but pick the right spot and the sea and surf could offer relief in the summer. In the winter a wood burning fire place required a lot of work but I had a known reserve and a way to control cost.

This sounds pretty simple and a way to limit the Grid’s impact on my lifestyle was needed. Except I could be transferred at a moments notice and all my reserves and plans would go out the door. Even an inconsiderate roommate could blow your budget and my credit rating. I once shared a place on a nice southern Island. It was heated by kerosene and this was one way to control cost. It takes planning and a bit of work to make it from one pay day to another using kerosene but with self-control and a willingness to sleep with a load of wool blankets you can save a lot of money. Unless you go on an operation and your roommate runs out of fuel and you come home to a large electric bill due to said roommate using the electric oven to heat the rent property.

A major expense slammed my check book when I returned home. At least the other roommate knew what to do and we convinced the third person that he needed to seek other quarters. This and other experiences over the years suggested there must be a better way.

Of course, the structure you live in is the base of your expense and another item is the location as well as the geographical plot. After years of roaming the world I returned home to a warm and dry area. Shade trees were not for me as the proof of my travels that weather itself can destroy trees, be it cold, drought or a fire all your plans could be changed by Mother Nature.

I knew a little about Buckminster Fuller and his many experiments. His inventios were based on geometry and the use of the geodesic dome as a lifestyle that controlled the cost of living be it private or commercial.

The geodesic dome was my choice for a well-built storm-resistant structure. And the search was on for what I hoped would be the last structure I would live in. Plans were found for a DIY dome. These were complete plans with information on how to cut the foam and what to do during assembly. The problem I saw was the labor-intensive construction and the piecemeal way of assembly. Given one bad storm in the middle of the assembly process and the dome could be gone with the wind.

With this knowledge I shifted to a design of a Monolithic Dome. I did find a company to build a Monolithic Dome and thought that was the way to go. Half way through the Monolithic Dome build I concluded the Company I had contracted for the build did not have an Engineering Staff and it was more time and trouble than I could control from 285 miles away. I did complete that dome and decided I needed a better design so back to the Geodesic Dome.

I contacted Aidomes and found a lot of information and help. Being careful I went to their Headquarters and liked what I saw. A model dome was on site and their factory was close too. The system would allow a contractor familiar with concrete construction to build a dome with the aid of schematics and a fully developed construction manual. Information was provided about cost, building styles and thermal efficiency. Thickness of the geodesic panels can vary and are selected by the owner in a best described as you “Get What You Pay For” in home comfort and cost of utilities.

Sure, I had a few problems along the way but that was with the Contractor and the need to have 8 foot vertical walls due to the Deed Restrictions. AI helped in each stage from scheduling the delivery to being available for consultation as needed. We had to modify the Schematics a couple of times but with the prints in a AutoCad based system that was promptly taken care of.

I now have a 45 foot structure like no other I have seen. A full Cupola with casement windows which provides complete ventilation. The Concrete skin of the panels have proven their worth over the years. I live in a Hail Zone and the homes that were built with conventional shingles have been replace 3 times. Only steel roofs and those with concrete tile have survived. Even then some damage was experienced by my neighbors. Yes, I am happy with my choice 23 years later.

34′ Dome on full basement in Colorado which is 15 years old:  Toni told us: “I built the American Ingenuity dome for my retirement home and now that I am retired I am so glad that did. I love my dome.  In 2014 we experienced a hail storm that beat the paint off part of their dome & damaged a vent. There was no damage to the concreted panels. To warm the dome in the winter I designed the windows to face south to let the sun in, I installed baseboard heaters that are heated with hot water and I use propane to heat the water in the boiler.  For back up I have a small gas stove.”  Above are two pictures of her dome.


Twenty-five year old Florida AiDome Home Built in 1992

Three dome complex consists of 40′ dome home linked to a 30 garage dome with separate 22′ work shop dome (not visible on the right).  In an 8/2/17 Florida Today article, the reporter wrote:

But perhaps one the best selling points, the couple added, is the home’s safety features. Terry explained that the geodesic home is built to endure up to 225 mph winds, and is energy efficient. The couple said they have not paid more than an $80 electric bill since living in the home. 

“We’ve never had to evacuate (during a hurricane),” said Terry. “And we’ve never had any hurricane damage.”

This a quote from them and above are two pictures.

“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” 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.”

From R. Whaley, Florida: “Once the dome is initially heated or cooled, the temperature remains constant. Just think of when you take your soda pop to the beach on the hottest day of the year in an inch thick foam cooler. Once the house gets cool or hot as desired, it retains that temperature and stays constant.” In 2004 their dome went through two hurricanes. The following is their comments on the storms: “We live in a 34′ dome one block from the ocean. Our domes went through Hurricane Frances and the exit winds of Hurricane Charley. During the hurricane we could hear things hitting the domes. In the morning we walked around the yard and picked up shingles and soffits from other people’s houses and washed off our driveway. It was as if nothing had happened at all.” (34′ dome home and 27′ dome garage)


From the Mathes, Florida: Their 34′ dome home with 30′ garage dome utilize a solar water heater and photovoltaic panels to power their lights and refrigerator. Although, their A/C, washer, well pump and TV are still connected to the meter, their total electric bill was less than $150.00 for the year. The owner/builder also states, “This has been a wonderful experience that I would not trade for ANYTHING!”

Per Eric, “The Dome is very efficient and strong. It has been hit by several hurricanes and tropical storms with no damage at all. My neighbor’s conventional house was severely damaged by the storms. I keep the house at 72 degrees in the summer and warmer in winter. My electric bill is around $100 a month with no water/sewer bill because I’m on well/septic. The house is designed for very little maintenance.”

From the Sparrows, Florida Keys: “We call our home ‘Sparrows’ Nest’…it’s pretty strong. It may look small from the outside, but…there’s a lot of room. The house is a rock.” (30′)

From the Clarks and Sayles, Ft Pierce Florida: “The eye wall of Hurricane Frances sat on us for two hours so the category 2 hurricane did category 3 damage. We experienced 120 to 130 mph winds with no dome damage while the house across the street lost most of its shingles.”

From the Woods,  Florida: “We were in the direct path of Hurricane Charley. We had winds greater than 145 mph and our dome had no problems. One widow got a crack from debris. Most of our town was destroyed and all three area hospitals had roof damage. Thank you for our dome.” (40′ dome and 27′ garage dome)

From the Vandebergs and Delongs, North Ft. Meyers Florida: “Thank you for our dome. The eye of Hurricane Charley passed only 15 miles from our dome. We had 117 mph sustained winds. Our domes stood strong. The only vulnerable part was our garage door. We used 2×4’s, plywood and sandbags to keep it from blowing in.” (34′ dome and 27′ garage dome)

From the Drybolas, Milton Florida: “Our neighborhood looked like a war zone. We were in the direct path of Hurricane Ivan and had the full blast of the winds plus there was a tornado in our area. Our concrete domes were wonderful and suffered no damage, despite winds of over 135 mph. Pine trees were stripped of bark and needles and many were lying on a 45 degree angle. Firefighters came by our dome and told us ‘You have the right house for this storm.’ We’ve had over 200 people stop by and see our dome. Believe me your product has never been shown off as good! Wish more people by the beaches, who lost everything would come by, sure wouldn’t have to worry anymore.” (45′ and 30′ with 34′ screen dome)

From the Hendersons, Santa Rosa Beach Florida: “We had over 135 mph winds from Hurricane Ivan and our domes suffered no damage. Our domes are close to the Gulf and sit about 56′ above sea level. This is higher than the surrounding houses so we received the maximum of any wind force, yet we received no damage. (48′ and 34′)

From L. Sawh, Florida: “It’s hard to believe, but we finally finished this house of ours! It’s taken us a good year and a half but its all been worth the hard work and challenges. We began with some designs on paper, added some features of our own, took a few suggestions from other dome owners and with a lot of sweat and pain, not forgetting our subs and the folks at the bank, here we are!!!” (40′ and 27′ Garage dome)


From R. Napolitan, Idaho: “The dome is snug and warm. We heat it mostly with a woodstove that’s in the basement. Our staircases are open so the heat rises. It stays about 68 degrees without much effort, with our lowest outside temp…5-6 degrees. (2,000+ sq.ft. with basement, 34′)

From B. Gates, Illinois: “I’ve never been too much of a conventional person. I thought this was a pretty neat design, very energy-efficient. I like to keep things environmentally nice. It’s almost an organic feeling, being surrounded by curves instead of by rectangles. It seems to be a more relaxing environment to be in.” (48′)

From D. Partlow, Indiana: “The dome is ‘awesome’, ‘beautiful’ and ‘breathtaking’. At least that’s what visitors say. It is and it’s also a very comfortable home to live in. Our June electric bill was $107, we are total electric! We still love the house and the great savings on energy!!!” (2,400+ sq.ft.; 48′)

From S. Mumphrey, Louisiana: “We’re three years in our dome…we still pinch ourselves every morning thinking its a dream. But, it’s REAL and we love it.” (45′)

From L. Gillis, Michigan: “I don’t see how a city can ignore one of the great architectural breakthroughs of the 20th Century. A city without geodesic domes, is not thinking about progress. It’s thinking about replicating the past. A city cannot be a world-class city, unless it has some geodesic domes.” (45′)

From H. Willis, Mississippi: “I like the openness. You can see the kitchen, dining room, living room and bedroom loft when you walk in the front door.” (34′ with 25′ screen dome)

From L. Covington, North Carolina: “Doing everything on my own, not too bad when I think that it will save me $25,000 in labor costs for doing everything outside and inside….The folks that ride by are trying to break their necks gawking at the dome. A curiosity for folks I guess and a few have stopped for more info and a lot come back from time to time to check the progress….” (30′)

From J. Chang: “Thank you again for being the great company that you are! Keep us in the loop with information on finishing touches.” (48′)

From K. Millar, South Carolina: “What this house is about is alternatives.  We decorated it with an Oriental theme, even painting the floor with an Asian motif and we surrounded the house with a Japanese garden.” (40′)

From R. Scripps, Texas: “I like to thank you again for the advice you have given me and Dale.” (Two 45′ domes on full basements)

Finally, Mary announced to me that she had found our house; a precast concrete and eps geodesic dome kit! Although I wasn’t wild about the look of a dome house, as an engineer I was excited about the sheer practicality. I quickly ran some heat loss calculations and found that at -20 degrees F, we could expect to keep the 2700 sq.ft. of living space at 70 degrees F using little more than 30,000 btuh, about 1/3 the size of a conventional home furnace. With judicious use of a large solar window and a masonry heater fireplace, we could limit our use of propane for backup heating.” (45′ and 30′ Garage dome)

Building Options – entryways, dormers.  Why do I need entryways and dormers to install windows and doors? At specific locations around the perimeter of the dome, triangles and riser panels can be left out to provide openings where you or your framer installs your locally purchased doors and windows. To structurally compensate for the triangle and riser panels being left out, these “structural awnings” – entryways, dormers or cupola have to be installed.

The Ai dome kit consists of all the triangular panels, four foot tall riser panels for the dome shell and panels for one entryway.  The exterior of each triangle or riser panel is 3/4″ fiber concrete reinforced with galvanized steel mesh with a center of  7″ Expanded Polystyrene (EPS) with interior 1/2″ Georgia Pacific DensArmor (moisture resistant/mold resistant gypsum wallboard) adhered to each riser and triangle panel.  Your floor plan selection determines how many more entryways (standard, garage or high profile), window dormers, door dormers, cupola, link, etc. will be ordered. The link is used to connect two domes together. The building kit does not include any doors or windows and does not contain any interior items (except for the interior shell wall board).  American Ingenuity believes that you should not pay shipping on items that can be purchased locally.

Dome Building Options

The Building Options for the American Ingenuity dome include: Entryways, Cupola, Window Dormers, Door Dormers,Garage Domes, Links, 5′ riser panels for 22′ & 27′ domes, 2′ additional riser panels for 30′-48′ domes and 9″ thick insulation. These options (except for the links and insulation) allow for openings where your locally purchased standard doors, garage doors and windows are installed within a 2×4 or 2×6 framed wall that is built on site.

The 15′, 18′, 22′ and 27′ domes are two frequency domes. The 30′, 34′, 36′, 40′, 45′ and 48′ domes are three frequency geometry.  The 60′ dome is a four frequency dome. The frequency and dome size determines the size and number of the panels.  Sometimes second floor triangle shaped panels are too small to accept window dormers or door dormers.  As a result each dome diameter has specific locations where entryways, window dormers and door dormers can be installed.  The following description of possible locations can be confusing so just call us at 321-639-8777 for clarification.  To view dome kit regular pricing and sale pricing, please click on Sale.

(15′ & 18′ Pricing)

*Because the 27′ dome is a two frequency dome, its panels are about the size of 40′ panels.  As a result the 27′ cupola pricing is the same as the 40′ cupola.

To view floor planners and elevation views for each dome size that show where entryways and dormers can be installed, please click on Planners.  Scroll down the page to find the blue hyperlinks to click on.  After the stock plans for each size dome you will find the floor planner and the elevation view.  The following is a summary of which size domes can have which building options.

    1. There can be up to five standard entryways on the first floor of Ai’s 30’, 34’, 36′, 40’, 45’, and 48’ domes.  Instead of using entryways, install first floor window dormers and door dormers in specific locations.
    2. The 30′, 34′, 36′, 40′, 45′, and 48′  domes can have standard entryways and high profile entryways. High profile entryways can be installed where there is no second floor.
    3. The 22′, 27′, 30′, 34′, 36′, and 40′ domes can have two garage entryways. When the domes are designed for a home, the entryway is called G type entryway.
    4. The 15′ & 18′ can have one or two G type entryways.  To view plans and info, click on Tiny Domes.
    5. There can be up to five window dormers on the second floor of the 27′, 34′, 36′, 40′, 45′ & 48′ domes.  A window dormer can be installed above a high profile entryway.
    6. American Ingenuity is the only geodesic dome kit manufactured that has designed second floor door dormers that utilize the top of the standard entryway as a balcony.  Railing is custom built on site.  There can be five second floor door dormers in specific locations in the 34′, 36′, 40’, 45’ and 48’ domes. Second floor door dormers have to be installed above first floor standard entryways. Door in 34′ second floor door dormer is 2’x6′ – door has to be custom cut on site.  Door in 36′ second floor door dormer is 2′ x 6’8″ – has to be custom ordered.  Door in 40′ & 45′ second floor dormer is 2’6″x6’8″.  Door in 48′ second floor door dormer is 3’x6’8″.  2nd floor bedrooms in 34′ dome require a fire egress window be installed in a second floor door dormer.
    7. The 15′, 18′, 22′ and 30’ domes can have first floor window and door dormers but cannot have second floor door dormers or second floor window dormers.  See elevation views on Tiny Kit link.
    8. Cupola can be installed on top the 22′-48′ domes.
    9. The 27’ can have first floor window and second floor window dormers but no second floor door dormers.  The second floor window dormers on the 27′ dome can accept fire egress windows.
    10. On the second floor of the 36′, 40′, 45′ and 48′ domes there can be a combination of up to five second floor door dormers and or window dormers.
    11. The 22’ and 27’ domes are typically garage domes.  On the first floor of a  22′ dome there can be one garage entryway (that can contain a 9′ wide garage door), one door dormer and up to five window dormers.  On the first floor of the 27′ dome there can be two garage entryways (which can contain a 16′ wide garage door), one door dormer and up to four window dormers.  If you connect a link to a 22′ dome, the link is about 5.5′ to 6′ wide with a standard length of 5′.  If you connect a link to a 27′ dome, the link is about 6.75′ wide and has a standard length of 5′.  

What types of windows and doors are possible? Standard windows and doors can be installed within the entryways, window dormers, door dormers and cupola of most of Ai’s domes.  However for second floor window dormers in a bedroom in specific domes, the fire egress casement window is ordered with egress hardware. If a fiberglass door is desired for second floor door of 36′ dome then a custom 2′ x 6’8″ door is ordered from Therma Tru. 

The Ai building kit contains all the panels to assemble the dome shell and the panels for one entryway. The Kit does not include doors and windows. There is such a variety and varying price points, Ai leaves the selection up to each client to purchase and order locally. The floor plan selected will determine where you or your builder will install your locally purchased doors and windows.

Where do windows and doors get installed in the Ai building kit? Under the entryways, dormers or cupola. These are structural “awnings” that extend out from the dome. Within the open area under the “awning” a vertical 2×4 or 2×6  framed wall with appropriate headers is constructed on site to fit your choice of doors or windows. Ai has designed the entryways and dormers in a manner to allow the owner to select from the wide variety of windows and doors that are locally available. Click on Window Sizes to learn more.


Entryways in the 3-frequency domes (30′, 34′, 36′, 40′, 45′ & 48′) can be standard, high profile or garage.  A standard entryway is 8′ tall and provides an opening where standard 6′ 8″ doors can be installed.  High profile entryway allow enough height that 8′ tall doors can be installed or glass can be installed above standard 6’8″ doors.  Garage entryways are used in garage domes and are the type entryway used in the 22′ & 27′ domes.  To view the widths and heights of all the domes entryways, click on Specifications.

Only garage entryways are available in the two frequency domes (15′, 18′, 22′ and 27′). Entryway panels for the 15′, 18′, 22′ and 27′ dome consist of 3 1/2″ thick E.P.S wrapped in galvanized steel mesh.  There is no concrete on the 15′, 18′, 22′ or 27′ entryway panels.  

Entryway panels for the 30′, 34′, 36, 40′, 45′ and 48′ domes utilize 3 1/2″ thick E.P.S. wrapped in steel mesh, are preconcreted on the underside surface and have a precast trough on the outer edge. On site form up the back side of the trough, place rebar in the trough, fill the trough with concrete and concrete the outside surface per your building plans.. The openings under the entryways are framed in on the site to fit your choice of standard windows and doors that you purchase locally.

Window Dormers

Window dormer panels consist of 3 1/2″ thick E.P.S. wrapped with steel mesh ready for on site stucco. The openings under the dormers are framed in on site to fit standard windows that you purchased locally. Click on Window Sizes to learn more.

If I want to install a single window what option do I use? First Floor Window Dormers or Second Floor Window Dormers.

On the first floor of the dome, window dormers are installed above any riser panel in all of the Ai domes. Install a second floor window dormer in any of five locations in the 27′, 34′, 36′, 40′, 45′, 48′.

Second floor window dormers are not available in the 15′, 18′, 22′ or 30′ domes. To obtain additional light on the second floor of these domes, install solar tubes by cutting a hole in the preconcreted panels & installing the solar tube per the manufacturer’s directions.  In the 30′ dome use a cupola where five standard opening windows can be installed. For indirect light install solar tubes. (When installing do not cut within 8″ of the center of a seam.)

Can a window dormer  be installed above a high profile entryway? Yes.

What do the window dormers consist of? Three panels of precut 3 1/2″ E.P.S. wrapped with steel mesh. After the window dormers are installed in the dome shell and its window framing installed, concrete is applied on site.

To obtain a building permit is a certain size window required in a bedrooms to meet fire egress? Yes. Code requires first floor bedroom windows to be at least 44” from the floor. Second floor windows cannot be more than 44′ above the floor and cannot be less than 24″.  The window has to be 20″ horizontal dimension by 24″ vertical dimension. When the window is open it has to have 5.7 square feet of opening space. The spec sheets for bedroom egress windows have to state Fire Egress.

If your building department requires an Energy Report to be submitted to obtain a building permit, your building plans will include an exterior door and window chart.  During plans design, Ai emails elevation views of the entryways and dormers showing recommended window and exterior door sizes. The homeowner visits window stores (Home Depot, Lowes, etc.) and selects windows and exterior doors providing Ai specific energy info which will be included in the energy report.  In Florida and other states the building department wants spec sheets submitted on the doors and windows and doors when submitting for a building permit.  The spec sheets show the window and door manufacturer, model numbers, product approval numbers and provide the manufacturer’s spec sheet that shows the windows and doors comply with that area’s wind speed requirements. Florida and some states require impact resistant glass or shutters in certain wind speed areas.

Door Dormers

Where can door dormers be installed? On the first floor of the all the Ai domes and on the second floor of the 34′, 36′, 40′, 45′ and 48′ domes.

First Floor Door Dormers: are a way to install a single door. The first floor door dormer can replace most riser wall panels on the ground floor of all the domes. Utilize first floor door dormers for single exterior doors such as kitchen or garage exits. Like window dormers, the door dormer panels are precut from 3 1/2″ thick E.P.S., wrapped in steel mesh and are stuccoed on site during construction.

Second Floor Door Dormer: Pair a second floor door dormer with a standard entryway for an upstairs balcony in the 34′, 36′, 40′, 45′ and 48′ domes. Structural door dormers may be located in any of five locations on the second floor of the 34′, 36′ thru 48′ domes.  A second floor door dormer cannot be installed above a high profile entryway.

Door in 34′ second floor door dormer is 2’x6′ – door has to be custom cut on site.  Door in 36′ second floor door dormer is 2′ x 6’8″ – has to be custom ordered.  Door in 40′ & 45′ second floor dormer is 2’6″x6’8″.  Door in 48′ second floor door dormer is 3’x6’8″.  2nd floor bedrooms in 34′ dome require a fire egress window be installed in a second floor door dormer.

Second floor door dormers are not available in the 22′, 27 or 30′ domes.

Riser Panels
Q:  Please explain about the Riser Panels that come with each kit.

American Ingenuity includes four foot tall riser panels in the building kit at no extra cost.  The new Tiny Dome kits 15′ and 18′ come with standard four foot risers and additional two foot risers.

The four foot tall riser panels allow for more vertical space near the perimeter of the first floor and greater headroom on the second floor.  Because of the spherical dome shape, 30% to 50% of the first floor is left open so that the living room and dining room are located under high vaulted ceilings.  This allows for a partial second floor to be installed.  The first floor ceiling height in the 22′, 27′, 30′, 34′ & 36′ domes that have a second floor above them is 7 1/2 feet.  The first floor ceiling height in the 40′ and larger domes that have a second floor built above them is 8′.

Q: Can the first floor ceiling height in rooms that have a second floor built above them be taller than 7 1/2′ or 8′?

A:  Yes.  Instead of installing four foot risers in the 22′ & 27′ domes install a five foot riser resulting in 8’6″ ceiling height in rooms on the first floor that have a loft or second floor built above them.   In the 30′ – 48′ domes, purchase taller entryway base panels and custom Two Foot Tall Riser Panels that are installed above the standard four foot tall risers.  This results in the first floor ceiling height of rooms not under high vaulted areas of

  • 9’6″ for 30, 34, 36′ Ai domes
  • 10′ for 36′ dome when there is not a second floor door dormer
  • 10′ for 40′, 45′ and 48′ domes.

Q: Does installing a 5′ riser instead of 4′ risers in the 22′ & 27′ dome or adding 2′ risers above the 4′ risers affect the second floor height?

A:  No.  Taller risers only give additional height on the first floor and increase the over all height of the dome.  The second floor is not affected.  The placement of the second floor window dormers and door dormers has to remain where they are designed to meet second floor fire egress standards and correct second floor door installation.


Ai recommends that you build the cupola only if you want a third floor loft or to have a second floor area to install standard opening windows in the 30′ dome. The cupola is a way to add height to the top center of the dome and another way to have opening second floor windows – but adds costs to construction & increases window budget.  A different way to add light to a second floor is to max out second floor window dormers or install solar tubes.  Install an exhaust fan in top center of the cupola to exhaust hot air and water vapor.   With the installation of a cupola, there is enough headroom in the 40′ and larger domes to have a third floor loft.

Cupolas require three partial days for assembly because the concrete has to have time to cure during each process (this does not include framing  for the windows or the installation of the windows).

    1. First Partial Day of 5 hours: concrete beam around top opening is formed and poured.
    2. Second Partial Day of 5 hours: concrete corner columns are framed and poured.
    3. Third Partial Day of 5 hours: set top five panels, attach overhang panels and apply first coat of concrete in their seams.
    4. During the rest of the partial days, workers can complete window dormers and door dormer installations.

 Interior Shell Finishing

Once the Ai dome building kit is assembled, the 1/2″ Georgia Pacific DensArmor gypsum wall board on the interior of the dome shell is ready to be finished. To install wiring cut a groove in the wallboard & EPS behind where baseboard will be installed and insert wiring.  Where electrical outlets will be installed, cut groove up the wall to the outlet height, insert wiring, use expanding foam to fill the groove and then finish area that is above the baseboard with tape and joint compound. Groove behind the baseboard does not need to be filled with expanding foam.

Applying a textured paint using 50/50 mixture of paint and joint compound will likely hide the board seams.  Or you can apply joint compound to the DensArmor after the wallboard is primed in what is sometimes called a skip trowel finish, apply primer coats and paint.

9″ Thick Expanded Polystyrene  (E.P.S.) Insulation

The standard insulation in Ai’s dome building kits consists of seven inch thick, rigid, nontoxic expanded polystyrene (E.P.S.) or R-28 which is comparable to eleven inches of fiberglass batting.  Or purchase thicker 9″ E.P.S.  To learn more about E.P.S. as a vapor barrier click on Vapor Barrier.

Ai domes with 7″ E.P.S. will easily outperform conventional housing with 11″ thick fiberglass insulation.  Instead of purchasing thicker EPS, purchase triple panned windows and insulated doors.   Windows and doors are where your cooled or heated air will escape.

The cost of the 9″ E.P.S. is the cost to upgrade the 7″ E.P.S. to 9″ E.P.S. for the entire component panel kit. Dormer and Entryway panels utilize 3 1/2″ EPS as a rigid form.


Domes are connected together with a Link which consists of E.P.S. insulation with steel mesh attached on site (mesh can be purchased from Ai) and concrete applied on site.  The Link panels consist of precut 3 1/2″ or 7″ thick E.P.S.  The Link EPS panels can be purchased with wallboard adhered.  On site assemble the Link E.P.S. panels, cover them with steel mesh and coat them with the fiber concrete.

The Link connects to the adjacent domes in the same locations as an entryway or a door dormer. This connection is a custom fitting on site. The thickness of the E.P.S. in a Link is usually 7″ when it takes the place of an Entryway and 3 1/2″ when it connects at where a door dormer would have been located. The width of the links depends on the size of the domes and whether the domes are connected at an entryway or door dormer. The length of the Link is usually 5 ft.  Because the riser wall is a standard 4’ high, all domes will match each other despite a difference in diameters.

The width of the link that connects to the 22′ dome is about 5’5″ to 6′ wide.  The width of a link that connects to a 27′ dome is about 6.75′ wide.  If the link connects onto domes 30′ or larger the width of the length where it connects to the larger dome varies depending upon whether the link connects to the larger dome at a door dormer or a standard entryway. For example, if the link is connected to a 45′ dome at an entryway (taking up two risers) the width of the link where it connects to the 45′ dome might be 13′.  These are approximations, the Plan’s Supervisor will give you a more accurate number, once he sees your plans sketches.

Ai does not recommend extensions to entryways for the following reasons.  Extensions add exposed surface area faster than they add floor space therefore reducing the energy efficiency. Extensions add to the cost of construction faster than they add floor space therefore increasing the cost per square foot.  The long flat roof of the link or extension connects to the curved dome…the link/extension and the dome expand and contract at different rates…a crack will occur where they meet.  Ai recommends applying elastomeric patching compound & elastomeric paint where the link panels abutt the dome panels.

American Ingenuity’s Assembly Manual does not include extensions although they are assembled much like entryways or links.  In general, domes have inherent advantages because of their shape and deviations away form the dome shape lessons the advantages.  However if you desire, extensions Ai can design and manufacture them.

The E.P.S. link panels range in price depending on the length of the link and the size domes the link connects to.  Once your plans are finished Ai will know the length and width of your link and can calculate the link’s EPS panel’s pricing, steel mesh pricing and and wallboard pricing.

Garage Dome Kits

Do you have separate garage dome kits available? Yes.To view the garage stock plans, garage floor planners & garage elevation views for the 22′, 27′, 30′, 34′, 36′ and 40′ domes, please click on Planners and scroll down the page to find the Garage Dome heading.

Ai has developed two garage dome sizes, 22′ and 27′. These garage domes are two frequency icosahedron geometry. This geometry differs from Ai’s other domes in that it utilizes fewer but larger panels. By having larger panels Ai can create a wider opening that is needed for a garage door. You can install a 9′ wide garage door in the 22′.  The 22′ dome can have a storage loft of 148 sq.ft.  The 27′ garage dome can have a 16′ garage door and the 27′ dome can have a second floor of 231 sq.ft.

Previously a 34′ dome was needed to park two cars. Now a two car garage in a 27′ dome is available which is more cost effective. The 22′ dome provides an economical one car garage. Either of these garage domes can be connected to another dome or built independently from the house.

The 27′ or 34′ garage dome is utilized when you want more first floor perimeter room around the vehicles or when you want a second floor above the garage for an apartment or study, etc.  The second floor of the 34′ dome can have 427 sq.ft.

You can find the pricing for the garage kits on the bottom of the Stock Floor Plan Price List that is in the Stock Floor Plan Booklet.

With the savings on the dome kit,

beautiful flooring and kitchen cabinetry can be purchased

Ai’s dome shell kit price is one fourth to one half less in cost than the shell materials cost for a wood dome, monolithic dome or conventional house (exterior walls, roof trusses, plywood, tar paper, shingles, 3 1/2″ thick insulation, siding, soffits, gutters, shell and ceiling/exterior wall – wall board, etc).  Besides saving on your shell materials cost versus the materials for the shell of a conventional house….you receive more with the Ai Dome Home….greater energy efficiency (insulation comparable to 11″ of fiberglass batting), greater strength and lower maintenance because the exterior of your dome home is concrete with no wood in it or on it to rot, to burn or for termites to eat.

Why is the Ai Dome Kit so reasonable in price?  Mainly it is because of the simplicity of Ai’s component panel, the panel being manufactured in a factory and the philosophy of our company that each client pays for only what they need; i.e. building plans, engineer seal cost, energy report is paid by only those who need it.  To learn more about our philosophy, view Philosophy.  To learn more about Ai’s panel composition, view Composition.

Q: Do you have an engineering statement about your dome panels that can be submitted to my building department?

A:  Yes, to view the statement click on Engineering.

To view a building plans sale pricing chart, view Plans Discount.

Ai’s Building Kit and Option Pricing does not include the costs for the Building Plans, Engineer Fee for alternative foundation design other than slab, Engineer Seal on the building plans (if needed), Energy Report (if needed), 2×4’s for the temporary wooden rib system, Semi-truck Shipping, Fork Lift rental to unload the truck at your site or the cost for a hoisting mechanism to lift the panels into place. 

Please view Kit Assembly Consultant file and scroll down the page to view the yellow and blue charts showing estimated labor costs, hoisting mechanism costs, etc.

The money you save by purchasing Ai’s Building Kit can pay for all of the above costs.  For example if you purchase a $30,000 building kit from American Ingenuity,  the shell materials for a conventional house can cost at least $10,000 to $15,000 more especially if you build the conventional house energy efficiently with 2×10 walls and 10″ thick insulation.  Ai asks you to make a comparison chart comparing what you receive in the Ai kit compared to the contents of a log home kit or conventional house kit or Deltec kit.

The most successful dome kit assembly occurs when the home owner or the home owner’s builder hires the independent Consultant to supervise the Kit Assembly. Once the shell is erected, then you or your local contractor hires local subs to finish the conventional jobs of plumbing, electrical, framing, flooring, cabinetry, window and door assembly, etc.  To learn more about the Consultant, view Consultant.

  • 2×4’s for the temporary support system.  The 2×4’s are cut to specific lengths, holes drilled for the bolts and each end painted red, white or blue.  Ai can cut them to length, drill the holes and paint each end.  For pricing call our office:  321-639-8777.
    • The 34′, 36′, 40′, 45′ and 48′ each require 135 – 2×4’s.
    • The 22′ and 27′ each require 75 – 2×4’s.
  • Additional supports for the temporary support system – around 20 – 8′ 2×4’s and 33 – 10′ 2x4s for smaller domes.
  • Steel Scaffolding
  • Work Platforms:
    • For work platforms greater than 6’ long use a 2×4 under a 2×10 platform.
    • You will use scaffolding brackets, 10d duplex nails, 5/16” lag screws, 2×4’s 10’ long.
    • The work platform can be extended around the dome by overlapping another 2×10 and adding another post.
    • Nail overlapping platforms together.
    • Each platform will hold one person.
    • Be sure to use safety rope and a harness.
  • In the Kit Assembly Manual is complete Tool, Material, Utility listing.
  • Rental of a hoisting mechanism
  • On your Order Form there is a listing of items that come with your kit with quantities: for fibers, admixtures, bonding agent, cans of expanding foam, metal dispensing gun, cleaner for gun, C-rings small and large, C-ring pliers, two steel cables, etc.  Due to spillage and loss at job site, our clients tend to purchase additional quantities of these items that are shipped on the truck with their kit.  This saves on later shipping costs.
  • Labor to install the cement in the seams, entryways, link, cupola, and dormers. View Kit Assembly Consultant to learn more about this.
  • Labor, Joint Compound and Tape to finish the interior shell wall board seams.  Primer to prime the shell drywall.
  • All interior items (excluding the interior shell wallboard which comes with the Building Kit):  Plumbing, Electrical, Framing, HVAC, Bathroom fixtures, Lighting Fixtures, Kitchen Cabinets, Appliances, Foundation, Flooring, Stairs, Lift or Elevator, Windows, Doors (exterior and interior).  Due to the wide assortment of these items and varying price points, Ai does not believe you should pay shipping on items that you can purchase locally.  View Dome versus Stick Built to learn more.

Hoisting Methods

The methods used for lifting the panels includes: Man Lift, cranes and Highlifts (all terrain scissors forklifts often used by roofers).  To view more on hoisting methods, click on Lifting.

Monthly rentals on transverse lifts also called Boom Lifts, Horizontal Boom Fork Lifts, Roofing Lifts, Shooters are available from National Rental Chains like US Rentals, Hertz Equipment Rentals, United Rentals, etc. The companies can be found in the telephone book.

The panels for the domes are best placed using a man lift or crane that is capable of lifting 300-400 pounds, 25 feet up and 25 feet out.

With a four-person work crew, use of a temporary wooden rib system and proper bracing of the panels, a row of panels of a 40′ dome can be placed in about a day of crane time.

Man Lifts or cranes can be rented by the day, week or month. Sometimes larger domes with three to five entryways, the rental of a crane for one month maybe most cost effective. Besides lifting the panels, the crane can be used to lift buckets of cement. Cement is used to fill the seams between the panels and to stucco the entryways, dormers, link and or cupola.

Wooden Rib System Is Needed As Temporary Support During The Dome Kit Assembly

American Ingenuity’s Dome Building Kits are erected using a system to temporarily hold the panels in place until the seam concrete and concrete on the entryways, dormers, cupola and link has cured and the entryways and dormers are framed in. The system is dismantled upon completion of the dome and the 2×4’s are recycled as part of the interior framing. For example, around the perimeter of the second floor a two foot tall knee wall is built. 2×4’s not tall enough for interior framing can be used for the knee wall. Behind this knee wall, electrical, plumbing or ducting can be run or the space can be used for storage. View Rib.

The Rib System consists of using your own 2×4’s (that have been cut to length, holes drilled and the ends painted red, white or blue (or you can purchase them cut, drilled and painted from Ai…call 321-639-8777 for pricing) and the steel hubs on loan from America Ingenuity to assemble a free standing framework which matches the geometry of the dome.

  • The rib system dictates exact panel placement.
  • Once all the seams, entryways, dormers, link, cupola, etc. have been concreted, entryways and dormers framed in and the concrete has cured, the rib system is disassembled, the hubs are returned to American Ingenuity and the 2×4’s are recycled as interior framing.
  • As the building kit is being assembled upon the temporary wooden rib system, extra 2X4’s are used to support each steel hub.
  • The advantages of using the Rib System Option versus the Radial System Option are:
    • Since the Rib System reflects the dome geometry, a panel cannot be inadvertently positioned incorrectly.
    • The Rib System is most suitable for accurate assembly.
    • The hub rental charge is a $800 deposit with the hubs being kept for five months. After that the rental fee is $20 per month. If the hubs are returned to us intact within the five month period, the complete $800 deposit is returned. The hubs are returned to Ai via UPS or common carrier at the client’s expense.
    • The Rib System is bolted together from 2×4’s and color-keyed hubs. 

Tools and Materials needed to assemble the Rib System (complete list is in the Manual):

  • Set of steel scaffolding to reach at least the dome height plus three feet (the dome height can be estimated by taking one half of the diameter of the dome.)
  • 9/16” wrenches and ratchet
  • 46 hubs (borrowed from Ai for three frequency dome), 255 bolts, nuts, and washers purchased from Ai
  • 15 diagonal braces: 2x4x8’ studs
  • Chain and couplers to make the lifting harness which is used with the lifting spikes
  • Precut, holes drilled and color-coded wood ribs (2×4’s used are lightweight wood, not pressure treated)
    • The 34′, 36′, 40′, 45′, and 48′ rib system requires 135 – 2×4’s
    • The 22’ and 27’ need 75 – 2×4’s
    • If you do not want to buy the 2×4’s and cut them to length, color code them and drill the holes, purchase them from American Ingenuity. Due to the fluctuating cost of 2×4’s, we estimate the cost when ordered.
  • Two pounds 12d or 16d common nails and 60d nails (in top of hub support)

 The American Ingenuity dome building kit does not include doors and windows. There is such a variety and varying price points possible, we leave their selection and local purchase up to each client. The floor plan you select will determine how many entryways or dormers you will have. Within the entryways and dormers {eye brows}, you or your framing subcontractor installs a vertical wall to frame in what ever standard doors or windows you have purchased locally.

No interior items are included except for the dome shell wall board. Ai believes you should not pay shipping on conventional items that you can purchase locally such as: foundations, basement wall kits, second floor joists, stairs, plumbing, electrical, framing, flooring, kitchen cabinets, bathroom fixtures, lighting fixtures, etc.

The component panels do not come with any paint on them. Ai does not add any color to the concrete. On site concrete is applied to the seams so if Ai painted the panels or added color to the concrete it would not match your seam concrete. The concrete shell is primed and painted after the entire building kit is assembled. The painting should include a concrete primer and two coats of good quality paint. Ai dome owners recommend Ames products to prime and paint the dome which can be purchased at Ace Hardware and True Value for similar Home Depot and Lowe’s paint pricing. When on Ames site click on Local Dealers to find other suppliers in your area. The dome can be painted any color, tan, blue, green, etc. preferably a light to medium color to reflect the sunlight. The following gallon calculation is for each coat of primer or paint.

To view Dome Diameters in Meters and floor plan square footages in square meters, select page 2.

American Ingenuity manufacturers ten different prefab home kit sizes also called Modular Home.  Domes are measured by diameter in feet.  The 15′ & 18′ & 22′ domes can have a first floor only with optional attic/loft while the 27′, 30′, 34′, 36′, 40′, 45′ and 48′ domes can have a second floor framed with wood 2×10 joists.  If a cupola is installed on top of a 40′, 45′ or 48′ dome there is enough interior height to install a small loft area under the cupola.

The floor plan selected determines how much of the second floor is installed. Where a second floor is not installed there will be high vaulted ceilings over first floor areas.   It is typical that one half to two thirds of the second floor is installed.  However any of the domes can be  built with no second floor.   Below are pictures of some of the dome sizes.

Ai’s Tiny Home Kits 15′ & 18′ come with 4′ risers and additional 2′ risers.  A’s 22′ – 48′ dome kits include four foot tall riser panels before the triangle geometry.  Ceiling Heights in first floor rooms that have second floor installed above them is either 7′ 6″ or 8′.   22′, 27′, 30′, 34′ & 36′  kits – 7’6″.   40′, 45′ & 48′ – 8′.

How to have 8’6″ or ten feet first floor ceiling heights in rooms with a second floor installed above them:  In 22′ & 27′ domes custom order five foot tall risers instead of the standard four foot tall risers which results in eight foot six inch ceiling height.  In 30′, 34′, 36′, 40′, 45′ & 48′ domes order taller entryway panels and custom  2′ risers to install above the standard risers to result in either 9’6″ or ten foot first floor ceiling height in areas where a second floor is installed above the rooms.

DOME GEOMETRY: Frequency is the number of intersections from the center of one pentagon grouping to the next pentagon grouping.

  • Ai’s 15′, 18, 22’ and 27′ domes are 2-frequency, 1/2 spheres on a 4′ vertical riser.  The 15′ & 18′ kits come with 4′ riser and additional 2′ risers. Instead of the standard four foot riser panel, a five foot riser panel with taller entryway panels can be ordered for the 22′ & 27′ kits.
  • Ai’s 30’, 34’, 36′, 40’, 45’, and 48′ domes are 3-frequency, 3/8 spheres on a 4′ vertical riser.  On site a one foot or two foot tall wall can be built to install the risers on which increases first floor ceiling height (where 2nd floor built above first floor) to 9′ or 10′.  Or additional 2′ risers can be ordered and installed on the standard 4′ riser panels.

American Ingenuity’s 30′ through 48′ in diameter domes are approximately a one half sphere with a four foot tall riser wall.

5/8 Domes:

  • Ai. finds it more practical to use a vertical 4′ riser wall on all of its domes instead of designing its domes with the 5/8 geometry.
  • Ai’s 30′ dome turns out to be almost the same height as a 5/8 dome.
  • Also the 4′ riser wall makes for a better shaped entryway and allows the dome to link with all of our other size domes.
