Exterior office 34 with 45' with screen dome

American Ingenuity’s (Ai’s) 3,700 sq.ft. Office Domes
can be cooled for less than  $85 a month during Florida’s Hottest Months

To view Annual Electrical Bill Charts for Ai’s Dome Offices, click on links below named Ai Summary Electric Use. Our dome offices are a 45 ft in diameter dome linked to a 34 ft in diameter dome. Both domes are all electric with R-28 7″ EPS insulation.  For example the 2015 SUMMARY shows that it costs a monthly average of $84.85 to air condition Ai’s 3,700 sq.ft. Florida offices for each of the five hottest months of the year. The following describes how we came to this conclusion.  To view our office domes floor plan layouts, please scroll down to bottom of this page to find the pdfs to click on.

In March 2015 no Heat or AC were used, therefore the cost to run everything in our Office (computers, monitors, printers, backup power supplies, lights, well pump, refrigerator )  was $76.28.  To determine the monthly Air Conditioning costs, we subtracted $76.28 from each month’s electric bill to get that month’s Air Conditioning Costs. To obtain our 2015 monthly average Air Conditioning costs, we averaged the five hottest month’s AC costs.  The five hottest months in 2015 were June thru October to equal $424.26 divided by five to make an monthly average AC cost of $84.85 to air condition 3,700 sq.ft.during Florida’s hottest summer months. The thermostat was kept at 74 degrees 8 am -7pm  Monday thru Saturday and 77 degrees at night and on Sunday.

In 2013 we kept the thermostat at 76 degrees during the day not 74 degrees as we did in 2014 and 2015; resulting in increased 2014 and 2015 cooling costs.  Ai did not know it, but the air handler was not working properly during the summer of 2014 so we experienced higher AC costs than should have occurred. The air handler was replaced in December 2014 causing 2015 AC costs to be less than 2014 because the air handler was operating more efficiently in 2015.

FYI, heating Ai domes is even easier than cooling because when heating, the heat generated by computers, refrigerators, dishwashers, clothes dryers, sunlight, etc.  is used and does not need to be overcome as is done during cooling.

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 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 info about Utah dome off the grid, click on Collar domes.

Question:  How did the American Ingenuity dome perform during the Energy Efficiency Study prepared for the U.S. Department of Energy?  Superbly. Test findings were released from a year long study prepared for the U.S. Department of Energy by the Florida Solar Energy Center, a governmental consumer agency, in cooperation with the University of Oregon and the University of Central Florida. This study compared an American Ingenuity dome with an energy efficient conventionally built structure and a super energy efficient Styrofoam house designed by Dow Chemical. It came as no surprise to us that our test dome far surpassed both the conventional house and the Dow test house in being the most energy efficient.

How does the American Ingenuity dome perform in hot or cold climates?  Superbly.   For example American Ingenuity (Ai) can cool its 3,700 sq.ft. dome offices for less than $85 a month in the hot Florida summer months (May – Sept).  The office is kept at 74 degrees from 8:30 am to 5:30 pm Mon – Sat and  77 degrees at night and on Sunday.  To view Ai offices electric bills, please click on Ai Dome Offices.

It is even easier to heat an Ai dome that to cool it.  To cool the heat generated from the following has to be overcome: sunlight, refrigerator motor, computers, dish washer, clothes dryer, stove. To heat this generated heat is utilized.  Klaus Kolb’s South Carolina Ai concrete dome house earned EPA’s Energy Star.  Home Energy Partners certified his home used 61% less energy than in comparably-size housing.   He installed a geothermal cooling & heating system. To view pictures & info about his geothermal system, click on System.  Klaus’s 2003 total monthly average energy bill was $49. This includes the electricity and propane costs for his entire 1,600 sq.ft. – 40 ft. dome.

Jim Collar’s Utah Ai concrete dome buildings operate off the grid by using photovoltaic’s, masonry heater fireplace and passive solar water tubes. To learn more, click on  Off The Grid.

A Florida 1,075 sq.ft. Ai dome home can be cooled for less than $27 a month in the hot Florida summer months.  The home is kept at 76 degrees Mon-Fri 6 pm – 8:30 am.; 76 degrees Sat & Sun and 81 degrees when the homeowner is not at home.

American Ingenuity Domes are in the following Arizona cities: Lake Havaso, Hereford, Ganado, Prescot, Flagstaff. Utah cities of Roosevelt, Moab and Coalville. Such New Mexico cities as Albuquerque, Magdalene, El Prado, Carlsbad, Angel Fire, Las Cruces, Montezuma, Farmington, Ramah, and Sandia Park.

When building an Ai dome in a hot climate, paint it a light color such as tan, light green, light blue, etc. to reflect the sun light.  One of Ai’s Florida clients cooled their 2,600 sq.ft. dome home for less than $134 a month in the hot summer months when their prior 1,500 sq.ft. box shaped house cost $150 a month to cool. 

The insulation in the Ai dome consists of seven inch thick blocks of rigid, nontoxic Expanded Polystyrene (EPS) which is comparable to eleven inches of fiberglass batting…and there is no wood  interrupting the insulation.  The dome spherical shape results in 30% less exterior surface area than a conventional house…meaning less walls for heating and cooling to pass through.   The thick uninterrupted insulation and reduced surface area of the dome are two of the main reasons, the Ai dome can save  50% to 60% off conventional box house cooling and heating costs.

American Ingenuity has sold dome kits into 47 states and 14 foreign areas. Ai Domes excel in very hot climates like New Mexico, Arizona, Utah, Texas, Louisiana, Mississippi and Florida or excel in cold climates like South Dakota, Minnesota, Wisconsin, New York, Pennsylvania, etc.

The panel concrete has been especially designed to work in hot or cold climates. Concrete is an excellent and common building material in all temperate zones throughout the world.  The panel concrete is a special formulation containing synthetic fibers and liquid admixtures. 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 (for hot climates), and improve freeze protection.

Ai ship’s synthetic fibers & two liquid admixtures (air entrainment and water reducer) with each Building Kit. These items when mixed with Portland Cement, masonry sand and water produce a dense, rich concrete.   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: is a tougher concrete.  An Assembly Manual is shipped with each dome kit and contains the recipe for the concrete mix.

The following explains why the concrete
on the American Ingenuity Prefab Panel is Crack Resistant.

The American Ingenuity dome has been built in such cold climate states and areas as Canada, Minnesota, South Dakota, Wisconsin, New York, Alaska, Oklahoma. The Ai dome has been built in all the cold climate states other than Rhode Island, New Hampshire and North Dakota.

The Ai panel concrete has been especially designed to work in cold and hot climates. Concrete is an excellent & common building material in all temperate zones throughout the world. Concrete is only affected by freezing temperatures when it is porous & absorbs water. The richness & density of our concrete prevents water absorption that spoils the surface when it freezes. Our concrete is also formulated with an air entrainment admixture that further improves the freeze-thaw characteristics. Although most of the concrete joints will not leak, we don’t depend on the concrete to make the dome watertight. The dome gets additional sealing with a concrete primer & house paint. After the shell is assembled, a concrete primer is used first then two coats of good quality paint is applied. Any porous area that water will penetrate; paint will also soak into and seal. If a leak occurs, the manual explains how to repair with elastomeric caulk or patching compound or tape.

The Concrete Mix recipe includes 5 gal of water, 1 bag Portland (type 1 or 111), 2 ox. Admixture A, 5 oz Admixture B, ¼ large bag fibers, 20 gal. Masonry sand or stucco sand. The panel concrete has been especially designed to work in cold and hot climates. Concrete is only affected by freezing temperatures when it is porous & absorbs water. The richness & density of our concrete prevents water absorption that spoils the surface when it freezes. Our concrete is also formulated with an air entrainment admixture that further improves the freeze-thaw characteristics. The exterior paint is an additional seal to any water that could freeze inside the concrete.

COLD JOINTS – CONCRETE NOT BONDING: The assembly manual that comes with the dome kit explains how to utilize bonding agent and other techniques to join the concrete in the seams. The concrete of the panels also has a ledge to add further bonding surface in the seams. Technology has developed now to prevent cold joints. The concrete seaming of the dome is more effective than spraying concrete onto the entire dome all at once. The concrete on the manufactured panels has time to start curing before the seam concrete is applied. We do not rely on the concrete to seal the dome. Primer and paint is applied to the concrete. (Manual can be shipped after kit order and deposit has been placed).

The same recipe Ai utilizes at our factory to manufacture the panel concrete is given on the plans and in the Assembly Manual. The panel concrete is a special formulation containing synthetic fibers & liquid admixtures. The following is why we ship synthetic fibers and liquid admixtures with our Building Kit. Fibers in concrete work to reduce the formation of shrinkage and cracks in concrete’s plastic state while helping to improve shatter resistance and reduce water migration. These ingredients improve the concrete’s characteristics, create super toughness, extend durability, make concrete impervious to water, give higher tensile & 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 steel mesh and EPS without the need of a bonding agent. We ship the same admixtures and synthetic fibers with the Building Kit so that the concrete mixed on site will have the same properties as the panel concrete. To apply concrete in the seams the temperature should be above freezing, preferably at least 40 degrees. The concrete cannot freeze for two days after the application.

The following is why Ai ships a Bonding Agent with our Building Kit.
• Concrete, or a cement mixture, will not bond to a dry absorbent surface such as dry concrete. The reason is easy to understand when you examine the curing process of cement. When new concrete is applied over old, dry concrete the moisture from the new concrete will be absorbed by the dry concrete especially at the surface where they meet. When the new concrete is robbed of its moisture at the joining surface it will not cure properly and therefore will not bond.

• Bonding agents are designed to improve the adhesion between layers of concrete by acting as a glue and coating and sealing the dry concrete to prevent it from robbing the moisture. The bonding agent that is provided with your kit, when mixed with concrete, also increases its strength.

• To assure that the 2nd layer of concrete placed in the seams on and on the entryways and dormers bonds will with the concrete of the panels:1.) Wet the panels with water and allow them to soak up all the water they will.  2.) Apply bonding agent on the concrete at the edge of the panel and on any concrete that has been placed in the seam. Allow bonding agent to rest per the label before applying fiber concrete.

• There are 2 special features designed into the panel of your kit to improve the bond and strength of your dome.  1.) The panels have a ledge molded into the edge of the concrete where the seam concrete is most needed to bond. This ledge increases the bonding surface, thereby increasing the ultimate strength of the joint.  2.) The steel mesh which extends from the old concrete to the new concrete is a small mesh with compliments the effect of the fibers in securing the joint.

Curing Time: Concrete freezing. The weather and the mix of the concrete (amount of water, etc.) will affect the curing time of the concrete. Usually by the time a complete row of panels are installed and are ready to start the next row, the concrete has cured enough in the first row of panels. However, if place a panel above another panel and cracks start to form in the first coat of concrete, then the concrete has not cured enough. Stop placing panels until the concrete has cured.
