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.

SYI, 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.

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.

Although the test was conducted in a temperate locale (Florida) without summer and winter temperature extremes, the American Ingenuity dome out performed the other structures. In the summer, the energy savings for the dome exceeded 36% and during the winter, the energy savings exceeded 42%. In areas of severe cold and heat, savings would be expected to be considerably higher.

Also, the blower door test showed the dome to be 56% tighter than the conventional test structure and 29% tighter than the Dow house.

To see if air was passing through walls of the dome, tests using infrared were performed. Thermal irregularities in the dome were shown to be insignificant.

Some of the reasons for the American Ingenuity’s Dome’s super energy efficiency are:

  • Super insulation that does not degrade with time, moisture, or compaction.

  • Spherical shape means reduced exposed surface.

  • Airtight exterior virtually eliminates energy leakage.

  • Solid thermal envelope.

  • Uniform R-value. The insulation is not interrupted with structural members (e.g. 2×4 roof trusses). The only breaks are for doors and windows.

  • Downsized heat and air equipment.

The American Ingenuity Dome kit comes with lifetime R-28 Expanded Bead Polystyrene Insulation (E.P.S.), or if you choose, thicker R-36 E.P.S. insulation is available. In cold climates, you may find that a single ventilating wood stove will provide all the heat your 22′ – 30′ in diameter dome home may need.  Larger square footage domes (34′, 36′, 40′, 45′, 48′) need a ductless or ducted system where the heated or cooled air can be distributed evenly throughout the dome.  Heat recovery ventilators or exhaust fans remove interior water vapor from the dome.  The air conditioner or furnace will be one third smaller than is needed for the same square footage conventional house.

Insulation Comparisons:

  • 2×4 solid wood with 3 1/2″ fiberglass is about R-8

  • 8″ Concrete Block, with 3/4″ air, 3/4″ Celotex is about R-9

  • 2×6 Solid wood construction with 5 1/2″ fiberglass is about R-11

  • 2×4 solid wood with 3″ urethane is about R-13

  • 7″ E.P.S. insulation is R-28 (standard insulation with the Ai dome kit) is comparabel to 11″ of fiberglass batting.

  • 9″ E.P.S. insulation is R-36 (you can order this thicker insulation for colder climates.)

Have the AiDomes won energy efficiency awards?

  • Yes, our first office dome (40′ and 30′ garage) built in 1986 won the Aurora Award for Most Energy Efficient Home in the Southeastern United States and the Aurora Grand Award for the Most Energy Efficient Structure. This dome with standard R-28 insulation beat a passive solar home designed and built by Florida Power & Light, a nuclear powered Florida Utility Company.

Insulated Concrete Form Buildings Save Energy*

A study, conducted by Dr. Pieter VanderWerf of the Boston School of Management and sponsored by the Portland Cement Association, revealed that homes built with insulating concrete forms (ICFs) consume, on average, 44% less energy to heat and 32% less energy to cool than conventional wood-frame homes.  (Ai’s dome has 30% less surface area than a conventional shaped house and the insulating concrete panels are not interrupted by wood, as a result the Ai dome gives a 50% to 60% reduction in heating and cooling costs versus a conventional box shaped house heating and cooling bills.)

The study analyzed statistics from 29 ICF homes and 29 wood-frame homes. All of the homes were less than six years old. “We wanted to approach this study as an ‘apples to apples’ comparison,” said VanderWerf, “so we paired each ICF house with a comparable frame house.”

The paired houses were located near each other and were of similar square footage. VanderWerf adjusted the energy consumption of each house to account for differences in size, design, foundation, number of occupants, thermostat setting and HVAC equipment. “We tentatively concluded that these rates of savings should be fairly constant, regardless of location (or local climate),” said VanderWerf.

Although most of the homeowners participating in the study liked there dwellings, regardless of the type of construction, the reasons they gave for their satisfaction were quite different. The ICF homeowners most often cited functional advantages, such as comfort (including evenness of temperature and low air infiltration), sound reduction, energy efficiency, solidity and strength. Several ICF homeowners said they liked their low utility bills. Owners of the wood-frame homes most often cited advantages unrelated to the home’s quality of construction, such as location, floor plan and inclusion of the owner’s preferred features. VanderWerf added that “not many of the owners of frame homes considered it superior construction.”

Superior construction is one of the main reasons for the continuing upsurge of ICF construction in North America over the past several years. PCA market researchers report that in 1994, only 0.1% of new home construction (1,110 homes) was built using ICF. But, researchers predict that by 2000, nearly 7% of all homes built in the country (about 68,000 homes) will use ICF construction.
