How Does The American Ingenuity Geodesic Dome COMPARE TO THE MONOLITHIC DOME?

Are Aidomes as sturdy as Monolithic domes? Yes, our domes are as sturdy as Monolithic domes and Ai’s has a rigid noncombustible  concrete exterior vs Monolithic Dome has an outer membrane.   To view video of monolithic dome and a fire and info about Ai dome’s fire resistant concrete exterior, click on Ai Concrete Exterior.  The Aidome exterior comes with a 225 mph wind and EF4 Tornado Warranty.  One of Aidomes withstood the impact of a 30″ in diameter hickory tree impact with no damage.  An Aidome withstood Hurricane Andrew and a tornado at the same time with no structural damage – only a hairline crack and small piece of concrete broken when the tornado slammed a two wide steel horse trailer on the dome.  To view  strength info about Aidomes, click on Acts of Nature.   Why did Ai stop guniting concrete on to the exterior of its dome – too labor intensive and a waste of concrete.

The Ai dome exterior walls cost 1/3 to 1/2 less than a Monolithic dome exterior.  Although you have not asked, Aidomes are equally if not more energy efficient. Ai’s dome kit contains seven inch thick insulation which is comparable to eleven inches of fiberglass batting.

The assembly of the monolithic dome requires expensive concrete spraying equipment and is not a do-it-yourself project. The American Ingenuity Dome Kits were specifically designed for the owner builder. All of the panels are premarked with numbers and letters which are described in the Assembly Manual and on the Nomenclature Blueprint in the Building Plans.  Ai’s dome kits can be assembled using a mortar mixer, conventional cranes, man lift or hoisting mechanisms with no need to spray concrete over the entire dome surface. The Ai component panels already have 80% of the exterior prefinished concrete reinforced with galvanized steel mesh and fibers on the exterior. The Aidome kit requires less on site concrete work because it is only the seam areas between the component panels and the entryways and dormers which require concreting. The seam area between the panels is about 5” wide and 3” deep with the on site seam concrete application averaging two inches thick.  To view info about being an owner builder, click on DIY.

In 1976 American Ingenuity built its first geodesic dome utilizing reinforced concrete over expanded bead polystyrene (E.P.S.) insulation. Road mesh was hand tied onto propped up E.P.S. panels, the concrete was then gunited or pumped over the propped up E.P.S. insulation. Each time Ai built a dome this way, we knew there had to be a better way resulting in a prefabricated component panel being invented and receiving a patent.  Countless designs and manufacturing construction techniques were analyzed in the early years as Ai developed a new generation in dome housing. Ai has outgrown two previous models as we progressed to a five dome office and factory complex.

Spraying concrete on a structure causes a waste of labor and concrete. The concrete ends up being 2″ thick in one place and 3″ to 4″ thick in other places. The concrete on the Ai geodesic dome needs to be thick only in the seams and thin on the panels.  It is a waste of labor because it is difficult for the concrete finishers to finish the concrete as it is curing. Also a continuous sprayed concrete structure will cause the concrete to cure all at once.  Preconcreted panels allow for the panel concrete to cure prior to the seam concrete being applied.  For those homeowners who do not want to assemble the American Ingenuity dome kit themselves, the homeowner can hire a local builder who hires the independent kit assembly consultant to supervise the builder’s workers during the kit assembly.  To view our web site info about the Specialist/Consultant, please click on Specialist.

THERMAL MASS IN RELATION  TO MONOLITHIC DOMES

Generally speaking, in a home, thermal mass is the amount of stuff inside the house that retains heat. Although thermal mass accounts for the fact that some things have a greater “thermal capacity” to store heat than others, to understand its effect you can think of it as the total weight of everything contained in the house. With more thermal mass (heavy stuff) inside your house more heat will have to be added or removed to change the temperature. Expressed another way, if heat is not being added the temperature will be slower to change. Does Thermal Mass affect the energy efficiency of the house? NO.  As heat in the house is lost through walls, windows etc, the temperature drops.

The thermal mass releases (loans) heat into the house slowing down the temperature change. When the heating system turns on it must replace heat lost to the outside and it must also replace (pay back) the heat given off by the thermal mass. There is no long-term gain or loss; all of the heat given off by the thermal mass must be replaced. The amount of heat required to maintain the temperature inside a house is solely dependent on the amount of heat that escapes to the outside. All houses have walls, floors, and usually fixtures, appliances and stuff that will retain heat. A large amount of thermal mass can cause long on/off cycles of the heating system when shorter cycles would stir the air more frequently providing more comfort and uniform temperatures inside.

The recent generation of thermostats are a proven money saver by lowering the inside temperature (which lowers the heat loss to the outside) during those hours you are away at work, etc.  A large thermal mass makes it much harder to change the temperature; therefore reducing the savings.

Why is the Ai dome so energy efficient?  

Ai’s kit has standard 7″ thick EPS R28 insulation. The cost to build one of our kits runs about the same to build as a traditional home but our home has insulation comparable to 11” of fiberglass batting!  (using the 7″ EPS).  A traditional house would require 2×10 to come close to our dome….but it would have wood interrupting the insulation.  The thick insulation, reduced exterior surface area (30% less surface area than conventional shaped home) and uninterrupted insulation causes low cooling and low heating bills.

As far as functioning in cold, snowy environment, American Ingenuity domes have been built in such cold climates as Canada, at 7,500 feet elevation in Utah, 3,400 feet elevation in North Carolina, South Dakota, Minnesota, Montana, Wisconsin, Vermont, New York and all cold states in the USA except for New Hampshire, Rhode Island and North Dakota.  It is easier to heat an Ai dome that to cool one. To heat the furnace does not need to overcome heat generated from sunlight, clothes dryer, dish washer, body heat, light fixtures.

Below are examples of heating and cooling info on Aidomes.

  1. To view Glenda’s 1,075 sq. ft. dome home’s electric bill please view 34′ Dome Home Energy Recap   (total electric house with solar hot water panel – has actual copies of the electric bills).  I can cool my 1,075 sq.ft house for less than $27 a month in the hot Florida summer months.  (76 degrees when home and 79 degrees when not). As we discussed the Ai dome is even easier to heat than to cool.  To Heat you do not have to overcome sunlight, heat generated by the clothes dryer, dishwasher, computer, etc. This generated heat is utilized.
  2. Ai’s dome offices of 3,700 sq.ft. can be cooled for less than $85 a month (you can view actual electric bills at this link) in the hot Florida summer months to 74 degrees during the day Mon-Sat and 77 degrees at night and on Sunday.
  3. One of our domes built in South Carolina received the Energy Star  It has geothermal pipes.  Home Energy Partners certified his home used 61% less energy than in comparably-size housing.   The dome owner installed a geothermal cooling & heating system. To view pictures & info about his geothermal system, click on System.  Klaus’s total monthly average energy bill was $49. This includes the electricity and propane costs for his entire 1,600 sq.ft. – 40 ft. dome.
  4. Here is a quote from the Charles family about their PA 40 dome on full basement with Geothermal and radiant floor heating:  Mr. & Mrs. Charles: ““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.”
  5. Jim Collar’s Utah Ai concrete dome buildings (45 linked to a 30’) operate off the grid by using photovoltaics’, masonry heater fireplace and passive solar water tubes. To learn more, click on  Off The Grid.
  6. Per Eric Brindley, “Our 2,600 sq.ft. 48’ dome located in Edgewater Florida 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.”
  7. If a person does not need to air condition their home, then if window dormers or windows within entryways are placed opposite each other cross ventilation can occur and cool the dome.  Our factory has three Ai domes which are not air conditioned.  In the heat of the Florida summers, you can walk in the domes and they are cooler than the outside air.  Floor fans circulate the air.  The super insulated dome is cooler inside with no air conditioning than a conventional house.
  8. Glenda owned a 34’ dome built at 3,400 feet elevation that could reach -8 degrees in the winter. Its south facing high profile entryway allowed sunlight to come in the dome.  When we wanted to carry wood and burn the fireplace, the fireplace and the sunlight from the entryway was enough to heat the dome.  At night we utilized a kerosene feed heater set at 68 degrees and the fire place for heat. During the winter we would use around 100 gallons of kerosene.
  9. Yes a fireplace can be installed in the dome.  Just let us know about where you want it located and our CAD department with use its 3D elevation view to locate the flue pipe’s exit from the dome.  It needs to be 8” from the center of a seam. On site a hole can be cut in the prefab panel.  Instructions on how to cut the hole are in the Assembly Manual.
