The Ai dome is ideal for a vacation home for several reasons:

Unique design that results in a fun home to visit and possibly rent out when not home.

Dome can nestle into a wooded setting without concern of a tree impact or that a forest fire will burn the concrete exterior. See Ai’s  tree impact link for info about 30” in diameter hickory tree falling on dome with dome suffering no damage. The concrete dome exterior is noncombustible so exterior is fire resistant. As a matter of fact all the materials in the dome prefab panel are noncombustible (concrete, galvanized steel, EPS and ½” Drywall by Georgia Pacific.

Super energy efficiency: The 7” Eps insulation is comparable to 11” of fiberglass batting and is not interrupted by wood. The dome walls and roof have 30% less surface area than a conventional house; expect heating and cooling costs to be 50% to 60% less than conventional housing. As a result during winter time, when you are not visiting your vacation dome, the dome requires very little heat to keep the water pipes from freezing.

During the winter this dome is heated with a heater fueled by kerosene. The dome is located at 3,400 feet elevation in North Carolina. When not occupied the heater is kept at 48 degrees. Last winter of 2014/2015 the dome was not occupied and used 100 gallons of kerosene to heat the dome…heating costs were around $350.

When the dome is occupied in the winter, a wood burning fireplace and the sun from the south facing entryway heat the dome during the day. At night the heater is set at 65 degrees and keeps the dome snug.  Heating costs for dome in winter when occupied is around $450.

Low Exterior Maintenance: The Ai dome has less exterior maintenance than a conventional framed house. The dome’s exterior is a shell of continuous concrete with incredible durability with nothing to rot, rust, warp, be eaten by termites. The exterior concrete is primed and painted with no shingles or separate roofing to blow off in high winds and no shingles to burn. Normal maintenance is to pressure wash and paint every 4-6 years. The dome’s expanded polystyrene insulation will not shrink, deteriorate, absorb moisture or relinquish its R-value.  To view a summary of advantages, click on Advantages.
