BREATHE GREEN DOME
SPECIFICATIONS- 700 sq/ft greenhouse 30 x20 dome.
- This unique design has a 4' sunken floor level without a separate foundation, usually a footer and a stem wall. This means you can take it apart and move it, and save money.
- With the floor below grade the green house is easier to heat and cool.
- Steel frame and redwood plates.
- Choice of coverings from film, polycarbonate or glass.
- Cold weather growing package, featuring a pressurized inner envelope with hi-tech IR/AC film and high efficiency blower.
- The dome shape makes it extremely wind resistant.

Earth Sheltering/Green House
The benefits of earth sheltering are numerous. They include taking advantage of the earth as a thermal mass, offering extra protection from the natural elements, energy savings, providing substantial privacy, efficient use of land in urban settings, shelters have low maintenance requirements, and earth sheltering commonly takes advantage of passive solar building design.
The Earth's mass absorbs and retains heat. Over time, this heat is released to surrounding areas, such as an earth shelter. Because of the high density of the earth, change in the earth’s temperature occurs slowly. This is known as ‘thermal lag.’ Because of this principle, the earth provides a fairly constant temperature for the underground shelters, even when the outdoor temperature undergoes great fluctuation. In most of the United States, the average temperature of the earth once below the frost line is between 55 and 57 degrees Fahrenheit (13 to 14 degrees Celsius). Frost line depths vary from region to region. In the USA frost lines can range from roughly 20 inches to more than 40 inches. Thus, at the base of a deep earth berm, the house is heated against an exterior temperature gradient of perhaps ten to fifteen degrees, instead of against a steeper temperature grade where air is on the outside of the wall instead of earth. During the summer, the temperature gradient helps to cool the house.

The Breathe Green Dome can be bermed 48 inches without a permanate concrete footprint. This uinique system uses recycled lumber wraps, vapour barrier and 1 inch foam sheets.
The dome can be bermed 8' feet high usually to the north side. This requires additional #4 rebar which has to be welded.
