One unique feature that geodesic dome homes are known for are their amazing insulation properties. With a design that focuses on retaining heat within the structure, these buildings are inherently energy-efficient. Their unique shape is key to this efficiency, minimizing heat loss and gain, while enhancing airflow.
As a result of this unique structure, you depend on artificial heating and cooling less. When combined with energy-efficient materials, dome homes’ natural insulation properties get a serious boost. The use of Insulating Concrete Forms (ICFs), concrete walls poured between two layers of polystyrene insulation, is becoming a popular choice among builders, creating an airtight, strong envelope.
This can reduce heating and cooling energy use by more than 75%. Turtle Island’s dome shape minimizes the overuse of resources, requiring 30% fewer materials than conventionally constructed buildings. Yet, a kit is necessary in order to prevent material waste while making triangles from larger shapes.
Dome structures have even more perks, such as interesting acoustics and weathering resistance. A dome left outside in a humid tropical forest for over 12 years had no detectable leaks. In comparison, a conventional roof might require an entire tear off.
Typical insulation materials found in dome construction are fiberglass and foam, making sure energy is used efficiently. As one example, a friend who lives in Florida says she’s hardly used air conditioning in her monolithic dome home this summer.
Passive Solar Heating
Geodesic dome homes have a distinctive structure that provides maximum exposure to the sun, boosting the effects of passive solar heating. Its unique, rounded surface absorbs sunlight from all angles, giving it the perfect shape for collecting solar energy. This smart design feature allows you to soak up a good chunk of your home heating needs straight from the sun.
Deep overhangs, large windows and skylights all serve to maximize passive solar gain. With them installed, you allow sunlight to pour into your home, warming the interior without any extra effort. This configuration can reduce your heating and cooling expenses by a minimum of 60 to 70 percent.
The strategic placement of the dome is important for heating efficiency in all seasons. In a perfect world, placing the dome with the long end facing south will offer the greatest sun exposure during winter months. The house’s structure, with thick concrete slabs insulated by polyurethane foam, acts as a massive thermal flywheel, efficiently storing heat.
Here’s how dome homes support passive solar heating:
-
Large windows and skylights for ample light.
-
Thick concrete floors with dark tiles to absorb and hold solar heat.
-
Insulation with polyurethane foam to retain warmth.
-
An open solaratrium to the outside air.
A 41,000-Btu electric furnace serves as supplemental heat, operating for short bursts during cold winter mornings.
Air Circulation and Ventilation
The distinctive spherical design of geodesic dome homes encourages a natural flow of air circulation. The curved surface lets air slip cleanly around the structure, limiting stagnation and improving air circulation. This design ensures a consistently comfortable environment by maintaining air circulation and evenly distributing heat.
Strategically placed air vents help to ensure this air exchange continues. With careful placement of the vents, dome homes allow ambient air to actively flow in and out, pulling in fresh air while pushing old, stale air out naturally. Solar-powered exhaust fans placed in round portals are designed to actively push hot air out.
Meanwhile, zippered roof screens let warm air escape from the top, providing a crisp and renewing cooling exchange. Open floor plans are another big factor that helps airflow in dome homes. Having less walls and barriers allows air to flow more easily throughout the space, keeping their indoor environment comfortable year-round.
This integrated design works hand in hand with cooling systems, such as mini-splits, that provide the ability to control temperature in different zones. It’s no surprise that most dome owners use mini-split systems for heating and cooling, comfortably enjoying their domes year-round.
Optimizing air circulation in geodesic dome homes involves several strategies:
-
Install solar fans for effective hot air removal.
-
Use portable evaporative coolers and mini-split systems.
-
Utilize strategically placed vents and roof screens.
-
Ensure proper insulation, doors, and windows for energy efficiency.
Light Utilization
Geodesic dome homes take advantage of natural light due to their shape. These lattices are made up of interlocking truss-like triangles or hexagons. They provide a distinctive look by creating an open, airy space that lets sunshine pour in.
Fully transparent domes perform best in environments where natural light is the primary light source. They do wonders improving light quality and reducing energy use in art studios and hobby rooms. The design team’s use of custom triangle skylights and large windows creates this effect, letting in enough natural light to help the school feel bright and welcoming.
Purposeful light utilization can help to significantly minimize the need for artificial lighting. In turn, you’ll save energy and build a more sustainable home.
To enhance light utilization in dome interiors, consider these practical steps:
-
Install reflective surfaces to bounce light around the room.
-
Use light-colored interior finishes to maximize brightness.
-
Place furniture strategically to avoid blocking windows.
-
Incorporate indoor plants that thrive in natural light.
-
Choose open layout designs to let natural light travel through spaces.
Surprisingly, a well-lit dome home can also be a colorful home, leading to a lively environment that complements the savings on electricity bills. This intelligent utilization of light is exactly what geodesic domes are centered around, first developed by Walter Bauersfeld.
Even today, it influences contemporary architectural designs like Hypedome’s hexagonal dome.
Energy-Efficient Materials
No matter what materials you use to construct a geodesic dome home, selecting energy-efficient materials is essential. These energy-efficient materials improve the sustainability of the dome’s already-natural efficiency. A brilliant case in point would be Fisiterm, an insulation layer of polyester fibers. This material has proven very popular at EcoCamp.
This material provides thermal mass, which helps keep indoor temperatures stable so you aren’t always heating or cooling your home. Dome construction places an emphasis on the use of energy-efficient building materials such as recycled steel and bamboo. These materials provide a massive boost in thermal performance.
The spherical shape of geodesic domes are great for circulating air and energy in an efficient and effective way. This characteristic ensures their suitability even for harsh climates, like Patagonia. For example, homeowners in Florida sometimes benefit from homegrown, energy-efficient materials.
As a result, they hardly ever have to use air conditioning. With the ability to construct the dome using 30% fewer materials, the structure’s environmental impact is positively affected. Unless you’re using a pre-designed kit, this benefit can be offset by material wastage.
Here’s a list of recommended energy-efficient materials for dome construction:
