Small Bermed House Plans: Essential Considerations

Small bermed house plans offer a unique and sustainable approach to home design, providing energy efficiency, thermal comfort, and a connection to nature. When considering a bermed house, it's crucial to understand the essential aspects that make these homes distinctive.

Berming: The Foundation of Thermal Performance

The defining feature of a bermed house is the earthen berm that surrounds its exterior walls. This berm insulates the home, reducing heat loss during the winter and heat gain during the summer. The earth's thermal mass absorbs and releases heat slowly, creating a more stable indoor temperature.

The placement and dimensions of the berm are critical. North-facing berms provide maximum shade in summer and minimize heat gain. The height and angle of the berm should allow for proper drainage and prevent moisture accumulation.

Energy Efficiency and Sustainability

Bermed houses inherently reduce energy consumption. The berm's insulation lowers heating and cooling requirements. Combined with energy-efficient windows, insulation, and renewable energy sources such as solar panels, bermed homes can achieve significant energy savings.

Additionally, earthen materials have a low carbon footprint and contribute to a sustainable built environment. The use of local materials further reduces transportation impacts.

Thermal Comfort and Natural Ventilation

The thermal mass of the berm creates a comfortable indoor environment. During warm weather, the berm absorbs heat, cooling the interior. In cold weather, it releases heat, providing warmth. Bermed homes often incorporate passive solar design, utilizing windows and clerestories to capture sunlight and reduce reliance on artificial lighting.

Natural ventilation is promoted through strategic window placement and the use of thermal chimneys. The berm can channel cool air into the house during summer and extract warm air during winter, enhancing air quality and reducing energy costs.

Site Selection and Drainage

The site selection for a bermed house is crucial. The terrain should have a gentle slope to allow for proper berming. Adequate drainage is essential to prevent water damage to the berm and the house. A professional geotechnical engineer should evaluate the site's soil conditions and recommend appropriate drainage measures.

The orientation of the house on the site is also important. North-facing berms are desirable for thermal performance, while east- or west-facing exposures can maximize solar gain for passive heating.

Structural Integrity and Durability

The structural integrity of bermed houses is paramount. The weight of the berm must be properly supported by the foundation and walls of the house. Engineers typically design reinforced concrete or masonry foundations to withstand the lateral pressure of the berm.

The materials used for the exterior walls, such as concrete, stone, or rammed earth, should be durable and able to withstand moisture. Proper waterproofing and drainage systems are essential to prevent water penetration and protect the structural integrity of the house.

Design Considerations and Aesthetics

Beyond technical considerations, small bermed house plans also offer unique design opportunities. The berm can be integrated into the landscape, creating a seamless connection between the house and its surroundings.

The exposed portions of the house, such as windows, doors, and roofs, can be designed to reflect the local architecture and aesthetic preferences. Natural materials, such as wood, stone, and earthen plasters, complement the berm's natural appearance and create a warm and inviting ambiance.

By carefully considering the essential aspects outlined above, you can create a small bermed house that is energy-efficient, thermally comfortable, sustainable, and aesthetically pleasing. Embracing the unique features of bermed architecture offers a path to a harmonious and environmentally conscious home.
