Earth Bermed Passive Solar House Plans

Earth Bermed Passive Solar House Plans: Essential Aspects

Earth bermed passive solar house plans are designed to maximize energy efficiency and provide a comfortable living environment. Here are the essential aspects of these plans:

Site Orientation

The orientation of the house on the site is crucial. The long axis of the house should be oriented towards the equator to maximize solar gain. This ensures that the south-facing wall receives the most sunlight, especially during the winter months.

Earth Berming

Berming is the process of partially burying the house in the earth. This provides insulation and thermal mass, helping to regulate the indoor temperature. The berm should be on the north side of the house, where it will block cold winds and minimize heat loss.

Windows and Glazing

Windows play a significant role in passive solar design. The south-facing windows should be large and well-insulated to maximize heat gain. Overhangs or shading devices can be used to prevent overheating during the summer months.

Thermal Mass

Thermal mass is any material that can absorb and release heat. In earth bermed passive solar houses, the earth berm and the interior walls and floor act as thermal mass. This helps to moderate the indoor temperature by absorbing heat during the day and releasing it at night.

Insulation

Insulation is essential for minimizing heat loss. The walls, roof, and floor should be well-insulated to prevent heat from escaping in the winter and entering in the summer. The type of insulation used should be appropriate for the climate and soil conditions.

Indoor Air Quality

Earth bermed passive solar houses can have excellent indoor air quality due to the natural ventilation and the absence of moisture problems. The earth berm helps to filter out pollutants and allergens, and the use of natural materials promotes a healthy indoor environment.

Other Considerations

In addition to the essential aspects mentioned above, other considerations for earth bermed passive solar house plans include:

The type of soil on the site
The drainage system
The landscaping around the house
The long-term maintenance and operating costs

By carefully considering these factors, architects and homeowners can design and build energy-efficient and comfortable earth bermed passive solar houses that provide a sustainable and healthy living environment.
