A natural building involves a range of building systems and materials that place major emphasis on sustainability. Ways of achieving sustainability through natural building focus on durability and the use of minimally processed, plentiful or renewable resources, as introduction to building construction pdf as those that, while recycled or salvaged, produce healthy living environments and maintain indoor air quality.


Natural building tends to rely on human labor, more than technology. The basis of natural building is the need to lessen the environmental impact of buildings and other supporting systems, without sacrificing comfort or health.

To be more sustainable, natural building uses primarily abundantly available, renewable, reused or recycled materials. The use of rapidly renewable materials is increasingly a focus. In addition to relying on natural building materials, the emphasis on the architectural design is heightened.

The orientation of a building, the utilization of local climate and site conditions, the emphasis on natural ventilation through design, fundamentally lessen operational costs and positively impact the environmental. Building compactly and minimizing the ecological footprint is common, as are on-site handling of energy acquisition, on-site water capture, alternate sewage treatment and water reuse. The materials common to many types of natural building are clay and sand.

Other materials are avoided by practitioners of this building approach, due to their major negative environmental or health impacts. Many traditional techniques and materials are now experiencing a resurgence of popularity.

This differs around the world based on climate appropriate building design and the availability of local materials. One of the oldest building methods, adobe is simply clay and sand mixed with water. Often, chopped straw or other fibers are added for strength.

The mixture is then allowed to dry in the desired shape. Usually adobe is shaped into bricks that can be stacked to form walls.
