Natural buildings are buildings that are made of natural, renewable and reclaimed materials. These buildiing are generally designed archetecturaly to be ecologically beneficial. The orientation (which way it faces toward the sun) and location of the buildings are considered in terms of what would be the most effecient. There is an emphasis on natural ventilation through design which lessens bills and positively impacts the environment. Minimizing the ecological footprint is common, as is on-site renewable energy collection, on-site water catchments, alternate sewage treatment and water reuse.
