A "green" design is a building plan that intentionally makes use of natural materials, according to BusinessDictionary.com. The goal is to minimize the use of non-recyclable building materials that clog landfills, replacing them with natural resources that are biodegradable and reusable.
The Environmental Protection Agency indicates on its website that many manufacturers have developed natural alternatives to synthetic building materials. Natural wood, cellulose, recycled cotton and steel are common examples of recyclable materials used in "green" building designs. Homeowners often prefer a "green" design to satisfy their personal passion for the environment. Companies use "green" designs to enhance their public image.
