The concepts about green architecture can generally be organized into several areas of application. These areas include sustainability, materials, energy efficiency, land use, and waste reduction. Sustainability Green buildings are not only be designed for a present use, but consideration is also be given to future uses as well. If specific technical issues prevent use of the building for a new function, then the materials used in its construction are designed to facilitate ease of recycling and reprocessing of materials. Materials Buildings consume a variety of materials in their construction.
Green design reduces the dependence on resource intensive products and materials.
Today, there are an increasing number of products available made from efficient, earth-friendly, or recycled materials. In a green building, consideration is also given to the construction process itself. Materials that minimize waste or can be recycled, help contribute to an efficient and environmentally sensitive construction process. Another important aspect of green design is the integration of energy efficient mechanical systems and conservation methods. Green buildings are designed to reduce or eliminate the dependence on fossil fuels.
