For green building standards, LEED from USA and BREEAM from UK recently have been finding global
acceptance while several new green building definitions based on local needs emerged in different
parts of the globe.
U.S. LEED standard for green buildings developed a rating system based on the following main categories:
» Energy and Atmosphere: Energy efficiency and renewable energy
» Sustainable Sites
» Water Efficiency
» Materials and Resources
» Indoor environmental quality
In addition to five mandatory categories, innovation and design process of the building and regional priority
are the two optional areas considered for additional points.
Regional LEED certification systems have been launched whereas a green building standard targeting
global application is under way.
