Green buildings are designed to reduce environmental impact through efficient use of resources, protection of occupant health, and reduction of waste and pollution. They emphasize using renewable resources and techniques like passive solar, green roofs, and permeable surfaces. The Indian Green Building Council promotes green building practices in India and has developed rating systems to evaluate buildings. Notable green building projects in India include the ITC Green Centre in Gurgaon and Nokia's corporate office, which have received LEED Platinum certification.
