This document discusses a study comparing green buildings to conventional buildings. It finds that green buildings are more energy efficient, have lower operating and maintenance costs, provide improved occupant comfort and health, and have a lower environmental impact over their lifecycle compared to conventional buildings. The study establishes an integrated construction process to help partners successfully implement green building practices and technologies during project development. Key benefits of green buildings identified include reduced energy and water usage, lower greenhouse gas emissions, less construction waste, and protection of natural habitats and wildlife.
