A Green Building is a structure designed, constructed, and operated to minimize its environmental impact and enhance sustainability. These buildings focus on energy efficiency, resource conservation (like water and materials), and improving indoor environmental quality. Green buildings often incorporate renewable energy, eco-friendly materials, and efficient waste management practices, while also promoting the health and well-being of occupants.

In summary, a green building aims to reduce its carbon footprint, conserve resources, and provide a healthier living or working environment, all while being economically viable.
