A green building is a structure that is designed, built and operated with an emphasis on energy efficiency, environmental sustainability and occupant comfort. The goal of a green building is to minimize its impact on the environment while maximizing its benefits for the people who use it. This can be achieved through various means such as using eco-friendly materials, reducing water consumption, utilizing renewable energy sources, improving indoor air quality and incorporating sustainable design practices throughout the building process. Green buildings are also designed to reduce waste, conserve resources and promote a healthier environment for everyone involved.
