Green building, also known as sustainable building, is the practice of designing and constructing buildings that are environmentally responsible and resource-efficient throughout their entire lifecycle.

Green building promotes wellness by creating indoor environments that are healthier and more comfortable for occupants. This includes improving indoor air quality, providing access to natural light and outdoor views, and using materials that are free from harmful chemicals.

Some features of a green building may include energy-efficient lighting and HVAC systems, water-saving plumbing fixtures, the use of renewable energy sources, and the use of sustainable building materials such as bamboo and recycled content materials.

Green building can benefit the environment by reducing the amount of energy and resources used in the construction and operation of buildings, as well as reducing greenhouse gas emissions and other pollutants. This can help to mitigate the impacts of climate change and preserve natural resources for future generations.

Examples of green buildings include the Bullitt Center in Seattle, which is a net-zero energy building that generates all of its own energy on-site, and the Bank of America Tower in New York City, which uses a combination of energy-saving technologies to reduce energy consumption by 50% compared to a typical office building.
