Definition

Sustainable architecture refers to the design, construction, and operation of buildings in ways that minimize environmental impact, optimize resource efficiency, and promote occupant well-being. It integrates ecological principles with architectural practice to create structures that are environmentally responsible and resource-efficient throughout their lifecycle.
