Sustainable architecture is a design approach that focuses on creating buildings that are environmentally friendly and resource-efficient. This includes using materials that are renewable, reducing energy consumption, and minimizing waste throughout the building's lifecycle. The goal is to create structures that have a minimal impact on the environment while providing a healthy living space for occupants. Key principles of sustainable architecture include energy efficiency, water conservation, and the use of sustainable materials. Techniques such as passive solar design, green roofs, and rainwater harvesting are often employed. By prioritizing these practices, architects aim to contribute to a more sustainable future for our planet.
