It involves considering ecological context and principles in the design process to create harmonious products, buildings, landscapes, and systems. Key principles of ecological design include life cycle assessment, biophilia, resource efficiency, regenerative design, passive design, biomimicry, low-impact materials, design for adaptation, community engagement, and systems thinking.
