Which strategy of Biophilic Design involves the use of natural materials?

The strategy of Biophilic Design that involves the use of natural materials is indeed focused on integrating elements that are directly sourced from nature into the built environment. This approach emphasizes incorporating materials that have not been heavily processed or altered, allowing the qualities and textures of these natural substances to resonate with occupants. By using natural materials, spaces can evoke a sense of connection to the outdoors, fostering emotional well-being and promoting a healthier environment for users.

This strategy is distinct from others in Biophilic Design; for example, the use of "Direct Nature" refers to the incorporation of actual elements like plants or water features, while "Evoking Nature" might involve visual representations or patterns that mimic natural forms. "Spirit of Place" pertains to creating an environment that reflects the local culture and characteristics distinctive to a specific area rather than focusing purely on the materials themselves.
