Biophilic Design In the Built Environment: Trends, Gaps, and Future Directions

This comprehensive review analyzes 435 peer-reviewed studies on biophilic design, offering the most detailed synthesis to date of how nature-integrated architecture impacts human health, well-being, and cognitive performance. Using a hybrid methodology of bibliometric mapping and structured content analysis, the authors identify key trends, gaps, and future directions in the field.

Key Findings:
– Most studies focus on institutional buildings—workplaces, schools, and healthcare facilities—using surveys and experiments.
– Residential, retail, transit, and correctional facilities are rarely studied.
– Older adults, neurodiverse individuals, and marginalized communities are underrepresented.
– Greenery, daylight, and sensory experiences dominate research; psychological parameters are overlooked.
– Only 56 studies mention climate, and just 15 address cultural context.
– Advanced tools like AI, VR, and biometric sensors are rarely used.

Future Directions:
– Develop climate-responsive and culturally grounded biophilic frameworks.
– Expand research into neglected building types and vulnerable populations.
– Integrate neuroscience and biometric tools to empirically measure design impact.
– Foster global collaboration to standardize biophilic design metrics and policy integration.

This paper is a must-read for architects, designers, researchers, and policymakers seeking to advance biophilic design as a human-centered, evidence-based strategy for healthier built environments.
