Biophilic design is known to elicit mental and physical health benefits, as stated by the authors on page 1, lines 29-32.
P1, L39-41: Please provide references to these frameworks. Reading further to page 3, I believe these are the 24 biophilic design attributes [ref. 25,39], and the 14 patterns of biophilic design [ref.40]. Further references around the biophilic concept could also be provided, e.g.: Bjørn et al., 2009. Biophilia: Does Visual Contact with Nature Impact on Health and Well-Being? International Journal of Environmental Research and Public Health. Ulrich, 1993. Biophilia, biophobia, and natural landscapes. Ko et al., 2020. A window view quality assessment framework. LEUKOS. The latter reference reviewed many international standards that advocate nature and biophilic design for view and building spaces, with examples given to the Singapore context. This somewhat overlaps with my next comment.
