In-text citation in Page 1 Line 44: “Some scholars summarized and classified the natural design features into biophilic design frameworks to guide design activities [25, 39, 40, 50, 51, 52].” Three references are added in the References List: Ulrich, 1993. Biophilia, biophobia, and natural landscapes. The Biophilia hypothesis. USA: Island Press: Washington, D.C. Bjørn et al., 2009. Biophilia: Does Visual Contact with Nature Impact on Health and Well-Being? International Journal of Environmental Research and Public Health. 6, 2332-2343. Ko et al., 2021.

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.
