This study is conducted to determine the weights of biophilic design parameters created by empirical experiments in the literature and the effects of the human-space-nature relationship in human psychology, due to the recent COVID-19 pandemic that the whole world has been exposed to. It is aimed to calculate the weights of biophilic design parameters, that are discussed under 3 main headings and 14 basic parameters in the literature by using the SWARA method, which is used to determine criteria weights in decision making and performance evaluation processes. Accordingly, a survey has been conducted on 40 national and international architects working for both academic and non-academic environments. The survey results are used in the SWARA method and the weights of the biophilic design parameters are determined. According to the results obtained, prospect (wide panorama), visual connection with the nature and connection with the natural system parameters and processes are determined as the most important design parameters to determine the effects of human-space-nature relationship in human psychology. It is also aimed to use these results in further studies to establish and to develop the concepts like "Biophilic Footprint" or "Biophilic Efficiency Coefficient" in the architectural literature.
