Objects: The purpose of the research is to obtain a general viewpoint ofthe quantity and frequency of visual factors in residential facades inTehran, which have neurological effects on the viewer.Methods: The applied study was done with the quantitative method andthrough field study with photography. The images were prepared basedon the criteria, extracted from the background of the research. Allimages were quantitatively evaluated, and statistical analyzes based onimages were performed in Excel and SPSS software.Findings: Investigating the sources related to design with a neuroarchitecturalapproach shows that these five factors include: daylight(level of opening), color combination (light and dark color), geometry(curved lines), complexity, and vegetation are more effective than othervisual factors in enhancing the wellbeing of the residents in a building.Conclusion: Among the mentioned factors, "vegetation" with afrequency (of ۲.۶%) and "curved lines" with a frequency (of ۷%) areamong the least ranked factors in the residential façade buildings inTehran. This result emphasizes the necessity of paying attention to theuse of vegetation and curved lines in new building designs.
