Abstract Numerous studies have shown the importance of windows in architecture and their healing effect through external views. This study shares the same purpose but focuses on overall electroencephalogram (EEG) changes to derive tendencies and suggest design guidance, rather than relying on specific indicators based on window conditions in a small-sized room. Additionally, it examines the impact of images installed instead of windows. VR images were created according to the experimental variables, EEG measurements were taken, and data preprocessing and statistical analysis were performed. The study found that, first, small windows in a small room do not significantly affect EEG, while large windows influence multiple brain regions and frequencies, highlighting the importance of window size. To promote the user's physical and physiological well-being, windows larger than a certain size are necessary. Second, images placed instead of windows in a small room also had a significant effect on EEG, with their impact on brain waves similar to that of large windows. Even without the functional roles of the window such as natural lighting, ventilation, and evacuation, installing images resembling the external environment can have positive effect. Third, the EEG analysis results were consistent with the post-experiment questionnaire, though participants preferred actual windows over images. This study provides objective evidence on the physiological effects of windows in architectural spaces and inderscores the need for research that considers the complexity of real spaces.
