In this study, the authors conducted the experiment in the virtual environment to verify the physiological restorative effect of the Green Design Office. As a result, when the conventional design office has changed into the Green Design Office, the averages of standardized SCL values significantly increased (p<.01). Moreover, it was suggested that the increase of the restorative effect of arousal level was more obvious when the workers were aware of the Green Design Office. Those results indicate that it is important to set the green elements and make the office workers aware of it in the office.
