This study examined a method for evaluating the brightness of a space using a reference space as a standard for judging brightness. Subjects observed the test and reference spaces, and made brightness match by adjusting illuminance of the reference space. Matching was carried out for a model box with three different conditions (Exp.1) and a full-sized room (Exp.2) under a wide range of illuminance. Brightness matches made for each of the test spaces were consistent within one subject and among all subjects. The relationship between illuminance of the reference space and that of the test space at equivalent brightness was found to be linear on a logarithmic scale. These results suggest that the reference matching method is useful for evaluating the brightness of a space. Some problems with this method are also discussed.
