Abstract

The illuminance and color temperature of a light source affect the perceived atmosphere of interior lighting. However, few studies have investigated the environmental lighting preferences of people in developing countries, such as those in Southeast Asia. In particular, the evaluation characteristics of people who live in such areas have not been clarified. Therefore, we conducted an experiment on interior lighting to determine the difference in the evaluation characteristics of illuminance and color temperature between Japanese and Thai people. As a result, we found a significant difference in their preferred brightness for interior lighting- Thai people evaluated low illuminance interior lighting as being brighter than Japanese people.
