In indoor spaces, this study investigated that color temperature of lighting has an effect on environment of users and spaces, and then proposed suitable 'Correlated Color Temperature(CCT)' of lighting for application of space. For investigation about preference, work efficiency, visual fatigue, and so on for variation of CCT in the space, the clinic experiment was examined in office space which installed CCT-control-system. And with the questionnaire on the same condition, this study verified results of the clinic experiment with those of questionnaire. Furthermore, making the questionnaire about CCT of the offices as well as living-room and bed-room of the house, this study investigated suitable CCT for used purpose of various spaces. This study investigated the influence that the variation of CCT could have on environment of spaces, and presented appropriate CCT for application of space.
