A lighting control method has been proposed which adjusts the circadian rhythms of office workers and eliminates a decrease in the arousal level in the afternoon by exposing a high intensity of light in the morning in order to improve their productivity. As a result, it was found that the task performance of the CPTOP test under 2,100 lx was significantly(More)

The authors have developed a performance test, CPTOP2 (Cognitive Performance Test of Productivity), which consists of four task tests to evaluate cognitive abilities of office workers in order to quantitatively and objectively evaluate their productivity by controlling office environment. In addition, the testing time of CPTOP2 becomes shorter than(More)
