Abstract


In order to verify the effect of a new light control which is expected to adjusts workers\¡Ç circadian rhythm on office productivity objectively and quantitatively, a large scale experiment has been conducted, where three task tests of CPTOP and their relevant simulation office tasks were given to 15 subjects who have experience working as an actual office worker. As a result, while the improvement of productivity for the proposed light control method against the conventional one was 1.87% to 5.49% depending on office tasks, little shown was improvement on CPTOP.
