So the Japanese government has directed large-scale electricity users to curb their consumption by 15 percent of what they used last summer.

As a result, it was found that the rise of temperature leads to the sharp decline of productivity and comfort, and that power saving of lighting made less dissatisfaction for office workers and reduced more electric energy than turning up the air conditioning. Office workers can keep productivity if there are no dissatisfactions for them. Therefore, lowering illuminance is found to be more effective for saving electricity than turning up the air conditioning.
