Some field surveys were conducted in the offices in Tokyo to investigate worker's comfort and productivity under the saving electricity after the Great East Japan Earthquake. However, we need nationwide survey because saving electricity is ongoing all over Japan now. In this study, we conducted web-based questionnaire in Tokyo, Nagoya and Osaka to know the workers' awareness and measures of saving electricity. As a result, similar saving electricity measures were implemented in three areas and lowering illuminance made less dissatisfaction than turning up the set point of the air conditioning. It is estimated that workers' awareness of saving electricity was different because of the areal targeted value of saving electricity. Workers' satisfaction of the office environment was affected to a large degree by not only indoor environment or their gender and age, but also their feelings.
