At the same time, the government has been requiring power saving activities for the public after the Great East Japan Earthquake in 2011. This paper describes the present state of temperature, relative humidity, and CO2 concentration by using result of continuous measurement at four office rooms located in hot humid region in Japan. Additionally, result of questionnaire survey about power saving action in each target office room is shown. At one office room, at which the air conditioning’s setting temperature was as same as the upper limit of the reference of the Act, mean value of temperature was higher than the reference value in cooling period. In heating period, the mean value of the measurement result of relative humidity was approximately 30%RH, which is lower than the lower limit of the reference value of the Act. CO2 concentration was influenced by the power saving action. The measurement value of the concentration was proportionate to the strength of the power saving activities. Moreover, the measurement values are compared with Japan wide data obtained before the earthquake. The result of the comparison derives that the measured indoor environment are poorer quality. The quality seems that it was caused by the energy saving actions by analysing questionnaire survey results.}, publisher = {Society for Social Management Systems}, title = {INVESTIGATION ON INDOOR ENVIRONMENT AT OFFICES LOCATED IN HOT HUMID REGION IN JAPAN UNDER THE CONDITION OF POWER SAVING}, volume = {9}, year = {2014} }
