Effect of saving Measures on power Consumption reduction: Energy conservation based on field survey in summer power-saving office buildings after the Great East Japan Earthquake

The Great East Japan Earthquake on March 11, 2011 caused widespread damage, especially electricity shortage. Therefore the Japanese government has directed large-scale electricity users to curb their consumption by 15 percent of what they used in the previous summer. Most companies in Tokyo were saving electricity by reducing their use of lights and air conditioning systems in their offices. decline. Few field investigations have been conducted under special conditions including after big disasters. Purpose of this study is to find efficient strategies for saving electricity that do not decrease workers' productivity so much. In this report, energy consumption of existing building have analyzed and prepared between before the great east Japan earthquake and after. Further, it experimented on the conditions which changed an illumination setup and an air-conditioning setup under power-saving environment, and conducted the sensitivity analysis of each item in analyzing the power consumption on each condition.
