    Abstract

    Changes of the energy consumption in welfare facilities before and after the Great Earthquake of East Japan were analyzed based on the investigation for development of the DECC. Both electricity and primary energy consumption in the facilities with the residential function were reduced by approximately 8% in the Tohoku region and 16% in the Kanto region in 2011 compared to those in 2010 even though the difference of air temperatures were taken into consideration. As the results from multivariate analyses, measures related to lighting were effective for energy savings in the facilities both with and without the residential function. Additionally, changes of setting temperature of freezers could be a strong factor for energy savings in the facilities with the residential function, whereas restriction of use of electric appliances such as portable electric pots had large influences in the facilities without the function.
