ENERGY SAVING SUPPORT DEVICE, ENERGY SAVING SUPPORT METHOD AND ENERGY SAVING SUPPORT PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an energy saving support device for clearly classifying the respective areas of peak electric energy, base electric energy and regular electric energy on a load duration curve, and for accurately and easily discriminating an area where power consumption is excessive.SOLUTION: A load duration curve obtained by successively connecting the vertices of bar graphs created by rearranging the power consumption of an energy saving object in each unit time on a selected measurement date in the descending order is created by a load duration curve creation part 32, and the load duration curve is analyzed. Respective areas such as a peak electric energy area during the use of equipment consuming a power of a certain power threshold or more in use, a regular electric energy area during the use of equipment consuming a power of less than the power threshold in use, and a base electric energy area only for equipment consuming a power all the time are classified by an area discrimination part 33. Which area has excessive power consumption is determined on the basis of whether or not the rate of the area-categorized total power consumption of each area to the whole power consumption of the energy saving object exceeds the threshold of each area determined for each season by an excessive power consumption area discrimination part 34.
