That is, the power consumption data of the first floor of the building measured on June 4 (Monday) stored in the data collection and storage device 7 and on May 27 (Monday), one week before, are used as statistical processing means 8. And the hourly power consumption is calculated using the date and time information, and the result is displayed as a line graph 110. Further, the analysis processing means 9 compares the time transition of the power consumption of last week and this week. In this week, since it is determined that the power consumption after 18:00 in the evening has increased, a determination comment 111 of “1F power increase at night” is notified.

  In addition, the example shown in FIG. 4 is a bar graph in which the horizontal axis 112 is displayed on each floor along with the power usage amount on Monday, June 4, the same as the above FIG. The total amount 113 of power consumption and the electricity bill 114 are clearly indicated by numerical values. Also in this example, the statistical processing means 8 calculates the power consumption of each floor for each usage type of air conditioning and lighting based on the usage type information and the section information, and the analysis processing means 9 calculates the power consumption of each floor last week and this week. Based on the result of analyzing the increase, a bar graph is displayed and a determination comment 115 of “6F increased air conditioning power consumption” is notified. In addition, it is desirable to display the bar graph and the line graph with an animation such as displaying them sequentially from the left to the right while facilitating the interest of people.

  FIG. 5 shows an example of an energy-saving bulletin board displayed on the hall display device 15. This energy-saving bulletin board is dated 116 and judgment comments 117 such as "1F power night increase from the previous week of 6/4 (Monday). Please cooperate with energy conservation." And "Air conditioning starts from the end of June." The information transmission message 118 is displayed as a list to encourage energy users in the building 1 to conduct energy-saving awareness and to transmit information related to energy consumption. The power consumption graphs (FIGS. 2 to 4) and the energy saving bulletin board (FIG. 5) may be displayed so that the screen is automatically switched at a predetermined time such as every 30 seconds. Only the power consumption graph may be automatically switched in a predetermined time while displaying the power consumption graph and the energy saving bulletin board side by side.

  As shown in FIG. 6, the floor display device 16 mainly displays unique information and environmental state mainly on each floor with numerical values and characters. In FIG. 6A, the electricity charge of yesterday on this floor is notified as “Yesterday electricity charge 120,000 yen / day”. Also, the discomfort index calculated from the current temperature / humidity and the temperature and humidity on the same floor are “room temperature 27.6 ° C.” (b), “room humidity 50.3%” (c), “comfort index comfort” (74) ”(d) is displayed, and in addition, an energy saving instruction comment such as“ lunch break energy saving monitor power off ”(e) or“ lunch energy saving lighting power off ”(f) is displayed in anticipation of the break time.
