  The periodic report and the non-periodic report are reports of energy saving activities for the purpose of energy saving in the stores 1a, 1b,. The regular report is periodically created by the regular report unit 22b, and the non-periodic report is temporarily created when there is a problem with the non-periodic report 22c. Further, the regular report and the non-periodic report are created by further analyzing the result of the basic analysis by the basic analysis unit 22a.

(6-1) Basic Analysis The basic analysis unit 22a performs basic analysis (FIG. 5) as preprocessing for creating a regular report and a non-periodic report at intervals of time T2 (in this embodiment, one day). Step S1) is executed. That is, the process of FIG. 5 is executed every time the time T2 elapses.

  In the basic analysis, the violation amount for each control point at the immediately preceding time T2 is calculated. The violation amount is an added value of the increased energy amount and the energy saving amount. That is, the violation amount is an index that quantitatively represents the violation operation that violates the energy saving operation rules. The management point can be a store unit, a department unit, or an indoor unit unit, but in the following description, it is assumed that the store unit is selected in advance by the staff of the headquarters 3. Therefore, more specifically, the basic analysis unit 22a refers to the indoor unit database 25a and the violation amount database 25b, and for each store 1a, 1b,. An added value of the energy increase amount and the energy saving amount at the immediately preceding time T2 is calculated.

The compliance rate is a ratio of management points at which the violation amount does not exceed a predetermined threshold. In other words, the compliance rate is an index representing the degree to which the energy saving operation rules are observed in the entire management point. More specifically, the basic analysis unit 22a counts the number of stores (the number of violating stores) whose violation amount at the immediately preceding time T2 is equal to or less than a threshold (for example, 0 or less, that is, on the energy saving side) The ratio of the number of violating stores to the number is calculated. Therefore, for example, when there are 1000 stores 1a, 1b,..., And the amount of violation at the immediately preceding time T2 is less than or equal to the threshold at 100 stores, the compliance rate at the immediately preceding time T2 is 10 %.

  The compliance rate is stored in the storage unit 25 in association with the corresponding time slot (the time width is T2 = 1 day, for example, defined as “○ year × month Δ day”). .

(6-2) 1st detailed analysis The regular report part 22b performs the 1st detailed analysis which produces a regular report at the interval of time T3 (this embodiment 1 month). The first detailed analysis is performed less frequently than the basic analysis. Moreover, the regular report part 22b will transmit the email which attached the said regular report to the staff of the headquarters 3, when preparation of a regular report is complete | finished. It is assumed that the e-mail address addressed to the staff at the headquarter 3 is registered in the storage unit 25 in advance. In the first detailed analysis, the following contents to be included in the periodic report are calculated.

6-2a) Total violation amount In the first detailed analysis, the violation amount for each management point at the immediately preceding time T3 is calculated by using the result of the basic analysis.

  Subsequently, in the first detailed analysis, the total amount of violations (referred to as the total violation amount) of all the management points at the immediately preceding time T3 is calculated. In other words, the regular reporting unit 22b accumulates the violation amount at the previous time T3 that has been calculated for each management point, and sets the total violation amount.

  In addition to being output on the periodic report, the total violation amount is associated with the corresponding time slot (the time width is T3 = 1 month, for example, defined as “○ year × month”). Are stored in the storage unit 25.

  Further, the periodic report unit 22b also outputs a history graph of the total violation amount calculated every time T3 on the periodic report. More specifically, the regular reporting unit 22b reads data of six total violation amounts for the past six months from the storage unit 25, and plots the data on a space where the vertical axis represents the total violation amount and the horizontal axis represents time. Therefore, the headquarters 3 staff who saw the periodic report can easily grasp the time transition of the total violation amount.

6-2b) Compliance Rate In the first detailed analysis, a compliance rate at the immediately preceding time T3 is calculated. More specifically, the regular reporting unit 22b counts the number of stores (the number of violating stores) whose violation amount at the immediately preceding time T3 is equal to or less than a threshold (for example, 0 or less, that is, on the energy saving side) The ratio of the number of violating stores to the number is calculated. Therefore, for example, when there are 1000 stores 1a, 1b,..., And the amount of violation at the immediately preceding time T3 is less than or equal to the threshold at 100 stores, the compliance rate at the immediately preceding time T3 is 10 %.

  In addition to being output on the periodic report, the compliance rate is related to the corresponding time slot (the time width is T3 = 1 month, for example, defined as “○ year × month”), Accumulated in the storage unit 25.

  The regular report unit 22b also outputs a history graph of the compliance rate calculated every time T3 on the regular report. More specifically, the periodic report unit 22b reads data of six compliance rates for the past six months from the storage unit 25, and plots the data on a space where the vertical axis is the compliance rate and the horizontal axis is time. Therefore, the headquarters 3 staff who saw the periodic report can easily grasp the time transition of the compliance rate.

6-2c) Average Value, Median Value, and Mode Value The regular report unit 22b calculates the average value, median value, and mode value of the data group of the violation amount at the time T3 immediately before each control point. The median is the value of the violation amount in the middle of the number of data (that is, the number of management points) on the frequency distribution of the data group, and the mode value is the number of data on the frequency distribution of the data group ( That is, it is the value of the violation amount where the management point) is the maximum.

  The average value, median value, and mode value are output on the periodic report and the corresponding time slot (the time width is T3 = 1 month. For example, “○ year × month” is defined. Are stored in the storage unit 25.

To do. Therefore, the staff of Headquarters 3 who has seen the periodic report can easily grasp the time transition of the variation of the violation amount between the management points.

6-2e) Distribution Graph The regular reporting unit 22b creates a distribution graph of management points for each violation amount at the immediately preceding time T3 as shown in FIG. 6 and outputs it on the regular report.

  More specifically, the periodic reporting unit 22b divides the violation amount axis by a predetermined width, and counts the number of violation amount data at the immediately preceding time T3 that falls within each width, thereby determining the number of violations by store. Create a frequency distribution. Then, the frequency distribution is graphed in a two-dimensional plane with the horizontal axis as the violation amount and the vertical axis as the number of stores.

  In addition to the distribution graph corresponding to the immediately preceding time T3 (see the distribution graph for “this month” in FIG. 6), the regular reporting unit 22b also distributes the distribution graph corresponding to the immediately preceding time T3 (see FIG. 6). Similarly, a distribution graph corresponding to the time T3 immediately before the relevant period (see the distribution graph of “last month” in FIG. 6) is created in the same manner. Then, the three distribution graphs in the three periods are arranged so as to overlap in the same two-dimensional plane. Therefore, the staff of the headquarters 3 can easily grasp the time transition of the distribution graph. Further, the average value and the median value of the violation amounts at the immediately preceding time T3 are also clearly shown in the same two-dimensional plane (see FIG. 6).

  In FIG. 6, the absolute number of stores that are management points is taken on the vertical axis, but other values that reflect the number of management points, such as the percentage of management points, can also be taken.

6-2f) Evaluation Comment on Mountain Characteristics The periodic report unit 22b derives mountains that appear on the three distribution graphs. In the present specification, “mountain” includes the meanings of both the entire distribution graph and the bumps of the distribution graph. Hump means the area around the maximum point of the distribution graph. For example, the surrounding area is the minimum point immediately to the left of the maximum point and the minimum point to the right (minimum point to the left or right). If there is no, it can be defined as the area between the left and right edges of the distribution graph. In the example of the distribution graph shown in FIG. 6, there is one hump on the increased energy side (area where the violation amount is 0 or more) and one on the energy saving side (area where the violation amount is 0 or less).

  The periodic report unit 22b derives an evaluation comment on the degree of penetration of the energy saving operation rules for the entire management point based on the derived mountain characteristics and outputs the comment on the periodic report. The characteristics of the mountain include, for example, the number of mountains, the position of the mountain, the interval between mountains when there are multiple mountains, the height of the mountain, and the width of the mountain. The evaluation comment is derived with reference to tabular data as shown in FIG. 7 stored in the storage unit 25. In the table of FIG. 7, there are four columns of “item”, “evaluation criteria”, “evaluation”, and “remarks”, but it is determined that the items in the “item” column meet the conditions described in the “evaluation criteria” column. In this case, the descriptions in the “evaluation” column and the “remarks column” are derived as evaluation comments.

  As shown in FIG. 7, when there are a plurality of humps, “There is a problem” “There is a problem at a specific control point (the operation schedule does not match the control point or the operation schedule is not observed)” Is included in the evaluation comment. Normally, when the driving schedule matches the control point, the distribution graph is predicted to have a bell mouth shape like a normal distribution. On the other hand, when there are multiple humps, This is because the schedule itself may not be appropriate. When the position of the hump exists on the energy increase side (the area where the violation amount is 0 or more), “There is a problem” and “The driving schedule does not penetrate” are included in the evaluation comment. If the interval between the bumps is wide, “There is a problem” and “There is a problem at a specific control point (the operation schedule does not match the control point or the operation schedule is not observed)” are included in the evaluation comment. .

  On the other hand, when the height of the entire distribution graph is low, or when the width of the entire distribution graph is wide, “there is a problem” and “the driving schedule is not thoroughly implemented” are included in the evaluation comment. Whether the width of the entire distribution graph is wide or narrow can be measured by the variance of the distribution graph or the standard deviation.

6-2g) Other Evaluation Comments The table in FIG. 7 holds evaluation comments corresponding to specific aspects of other items in addition to evaluation comments corresponding to specific aspects of mountain characteristics, and the conditions are satisfied. If it is determined that the evaluation is to be performed, the following evaluation comment is derived by the periodic report unit 22b and output on the periodic report.

  As shown in FIG. 7, the number of monitoring targets (the number of all management points to be monitored regardless of whether or not the data on the amount of energy increase and the amount of energy saved is collected) and the number of objects to be evaluated (the amount of energy increase and the amount of energy saving) If there is a deviation from the number of management points from which data is collected), “there is a problem” and “there are management points that are escaping the driving schedule” are included in the evaluation comment.

  Also, if the compliance rate is below the threshold, the average value is on the energy-saving side, the average value is above the threshold with the energy-saving side negative, the median is on the energy-saving side, the median is energy-saving If the value is above the threshold with the side negative, or if the variance or standard deviation is greater than the threshold, “problem” and “driving schedule not permeated” are included in the evaluation comment. When the difference between the average value and the median value is larger than the threshold value, “problem” and “the driving schedule is not kept” are included in the evaluation comment. If the median value is on the increased energy side rather than the average value, “problem” and “the driving schedule has not penetrated” are included in the evaluation comment.

  In addition, the current and previous results are also compared. More specifically, as shown in FIG. 7, when the height of the mountain (distribution graph as a whole or the hump) on the increased energy side is increasing, “problem” and “driving schedule cannot be observed” Is included in the evaluation comment. When the height of the mountain on the energy saving side (the entire distribution graph or hump) is decreasing, “no problem” and “no problem if the operating schedule penetration has increased” are included in the evaluation comment. It is done. If the compliance rate is decreasing, the average value is shifting in the direction of increasing energy, the median is shifting in the direction of increasing energy, or if the variance or standard deviation is increasing, "Problem" and "Driving schedule is not being followed" are included in the evaluation comment. Therefore, the staff of the headquarters 3 can easily grasp the time transition of the degree of penetration of the energy saving operation rules with respect to the entire management point.

(6-3) Second Detailed Analysis As shown in FIG. 5, the second detailed analysis (step S5) is executed in the following case.

  The non-periodic report unit 22c determines whether or not to execute the second detailed analysis for creating the non-periodic report every time the basic analysis of the interval of time T2 (step S1) ends (steps S2 and S3). .

  More specifically, the non-periodic report unit 22c is a predetermined time (this implementation) after the periodic report is issued last time or the notification (step S4) that the non-periodic report is issued is issued last time. In the embodiment, it is determined whether or not one week has passed (step S2), and if not, the process is terminated. On the other hand, if it has elapsed, it is further determined whether or not the result of the basic analysis satisfies a predetermined condition (step S3), and if satisfied, the second detailed analysis (step S5) is executed. On the other hand, when not satisfy | filling, it determines that 2nd detailed analysis (step S5) is not performed, and complete | finishes a process. As for the predetermined condition, for example, the compliance rate at the immediately preceding time T2 may exceed the threshold value once, exceed a predetermined number of times, or exceed a predetermined number of times within a predetermined period. . Alternatively, the compliance rate at the immediately preceding time T2 may be increased or decreased by a predetermined amount compared to the previous day or compared to the same period of last year. Alternatively, the cumulative value or the average value of the violation amounts of all the management points at the immediately preceding time T2 may exceed the predetermined threshold value. In addition, the cumulative value or average value of the violation amounts at all the management points at the immediately preceding time T2 is calculated by accumulating or averaging the violation amounts at the immediately preceding time T2 that have been calculated for each management point during the basic analysis (step S2). Is done.

  Further, when executing the second detailed analysis (step S5), the non-periodic reporting unit 22c simultaneously transmits a predetermined electronic mail to the staff of the headquarter 3 (step S4). It is assumed that the e-mail address addressed to the staff of the headquarter 3 is registered in the storage unit 25 in advance. The e-mail notifies the staff at Headquarters 3 that a non-periodic report will be issued, and at the same time the basic analysis results satisfy the specified condition, that is, how to comply with the energy-saving operation rules, or energy-saving operation Notifies that there is a problem with the rules themselves. An address (URL) in the storage unit 25 in which the non-periodic report created at the end of step S5 is to be saved is automatically inserted into the e-mail. The non-periodic report unit 22c transmits the non-periodic report to the Web browser of the terminal (usually the management terminal 30) that accesses the URL. That is, the staff of the headquarters 3 can easily browse the non-periodic report by accessing the URL described in the received e-mail.

  In the second detailed analysis (step S5), the content to be published in the non-periodic report is calculated. The contents published in the non-periodic report are values obtained by processing the amount of violations other than the previous time T3 from the contents published in the periodic report (total violation amount, compliance rate, average value, median value, maximum value) Frequency value, variance, standard deviation, distribution graph and evaluation comments) are omitted.

  Therefore, among the contents calculated in the first detailed analysis, the contents calculated in the second detailed analysis also include the violation amount for each management point at the immediately preceding time T3, the total violation amount and the compliance at the immediately preceding time T3. Rate, average value, median, mode, variance and standard deviation of violation amount at the previous time T3, distribution graph of control points by violation amount at the previous time T3 (see FIG. 8), and FIG. Only the evaluation comments corresponding to items other than “Comparison between previous and current” are included.

  In other words, in non-periodic reports, the analysis results excluding bibliographic items include the total violation amount and compliance rate at the previous time T3, the average value of the violation amount, the median, the mode, the variance and standard deviation, the violation The distribution graph of control points by quantity (see FIG. 8) and only evaluation comments corresponding to items other than the item “comparison between previous and current” in FIG. 7 are posted. Unlike the case of the periodic report, graphs of the total violation amount and the compliance rate at the immediately preceding time T3, and the average value, median value, mode value, variance, and standard deviation of the violation amount over time are not posted.
