JP 2009-98991 A

  Since the function as an energy management system according to the technology described in Patent Document 1 described above is to set a basic unit reduction rate for each business category, when applied to building management, a target value for each building Is not clearly set, and there is a problem that it is difficult to implement a reduction measure without knowing the specific target value of energy usage in each building. Specifically, when trying to determine the energy target for the next fiscal year for each building, the indicators are not clearly defined, and how much energy can be actually used for each building. Since it is difficult to determine the appropriate amount of energy reduction, it is difficult to handle practically and is inconvenient.

  The present invention has been made to solve such problems, and its technical problem is that the target value of energy consumption can be set fairly for each building, and the basic unit reduction rate of each business category can be reduced. The object is to provide an energy usage management system that can be easily achieved.

  In order to solve the above technical problem, the energy usage management system of the present invention has a plurality of business categories for each of the plurality of business classifications via a communication network by terminal means installed on a business facility side having a plurality of business classifications. An energy management system that collects and manages the energy usage measured by the energy usage measurement means installed in each building, and the terminal means holds multiple business classifications and basic unit indices for multiple buildings Business category management means to manage and unit consumption reduction rate management means to maintain and manage the basic unit reduction rate for multiple business classifications for each year, and multiple buildings belong to each of the multiple business classifications Building affiliation management means for holding and managing building affiliation information indicating whether or not, a basic unit index management means for holding and managing a basic unit index monthly, and energy of a plurality of buildings Energy usage management means that holds and manages monthly target values and actual values for each month, basic unit reduction rate from basic unit reduction rate management means, multiple business classification codes from business classification management means In addition, based on the building affiliation information from the building affiliation management means, the basic unit index for the plurality of buildings belonging to the plurality of business classifications in the basic unit index management means is calculated and set monthly, and the basic unit Based on the result of calculating the degree of achievement of the basic unit reduction rate within the multiple business categories from the reduction rate management means up to the previous month, the building occupies the multiple business categories for the multiple buildings Energy usage target calculation setting means for calculating and setting the current month of the target value of energy usage in the energy usage management means according to the original ratio of the unit index And butterflies.

  In the above energy usage management system, the energy usage target calculation setting means performs the calculation of the weighting of the ratio of the basic unit index when it can be confirmed that the basic unit reduction rate exists in the current year and cannot be confirmed. If there is a building code belonging to the business classification code for each applicable building code extracted from the building affiliation information, the weighting is not calculated. The total energy consumption from the start month to the previous month for the current fiscal year of each building and the previous year is converted into the total energy consumption from the start month to the previous month for the current fiscal year for each building and the previous year. At the same time, the total value of basic unit index data from the start month of the current year to the previous month is added to the start of the current year for each business category. From the start month to the previous month, and if not, calculate the amount of excess energy used for each business category from the start month to the previous month, and then It is preferable to calculate the weight.

  According to the energy usage management system of the present invention, the company's equipment side manages the monthly basic unit index and the actual value of energy usage for each building. Each building can calculate and set the target value of the energy consumption for the current month according to the ratio of the basic unit index in the business classification of the corresponding building based on the target achievement rate (target achievement) of the basic unit reduction rate. By transferring the target value of energy usage to the manager equipment side from the provider equipment side and displaying it on the display screen, it becomes easy to specifically implement measures for reducing energy usage for each building. As a result, energy usage based on the basic unit index of each building can be accurately managed (the target value of energy usage can be set fairly for each building, and the basic unit reduction rate of each business category can be easily achieved. Therefore, application in the building management field is effective.

  Hereinafter, an energy usage management system of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is an overall schematic block diagram showing a basic configuration of an energy usage management system according to Embodiment 1 of the present invention. In this energy usage management system, a data management device 2 as a terminal means installed on the side of a business facility having a plurality of business classifications is connected to a plurality of buildings for each business classification via a communication network 4 such as a network. It is configured as an energy management system that collects and manages the energy usage measured by the installed energy usage measuring means.

  If it demonstrates concretely with reference to FIG. 1, a company will correspond to OO product 1 and the business classification will be divided into two, the manufacturing sector 1A and the real estate sector 1B. The manufacturing sector 1A includes three buildings, a camera factory 1A1, an elevator factory 1A2, and an escalator factory 1A3. Each building here is equipped with dedicated energy usage measuring devices 1A1A, 1A2A, 1A3A. ing. In addition, the real estate business department 1B has three buildings, Tokyo branch 1B1, Omiya branch 1B2, and Kameari sales office 1B3. Has been. A data management device 2 and a display terminal device 3 are connected to each of these energy usage measuring devices 1A1A to 1A3A and 1B1A to 1B3A via a communication network 4. Each energy usage measuring device 1A1A to 1A3A, 1B1A to 1B3A has a communication function, and holds a total result of data obtained by measuring the energy usage in units of each building.

  The display terminal device 3 is separate from the data management device 2 and is installed on the manager's equipment side at a location remote from each building as in the case of the data management device 2. The data management device 2 is accessed to acquire various information from the database 2A, and the target value and actual value of the energy usage for each building calculated by the data management device 2 on the business facility side are displayed on the display screen 3A. A list can be displayed. Therefore, the data management device 2 has a function of providing information of the database 2A for access from the display terminal device 3. However, if the operator and the administrator are the same, a configuration including only the data management device 2 may be used.

  The data management device 2 stores, as the database 2A, a business classification management table 2A1 serving as a business classification management means that holds and manages each business classification (manufacturing sector 1A, real estate sector 1B) and a basic unit index for each building. And the basic unit reduction rate management table 2A2 as a basic unit reduction rate management means for maintaining and managing the basic unit reduction rate for each business classification for each fiscal year, and which business category each building belongs to A building affiliation table 2A3 serving as a building affiliation management means that retains and manages building affiliation information, and a basic unit index management table 2A4 serving as a basic unit index management means that retains and manages basic unit indices on a monthly basis; An energy usage management table 2A5 that is an energy usage management means for holding and managing monthly target values and actual values of energy usage of each building, Eteiru.

  Further, the data management device 2 uses the basic unit reduction rate from the basic unit reduction rate management table 2A2, the code of each business category from the business category management table 2A1, and the building affiliation information from the building affiliation table 2A3. The basic unit index for each building belonging to each business category in the unit index management table 2A4 is calculated and set monthly, and the basic unit reduction rate in each business category from the basic unit reduction rate management table 2A2 is set. Based on the result of calculating the degree of goal achievement up to the previous month, calculate the target value for the current value of energy usage in the energy usage management table 2A5 according to the ratio of basic unit index in each business category for each building Thus, it has a function as energy usage target calculation setting means. However, the basic unit reduction rate for each business category and the target value of energy usage of each building can be set from the next fiscal year after the system is in operation. Accordingly, regarding the setting of the target value, the basic unit reduction rate of the basic unit reduction rate management table 2A2 and the energy usage target value of the energy usage management table 2A5 are set from the next year of the system operation year.

  FIG. 2 is a diagram illustrating data in the business classification management table 2A1 of the database 2A provided in the data management apparatus 2. Referring to FIG. 2, in the business classification management table 2A1, the business classification is managed by the business classification code 2A1A and the business classification name 2A1B, and the basic unit index is the fine classification number 2A1C, the fine classification number branch number 2A1D, and the fine classification name. 2A1E, basic unit index name 2A1F, and basic unit index unit 2A1G. In addition, the business classification code 2A1A, the fine classification number 2A1C, and the fine classification number branch number 2A1D are set as main codes.

  FIG. 3 is a diagram exemplifying data in the basic unit reduction rate management table 2A2 of the database 2A provided in the data management apparatus 2. Referring to FIG. 3, the basic unit reduction rate management table 2A2 includes a business classification code 2A2A, a year 2A2B, and a basic unit reduction rate 2A2C. In addition, the business classification code 2A2A and the year 2A2B are set as main codes.

  FIG. 4 is a diagram illustrating data of the building affiliation table 2A3 of the database 2A provided in the data management device 2. Referring to FIG. 4, the building affiliation table 2A3 includes a building code 2A3A, a building name 2A3B, a business classification code 2A3C, and an IP address 2A3D. In addition, the business classification code 2A3C and the IP address 2A3D are set as main codes.

  FIG. 5 is a diagram exemplifying data in the basic unit index management table 2A4 of the database 2A provided in the data management apparatus 2. Referring to FIG. 5, the basic unit index management table 2A4 includes building code 2A4A, year 2A4B, April 2A4C, May 2A4D, June 2A4E, July 2A4F, August 2A4G, August 2A4H and September 2A4H. It consists of October 2A4I, November 2A4J, December 2A4K, January 2A4L of the following year, February 2A4M, and March 2A4N at the end of the year. In addition, the building code 2A4A and the year 2A4B are set as main codes. Incidentally, in this basic unit index management table 2A4, it is assumed that 2010 is an operation year, and no reduction target value for the operation year is set. The data of each month 2A4C to 2A4N is updated when the data base unit index of the corresponding building is determined by the data management device 2. The timing of such update is the time when the basic unit index is sales, when it is finalized on the last day of each month, or when the basic unit index is the total floor area, it is the fixed year-end value in April at the beginning of the year. In other words, in the basic unit index management table 2A4, the basic unit index data of each month 2A4C to 2A4N has two characteristics: a characteristic that is not determined until the last day of each month, and a characteristic that has a fixed value throughout the year. There are types.

  Depending on the basic unit index assigned to each building according to the characteristics of the basic unit index, there are cases where there is no data for the current month in the position index management table 2A4. The building codes T0001 to T0003 of the building affiliation table 2A3 are the business classification code J0001, and if the business classification management table 2A1 is collated, the basic unit index is sales, so the basic unit index management table 2A4 includes the current month. It shows that there is no data. On the other hand, the building codes T0004 to T0006 of the building affiliation table 2A3 are the business classification code J0002, and if the business classification management table 2A1 is checked, the basic unit index is the total floor area. Therefore, the basic unit index management table 2A4 includes It shows that there is data for the current month. In this way, the data in the basic unit index management table 2A4 is input from April 2011 to March 2012, depending on the basic unit index assigned to the building, for example, when the current time is June 2011 And those already input data from April to May 2011.

  FIG. 6 is a diagram illustrating data in the energy usage management table 2A5 of the database 2A provided in the data management device 2. Referring to FIG. 6, the energy usage management table 2A5 includes a year 2A5A, a month 2A5B, a building code 2A5C, an energy usage target value 2A5D, and an energy usage actual value 2A5E. In addition, year 2A5A, month 2A5B, and building code 2A5C are set as main codes.

  The data management device 2 refers to the database 2A, communicates with each energy usage measuring device 1A1A-1A3A, 1B1A-1B3A by the IP address 2A3D of the building affiliation table 2A3, and measures the energy usage of each building And the measured value data is reflected on the actual energy usage value 2A5E of the record having the same building code 2A5C data for the current month in the energy usage management table 2A5 of the database 2A. The business classification codes 2A1A, 2A2A, 2A3A for the three tables of the business classification management table 2A1, the basic unit reduction rate management table 2A2, and the building affiliation table 2A3 in the database 2A indicate the same data. However, the basic unit index of the business category to which the building belongs and the basic unit reduction rate for the current year are required. The data management device 2 calculates the energy usage target value for the current month of each building in the energy usage management table 2A5. This calculation processing is executed when the first day of each month is reached. To do.

  FIG. 7 is a flowchart showing the calculation processing of the energy usage target value for the current month of each building by the data management device 2. In such a calculation process, first, by referring to the basic unit reduction rate management table 2A2 of the database 2A and searching the basic unit reduction rate data for the current year, the record search for the current year in the basic unit reduction rate management table 2A2 (step After performing the process of S101), it is determined whether there is a record for the current year (step S102). As a result of this determination, if there is no basic unit reduction rate data for the current year, the operation process is terminated. However, if there is basic unit reduction rate data for the current year, the business classification code 2A2A and the basic unit reduction rate 2A2C are extracted ( Step S103), and processing is performed for each business category.

  Next, with reference to the building affiliation table 2A3, by checking the data of the building code 2A3A of the building having the data of the business classification code 2A2A extracted earlier for each record, it is determined whether or not the building code 2A3A exists ( Step S104) is performed. If there is no building code 2A3A as a result of this determination, the process returns to the process before the determination of whether or not there is a record for the current year (step S102) and the subsequent processes are repeated. It is determined whether or not each month from the first month (April) to the current month (step S105). As a result of this determination, if processing is not performed from the first month of the year to the current month, the basic unit index management table 2A4 is referred to, and the basic unit index data of the corresponding month of the corresponding building code 2A4A is searched. Then, it is determined whether or not there is a basic unit index data for the corresponding month of the current year (step S106). If there is no basic unit index data, as a substitute for the basic unit index by building for the corresponding month of the current year, After performing the process of retrieving the basic unit index data of the previous month (step S107) by searching the basic unit index data of the current month and extracting the records, Another month from the beginning of the fiscal year to the current month after the process of adding the basic unit index data of the extracted record to the total unit value of April to the current month (step S108) It was determined whether or not to repeat the return to subsequent processing prior to (step S105).

  On the other hand, if it is determined from the first month of the previous fiscal year to the current month that it is processed from the first month of the fiscal year to the current month (step S105), the basic unit index table 2A4 and energy usage management With reference to the table 2A5, calculation of the basic unit for the month from April of the previous fiscal year to the previous fiscal year is performed (step S109). The basic unit for the previous April to the previous fiscal year for each building is the total energy consumption value from April to the previous fiscal year for each building, and the basic unit index value from April to the previous fiscal year for the previous fiscal year. It is obtained by dividing by the total value of.

  Subsequently, by referring to the energy usage management table 2A5, calculation of the total energy usage actual value from April of the current fiscal year to the current fiscal year is performed (step S110). The total energy consumption actual value from April of this fiscal year to the current month of last year is obtained by summing the actual energy consumption values of each building from April of the current fiscal year to last month of the current fiscal year. As a result of the above, the basic unit reduction rate, the total value of basic unit index for the current fiscal year from April to the current fiscal year, the previous fiscal year for the previous fiscal year by building, and the basic unit for the current fiscal year for the previous fiscal year The value is obtained.

  Further, calculation of the temporary energy usage target value for each building before weighting the achievement rate of the basic unit reduction rate for each business category (step S111). The provisional target for energy use by building is {(April from the previous fiscal year by building to the previous year's basic unit) x (100-Basic unit reduction rate)} / 100 x {(April from the current fiscal year by building to the current month's original) Unit index total value)-(April year-to-date last month energy usage total value by building)}. Thereafter, in order to weight the achievement rate of the basic unit reduction rate for each business category fairly, a process of calculating the weighting of the ratio of the basic unit index of each building (step S112) is performed, and the temporary energy usage amount by building is calculated. The weighting is added to the target value, and the building-specific energy usage target value is calculated (step S113). That is, the true energy usage amount target value for each building here is obtained by adding a weight to the temporary energy usage target value for each building.

  Subsequently, the energy usage amount management table is stored by storing the obtained energy usage target value for each building as data of the energy usage target value for the record of the current building code 2A5A in the energy usage management table 2A5. After performing the process of storing data in 2A5 (step S114), the process returns to before determining whether there is a building code 2A3A (step S104) and the subsequent processes are repeated.

  FIG. 8 is a flowchart showing details of the process of calculating the weighting of the ratio of the basic unit index included in the calculation process shown in FIG. 7 (step S112). In the details of the process of calculating the weighting of the ratio occupied by the basic unit index (step S112), first, the building affiliation table 2A3 is referred to, and the business classification code 2A3C of the corresponding building code 2A3A is extracted from the building affiliation table 2A3 (step S201). ), The building code 2A3A of the corresponding business classification code 2A3C is extracted from the building affiliation table 2A3 (step S202).

  Next, in order to perform processing for each extracted building code 2A3A, it is determined whether or not there is a building code 2A3A of the extracted business classification code 2A3C (step S203). As a result of this determination, if there is a building code 2A3A, the energy usage management table 2A5A is referred to, and the building code 2A3A is extracted from the actual values of energy usage from April to last month of the current year. After calculating the total energy consumption from April to last month by building (step S204), the total energy consumption from April to last month by building is calculated from April to last month by business category. Add to the total value (step S205). Furthermore, by referring to the energy usage management table 2A5A and summing up the building code 2A3A, which is obtained by extracting the actual values of energy usage from April of the previous year to the previous month of the previous year, After calculating the total amount of energy consumption from month to previous year (step S206), the total amount of energy consumption from April to previous year by building was calculated from April to the previous year by business category. Add to the total value (step S207). Subsequently, after referring to the basic unit index management table 2A4A and summing the data of the basic unit index from April of this year to the previous month (step S208), the obtained total value is calculated from the April of this fiscal year to the previous month of the current fiscal year. After adding to the unit index total value (step S208), the basic unit index management table 2A4A is referred to and it is determined whether or not the building code 2A3A corresponds to the weighting target (step S209). As a result of this determination, if it matches with the corresponding building code 2A3A to be weighted, the calculated total value is assigned to the total unit index value for the current month from April of the current fiscal year to the current year (step S210). In the same manner as in the case where it does not match the corresponding building code 2A3A to be subjected to the determination, it is determined whether or not there is a building code 2A3A extracted in order to perform the processing for each previously extracted building code 2A3A (step Return to S203) and repeat the subsequent processing.

  On the other hand, as a result of determining whether or not there is the extracted building code 2A3A (step S203), if there is no building code 2A3A, the achievement rate of the basic unit reduction rate is obtained from the energy usage for each business category. Calculation of excess energy consumption by business category from April to last month (step S211) after calculating the amount of excess energy used by business category, and then calculating the weighting ratio of the basic unit index After performing (Step S212), the operation process is terminated. Incidentally, the amount of surplus energy used by business category is {(total amount of energy usage from the previous year April to the previous year by business category) x (100-basic unit reduction rate) / 100}-(current year by business category) (April to last year's last month's total energy consumption). In addition, the weighting of the ratio of the basic unit index is the amount of surplus energy used by business category × (April year-to-date last month base unit index total by building) ÷ (April year-to-business year base unit per month Index total value). That is, in the calculation of the building-specific energy usage target value (step S113) in FIG. 7, the basic unit index is added to the building-specific energy usage temporary target value calculated in step S111. A value obtained by adding the weighting values obtained in the calculation of the weighting of the proportion occupied by (step S212) is calculated. However, on April 1 at the beginning of the year, the total amount of energy used and used by business category up to April 1 of the current year is “0”, and the amount of surplus energy used by business category is “0”. The weighting value obtained by calculating the weighting of the ratio of the basic unit index (step S212) is 0, and the true target value of the energy usage of each building in April at the beginning of the year is equal to the temporary target value. .

  In the function of setting the energy usage target calculation of the data management device 2 described above, the calculation of the weighting of the ratio occupied by the basic unit index is performed when it can be confirmed that the basic unit reduction rate exists in the current year, and cannot be confirmed. In the case of weighting calculation, it is determined whether there is a building code belonging to the business classification code 2A3C for each corresponding building code 2A3A extracted from the building affiliation information in the building affiliation table 2A3, If present, the total amount of energy used from the current fiscal year for each building, and from the starting month to the previous month for the previous fiscal year, is used as the energy usage from the starting month for the current fiscal year for each building and the previous fiscal year to the previous month. In addition to the total amount, the total value of the basic unit index data from the start month of the current fiscal year to the previous month is assigned to each business category. Of the basic unit index from the start month to the previous month, and if it does not exist, calculate the amount of surplus energy used for each business category from the start month to the previous month, and then If the basic unit reduction rate is determined for each business classification to calculate the weight, the target value of each month's energy usage of each building is calculated and set easily with a fair index, and the display terminal device 3 display screen 3A.

  The display terminal device 3 obtains various information in the database 2 by accessing the data management device 2 through the network 4, and uses the energy data of the current year, current month, and current day based on the time data of its own device. The data related to the target value and other acquired data can be displayed on the display screen 3A. If the display pattern on the display screen 3A shown in FIG. 1 is specifically described, for example, the business category name 2A1B and the business category code 2A1A are acquired from the record of the business category management table 2A1, and on the display screen 3A. Data of the business classification name 2A1B can be displayed in the business separation name area 3A1. Further, a record having the same data as the data of the business classification code 2A1A is searched from the record of the basic unit reduction rate management table 2A2, and the basic unit reduction rate on the display screen 3A is obtained from the data of the basic unit reduction rate 2A2C obtained from the corresponding record. It can be displayed in the basic unit reduction rate display area 3A2 indicating the rate target. Further, from the building affiliation table 2A3, a record having the same data as the data of the business classification code 2A1A is searched, and the data of the building name 2A3B and the data of the building code 2A3A of the corresponding record are obtained for each corresponding record. From the energy usage management table 2A5, a record having the data of the same building code 2A3A and the data of the current month is retrieved, and the data of the energy usage target value 2A5D and the data of the actual energy usage amount 2A5AE are acquired. In the energy usage target display area 3A3 indicating the energy usage for January on the display screen 3A, the building name display area 3A3A contains data of the building name 2A3B, and the target value display area 3A3B contains the energy usage target value 2A5D. Data, actual value display area 3A3C It can display data of the energy consumption actual value 2A5AE respectively.

  In short, according to the energy usage management system according to the first embodiment, the data management device 2 on the business facility side manages the monthly basic unit index and the actual value of energy usage for each building, On the other hand, the target of energy consumption for the current month is based on the ratio of the basic unit index to the business classification to which the building belongs based on the target achievement rate (target achievement) of the basic unit reduction rate in the business classification up to the previous month. Since the value can be calculated and set, the target value of energy usage for each building is transferred from the business equipment side of the data management device 2 to the management equipment side of the display terminal device 3 and displayed on the display screen 3A. As a result, it becomes easier to specifically implement measures for reducing energy consumption for each building. As a result, the target value of energy consumption can be set fairly for each building, and the unit reduction rate for each business category can be easily achieved. Can be managed.
