In S1, the specific equipment room power consumption basic unit calculation unit 151 of the power consumption analysis apparatus 10 receives the building power consumption data d1 and the DECC office building power consumption basic data d2 and inputs the specific equipment room power consumption basic unit. Data d11 is output. Specifically, the specific equipment room power consumption basic unit calculation unit 151 calculates the sample building i in n month from the power consumption F (i, n) [kWh / month] of the sample building i by month (for 12 months). Specific facility room power consumption F _m (i, n) [kWh / month] is extracted and divided by the area of the specified facility room, so that the specific facility room power consumption basic unit E _m (i, n) [KWh / m ² / month] is calculated.

In the present embodiment, it is assumed that the energy consumption characteristics in the floor other than the specific equipment room of the building are equivalent to those of a general office building. For this reason, the specific equipment room power consumption basic unit calculation unit 151 uses the floor area other than the specific equipment room of the sample building i from the power consumption F (i, n) [kWh / month] of the sample building i and the general The power consumption F _m (i, n) [kWh / month] of only the specific equipment room is calculated by subtracting the power consumption of the office building given by the product of the power consumption per floor area of the office.

Specifically, the specific equipment room power consumption basic unit separation unit 152 separates the specific equipment room power consumption basic unit into a specific equipment room base power consumption basic unit and a specific equipment room seasonally variable power consumption basic unit.

FIG. 4 is a diagram for explaining the specific facility room power consumption basic unit separation process. As shown in FIG. 4, the specific facility room power consumption basic unit separation unit 152 performs the specified facility room power consumption basic unit E _m (i, n) [kWh / m ² / Month], the month in which the power consumption basic unit is the minimum in n months (January to December) is N, and the specific equipment room base power consumption basic unit of sample building i is E _{m, B} ( i) (= E _m (i, N)) [kWh / m ² / month] In addition, the specific facility room power consumption basic unit separation unit 152 calculates the above-mentioned E _{m, B} (i) [kWh / m] from the specific facility room power consumption basic unit E _m (i, n) [kWh / m ² / month]. the value obtained by subtracting ² / month], specific equipment rooms seasonality power intensity _E m, and F (i, n) [kWh / m 2 / month. Therefore, the specific equipment room power consumption basic unit separation unit 152 performs the specific equipment room base power consumption basic unit E _{m, B} (i) [kWh / m ² / month] of the sample building i and the specific equipment room seasonal power consumption. intensity _E m, and F (i, n) [kWh / m 2 / month], can each be calculated by the following equation (2) and (3).

  In S3, the specific facility power consumption basic unit calculation unit 153 of the power consumption analysis device 10 performs the specific facility room power consumption basic unit base data d12 obtained by the separation in S2, the air conditioner performance data d3, the region The monthly average temperature data d4 is input, and the specific facility power consumption basic unit data d14 is output.

Specifically, the specific equipment room base power consumption basic unit E _{m, B} (i) [kWh / m ² / month] of the sample building i is the power consumption by the specific equipment as shown in the following equation (4). The unit E _{mech, B} (i) [kWh / m ² / month] can be _{divided into the} base power consumption basic unit E _{air, B} (i) [kWh / m ² / month] by the air conditioning equipment.

In the present embodiment, as shown in the following equation (5), the equipment configuration in the specific equipment room of the sample building i and the equipment load in the specific equipment do not change throughout the year, that is, the power from the specific equipment in the specific equipment room. It is assumed that the consumption unit E _{mech, B} (i) [kWh / m ² / month] does not change throughout the year.

FIG. 5 is a diagram for explaining the specific facility power consumption basic unit calculation processing. As shown in FIG. 5, the power consumption by the air conditioning equipment in the specific equipment room used when calculating E _{air, B} (i) of the above formula (4) is the month of the system COP (Coefficient Of Performance) of the air conditioning equipment. It can be estimated using the average value COP (i, n) and the air conditioning load of the specific equipment room determined by the influence of heat generated by the specific equipment and heat transfer between the outside air. That is, the specific equipment power consumption basic unit calculation unit 153 calculates the power consumption by the air conditioning equipment by dividing the sum of the heat generated by the specific equipment and the amount of heat transfer with the outside air by the value of the system COP.

Hereinafter, an assumption method of the system COP and the air conditioning load of the sample building i will be described, and a method of calculating the power consumption _basic unit E _{mech, B} (i) by the specific facility using the result will be described. The specific facility power consumption basic unit calculation unit 153 estimates the monthly average value COP (i, n) of the air conditioning system of the sample building i using the average temperature in N month when the base power was observed in S2.

  Note that the system COP of the air conditioning facility represents a ratio between the amount of heat processed in the target period and the amount of power consumed for processing the amount of heat. The COP calculated by adding the power consumed by the indoor unit to the power consumed by the outdoor unit is the system COP. The outdoor unit COP varies depending on the outside air temperature. In the cooling operation, the outdoor unit COP decreases as the outside air temperature increases. That is, the outdoor unit COP is lower in the summer and higher in the winter. On the other hand, when viewed from the system COP, the operating status of the indoor unit does not change greatly depending on the load processed by the air conditioning system. Therefore, the ratio of the power consumption of the indoor unit to the power consumption of the entire air conditioning system is about the winter. growing.

In the present embodiment, the system COP of the sample building i is assumed based on the relationship between the outside air temperature described in the catalog data of the air conditioner installed in the building and the system COP. Here, the monthly average value of the system COP when the device is operating under the same conditions as the catalog data is defined as COP _R (i, n). The catalog data used for the analysis is processed by the outdoor unit under a condition called a rated condition (for example, a load factor of 99%) with respect to the load factor represented by the ratio between the load processed by the air conditioning system and the processing capacity of the air conditioning system. The amount of heat is changed to the corresponding load factor. On the other hand, the operating conditions of each sample building i in which an air conditioner is actually introduced are worse than the rated conditions, and the system COP is lower than the catalog data.

  Therefore, the specific facility power consumption basic unit calculation unit 153 sets the conversion coefficient α (i) [−] for each sample building i, and calculates the monthly average value COP (i, n) of the system COP of the sample building i. It calculates based on following Formula (6). In the following equation (6), α is a value expressing a decrease from the catalog value of the system COP due to deterioration due to secular change or device arrangement in the specific facility room.

  Next, in the specific equipment power consumption basic unit calculation unit 153, the base power was observed in the specific equipment room using the internal heat generation amount of the specific equipment room and the heat transfer amount between the specific equipment room and the outside air. Estimate air conditioning load for N months. Here, throughout the year, the power consumption by the specific equipment in the specific equipment room matches the internal heat generation amount, and the heat transfer between the specific equipment room and the outside air can be estimated by the heat flow phenomenon in the outer skin of the specific equipment room. It is assumed that The heat flow phenomenon is a heat transfer phenomenon in a space separated by a fixed wall, and if the outside air temperature is higher than the room temperature, the air conditioning load increases due to the inflow of heat. If it is low, the air conditioning load is reduced due to the outflow of heat.

The specific equipment power consumption basic unit calculation unit 153 includes the heat transmissivity U (i) [kW / K · m ² ] of the outer skin of the sample building i, the outer skin area S (i) [m ² ], and the specific equipment room area A _m (i) [m ² ], the temperature difference ΔT (i, N) [K] between the outside temperature and the specific facility indoor temperature in N month, and the day number N (day) of N month (day) Is used to calculate the heat transfer rate Q (i, N) [kWh / m ² / month] per floor area in N month by the following equation (7). In the following equation (7), the temperature difference ΔT (i, N) [K] can be estimated using the temperature data of the area where the sample building i is installed and the recommended temperature in the building.

As described above, the specific facility power consumption _basic unit calculation unit 153 determines that the specific facility power consumption _basic unit E _{mech, B} (i) [kWh / m ² / month] and the heat flow rate Q (i, N) By dividing the sum of [kWh / m ² / month] by the monthly average value COP (i, N) of the system COP of N month, the power consumption basic unit E _air, by the air conditioning system of the sample building i _B (i) [kWh / m ² / month] is calculated as in the following equation (8).

  Thereby, the above-described equation (4) can be expressed as the following equation (9).

By converting the above equation (9), the specific facility power consumption _basic unit calculation unit 153 converts the specific facility power consumption _basic unit E _{mech, B} (i) [kWh / m ² / month] into the following equation (10 ).

In S4, the air conditioning facility power consumption basic unit calculation unit 154 of the power consumption analysis device 10 inputs the specific facility power consumption basic unit data d14 calculated in S3, and outputs the air conditioning facility power consumption basic unit data d15. Specifically, the air-conditioning equipment power consumption basic unit calculation unit 154 generates a seasonal variation power consumption basic unit E _{air, F} (i, n) [kWh / m ² / month]. The seasonal fluctuation power consumption basic unit E _{air, F} (i, n) [kWh / m ² / month] is the specific equipment room seasonal fluctuation power consumption basic unit E _{m, F} (i, n) calculated in S2. ) Corresponding to a part of [kWh / m ² / month].

The calorific value from the specific equipment corresponds to the specific equipment power consumption _basic unit E _{mech, B} (i) and is considered to be constant throughout the year. It can be considered that the seasonal variation creates the seasonal variation of the power consumption basic unit. Therefore, the air conditioning facility power consumption basic unit calculation unit 154 calculates the average value COP (i, n) of the system COP in n month and the heat per floor area in n month from the average outside temperature by month at the location where the sample building i is located. Through-flow rate Q (i, n) [kWh / m ² / month] is calculated. Further, the air conditioning facility power consumption basic unit calculation unit 154 calculates the power consumption E _air (i, n) [kWh / m ² / month by the air conditioning facility in n month for processing the air conditioning load by the following equation (11). ] Is calculated.

  Here, the air conditioning facility power consumption basic unit calculation unit 154 estimates the average value COP (i, n) of the monthly system COP from the monthly average outside air temperature using the catalog data in the same manner as in S3.

From the above, the air conditioning facility power consumption basic unit calculation unit 154 calculates the air conditioner base power consumption basic unit (air conditioning power consumption basic unit of the base power consumption basic unit) calculated in S3 and the above equation (8). The monthly fluctuation power consumption basic unit E _{air, F} (i, n) [kWh / m ² by the air conditioning equipment, as shown in the following equation (12). / Month] is calculated. The power consumption basic unit output unit 16 outputs the calculated seasonal variation power consumption basic unit E _{air, F} (i, n) [kWh / m ² / month] by the air conditioning equipment.

Next, an example of data analysis performed by the power consumption analyzer 10 will be described with reference to FIGS. 6A and 6B. FIG. 6A is a diagram illustrating input data D1 and D2 to the power consumption analysis apparatus 10. FIG. 6B is a diagram showing output data D3 from the power consumption analyzer 10. In FIG. 6A and FIG. 6B, it is assumed that the recommended temperature in the specific equipment room is 24 ° C., and the values of the skin area and the heat insulation performance are data of general buildings. When the power consumption analyzer 10 analyzes a sample building (samples A and B), as shown in FIG. 6A, building data (for example, location, specific equipment room area [m ² ], office room area [ m ² ], system COP conversion coefficient (= α), heat insulation performance [K · m ² / kW], specific equipment room skin area [m ² ]), and monthly building power consumption data [MWh / month] Are used as input data D1 and D2, respectively. In contrast, as the output data D3, as shown in FIG. 6B, the specific equipment power consumption rate and [kWh / ^{m 2} / month], an air conditioning based power consumption per unit [kWh / ^{m 2} / month], Monthly air conditioning equipment seasonal variation power consumption basic unit [kWh / m ² / month] is calculated and output.

  As described above, the power consumption analysis apparatus 10 includes the specific facility room power consumption basic unit calculation unit 151, the specific facility room power consumption basic unit separation unit 152, and the specific facility power consumption basic unit. A unit calculation unit 153. The specific facility room power consumption basic unit calculation unit 151 calculates the power consumption basic unit of the specific facility room of the building using the power consumption of the entire building and a predetermined power consumption basic unit. The specific equipment room power consumption basic unit separating unit 152 calculates the base power consumption basic unit, which is the monthly power consumption basic unit of the month with the lowest monthly power consumption basic unit. The unit is separated into the power consumption basic unit obtained by subtracting the base power consumption basic unit from the monthly power consumption basic unit (for example, seasonally variable power consumption basic unit). The specific facility power consumption basic unit calculation unit 153 calculates the power consumption basic unit by the specific facility in the specific facility room using the base power consumption basic unit and the variable power consumption basic unit obtained by the separation. .

  In addition, the power consumption analyzer 10 uses the calculated power consumption basic unit of the specific facility, the performance of the air conditioning facility of the building, and the monthly average temperature at the location of the building to It is good also as having further the air-conditioning equipment power consumption basic unit calculation part 154 which calculates a power consumption basic unit. Furthermore, the predetermined power consumption basic unit may be a power consumption basic unit of an office building based on DECC data. The specific equipment room power consumption basic unit calculation unit 151 calculates the power consumption basic unit of the communication equipment room as the specific equipment room, and the specific equipment power consumption basic unit calculation unit 153 is the communication equipment in the communication equipment room. It is also possible to calculate the power consumption basic unit.

  As described above, the power consumption analyzer 10 grasps the actual power consumption by the specific equipment based on the power consumption data of the building having the specific equipment like the communication building in which the communication equipment is installed. . In general, a building has a floor area (specific equipment room) in which specific equipment (for example, communication equipment) is installed, an office where workers of the building work, hallways and toilets, Although it can be classified as a space in which equipment is stored, the space other than the specific equipment room is not significantly different from a general office building in its use and specifications. In the power consumption analysis apparatus 10 according to the present embodiment, on the premise of this, the power consumption of the specific facility room is estimated from the power consumption data of the building by the method described above.

  Specifically, the power consumption analyzer 10 analyzes the power consumption in the building based on the power consumption of the entire building, such as the office building power consumption basic unit, air conditioner performance, and monthly average temperature by region. By using the information reported from, the power consumption basic unit of the communication equipment and air conditioning equipment in the building is calculated. In order to save power, it is effective to grasp the power consumption of the communication equipment for each office building (for example, the communication building) having different installation conditions of the communication equipment. For example, the user can easily grasp the power consumption of the communication facility from the power consumption amount information of the entire building without providing a special facility such as a sensor.

  In addition, the power consumption analysis apparatus 10 collects the estimation result as statistical information on all the buildings (for example, communication buildings) obtained as a sample, thereby providing a benchmark for evaluating the energy performance of the building. Establish. By using this benchmark, for example, the user compares the power consumption of communication facilities between multiple communication buildings, and uses the result of the comparison as an index for prioritizing measures for power saving. It becomes possible to do.
