[0002]

BACKGROUND ART Buildings have a long service life even if used for various purposes. For example, a building is 30-50
It has a useful life of about a year. On the other hand, the service life of the equipment and equipment used for the maintenance and operation of the building and the individual use purpose is about 5 to 10 years, and the building-related equipment and equipment (hereinafter, referred to as With the aging of the building-related equipment, etc.), the necessity of maintenance increases, and a new replacement (renewal) of the building-related equipment and the like is required.

[0003] However, replacing a building-related device or the like requires a large amount of construction cost when replacing the building-related device or the like, in addition to the purchase cost. For this reason, while delaying investment decision by measuring the investment timing, there is a problem that the operating environment of the building is deteriorated due to deterioration of performance of the existing building-related equipment and the like.

On the other hand, in order to protect the earth from environmental deterioration caused by global warming, reduction of greenhouse gas (dioxide gas) emission has been called for. Because greenhouse gases are emitted as energy is consumed, promoting energy conservation has become an important policy issue, and even at the level of individual buildings,
It is desirable to take comprehensive and effective energy conservation measures.

[0005] Against this background, it is one of the so-called energy saving services, ESCO (Energy Service), to realize capital investment in the building operation environment without burden by generating energy savings.
Company) business.

As a method of the energy saving service business, as shown in FIG. 1, when a target building is specified, an initial diagnosis is first performed (step S1), and the energy saving work is performed by performing the energy saving work. It is determined whether or not. Since this initial diagnosis is a means of approach from the energy saving service provider to the building operator, the initial diagnosis is free of charge and the calculation of the diagnosis cost is not performed. Output (diagnosis result report of initial diagnosis) (Step S)
Complete with 2). Then, the result of the initial diagnosis is presented to the building operator, and when the building operator obtains consent to perform the detailed diagnosis, the detailed diagnosis is performed (step S3). The detailed diagnosis is performed with the approval of the building operator and is the basis of the contract, so it is performed specifically and in detail without being bound by the initial diagnosis. Therefore, this detailed diagnosis is done for a fee,
The detailed diagnosis is completed by calculating the diagnosis cost (step S4) and outputting the medium (for example, a detailed diagnosis result report) on which the detailed diagnosis result is recorded (step S5).

As described above, since a detailed diagnosis, which is a prerequisite for the energy saving work, requires a diagnosis cost, there is a possibility that only a detailed diagnosis cost will be generated for a building operator depending on the result of the detailed diagnosis. In other words, the detailed diagnosis is performed based on the initial diagnosis, but even though the result that the energy saving work is effective in the initial diagnosis has been obtained, when the detailed diagnosis is actually performed, In some cases, detailed diagnosis does not conclude that energy saving work is effective. Up to now, in such cases, energy conservation work may not be performed, and the building operator will not enjoy the benefits of energy conservation work. Only the cost was paid. Such cases may have caused the building operator to hesitate when reviewing the initial diagnosis and approving the detailed diagnosis.

FIG. 2 is a conceptual diagram showing the operating costs of a building. In order to operate and manage buildings (especially large buildings such as government offices, public facilities, and hotels), various operation costs are required. These operating costs are:
It can be classified into several operating costs based on its type, purpose, etc. In the example shown in FIG. 2, the operation cost is classified according to the type of energy and the use of energy, focusing on the fact that the operation cost is caused by the consumption of energy required for operation of building-related equipment and the like. . Here, the primary energy classified by energy type is energy used as it is without being processed in a building, for example, electricity, gas (LP gas,
Propane gas), water, and heavy oil. The secondary energy is energy that is processed into a state that can be easily used in a building, and is, for example, steam, cold / hot water, or cold / hot air. The housing uses classified by energy use are costs used for maintaining and operating a building and for comforting people who work there, and are used, for example, for lighting and air conditioning. The production use is the energy used for the purpose of use of the building. For example, when the building itself is for the purpose of producing something (for example, a factory), it is the energy cost used for the production. is there.

The operating cost of such a building is caused by the operation of equipment related to the building, and the service life of these building-related equipment is overwhelming compared to the service life of the building itself. Short. This means that periodic replacement of equipment and the like is necessary only for maintaining and managing the building. However, even if it is known that equipment related to building needs to be replaced, financing for replacing building related equipment etc. is not left
Older equipment and facilities are more likely to be left as they are, which can lead to inefficient use of energy and worsen building operating costs.

Therefore, in the energy saving service, the costs required for replacement of building-related equipment and the like caused by aging of building-related equipment (equipment purchase cost, construction and construction cost, maintenance cost after replacement of equipment, monitoring The objective is to reduce operating costs (ie, reduce costs by introducing new equipment, etc. to save energy), assuming that the environment inside the building is not degraded. . That is, at the request of a building operator (energy saving service user) or at a proposal to a building operator, an energy saving service provider having expertise and know-how on building-related equipment and energy saving technologies is A certain rate of reduction in the amount of equipment, and undertake a series of operations and management related to the replacement of building-related equipment, etc., to reduce operating costs. The operating costs before equipment replacement (current operating costs) and the equipment after replacement The difference between the operation cost (actual operation cost) and the cost related to construction and purchase of equipment (hereinafter referred to as construction cost) is to be allocated (see FIG. 5).

FIG. 3 is a diagram exemplifying a diagnosis target portion for energy saving in a building, wherein an air conditioner,
Represents solar cells, windowpanes, lighting equipment, central monitoring systems, plumbing (water saving), substation equipment, cogeneration systems, pumps, ice heat storage, heat source equipment, etc. For example, the following can be cited as diagnostic points for energy saving. (1) Lighting system ・ Use high-efficiency fluorescent lamps ・ Change from incandescent lamps to fluorescent lamps ・ Use lighting devices with dimming function ・ Use lighting devices with manned sensors (2) Air conditioning equipment ・ Constant air volume・ Change to a variable system ・ Effective use of outside air ・ Introduction of heat exchanger ・ Effective use of ventilation (3) Heat source equipment ・ Replacement with high-efficiency equipment ・ Inverter control of chilled / hot water pump ・ Schedule control using timer (4 ) About motors ・ Replacement with high-efficiency motors ・ Inverter control (5) Central monitoring system ・ Ascertain equipment operation status and optimize operation control (6) Compressor ・ Air leakage countermeasures ・ Inverter control (7) Stabilization Power supply unit ・ Voltage drop (lighting system) (8) Demand control unit ・ Reduced contract power through operation control (9) Adoption of cogeneration system Reduction of contract power by private power generation ・ Efficient use of hot water and steam (10) Adoption of ice heat storage system ・ Use of late-night power to reduce contract power (11) Adoption of new energy ・ Solar cells, wind power generation, fuel cells The energy-saving service provider prepares an initial diagnosis report and a detailed diagnosis report as follows by checking and diagnosing these various places.

First, the overall operation of the energy saving business will be specifically described. As shown in FIG. 4, the energy-saving service provider first investigates the usage status of electricity, gas, water, heavy oil, etc., and the operation status of the facility in the building-related equipment to be targeted as an initial diagnosis (B1), and the survey result Is analyzed and evaluated to create an initial diagnosis report (B2).
Then, when the conclusion that the energy saving work is effective for cost reduction is obtained from the initial diagnosis report, the energy saving method is proposed to the building operator (energy saving service user) and the use of the energy saving service is invited.

When the building operator approves the detailed diagnosis, the energy-saving service provider installs a logger (measuring instrument) on the target building-related equipment and operates the building-related equipment and facilities. Then, data such as detailed specifications of the device is collected (B3). Then, the data is analyzed in detail, and the optimum and the best method among various energy saving measures is examined, and thereby a detailed diagnosis report is created (B4) and presented to the building operator.

When the detailed diagnostic report is approved by the building operator, a performance contract (energy saving service execution contract) and the like are concluded between the building operator (energy saving service user) and the energy saving service provider. (B5) Assured amount of energy reduction as originally planned. The energy-saving service provider is responsible for the design and construction of the energy-saving work (B6).

After the energy-saving work is performed, the energy-saving service provider monitors the building and monitors the amount of energy saving (the amount of operation cost reduction) for a certain period of a guarantee period in order to realize the above guarantee ( B
7). And by this monitoring, it is monitored that the economic effect by energy saving is obtained.

FIG. 5 is a diagram showing the guarantee contents. In FIG. 5, α represents the current operating cost within a certain period before the construction, and β represents the target operating cost defined by the contract. Therefore, this current operation cost α
The difference between the target operating cost β and the target operating cost β is the guaranteed reduction amount (estimated reduction amount) γ within a certain period. If the target operating cost β is achieved, the guaranteed amount of reduction γ will not be required as the operating cost,
The amount paid to the building operator, such as the cost of energy-saving equipment and monitoring equipment, the maintenance cost of energy-saving equipment, and the guarantee fee (monitoring cost, etc.), will be paid to the building operator. Is the profit ε of the building operator. On the other hand, the energy saving service provider will benefit from the building operator payment δ. After the warranty period has expired,
The amount equivalent to the reduction guarantee amount γ is all for the benefit of the building operator. In addition, energy saving of building-related equipment can contribute to prevention of global warming.

During the monitoring period, the energy saving service provider guarantees that the amount of energy saving (the amount of reduction in total energy consumption for one year) shown in FIG. As shown in (b), when the effect of the energy saving work is remarkable and the amount of energy saving exceeds the amount of reduction compensation, the difference becomes a benefit of the building operator.

On the other hand, as shown in FIG. 6C, if the energy saving amount is smaller than the guaranteed reduction amount, the energy saving service provider compensates the building operator for the difference. Therefore, even if the amount of energy saving is less than the guaranteed amount of reduction, the structure is such that the building operator is not lost. However, there are various methods of payment, such as when the amount of energy saving does not reach the guaranteed amount of reduction or when the amount exceeds the guaranteed amount of reduction. It is possible.

As a result, the building operator can maintain the building comfortably without having to worry about generating funds for new equipment and its construction work, and at the same time, costs more than the reduction in operating costs are generated. By being guaranteed not to do so, it is possible to request energy-saving construction with confidence.

FIG. 7 shows an environment for executing the above energy saving service. A computer 1 equipped with a building equipment reinvestment system and a computer 2 equipped with a building operation system are connected through a network 3 such as the Internet or an intranet. The computer 2 equipped with the building operation system is installed on the building, and before the construction, data for calculating the current operation cost is obtained, and after the construction, data for calculating the actual operation cost is obtained. In order to obtain such information, the operation status of building-related equipment is automatically monitored. Monitoring information such as the operation status of building-related equipment and the like monitored by the computer 2 is transmitted to the computer 1 through the network 3 and is input to the building equipment reinvestment system. The various output media 4 such as a monitoring result recording medium which is made into a database in the building equipment reinvestment system can be output on the computer 1 side, but can also be output directly on the computer 2 side as the output medium 5. .
Of course, the operation status of the building before and after the construction may be manually monitored, and the monitored situation may be manually input to the building equipment reinvestment system.

FIG. 8 shows the building equipment reinvestment system 11 described above.
FIG. 2 is a functional block diagram showing the configuration of FIG. The building equipment reinvestment system 11 referred to here is intended to improve the operation cost by managing from the energy saving diagnosis of the building to the design, construction, maintenance, and monitoring, and to propose financing and reduce the operation cost. A system for proposing and executing guarantees. As shown in FIG. 8, the system 11 includes a man-machine input unit 12, a man-machine output unit 13, and a processing unit 1.
4. The storage unit 15 stores a database. The man-machine input unit 12 is a part for an operator of the system 11 to input, for example, a keyboard, a numeric keypad,
Any type, such as a mouse, a switch (including a function switch, etc.), and a voice input microphone, can be used as long as the input of the operator is transmitted to the system 11. The man-machine output unit 13 is a unit for outputting information to an operator of the system 11, and outputs an output to the operator from the system 11, such as a display, a lamp, a speaker for audio output, a printer, or the like. If
The type does not matter. The processing unit 14 processes input information from the man-machine input unit 12, processes output information to the man-machine output unit 13, processes input / output information with the storage unit 15,
A portion that executes processing of input / output information with the external device 17 through communication means such as the network 16 and is configured by an arithmetic unit (CPU). Note that, in some cases, some of the functions of the processing unit 14 may be performed manually outside the system. The storage unit 15 is a so-called database, and the processing unit 14
From the man-machine input / output units 12, 1
3 stores input / output information with the external device 17 and outputs the stored input / output information in response to an instruction from the processing unit 14.

The building equipment reinvestment system 11 and the external equipment 17 are not limited to the method of indirectly connecting them with the network 16, but may be directly connected using a cable or the like.
Further, the network 16 is a so-called communication means, and a suitable one may be selected and used according to the use of the system 11. The external device 17 is a device for mutually transmitting and receiving input / output information with the system 11, and is, for example, another system, a printer, or the like. Note that the word “information” used here may be replaced with the word “data”. Further, the man-machine input / output units 12 and 13 do not need to be inside the system 11 as shown in FIG. 8, and may be independent of the system 11 and serve as terminals for the system 11. 16 may be connected.

By the way, after the construction of the energy-saving work, as mentioned above, a guarantee is made through the supplement from the energy-saving service provider so as not to bring a disadvantage to the building operator. Since a detailed diagnosis requires a diagnosis cost, conventionally, depending on the result of the detailed diagnosis, the building operator may only incur the cost of the detailed diagnosis. That is,
The result of the initial diagnosis was that the energy-saving work was effective.If a detailed diagnosis was made and it was not concluded that the energy-saving work was effective unlike the initial diagnosis, the building operation May only pay the cost of a detailed diagnosis.

Therefore, the present invention employs a mechanism that does not cause a loss to the building operator according to the result of the detailed diagnosis. FIG. 9 is a diagram for explaining this mechanism. FIG. 9A shows the energy cost at the time of initial diagnosis and detailed diagnosis (before energy saving work). In the initial diagnosis, the amount of reduction in energy cost is estimated for the time being. Then, as shown in FIGS. 9B and 9C, the estimated amount of reduction at the time of the initial diagnosis is given a range, and is guaranteed as an estimated range (guaranteed range) of the cost reduction amount in the detailed diagnosis. As a result of the actual detailed diagnosis, an estimated value of the cost reduction amount by the detailed diagnosis is calculated. Usually, the estimated value of the cost reduction amount of the detailed diagnosis is calculated as shown in FIG. Within the estimated range of cost savings.
However, if the estimated value of the cost reduction amount by the detailed diagnosis falls below the lower limit of the estimated range of the cost reduction amount of the detailed diagnosis as shown in FIG. Reduce the cost of diagnostics by reducing the burden on building operators, or make them free (free) so that they are not burdened by building operators. Therefore, by assuring this, building operators will be more likely to undergo detailed diagnosis,
The use of energy-saving services can be promoted.

FIG. 10 is a flowchart showing a flow from the execution of the initial diagnosis to the presentation of the detailed diagnosis result in the embodiment of the present invention. As shown here, when the target building is specified, an initial diagnosis is performed (step S1).
1) When the initial diagnosis is completed, an estimated range of the detailed diagnosis is calculated (step S12), and an initial diagnosis result medium is output (step S13). Next, when the initial diagnosis result is approved, a detailed diagnosis is performed (step S14). When the detailed diagnosis is completed, a diagnosis cost is calculated (step S15), and a detailed diagnosis result medium is output (step S16). Less than,
The processing content of each step will be described.

First, in the execution of the initial diagnosis shown in FIG. 10 (step S11), as shown in FIG. 11, an instruction to start the initial diagnosis is issued from the man-machine input unit 12 while executing other processing in response to a request. It waits until an input is made (steps S21 and S22). If there is an instruction to start the initial diagnosis by input from the man-machine input unit 12 (YES in step S21), the entry format of the initial diagnosis is read from the database (step S21). S23), and outputs the read entry format to the man-machine output unit 13 (step S23).
24). When the entry format is output from the man-machine output unit 13, for example, in the form or data of a printed document, a person in charge of initial diagnosis investigates and fills out each item, and inputs the investigation result into the man-machine input unit. Input from 12. Based on the initial diagnosis (estimated)
Cost savings are also included. The building equipment reinvestment system 11 waits while performing other processing according to the request until the initial diagnosis result is input (Step S2).
5, when the initial diagnosis result is input from the man-machine input unit 12, the initial diagnosis result is stored in the database (step S27).

Next, in the calculation of the estimated range of the detailed diagnosis in FIG. 10 (step S12), as shown in FIG.
The initial diagnosis result is read from the database (step S31), and the estimated range (minimum value to maximum value) of the cost reduction amount at the time of detailed diagnosis is calculated from the read initial diagnosis result (step S32). Is stored in the database (step S33). Here, the estimated range of the cost reduction amount at the time of the detailed diagnosis is the estimated range of the cost reduction amount indicated by the detailed diagnosis result (the minimum reduction amount) determined based on the (annual) cost reduction amount calculated in the initial diagnosis. ~ Maximum reduction). That is, the estimation range of the detailed diagnosis is a range in which the amount of cost reduction based on the result of the initial diagnosis is varied.

In the output of the initial diagnosis result medium of FIG. 10 (step S13), as shown in FIG. 13, the initial diagnosis result is read from the database (step S41).
The read initial diagnosis result is output from the man-machine output unit 13 as an initial diagnosis result medium in a predetermined format (step S42). This medium is generally a printed matter output from a printer or the like, but may be an electronic medium such as a floppy (registered trademark) disk or MO. FIG. 14 shows an initial diagnosis result report as an example of such an initial diagnosis result medium. Here, the annual reduction amount is described for each energy reduction item, but the range of the total amount of the annual reduction amount is the estimation range of the detailed diagnosis (see FIG. 9).

The thus outputted initial diagnosis result medium (for example, an initial diagnosis result report) is presented to the building operator. When the building operator examines the contents of the initial diagnosis result medium, the initial diagnosis is accepted by the building operator, and the implementation of the detailed diagnosis is approved, an instruction to start the initial diagnosis is sent to the building equipment reinvestment system 11. Is entered.

The detailed diagnosis shown in FIG. 10 is performed (step S1).
In 4), as shown in FIG. 15, the building equipment reinvestment system 11 is on standby while executing other processing according to the request (steps S51 and S52). If there is an instruction to start diagnosis (YES in step S51), the entry form for detailed diagnosis is read from the database (step S53), and the read entry format is output to the man-machine output unit 13 (step S54). Thus, for example, when an entry form output in the form of printed documents or data is output as it is, each item is entered based on the diagnosis result of the detailed diagnosis. When the data of each item related to the detailed diagnosis is obtained, the data (the detailed diagnosis result) is input into the
2 is input. The building equipment reinvestment system 11
The apparatus is on standby while performing other processing in response to the request (steps S55 and S56). When the detailed diagnosis result is input from the man-machine input unit 12, the detailed diagnosis result is stored in the database (step S57).

Calculation of diagnosis cost in FIG. 10 (step S1)
In 5), as shown in FIG. 16, the initial diagnosis result is read from the database (Step S61), and the estimated range of the cost reduction amount in the detailed diagnosis from the read initial diagnosis result (hereinafter referred to as the estimated range of the detailed diagnosis). ) Is extracted (step S62), and the extracted estimated range of the detailed diagnosis is temporarily stored in a database (step S6).
3). Thereafter, the stored estimated range of the detailed diagnosis and the detailed diagnosis result are read from the database (steps S64 and S64).
65) Then, the cost of the detailed diagnosis is calculated based on a predetermined standard (step S66) and stored in the database. Next, the estimated range of the detailed diagnosis is compared with the detailed diagnosis result (step S67), and it is determined whether the estimated reduction amount based on the detailed diagnosis result is smaller than the lower limit of the estimated reduction amount in the estimated range of the detailed diagnosis (step S67). S68). If the estimated reduction amount of the detailed diagnosis is equal to or larger than the lower limit of the estimated reduction amount, the diagnosis cost calculated in step 66 is determined.
On the other hand, when the estimated reduction amount of the detailed diagnosis is smaller than the lower limit value, the diagnosis cost is reduced or made free according to a predetermined standard (step S69), and the reduced diagnosis cost or the free diagnosis cost is reduced. It is stored in the database as a new detailed diagnosis cost (step S70).

In the output of the detailed diagnosis result medium of FIG. 10 (step S16), as shown in FIG. 17, the detailed diagnosis result and the diagnosis cost are read from the database (step S71), and the read detailed diagnosis result and the diagnosis cost are read. Is output from the man-machine output unit 13 as a detailed diagnosis result medium in a predetermined format (step S7).
2). This medium is generally a printed matter output from a printer or the like, but may be an electronic medium such as a floppy disk or MO. FIG. 18 shows a detailed diagnosis result report as an example of such a detailed diagnosis result medium. Here, the detailed diagnosis cost is also specified.

By operating the energy saving service in this way, even if the result of the detailed diagnosis is unsatisfactory from the initial diagnosis result, it is possible to obtain the understanding of the building operator or to obtain the understanding of the building operator. You can avoid disadvantages.
