JP5777923B2 - Resource-saving / energy-saving evaluation operation system - Google Patents

Description

  The present invention relates to a resource saving / energy saving evaluation operation system that is easy to introduce and has high resource saving / energy saving effect.

  In order to respond appropriately to global environmental problems such as carbon dioxide reduction, the public and private sectors will save resources and energy (resource savings and energy include energy, water and waste utilization projects in addition to energy) It is necessary to develop equipment that contributes to energy conservation).

  Therefore, the government has developed various measures such as subsidizing funds, amending the Energy Conservation Law, and utilizing the CDM (Clean Development Mechanism) market, and has put out various measures while drawing out the vitality of the private sector.

  However, while private companies recognize the importance of global environmental problems, in reality, it is difficult to make capital investments that are difficult to generate direct profits as international competition intensifies.

  For this reason, there is an urgent need to develop an energy-saving evaluation operation system as a new business model that makes it easy for private companies to make “energy-saving investments”.

  One of them, which is an invention that aims to save energy in a water purification system, is provided in a facility that receives power from the outside, and for the purpose of operating and controlling a purified water device that purifies raw water using electric power, Received power amount detecting means for detecting the received power amount that is receiving power, integrated used power amount predicting means for predicting an integrated amount of used power within a predetermined time based on the detected received power amount, and the purified water device The tank water level detection means for detecting the tank level of the purified water tank that stores purified water purified from the outside and clean water received from the outside, and the predicted integrated amount of the used power exceeds the preset upper limit of the used power amount And within a range, the purified water device control means for driving and controlling the purified water device so as to ensure the target water level set in advance, and the water level below the preset lower limit water level If the the operation control device for purifying water apparatus provided with a water supply receiving valve control means for opening control clean water receiving valve receiving clean water is known from the outside (Patent Literature 1).

JP 2005-52792 A

  In Patent Document 1, attention is paid only to the cost related to the power charge, and there is no description about the cost calculation related to financial engineering from the standpoint of energy saving.

As an example of a normal energy-saving contract, assuming that the energy-saving business operator is “A” and the customer group is “B”, it is as follows.
1) Party A will use the energy-saving technology of Party A to lower the utility bills from 140 million yen per year to 100 million yen.
2) Party A and Party B will conclude a long-term energy saving business contract such as 15 years. As a result, the total energy saving effect during the project period will be 600 million yen.
3) Party A and Party B agree to spend 200 million yen as necessary capital investment out of the 600 million yen reduction effect of 1).
4) As a result, Party A and Party B divide the remaining 400 million yen by 200 million yen each.

  In other words, energy-saving business operator A and customer B cooperate to produce “energy-saving benefits” through long-term energy-saving contracts and halve them with certain rules. , You don't need to make money. Therefore, since there is no burden on the second party, the customer base will expand and energy conservation in Japan and the world will proceed.

  However, there are two problems with this contract model, and in order to promote energy conservation, it is necessary to develop a solution that incorporates financial engineering.

  The first problem is that, in the concept of the normal energy saving contract, the energy saving equipment provided by the energy saving business operator A will ultimately belong to the customer (“on balance”) for accounting purposes. If it becomes on balance, B will give priority to the main business equipment, and eventually it will postpone energy-saving equipment.

  The second problem is that when the energy saving business operator A enters into a contract that undertakes most of the business risks in order to make “energy saving investment” on behalf of the customer B, Increase, and the balance of the financial structure of the former will worsen. In the end, it is a limit to the financial strength of our company, and it is difficult to save energy.

  The energy saving evaluation operation system of the present invention was invented by utilizing financial engineering in order to solve the above two problems simultaneously while promoting energy saving.

In order to solve the above two problems, the present invention is an energy-saving evaluation operation system of an energy-saving facility using a computer for a facility equipped with facilities that operate by power such as electricity, gas, water, and wind power. equipped with a data base and benefits calculation means, the facility is shared by the energy-saving facilities and energy-saving system operators, to the data base to share or purchase of the equipment can be recorded as expenses should be recorded as an asset for the facility wherein is data that can be determined is recorded based on the prevalence of the equipment, the benefit calculation means when the prevalence of the installation according to the facility is determined to be recorded as expenses utilization of the equipment below a predetermined value Costs required for operating equipment, such as equipment purchase costs, operating costs, and interest rates, are reduced by energy conservation. The computer compares the cost, and the computer has a search means for acquiring objective data with an Internet search engine, a maintenance data acquisition means for acquiring maintenance data of the facility as subjective data, and the objective Evaluation means for evaluating and predicting the market value of the equipment in real time by linking data and subjective data, and the search means includes at least energy cost data and weather prediction data, and the maintenance data acquisition means Includes at least an energy-saving facility operation database operated by a special purpose company, and the evaluation means includes at least replacement-date determination data for the energy-saving facility, and is used to calculate future utility costs for a plurality of equipment groups. Calculation of profit and loss is possible, and based on the result, energy-saving facilities can be converted into credits To.

  Here, subjective data is a cost that can be predicted without objective data. For example, it means metered utility costs. Objective data is the future of subjective data. Parameter data that contributes to fluctuations, such as weather forecast data and crude oil price trend forecast data.

  In the present invention, “on balance” refers to a state described on a balance sheet (balance sheet), and “off balance” refers to an off balance sheet, which means a state that is not placed on a balance sheet.

  If the balance is reduced and the assets and liabilities of customer B are reduced, the assets become sound and the asset efficiency is improved.

  In the past, the scheme of on-balance when purchasing equipment and off-balance when borrowing with a lease contract was established. However, the accounting standards for lease transactions were revised in April 2008, and even finance lease transactions that do not transfer ownership It was decided not to allow off-balance processing, but to carry out on-balance processing that would be recorded on the balance sheet as if the asset had been fully purchased.

Therefore, instead of leasing, the energy-saving system trader A has a certain level of energy-saving equipment and contracts to receive service fees from the customer B, so that the expenses related to the equipment will not be listed on the customer's balance sheet.
Furthermore, the energy-saving system trader A develops special financial products using financial engineering to solve the problem that the assets of Party A increase as the number of energy-saving projects increases. That is, by utilizing the energy saving evaluation operation system of the present invention, a data group such as capacity guarantee data of energy saving equipment and objective recording data of the energy saving effect is prepared for each individual energy saving business. Then, the financial engineering optimizes the combination of multiple energy-saving businesses and makes them special financial products. In addition, the Company sells the special financial product to banks and special purpose companies (hereinafter referred to as “SPC”). We will continue to add new energy-saving projects by utilizing the profits from the sale.
Furthermore, by connecting the energy saving evaluation operation system of the present invention via a network, a new type of securities market can be constructed if the total of the special financial products reaches about 100 billion yen. As a result, the energy-saving system trader A can procure funds from the market through SPC and the like, and the energy-saving business will expand dramatically. As a result, there is a system in which all citizens can participate in energy conservation.

The present invention is an invention from a financial engineering standpoint, and is not limited to merely analyzing financial data (subjective data), but also data such as weather forecast information, second-hand market trends of operation equipment and energy market conditions (objective data). Is an invention related to a computer system that calculates future profit forecasts, considering equipment-related costs as subjective data, forecasts of electricity consumption fluctuations due to weather fluctuations, fluctuations in light and heat costs due to fluctuations in crude oil prices, etc. The objective of this study is to disseminate energy-saving equipment by off-balance the energy-saving equipment, assuming that second-hand market price trends, etc. when assuming that the equipment in operation is sold are objective data. This has the effect of reducing emissions.
Furthermore, special financial products will be created by using financial engineering to combine multiple energy-saving businesses.

It is the figure which showed the block diagram of the comprehensive control server. It is the figure which showed one example of the facility group. It is the figure which showed the financial engineering cost structure by this invention. It is the figure which showed the information source of the calculation means. It is the figure which showed the information source of the search means. It is the figure which showed the maintenance data acquisition means. It is the figure which showed the information source of the evaluation means.

  FIG. 1 is a diagram showing a configuration diagram of the integrated control server. The central control server 1 records a CPU device 2 having a central processing element, an operation database 3 for storing various databases, and a corporation as a user-oriented entity as an asset when introducing an energy saving system. The calculation means 4 for calculating both the on-balance cost and the off-balance cost to be recorded as an expense, the search means 5 for acquiring predetermined data by an Internet search engine, and the maintenance data acquisition means 6 for the corporation And an evaluation means 7 for evaluating the market value of the equipment to be used in real time, and an interface 8 for external data acquisition and data communication.

  The computer of the general control server has a database and merit calculation means, and the database records data for determining whether the purchase of the equipment should be recorded as an asset or as an expense for the facility. When it is determined that the purchase of the equipment can be recorded as an expense, the calculation means compares the expense necessary for operating the equipment, such as the equipment purchase cost, operation cost, and interest rate, with the cost reduced by energy saving.

  The CPU device 2 is provided with a monitoring control function, and receives data from a power saving control system provided at a plurality of bases such as hospitals, welfare facilities and other energy saving management facilities via the interface 8, and is integrated. To save energy.

  On the other hand, the CPU device 2 receives real-time data such as satellite weather data and predicted data obtained by processing various weather data via the interface 8 and stores them in the operation database 3.

  In addition to the above, the operation database 3 includes at least the balance sheet data of the facility, the tangible fixed assets included in the balance sheet, and the utility costs in the selling and general administrative expenses in the profit and loss calculation table. .

  In the above, on-balance refers to the recording of expense items in the income statement on the balance sheet, and off-balance refers to assets / liabilities used in business operations, but not on the balance sheet. This is the recording of expense items in the income statement that are not recorded.

  Unlike the conventional lease on balance, the on-balance cost accounting according to the present invention is not a finance lease transaction that does not transfer ownership. In other words, the energy-saving system operator “A” owns the energy-saving equipment and becomes the main payer of utility bills, so that the customer “B” pays the service fee to A.

  As the customer B, it is not the purchase of the equipment, but is in the position to receive the service, so it is not recorded as an asset for the equipment, and the amount of the service fee to be paid monthly is set to an amount that does not exceed the amount saved by the utility bill according to the present invention The

  Further, the search means 5 is provided with a sensor in which various search thirds are set in the Internet search engine, and the environment received by the facility by making a long-term weather forecast or disaster forecast from the weather forecast or disaster information. Information about any fluctuations can also be stored in the database.

  If it can be predicted that sunshine hours will tend to increase, it is predicted that the amount of in-house power generation by solar power generation will increase, and if the probability of strong winds increases, the amount of power generation by wind power generation may increase. Get higher.

  The maintenance data acquisition means 6 of the corporation obtains data related to the maintenance of energy-saving equipment provided to the relevant facilities such as lighting equipment, air conditioning equipment, heat source equipment, watering equipment, water and sewage equipment, solar power generation equipment, wind power generation equipment, etc. Get in real time.

  As a result of the above, it is possible to predict the current status and future value change of the asset value and utility costs of the equipment at the target facility, and the business when all the equipment and maintenance costs of the facility are leased It becomes possible to quantify the overall evaluation value in real time.

  FIG. 2 is a diagram showing an example of a facility group. In the present embodiment, each facility group has a hospital as a core, and hotels, day care centers, geriatric health facilities, schools, public facilities, and commercial facilities cooperate with each other by supplying power.

  The power supplied from the batteries of the regular storage battery equipment installed in each facility for the purpose of energy saving is preferentially distributed to the operating room of the hospital as an emergency in the event of an earthquake, etc., through the interchange of the system. The By combining the power supply and energy saving system organically, it will be several times more important at important bases compared to a single emergency storage battery facility, and will help save lives in an emergency.

  It is conceivable to use general-purpose lead-acid batteries or lithium-ion batteries as batteries for regular storage battery facilities, but in addition to this, used lithium-ion batteries used in electric vehicles can be reused as the power source for charging stations. Conceivable.

  In this case, if the lithium battery is over-discharged, the cobalt of the positive electrode is eluted or the copper of the negative electrode current collector is eluted, so that it does not function as a secondary battery. -Since heat is generated due to destruction of the crystal structure and metallic lithium is deposited on the negative electrode side, a protection circuit for monitoring charge / discharge is necessary to ensure safety.

  In order to effectively use the battery of emergency storage battery equipment, it is necessary to use a voltage close to overdischarge as much as possible, but a storage battery (12V) having a rated voltage that is several V lower than the rated voltage (eg 330V) of the lithium battery. It may be configured by connecting the units in parallel.

  By connecting the lead storage battery and the lithium battery in parallel so that the use voltage range from the overcharge region voltage (12.6V) to the overdischarge region voltage (12V) of the lead storage battery in the lithium battery is, for example, the 300V unit. For example, since it can be used from 300V to 312V, 25 lead storage batteries may be connected in series.

  To determine the life of a lead-acid battery or a lithium battery, use a current sensor such as a Hall element in each unit (for example, the 300V unit). Can be easily reused.

  FIG. 3 shows a financial engineering cost structure according to the present invention. In the present invention, the equipment-related costs are regarded as fixed costs, the electricity consumption fluctuation forecast due to weather fluctuations, the fluctuation of light and heat costs due to crude oil price fluctuations, etc. and the second-hand market price trend when it is assumed that the equipment in operation is sold. Are regarded as variable costs.

  The curve a represents the average (for example, the previous year's performance) of the utility bill before introducing the energy saving system, and this amount becomes a standard for evaluating the degree of energy saving.

  The dotted line curve b shows the payment amount based on a general contract with the customer B after the introduction of the energy saving system at each facility. This amount is fixed by the contract, and the accumulation of the difference between the curve a and the curve b becomes a direct saving amount by energy saving. Curve b is calculated at a fixed amount based on the depreciation of energy saving equipment.

  A curve c is a curve of the utility bill that has become cheaper due to saving, and is the amount that the customer B pays to the energy saving system trader. The difference between the curve a and the curve c is the energy saving benefit. In this case, the curve c is not determined based on the depreciation cost, but is determined by accumulating from the project in which the facility optimally controls the facility and comprehensively saves energy. In addition, the input and output of resources and energy in the facility are automatically selected optimally based on judgment by a computer, so that there are a plurality of them, and they are not provided for a single customer. As a result, the equipment does not belong to the customer B but belongs to the former B, and is off-balance for the customer B.

  Curve D is the equipment value of the equipment on the books operating at the facility, and a fixed amount or a fixed amount is depreciated from the purchase amount every year as a depreciation expense.

  Curve d is the market price in the secondhand market for the equipment on the books that are operating at the facility, and the price fluctuates depending on the economic environment and the market distribution amount of secondhand goods. If the contract between the facility owner customer B and the energy saving system supplier A is temporarily cancelled, it is possible to sell at this used price. In addition, when a malfunction occurs in the facility in the middle of the contract, it may be possible to purchase and procure from the used equipment market instead of purchasing a new expensive new article.

  FIG. 4 is a diagram showing an information source of the calculation means. The calculation means 4 performs on-balance and off-balance accounting calculations related to expenses including depreciation costs for equipment and machinery installed in the managed facilities, and utility costs such as electricity rate data, water rate data, and gas rate data. Have a role to calculate in both.

  Here, by considering the curve b in FIG. 3 as income and the curve c as expenditure, it is possible to calculate the profit breakpoint using the energy saving evaluation operation system.

  The expenditure is divided into a fixed cost and a variable cost, and the fixed cost in the present invention is a cost whose amount is determined by a contract or the like and is a cost that does not vary in an economic environment or the like. Specifically, this refers to equipment depreciation and other expenses, and means costs that do not change unless the contract is renewed.

  The variable cost in the present invention refers to a cost at which the cost fluctuates according to changes in the natural environment, the economic environment, and the like. Specifically, crude oil price forecast data, coal price forecast data, average price fluctuation forecast data, and the like are external parameters that change the fixed cost.

  In the present invention, utility costs are also included in variable costs, and costs can be reduced by promoting savings for gas, water and electricity.

  As for gas, it is possible to reduce gas consumption by preventing the temperature drop at night by heating the heat storage material using sunlight from part of the gas heating.

  About water supply, we can lower water rate by promoting recycling of water by activated sludge method with submerged membrane (RO reverse osmosis membrane) and prepare for emergency by using groundwater together You can also.

  As for electricity, it is possible to promote energy saving as a result by using solar power generation or wind power generation as appropriate and reducing costs.

  FIG. 5 is a diagram showing information sources of the search means. The search means 5 acquires predetermined data with an Internet search engine. The search contents may include the company's stock price related to utility bills, second-hand market prices for equipment similar to the equipment used in related facilities, and market price trends for oil and coal.

  The search object of the search means includes prediction index data as objective data, which includes at least data on energy costs including oil, coal and natural gas, and weather prediction data around the energy saving facility. .

  FIG. 6 is a diagram showing maintenance data acquisition means. Examples of maintenance targets include cost amortization, water and utility costs, solar power generation, wind power generation, and the like regarding facilities of the facility group centered on the hospital.

  If you are entrusted with all the utilities related to water and utility bills by contract, long-term energy conservation measures can be taken, so even if the facility manager itself does nothing, at the expense of the energy conservation business promoter, for example By switching all bulbs and fluorescent lamps to LED lighting, the entire 15-year project can benefit from energy saving.

  FIG. 7 is a diagram showing an information source of the evaluation means. The evaluation means 7 includes at least replacement date determination data for the energy saving facility.

  The evaluation means 7 evaluates the market value of the equipment used in real time. This is an asset in the second-hand market for energy-saving equipment provided to the relevant facilities, such as lighting equipment, air conditioning equipment, heat source equipment, water supply equipment, water and sewage equipment, solar power generation equipment, wind power generation equipment, etc., using the Internet as an information source. Based on the value information, the current evaluation value of the equipment provided in the corresponding facility is calculated in real time.

  The evaluation means 7 uses maintenance data acquisition means for acquiring maintenance data of the corporation as subjective data and search means for acquiring prediction index data as objective data with an Internet search engine. By linking data and subjective data, the market value of the equipment used can be evaluated and predicted in real time.

  Data is automatically searched by setting a sensor for a predetermined keyword using a search engine using an Internet search engine, and the obtained data is automatically input to a computer.

  For example, to find the second-hand market prices for air-conditioning equipment, search for the model name of a specific equipment using an Internet search engine, create a database of price information on auctions and used equipment sales sites, and normalize these data. By generating a standard normal distribution according to the years of use and calculating the center value and the standard deviation, the approximate value can be known from, for example, the average value and the 3-sigma value.

  In addition, the standard normal distribution according to the years of use makes it possible to infer the actual useful life in the market. For example, when the second-hand market price falls below 20% of the standard price, it is determined that it is time for replacement. Then, it can be used as replacement date judgment data for energy-saving facilities.

  With the above technology, it is possible to calculate profit / loss for the equipment of a specific facility by the difference between the book valuation amount based on book depreciation and second-hand market price prediction and the amount available for sale.

  In addition, with regard to utility water costs, future utility costs may be calculated based on the actual cost payments at the facility and future forecasts of utility costs based on fuel price forecast data such as crude oil and coal. it can.

  Therefore, the energy saving system trader A can convert the energy saving equipment group into a loan based on the calculation of profits and losses of future utility bills. Then, it is possible to establish an SPC and purchase the former credit by SPC.

  SPC will receive monthly utility bills from Party A instead of taking the appropriate equipment from Party E.

  SPC can issue securities and create an energy-saving securities market if the amount of receivables reaches 100 billion yen. By using this resource, it is possible to procure working capital for the first two years, for example.

Furthermore, SPC will be able to enter the CDM market related to CDM, which is one of the “Kyoto Mechanisms” and is defined in Article 12 of the Kyoto Protocol.

According to the present invention, it is possible to perform an energy saving simulation of a specific facility group by using an energy saving numerical technique, and it is possible to estimate a profit reduction ratio by evaluating a technology and a business plan based on operation result data of an existing facility.

  Since the energy-saving evaluation operation system in the present invention is an automatic system using a computer, it is possible to construct a system for automatically authorizing a scheme in the CDM market by using the data on the calculation of the profit reduction ratio.

  By using the energy saving evaluation operation system of the present invention, it becomes possible for a facility such as a hospital to introduce an energy saving system without investing in an energy saving system having a large initial investment by itself. Since large-scale energy saving can be realized, it is possible to contribute to the industry by reducing carbon dioxide emissions.
