Description

  The present invention relates to a balance evaluation system relating to energy cost and environmental load suppression, a server used in the system, and a program thereof.

  In the past, companies have been conducting business activities using energy such as electricity, gas, oil, coal, and water. Many companies are concerned about the cost of these energy and have been eager to reduce costs per unit of energy.

  As a result of many years of cost-oriented energy supply, environmental issues such as global warming have become an international issue, and measures such as the Kyoto Protocol have become necessary worldwide.

  For this reason, in order to preserve the environment, for example, it is changing to determine the environmental conservation cost by policy, such as a carbon tax, and calculate the tax burden. For this reason, as in the prior art, it is necessary to pursue the best balance of energy use in consideration of not only costs for producing energy, but also environmental conservation costs and environmental restriction conditions. (See Patent Document 1). In this regard, an energy management system has been reported that can provide inexpensive energy to consumers in consideration of carbon dioxide emissions associated with energy consumption, and can reduce the labor of energy suppliers (see Patent Document 1). . Also, reports on environmental management systems that monitor and control the operating status of energy consuming equipment such as lighting equipment, air conditioners, home appliances, water heaters, and IT equipment installed in areas where environmental management activities are carried out Yes (see Patent Document 2).

Furthermore, a method for calculating the compensation according to the energy saving effect achieved by introducing equipment such as an environmental impact assessment system (see Patent Document 3) and cogeneration has been reported (see Patent Document 4). In addition, there has been reported an energy management network system that centrally manages electric power and heat generated using natural and unused energy sources and contributes to environmental conservation (see Patent Document 5).

  However, energy consumption varies greatly depending on weather conditions. In addition, as represented by hydroelectric power generation, an energy generation method that is advantageous both in terms of environment and cost varies depending on weather conditions. In addition, there are fuels such as oil, whose international market price fluctuates greatly. In this respect, it is desirable to have a system that can cope with medium- to long-term facility planning and cope with situations that vary from day to day.

  An object of this invention is to provide the balance evaluation system regarding energy cost and environmental load suppression from this viewpoint, the server used for the said system, and its program.

  In order to solve the above-mentioned problems, the inventor quickly collects information on weather conditions, fuel prices, environmental administration and the conditions that fluctuate from day to day, and evaluates the balance between energy cost and environmental load suppression based on the collected information. The following invention was made paying attention to what should be done.

The prediction date for which the user of the balance evaluation system intends to predict the balance evaluation is input. The agent means obtains information including the weather forecast data for the forecast date entered, the fuel cost forecast data, and legal constraint conditions via the communication line. In addition, based on the past actual energy consumption data stored in advance in the energy consumption data storage means and the obtained weather forecast data, fuel cost forecast data, and legal constraint conditions, the usage amount calculation means can calculate the forecast date. Calculate energy usage. The cost calculation means calculates the cost based on the energy usage amount on the prediction date and the fuel cost prediction data.

On the other hand, if it is in a position where it is necessary to make an environmentally conscious decision, it is possible to make a selection not to suppress the environmental load with the cost in mind.

  In particular, energy consumption varies greatly depending on the month, such as in Japan, where the weather changes greatly depending on the month. That is, the demand for air conditioning increases in July and August when the temperature is high. In this case, since current technology is mainly cooling by electricity, it is predicted that the amount of power energy used will increase. On the other hand, heating is necessary in the winter months such as January and February when the temperature is low, but heating is technically possible by a method using electric power and a method using gas and oil. In this case, it is desirable to be able to calculate which is the appropriate balance from the viewpoint of energy cost and environmental load control.

  In Japan, the power generation capacity of solar power generation, wind power generation, and hydropower generation is greatly affected by the season. On the other hand, it is desirable for a company having these facilities to use these power generations in terms of cost and environment. It is possible to judge whether it is advantageous in the long run by simulating the cost and environmental load suppression when assuming that these facilities are provided.

  Simulate the long-term balance evaluation program related to the invention described in (7) every month of the year, and consider the month when the energy use is the maximum, the month when the environmental load is worst, the average of the year, etc. It is possible to formulate an energy plan that takes into account the long-term environmental impact of the relevant business.

  According to the present invention, weather forecast data, fuel cost forecast data, and date information entered by the user regarding legal constraint conditions can be obtained via a communication line, so that necessary energy, cost, and environmental load suppression are appropriately calculated. can do. The operator can choose to minimize the cost within the scope of legal restrictions if the cost is important in view of the calculation result. In addition, when it is determined that environmental load suppression is important even if some costs are incurred, it is possible to select to minimize environmental load suppression.

  In addition, a long-term balance evaluation program according to the invention described in (7) is simulated every month of the year, and the month in which energy use is maximized, the month in which environmental load suppression is worst, It is possible to make an energy plan that takes into consideration the long-term environmental impact reduction of the relevant business.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. This is merely an example, and the technical scope of the present invention is not limited to this.

  The display unit 140 displays the cost calculated by the cost calculation unit and the environmental load suppression calculated by the environmental load suppression calculation unit. The display means 140 can be realized by a cathode ray tube display, a liquid crystal display device, or the like that is employed in a commercially available workstation.

  The storage means 150 has energy consumption data storage means for storing past energy consumption performance data in advance. The storage unit 150 can be realized by a hard disk, a semiconductor memory, or the like employed in a commercially available workstation.

  The input unit 160 is a unit that inputs a prediction date for which a balance evaluation is to be predicted, and can be realized by a keyboard or the like employed in a commercially available workstation.

  As shown in FIG. 2, the agent means is stored in the storage means 150 and is read by the control unit 130 when the power is turned on and operates by the weather forecast agent 132, the fuel cost agent 134, and the legal regulation agent 136. The side is composed. On the other hand, an agent corresponding to each agent is provided at each site.

  That is, a weather forecast data agent 710 is provided in the weather forecast site 700 corresponding to the weather forecast agent 132. These are connected to each other via the public communication unit 110 and the public communication line 600. The weather forecast agent 132 and the weather forecast data agent 710 are preloaded with programs that enable the weather forecast agent to acquire information necessary for balance evaluation such as temperature, humidity, and weather. Details are described in, for example, the Institute of Electronics, Information and Communication Engineers “How to make an agent system” edited by Tetsuo Kinoshita, Corona, and the like.

  Similarly, the fuel cost site 800 is provided with a fuel cost prediction data agent 810 corresponding to the fuel cost agent 134. The fuel cost forecast data includes forecast data for fuel costs such as crude oil, heavy oil, natural gas, coal, and hydrogen gas.

  Further, corresponding to the legal regulation agent 136, the legal regulation site 900 is provided with a legal regulation agent 910, a greenhouse gas agent 920, a carbon tax agent 930, and the like. Legal regulatory sites include those related to the Ministry of the Environment, as well as those related to prefectures. This is because local regulations may be required. Here, the greenhouse gases are roughly classified into six types of carbon dioxide, methane, dinitrogen monoxide, hydrofluorocarbon, perfluorocarbon, and sulfur hexafluoride, which are broadly defined internationally by the Kyoto Protocol. Each of these has a global warming potential, which is calculated based on this. Details are described in “Guidelines for Calculation of Greenhouse Gas Emissions from Businesses (Proposed Version 1.6)” issued by the Global Environment Bureau of the Ministry of the Environment.

  The carbon tax agent 930 is set for the purpose of reducing the amount of greenhouse gas emissions by converting the amount of greenhouse gas emissions into carbon dioxide based on the calculation method guidelines. For example, there is a proposal to specify 1400 yen per ton.

  Next, each apparatus used in a business office will be described with reference to FIGS. The elements of energy required for business activities vary depending on the business, but in general, as shown in FIG. 3, the major elements are energy for lighting, air conditioning, manufacturing, and transportation. Energy sources include electricity, gas, water, solar / heat, and oil. Moreover, natural gas, hydrogen gas, petroleum, nuclear power, coal, hydropower, solar power, wind power, etc. correspond to the fuel corresponding to these.

  On the other hand, from the technical point of view, the energy sources, fuels, and the like that can be used for each element are limited as shown by the lines indicating the relationship in FIG. That is, in the case of lighting, at present, energy sources are generally limited to electric power and sunlight. Of course, it is possible to turn on the lamp with oil depending on the preference, but it is difficult to consider in business activities where economic efficiency is a problem. In addition, as shown in FIG. 3, electric power is generated using various fuels and the like. However, in the case of private power generation for business use, the fuel used is limited.

  The lighting device 200 includes an illuminance measuring unit 210 that measures the illuminance of the office, in addition to an original lighting device such as a fluorescent lamp, an illumination power metering unit 220 that measures the power used by the lighting device, and an illumination that controls the illumination device. Control means 230 is provided, and is connected to the balance evaluation server 100 via the office communication line 640. What should be considered in the illumination is that sunlight can also be used as shown in FIG. 3, and it is desirable in terms of cost and environmental load suppression by using sunlight.

  The air conditioner 300 controls the temperature and humidity measuring means 310, the energy measuring means 320 that measures the energy of the air conditioner, and the air conditioner, in addition to the air conditioner and the heating equipment, etc. Air conditioning equipment control means 330 is provided. These means are connected to the balance evaluation server 100 via the office communication line 640.

  The manufacturing apparatus 400 includes an energy metering unit 410 that measures energy required for manufacturing, and a manufacturing process control unit 420 that controls the manufacturing apparatus, in addition to individual devices that differ depending on the type of business. These means are connected to the balance evaluation server 100 via the office communication line 640.

  The transportation device 500 is provided with an energy measuring means 510 for measuring energy used for the vehicle, in addition to a vehicle used for transportation or the like in a business office, a vehicle for transporting products, and the like. The energy measuring means 510 can be realized by measuring daily usage of gasoline, light oil or the like supplied at the office. But when purchasing from a commercially available gas station etc., it can also input from the terminal provided in the office separately, or the input means 160 of the balance evaluation server 100. FIG.

  Next, the usage of the balance evaluation system 1 according to the present invention will be described with reference to FIGS. FIG. 4 is a schematic diagram of a flowchart showing a flow of calculation and the like of the balance evaluation system 1. 5 and 6 are diagrams showing the prediction of the energy usage amount on the prediction day, and FIG. 7 is a diagram showing a balance evaluation between the energy cost and the environmental load suppression.

  Past performance data of energy consumption is stored in the storage means 150 in advance. Specifically, in the configuration described above, if lighting is described, the illuminance measured by the illuminance measuring means 210 and the illumination measured by the illumination power measuring means 220 in that case in relation to the day of the week and the weather The amount of power used is stored. Similarly, for air conditioning, temperature / humidity and the measured energy amount are stored in association with the day of the week and the weather. In addition, manufacturing and transportation are similarly stored.

  The operation after storing data necessary for the balance evaluation system 1 will be described below with reference to FIG.

  The prediction date on which the balance evaluation is to be predicted is input to the input means 160 of the balance evaluation server 100 (step S110). When the forecast date is entered, agent means (weather forecast agent 132, fuel cost agent 134, legal regulation agent 136) communicate information including forecast date weather forecast data, fuel cost forecast data, and legal regulatory conditions. Obtained via the line (step S120). Based on the obtained prediction information and the actual consumption data stored in the storage unit 150 in advance, the energy usage amount on the prediction day as shown in FIG. 5 or 6 is predicted (step S124). .

  The amount of energy used varies greatly depending on the weather and temperature. FIG. 5 is an example when the temperature is 25 ° C. and the sky is clear. Daily energy usage is only partly lit for security at night. At around 6 o'clock in the morning, transportation is performed and energy for transportation is used in order to arrange parts and the like in necessary places in preparation for manufacturing. When the start time comes, energy for manufacturing, air conditioning, and lighting begins to be used. During the lunch break, energy use for manufacturing will be very low, depending on the type of business. However, energy for air conditioning and lighting is used as long as people are in the office. In the afternoon, energy use increases again after the holidays. When manufacturing hours are over, there is almost no energy usage for manufacturing. On the other hand, when office workers are working overtime, energy will continue to be used for lighting and air conditioning. After that, when the office workers return home, after the end of their use, only the security lights are used and the day ends.

  FIG. 6 is an example of another day at the same office, where the temperature is as hot as 35 ° C. and the weather is cloudy. In this example, the energy use for air conditioning increases because it is hot. Also, the use of energy for lighting increases because it is cloudy.

  When the energy usage amount on the prediction day is predicted, the cost is calculated by the cost calculation means based on the prediction result and the information obtained by the fuel cost agent 134 (step S130). As shown in Fig. 1 and Fig. 3, the cost calculation is determined in advance by the facility of the establishment, so the product of the unit price obtained by the energy source and the fuel cost agent is obtained and the product is added. Desired.

  On the other hand, environmental load suppression is calculated by the environmental load suppression calculating means based on the predicted energy usage and information obtained by the legal regulation agent 136 (step S140). Calculation of environmental load suppression calculates the amount of greenhouse gas emissions for each type from the amount of energy used. The calculated discharge amount of each gas is converted into carbon dioxide gas. Conversion is performed according to the “Guidelines for calculating greenhouse gas emissions from business operators” issued by the Global Environment Bureau of the Ministry of the Environment.

  Thereafter, the cost of the predicted date and the environmental load suppression are displayed by the display means 140 (step S150). FIG. 7 shows an example of the display result. In FIG. 7, the horizontal axis represents the amount of energy used, and the vertical axis represents the amount of greenhouse gas emissions converted to carbon dioxide. Conversion to carbon dioxide is based on the global warming potential introduced in the “Guidelines for calculating greenhouse gas emissions from businesses” issued by the Global Environment Bureau of the Ministry of the Environment.

  Normally, as energy consumption increases, the equivalent greenhouse gas emissions also increase. As the amount of energy used described in FIG. 5 or 6 increases, the amount of greenhouse gas emissions also increases. When the amount of energy used is small, the equipment that the operator thinks is most appropriate is used. When the amount of energy used increases and the capacity of the facility you think is most appropriate is full (Q1 point), because it is supplied from another facility or supplier, the amount of greenhouse gas emissions is also required for facility operation. Cost also increases non-linearly.

  On the other hand, there is currently no regulation value for greenhouse gas emissions by business. However, because the treaty promises reductions under the Kyoto Protocol as a Japanese country, large operators may be required to self-regulate. In that case, it is required to set a standard limit and operate it independently. For example, when the reference limit is set as shown in FIG. 7, the energy use limit must be suppressed by Q2.

  Moreover, the display by the display means 140 can also be displayed as shown in FIG. FIG. 8 shows the relationship between the energy cost and the carbon tax when the carbon tax is introduced at ¥ 2400 / ton. By displaying in this way, it is possible to grasp the situation including environmental load suppression. Further, when the carbon tax is changed, the information on the changed data is obtained by the legal regulation agent 136, and the carbon tax based on the content is displayed together.

  As described above, according to the present invention, weather forecast data, fuel cost forecast data, and information on the date entered by the user regarding legal constraint conditions can be obtained via a communication line, so that necessary energy, cost, and environmental load suppression are reduced. Can be calculated appropriately. The operator can choose to minimize the cost within the scope of legal restrictions if the cost is important in view of the calculation result. In addition, when it is determined that environmental load suppression is important even if some costs are incurred, it is possible to select to minimize environmental load suppression.

[Second Embodiment]
FIG. 9 is a schematic diagram of a flowchart showing a flow of calculation or the like which is another embodiment of the balance evaluation system 1. The second embodiment is characterized in that balance point input (step S260), sharing calculation (step S270), and control of each device (step S280) are added to the first embodiment. Since the other parts are the same as those in the first embodiment, the added part will be described and the description of the same part will be omitted.

  After considering the display according to the first embodiment, a balance point to be used for operation is set. For example, in the example shown in FIG. 7, it is set to the point Q2 that is the reference value of the greenhouse gas. Then, the balance point is input by the balance point input means (step S260). The sharing calculation means calculates the sharing of each device of the energy generating device and the using device so as to operate at the input balance point (step S270). The content of the calculated assignment is transmitted to the control means (lighting control means 230, air conditioning equipment control means 330, manufacturing process control means 420) of each device via the office communication unit 120 to control the operation of each device ( Step S280).

  In this way, since the operation at the balance point is ensured, the best operation is achieved in view of the generation and cost of greenhouse gases. In addition, after each division is calculated, this can be displayed, and it can also be operated by instructing through other communication lines instead of direct control.

[Third embodiment]
Although the above example mainly explained the balance evaluation system, it is similarly realized by installing a balance evaluation program having the means described in the balance evaluation system 1 in a computer and causing the computer to function as the means. Can do.

  As a result, the same effect as described in the first embodiment can be obtained.

[Fourth embodiment]
FIG. 10 is a schematic diagram of a flowchart showing a flow of calculation or the like which is an embodiment of the long-term balance evaluation program of the present invention. FIG. 11 is a graph in the case of using an in-house power generation facility as a result of a trial calculation by a long-term balance evaluation program. FIG. 12 is a graph in the case of combined use with a natural energy power generation facility as a result of a trial calculation by a long-term balance evaluation program.

  Even if the energy supply equipment is small, some capital investment is required. On the other hand, environmentally superior power generation using natural energy such as wind power generation and solar power generation has been attracting attention. In addition, the generation of electricity with a fuel cell using hydrogen is about to become practical. In addition, it is desirable to use sunlight appropriately for lighting, heating, and the like.

  However, both require considerable capital investment and are currently more expensive than the power generation costs of electric power companies. However, since it emits almost no greenhouse gases in terms of the environment, if the carbon tax, etc. rises and the crude oil etc. soars, the adoption value is recognized. From this point of view, it is desirable to consider energy cost and environmental load control that also considers environmental accounting. The fourth embodiment provides a program for solving a problem from such a viewpoint.

  In this embodiment, since there are four seasons in Japan, a prediction is made on a monthly basis, and the cost and environmental load of the predicted month are calculated. After that, the calculation for 12 months is performed. By calculating the maximum use value, the monthly average use value, etc. of the energy after the calculation, it is possible to simulate whether to make the optimum equipment or system.

  Instead of inputting the predicted date in the first embodiment, a predicted month is input (step S310). The entered forecast month agent means (weather forecast agent 132, fuel cost agent 134, legal regulation agent 136) the forecast month's weather forecast data, fuel cost forecast data, and the highest month value including legal regulatory conditions; Information such as the average value is obtained via the communication line (step S320). Based on the obtained prediction information and the actual data of energy consumption stored in the storage unit 150 in advance, the prediction of the maximum energy value and the average energy usage of the prediction month corresponding to FIG. 5 or FIG. (Step S324).

  When the energy usage amount in the prediction month is predicted, the cost is calculated by the cost calculation means based on the prediction result and the information obtained by the fuel cost agent 134 (step S330). As shown in Fig. 1 and Fig. 3, the cost calculation is determined in advance by the facility of the establishment, so the product of the unit price obtained by the energy source and the fuel cost agent is obtained and the product is added. Desired. Also consider by adding the devices to be studied. In that case, the cost of the equipment to be examined is calculated according to the guidelines of environmental accounting (issued by the Ministry of the Environment, see Environmental Guidelines).

  On the other hand, environmental load suppression is calculated by the environmental load suppression calculation means based on the predicted energy usage and information obtained by the legal regulation agent 136 (step S340). Calculation of environmental load suppression calculates the amount of greenhouse gas emissions for each type from the amount of energy used. The calculated discharge amount of each gas is converted into carbon dioxide gas. Conversion is performed according to the “Guidelines for calculating greenhouse gas emissions from business operators” issued by the Global Environment Bureau of the Ministry of the Environment.

  Thereafter, the cost of the predicted date and the environmental load suppression are displayed by the display means 140 (step S350). FIG. 11 shows an example of a display result when a business operator owns a private power generation facility. It is a trial calculation result when purchasing power from an electric power company or the like (displayed as the amount of power purchased) and when generating privately (displayed as the amount of power generation). In FIG. 11A, the horizontal axis represents the amount of energy used, and the amount of power generation and the amount of power purchased are displayed in reverse. The vertical axis represents greenhouse gas emissions converted to carbon dioxide. Conversion to carbon dioxide is based on the global warming potential introduced in the “Guidelines for calculating greenhouse gas emissions from businesses” issued by the Global Environment Bureau of the Ministry of the Environment.

  Further, FIG. 11B shows a display in which the cost when the carbon tax is introduced is added to the energy cost. In the case where the carbon tax is not introduced, it can be seen that what was balanced in terms of Q3 in FIG. 11B balances in Q4 by introducing the carbon tax.

  FIG. 12 shows a display example of a trial calculation result when the natural energy power generation facility is used together. Natural energy power generation facilities have very low carbon dioxide emissions. However, capital investment is newly required and taking this into account, it is expensive compared to the unit price currently being generated by the power company. However, when the carbon tax is introduced, the balance point shifts from Q4 to Q5 in FIG.

  The display result is checked to determine whether the calculation is necessary again (step S360). If necessary, the apparatus is further changed and corrected (step S370), and the calculation is performed again.

  As mentioned above, although demonstrated using embodiment of this invention, the technical scope of this invention is not limited to the range as described in the said embodiment. Various modifications or improvements can be added to the above embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention. For example, a dedicated communication line may be used as the public communication line.
