Description

Technical Field

[0001] The present invention relates to an energy-saving document creation service system for buildings, particularly an energy-saving document creation service system for buildings suitable for shortening the creation time of energy-saving documents for buildings in the initial design stage.

Background Art

[0002] The government is implementing measures for the global warming countermeasure plan, setting a target of reducing the greenhouse gas emissions to be reduced by 40% by 2030 for the "business and other sectors", and promoting energy conservation of buildings by dividing the uses of buildings into two categories: housing and non-housing (office buildings, schools, department stores, hotels, service industries). In particular, as measures for energy conservation of non-housing buildings, promotion of compliance with energy conservation standards for new buildings, energy conservation (renovation) of existing buildings, promotion of net-zero energy buildings (hereinafter referred to as ZEB), promotion of popularization of low-carbon certified buildings, etc., and improvement and promotion of the evaluation and display system for energy conservation and environmental performance are cited. The promotion of compliance with energy conservation standards for new buildings is attempted to be achieved by complying with the laws stipulated in the "Building Energy Conservation Law". In addition, since applicants such as businesses need to conform to the energy conservation standards for housing and non-housing, the construction cost also increases, so subsidies for energy conservation standard compliance measures are provided to businesses.

[0003] The application criteria for energy conservation are set according to the construction area of the building, and the building cannot be constructed unless the application criteria are cleared. At the time of building design and when the building construction is completed, it is necessary to undergo a conformity inspection. However, since there are a large number of application documents, the application and review take time and may not be completed by the delivery date.

[0004] Therefore, in order to ensure the fairness of the application and review of energy conservation standards and reduce the burden, the Ministry of Land, Infrastructure, Transport and Tourism has published the "Energy Consumption Performance Calculation Program (Non-Housing Version)". An applicant can calculate the energy conservation rate of a building by inputting the necessary information into a predetermined input sheet and executing the energy consumption performance calculation program.

[0005] However, there is a problem in that the program has many input fields, making it difficult to use when the architectural design has not yet been finalized.

[0006] Therefore, there is a need for a service that provides reports containing insulation specification diagrams and equipment specification lists once certain insulation and equipment specifications have been decided during the initial design phase.

[0007] The system proposed in Patent Document 1 discloses an information processing system that allows users to more effectively compare the energy consumption of multiple buildings.

[0008] Patent Document 2 discloses a terminal device that incorporates an application program for generating intermediate data for an API server that calculates the energy-saving performance of buildings. [Prior art documents] [Patent Documents]

[0010] The aforementioned Patent Document 1 displays a comparative view of multiple buildings during the calculation execution of an energy consumption performance calculation program, but it did not take into consideration a certain degree of insulation specifications or equipment specifications listed in the initial design stage when creating the report.

[0011] The aforementioned Patent Document 2 reduces system development costs by utilizing an API server for calculating the energy-saving performance of buildings, but it did not take into account the insulation specifications and equipment specifications listed in the initial stages of design when creating reports.

[0014] The building energy-saving data creation service system according to the second invention further includes an additional update unit that receives additional update information for the energy-saving data from the user terminal and updates the energy-saving data, and a calculation execution unit that calculates energy consumption performance using an energy consumption performance calculation program based on the additional update energy-saving data, and is characterized in that it makes an application based on the energy-saving data calculated by the calculation execution unit.

[0015] The energy-saving data creation service system for buildings according to the third invention is further characterized in that, in the first or second invention, the energy consumption performance calculation program is a web program.

[0016] The energy-saving document creation service system for buildings according to the fourth invention further includes a document creation unit for creating other application documents in the third invention.

Mode for Carrying Out the Invention

[0019] Hereinafter, embodiments exemplified by applying the present invention will be described with reference to the drawings.

[0020] <Embodiment 1> As shown in Figure 1, the server 7 equipped with the energy-saving document creation service system 5 of this embodiment has multiple user terminals 1, 2, and 3 used by users requesting the creation of energy-saving documents for buildings, and a server device connected to the user terminals 1, 2, and 3 via a communication network 4 to receive requests for the creation of energy-saving documents for buildings. The server 7 implementing the energy-saving document creation service system 5 creates energy-saving documents in the early stages of design by utilizing a database of past application history, thereby shortening the time required to create energy-saving documents.

[0021] The Energy Saving Document Creation Service System 5 periodically acquires data from past application documents in accordance with the provisions of the Building Energy Conservation Act and stores it in a database. The Energy Saving Document Creation Service System 5 will be explained in detail below using Figures 2 and 3. As shown in Figure 3, the Energy Saving Document Creation Menu is displayed on the server's display unit. The Energy Saving Document Creation Menu consists of input for basic design information, insulation specification information, air conditioning equipment information, ventilation equipment information, lighting equipment information, hot water supply equipment information, elevator presence / absence information, and solar power generation equipment information. Server users can input various information by selecting each input menu. Other necessary input items may be added.

[0022] As shown in Figure 2, the energy-saving document creation service system 5 includes a design basic information input unit 51, an insulation specification information input unit 52, an equipment information input unit 53, an energy-saving document creation unit 54, and an energy-saving document report output unit 55.

[0023] The design basic information input unit 51 inputs design basic information, including at least the user's initial design information such as the building's use, area, number of floors, and target ZEB rank.

[0024] The design basic information input screen, as shown in Figure 4, consists of fields such as property name, purpose, area, number of floors, and rank. In the example in Figure 4, the property name is "New Construction of XX Construction Company Building," the purpose is "Office," and the area is "600-700" m². 2This example shows the floor number entered as "2F above ground, 0F below ground" and the rank as "Nearly ZEB (BEI=0.25)".

[0025] The thermal insulation specification information input unit 52 inputs thermal insulation specification information, including at least information on the roof, walls, outdoor floor, ground floor, and fixtures, based on the basic design information input unit 51.

[0026] The insulation specification input screen, as shown in Figure 5, consists of the roof, walls, outdoor floor, concrete floor, joinery, and insulation type specification. The example in Figure 5 shows an example where the roof is specified as "50-100" mm, the walls as "50-100" mm, the outdoor floor as "50-100" mm, the concrete floor as "30" mm, the joinery as "Low-E composite glass", and the insulation type specification is "None (selected)".

[0027] The equipment information input unit 53 inputs equipment information for at least one of the following: air conditioning, ventilation, lighting, hot water supply, elevators, and solar power generation, or a combination thereof.

[0028] The air conditioning equipment information input screen, as shown in Figure 6(a), consists of the air conditioner, control method, and outdoor unit air conditioning capacity. In the example in Figure 6(a), the air conditioner is set to "High-efficiency multi-split air conditioner for buildings," the control method to "Number of units control," and the outdoor unit air conditioning capacity to "1m³." 2 The example shows input of "approximately 0.2kW per unit". Unit control is shown in Figure 17(a). Unit control is one of the control methods for air conditioners, and applies to systems where multiple outdoor units form a set. When there is excess capacity in the air conditioning system, the outdoor units are automatically shut down to save energy.

[0029] As shown in Figure 6(b), the ventilation equipment information input screen offers three power saving levels: "High," "Medium," and "Low." Figure 6(b) shows an example where "Low" power consumption is selected.

[0030] The lighting equipment information input screen, as shown in Figure 6(c), consists of lighting equipment and energy-saving functions. The example in Figure 6(c) shows an instance where "high-efficiency lighting (LED)" is entered for the lighting equipment and "motion sensor, brightness control, and time schedule" are entered for the energy-saving functions. Energy-saving control through zoning control of lighting equipment is shown in Figure 17(b). Zoning control of lighting equipment reduces power consumption in non-habitable areas (corridors, entrances, parking lots, etc.) by dimming or turning on lights according to the time of day. This zoning control of lighting equipment should be adopted as appropriate.

[0031] Figure 17(c) shows how to create a building structure that utilizes daylight and how to control energy saving through dimming of lighting equipment. Building structures that utilize daylight can employ light shelves, atriums, skylights, etc., and the power consumption of lighting can be reduced by using automatic switching control based on brightness sensing or by using a combination of daylight utilization control with brightness sensors.

[0032] The hot water supply equipment information input screen, as shown in Figure 6(d), consists of NG equipment, recommended equipment, recommended equipment, and toilet energy saving. In the example in Figure 6(d), "electric water heater" is entered for NG equipment, "heat pump water heater" for recommended equipment, "gas water heater" for recommended equipment, and "Yes (selected)" for toilet energy saving.

[0033] The elevator presence / absence information input screen consists of selecting "Yes" or "No" for the elevator, as shown in Figure 6(e). Figure 6(e) shows an example where "No" is selected for the elevator.

[0034] As shown in Figure 7, the solar power generation equipment information input screen consists of the target ZEB rank, array system capacity, and application for the new ZEB support program. In the example in Figure 7, "Nearly ZEB" is entered for the target ZEB rank, "20" kW for the array system capacity, and "Yes (selected)" for the application for the new ZEB support program.

[0035] The above input information is analyzed by AI, and example data, as shown in Figure 8, is inserted into the energy-saving document creation. For example, if "None" is selected for the insulation type in the insulation specification information input, "No insulation type has been specified." is inserted. The same insertion is performed for other equipment information inputs. For example, in the solar power generation equipment information input, "We believe that the array system capacity of approximately 20kW is sufficient to meet Nearly ZEB standards, but to increase the chances of being selected for the LCCO2 reduction type leading new construction ZEB support program, we recommend increasing it to approximately 30kW." is inserted. In addition, as shown in Figure 9, remarks data and note data can also be inserted.

[0036] The energy conservation document creation unit 54 creates energy conservation documents showing compliance with energy conservation standards based on insulation specification information and equipment information.

[0037] The energy-saving data report output unit 55 outputs the energy-saving data created in the energy-saving data creation unit 54 as a report to the user terminal 1.

[0038] Figure 10 shows the basic processing flowchart of the energy-saving data creation service system described above.

[0039] As shown in Figure 10, the energy-saving document creation service system includes a design basic information input step 101, an insulation specification information input step 102, an equipment information input step 103, an energy-saving document creation step 104, and an energy-saving document report output step 105. The order of input in these input steps 101 to 103 may be changed. Details of the above steps 101 to 105 are as described above and will not be explained here.

[0040] Figure 11 is a detailed flowchart of the equipment information input step 103 in Figure 10. As shown in Figure 11, the equipment information input step 103 includes an air conditioning equipment information input step 201, a ventilation equipment information input step 202, a lighting equipment information input step 203, a hot water supply equipment information input step 204, an elevator presence / absence information input step 205, and a solar power generation equipment information input step 206. Details of steps 201 to 206 are as described above, so an explanation is omitted here.

[0041] The server further includes an additional update unit (not shown) that receives additional update information for energy-saving data from user terminal 1 and updates the energy-saving data, and a calculation execution unit (not shown) that performs calculations using an energy consumption performance calculation program based on the updated energy-saving data. Online applications may be submitted during the review period based on the energy-saving data calculated by the calculation execution unit (not shown). The energy consumption performance calculation program may be a web program. For example, various input data may be sent from server 7 to the Ministry of Land, Infrastructure, Transport and Tourism website 6 to calculate the energy consumption performance, which is the main calculation for buildings. Furthermore, it may also have an application document creation unit (not shown) that creates other application documents.

[0042] Figures 12 to 16 are excerpts from the application guidelines for the Leading ZEB Support Program for LCCO2 Reduction. Figure 12 shows examples of eligible projects for the Leading New Construction ZEB Support Program for LCCO2 Reduction. Figure 13 shows the definition of ZEB in Figure 12. Figure 14 shows examples of eligible uses in Figure 12. Figure 15 shows the ZEB rank and subsidy rate in Figure 12. Figure 16 shows the additional amount due to CO2 reduction in the ZEB rank in Figure 12.

[0043] As such, there are various subsidy programs to support new ZEB construction, so it is important to create energy-saving documents that take the ZEB rank into consideration from the initial design stage. According to this embodiment, the time required to create energy-saving documents can be shortened, and the ZEB compliance rank under the Energy Conservation Act can be determined without performing the main calculations of the energy consumption performance calculation program, thus reducing the amount of work required in the initial design stage and decreasing the frequency of design changes.

[0044] Figure 18 shows an example of a system configuration in which the functions of the energy-saving document creation service system 5 shown in Figure 2 are implemented on server 7.

[0045] As shown in Figure 18, Server 7 includes a communication control unit 71, a reception unit 72, a program processing unit 73, an input unit 74, a display unit 75, a past application history database 76, an insulation specification database 77, an equipment information database 78, an example database 79, an energy-saving document creation unit 80, and an energy-saving document report output unit 81. The past application history database 76 is a database with a data structure as shown in Figure 19, and it contains bibliographic information of various application data and is associated with detailed data of the property name. Therefore, past application history data can be used when creating energy-saving documents, which reduces the document creation time.

[0046] As shown in Figure 20, user terminal 1 includes a control unit 11, a communication unit 12, a display unit 13, a storage unit 14, and an input unit 15. The configurations of user terminals 2 and 3 are the same as those in Figure 20. Specifically, the configurations are similar to those of general hardware such as personal computers, tablet terminals, and smartphones, so a detailed explanation is omitted. User terminal 1 can use the energy-saving document creation service by accessing the internet from the browser screen of a personal computer or smartphone.

[0047] Ultimately, in the energy-saving document creation service, the energy-saving document report is provided in the format shown in Figures 21 and 22.

[0048] In the embodiments described above, the creation of energy-saving data shown in Figure 21 was explained, but the same method can also be applied to the creation of energy-saving data shown in Figure 22. [Explanation of Symbols]
