Description

Building energy modeling automation system and method using the same

[0001] The present invention relates to an automated building energy modeling system and a method using the same, and more particularly, to an automated building energy modeling system and a method using the same, which diagnoses energy consumed in a building, thereby minimizing the emission of unnecessary energy that causes environmental problems and further reducing the energy bill of the building.

[0002] A Building Energy Management System (BEMS) is a system that efficiently manages the energy used within a building. Specifically, it collects and analyzes various information from energy management facilities within the building to improve energy efficiency. Using the BEMS can result in energy savings of 5-15% on average. Therefore, with the recent strengthening of various laws and standards regarding building energy consumption and the growing need for energy conservation, there is a growing trend toward actively adopting BEMS. The BEMS establishes a building energy model based on the characteristics of the building and controls and manages the operation of the building's energy facilities based on this model.

[0003] However, existing building energy models used to implement building energy management systems are initially established during construction and remain in place throughout the building's lifespan. Consequently, changes in energy performance due to aging or replacement of building and facility systems are not reflected. Furthermore, if managers rely on experience to control operations, significant energy waste can occur.

[0004] Furthermore, energy consumption in buildings has recently emerged as a major cause of environmental problems. Carbon emissions increase as electricity, gas, and other consumption in buildings increase depending on the weather, and reducing energy consumption in buildings is being proposed as a prerequisite for achieving carbon neutrality.

[0006] The purpose of the present invention is to provide a building energy modeling automation system and a method using the same for remodeling a building and reducing building energy by diagnosing the energy consumption information of the building and minimizing unnecessary energy consumption.

[0007] In particular, the purpose is to provide an automated building energy modeling system and a method using the same that can diagnose whether unnecessary energy is consumed based on the structural characteristics of the building and the environmental characteristics of the area where the building is installed.

[0008] In addition, the present invention aims to provide a building energy modeling automation system and a method using the same, which can propose a program for reducing energy consumption information when the energy consumption occurring during building use is greater than the average building energy consumption information when comparing the energy consumption occurring during building use with the set average building energy consumption information.

[0009] The method for estimating energy consumption standard information of a building by a server of the present invention includes the steps of obtaining basic information including footprint information, use information, and height information of a target building from a building database, generating external information of the target building based on the basic information, generating window information including information on the area of ​​a window of the target building based on the basic information, generating energy consumption standard information of the target building based on the basic information and the window information, and generating estimated image information of the target building by reflecting the window information in the external information.

Specifically, the time-point information includes at least one of information regarding the groundbreaking, commencement, construction, completion, and completion of the target building, and at least one of the exterior information and the window information may be determined based on the time-point information.

[0011] In an embodiment, the process of generating the exterior information may include identifying the exterior type of the target building from an exterior database including information on a plurality of standard exterior types distinguished according to the viewpoint information of the building, and generating the exterior information based on the footprint information, the height information, and the exterior type.

[0013] In an embodiment, the process of generating the window information may include a process of confirming building orientation information of the target building based on the footprint information and the exterior information, confirming a reference plane of the target building based on the building orientation information, and generating the window information such that at least a portion of the windows of the target building are located on the reference plane.

[0014] In an embodiment, the windows of the target building include a main window and a sub-window, and in the process of generating the window information so as to be positioned on the reference plane, the server can generate the window information so that the main window is positioned on the reference plane.

[0028]

[0029] Hereinafter, the present invention will be described with reference to the attached drawings.

[0030] FIG. 1 is a drawing illustrating an environment in which a building energy modeling automation system according to an embodiment of the present invention is implemented.

[0031] An environment (10) in which a building energy modeling automation system according to an embodiment of the present invention is implemented is connected to a server (100) that estimates building energy consumption standard information, and a terminal (200) that displays building energy consumption standard information estimated through the server (100).

[0032] In an embodiment, the server (100) may obtain basic information of a target building (50) for which energy consumption standard information is to be estimated from a building database, and may generate external information of the target building based on the obtained basic information of the target building (50). The generated external information of the target building (50) may be data capable of generating an estimated image of the target building (50). In addition, window information regarding window area information of the target building may be generated based on the basic information of the target building (50). The generated window information of the target building (50) may be data capable of generating energy consumption standard information of the target building.

[0033] That is, the server (100) can display energy consumption information consumed through information about the windows of the target building (50) on the image of the target building (50). By displaying the energy consumption information of the target building (50) on the image in this way, the energy consumption information of the target building (50) can be visually confirmed. Specifically, buildings with high energy waste and buildings with high energy saving effects can be displayed for each building, thereby enabling the estimation of energy consumption information for each building.

[0034] Let's take a closer look at a system that estimates a building's energy consumption information with reference to the drawing below.

[0035] FIG. 2 is a diagram illustrating a configuration of a building energy modeling automation system according to an embodiment of the present invention, and FIGS. 3 and 4 are diagrams illustrating examples of estimating energy information of a building through a building energy modeling automation system according to an embodiment of the present invention.

[0036] Before describing the drawings, for the convenience of explanation, the building energy modeling automation system will be described with an example implemented as a server. The server (100) may be installed in a target building (50) and configured to estimate energy consumption reference information of the target building (50), or may be implemented with one of the urban maintenance servers capable of estimating energy consumption reference information of a plurality of buildings including the target building (50). In the following embodiment, the server (100) is described with an example of being one of the urban maintenance servers, but the present invention is not limited by the conditions of the server (100) being implemented.

[0037] Furthermore, the building energy modeling system of the embodiment generates a building energy usage model capable of simulating the energy usage of a target building, and uses the generated simulation results to estimate the target building's energy consumption. Subsequently, based on the estimated target building's energy consumption, a building remodeling (repair, improvement) can be simulated to reduce the target building's energy consumption. This allows for an estimate of the target building's energy savings, and the estimated results can be used to guide and implement actual remodeling of the target building.

[0038] Specifically, referring to the drawing, the server (100) may be configured to include a communication unit (120), a data collection unit (140), an information generation unit (160), a memory (180), and a processor (190).

[0039] The communication unit (120) is configured to transmit a unique number assigned to the target building (50) or the building address of the target building (50) to a building database, and to receive basic information of the target building (50) from a building database containing building register information or an organization such as KEPCO.

[0040] The data collection unit (140) is configured to collect basic building information. Specifically, it receives basic building information (50) via a building database connected to the communication unit (120). Specifically, basic building information may include a footprint (building floor), building use information, building height information, and the like. This basic building information can be received from building information already stored in organizations such as the Ministry of Land, Infrastructure and Transport and the Korea Appraisal Board.

[0041] In addition, the data collection unit (140) can receive power consumption information of the target building (50). The power consumption information of the target building (50) can be received through an organization such as Korea Electric Power Corporation, and in addition to the power consumption information of the target building (50), information on energy consumption reduction conditions such as energy information subsidies can also be collected.

[0042] Meanwhile, the basic information may further include construction-related time information of the target building (50). Here, the time information may include at least one of groundbreaking, commencement, construction, completion, and completion information of the target building (50). That is, the type of building construction, external characteristics, etc. may differ depending on the construction time of the target building (50). Based on these characteristics, the external appearance of the target building (50) or the shape of the windows may be determined at the time of construction of the target building (50). In addition, the older the building is constructed, the lower the energy consumption efficiency of the building generally is. Based on these characteristics, the external appearance information and window information regarding the building's external appearance and window shape may be determined depending on the construction time of the target building (50), thereby estimating the energy consumption reference information of the target building (50).

[0043] Meanwhile, when the server (100) generates the exterior information of the target building (50), it can check the exterior type of the target building (50) from an exterior database that includes information on a plurality of standard exterior types distinguished according to the building construction time information.

[0044] As described, the exterior appearance of a building may include different trends depending on the time the building was built, the architect, etc. The exterior appearance database that classifies the building exterior information by year, architect, etc. and the server (100) can be connected to each other, and the exterior appearance information of the target building (50) generated through the basic information of the target building (50) can be used to determine at which time and by which architect it was built in the exterior appearance database. Based on the determined information and the basic information of the target building (50), the actual exterior appearance of the target building (50) is estimated.

[0045] Meanwhile, depending on the time of construction of the building, the type of window installed in the building, the shape of the window, the insulation standards for the window, etc. may vary. These characteristics can be divided into multiple standard window information items according to time of construction, architect, etc., and the window type of the target building (50) can be estimated based on the standard window information.

[0046] Based on the exterior information and window information of the target building (50) measured in preparation for the time of construction of the building, energy consumption standard information of the target building (50) can be generated based on the exterior information of the target building (50), the type, shape, insulation, etc. of the windows installed in the target building (50), and the window information.

[0047] Meanwhile, when generating window information of a target building (50), orientation information of the target building (50) can be confirmed based on the footprint information of the target building (50) and the exterior information of the target building (50). The orientation information of the building can be said to be the location where the building is placed, and can mean, for example, facing south, facing north, etc.

[0048] Once the orientation information of the target building (50) is confirmed, the reference plane of the target building (50) can be confirmed, and window information can be generated so that some of the windows of the target building (50) are located on the reference plane. Generally, when confirming the orientation of a building, in the case of an apartment, the direction of the building can be estimated based on the direction in which the living room window is formed, and in the case of a general building, the direction of the building can be estimated based on the plane in which the main window is formed. After confirming the orientation information of the target building (50) based on these characteristics, the reference plane can be determined according to the orientation of the target building (50). Thereafter, window information of the target building (50) can be generated so that the main window of the target building (50) is located on the determined reference plane.

[0049] When basic information of a building is acquired, external information of the target building (50) can be generated based on the basic information acquired through the information generation unit (160). External information of the target building (50) can refer to the number of floors, height, shape, etc. of the building.

[0050] Specifically, the information generation unit (160) can generate design information of the target building (50). The design information of the target building (50) may be any one of the number of floors of the target building, average floor height information according to use, length information of the target building (50) according to building height, etc. Based on the generated design information of the target building (50), energy consumption standard information according to height, floor height, etc. can be estimated.

[0051] Additionally, the information generation unit (160) can generate window information including information on the window area of ​​the target building (50) based on basic information. For each building, the number of windows to be installed, the minimum width of the installed windows, etc. can be preset according to the building use, building area, etc. Window information of the target building (50) can be generated based on these criteria and the basic information of the target building (50).

[0052] In an embodiment, the information generation unit (160) can generate energy consumption standard information of the target building (50) based on basic information and window information of the target building (50). The energy consumption standard information of the target building (50) can be said to be information estimating the amount of energy consumed in the building, and by comparing the generated energy consumption information with energy information to be consumed in the target building (50) that has already been stored, the amount of unnecessary energy consumption of the target building (50), building energy efficiency, etc. can be determined.

[0053] In an embodiment, the information generation unit (160) may generate estimated image information of the target building by reflecting window information into the exterior information of the target building (50). Based on the generated estimated image information of the target building (50) and the energy consumption information of the target building (50), the energy consumption status of the target building may be displayed.

[0054] Referring to the drawing again, when acquiring basic information of the target building (50), it is also possible to estimate the energy consumption standard information of the target building (50) by acquiring additional information on at least one of information on a road view that captured an image of the target building (50), an evaluation of the target building (50), and information on the heating and cooling method and load of the target building (50).

[0055] Road view information refers to video and image information of the target building (50) and its surroundings, obtained through photos of the building on social media. This road view information includes the exterior appearance of the target building (50), window installation locations, and the reference plane of the target building (50).

[0056] Additionally, energy consumption baseline information can be estimated by assessing the evaluation of the target building (50) on social media. A building's evaluation can refer to the level of energy consumption perceived by building users. For example, if a building's evaluation indicates that its energy consumption costs are higher than those of other buildings, the target building (50) can be assessed as having high energy consumption and thus being wasteful.

[0057] Additionally, energy consumption baseline information can be estimated based on natural language input by building users on social media. In other words, natural language words describing the building's heating and cooling system or its structure (e.g., "apartment structure"—corridor, staircase, etc.)—can be collected, and the building's energy consumption baseline information can be estimated based on this collected natural language.

[0058] Similarly, energy consumption standard information can be estimated based on the power consumption or heating / cooling method of the target building (50). For example, in the case of an apartment, the power consumption or heating / cooling method may differ between a corridor-type apartment where multiple units are located side by side and a staircase-type apartment where two or so units are placed facing each other.

[0059] If the actual power consumed by the target building (50) is higher than the preset power consumption and load information for the target building (50), the energy consumption of the target building (50) is estimated to be high. In addition, if the energy consumed by the target building (50) is higher than the energy that should be consumed based on the preset heating and cooling room, the energy consumption of the target building (50) may also be estimated to be high.

[0060] Meanwhile, when estimating the energy consumption standard information of the target building (50), it is also possible to estimate the energy consumption standard information according to seasonal changes. Since the energy consumption of the target building (50) may be lower in spring and fall than in summer and winter, it is possible to estimate which season has the highest energy consumption by comparing the energy consumption levels by season.

[0061] In this way, the energy usage pattern and usage analysis data of the target building (50) can be derived based on the basic information, architectural information, window information, etc. of the target building (50) collected through the information collection unit ().

[0062] The derived energy usage pattern and usage analysis data of the target building (50) can be used as energy consumption analysis data between the target building (50) and surrounding buildings, as shown in Fig. 4. In addition, the derived energy usage pattern and usage analysis data of the target building (50) can be used to estimate the cause of energy waste when the target building (50) has high energy consumption.

[0063] In general, when there are many windows or when the windows are not double-glazed, energy waste can be high. Therefore, unnecessary energy consumption of the target building (50) can be minimized by supplementing the window condition, type, etc. using window information of the target building (50).

[0064] Meanwhile, the derived energy usage pattern and usage analysis data of the target building (50) can be displayed through the terminal (200). That is, the energy usage pattern and usage analysis of the current target building (50) by season, weather, and comparison with surrounding buildings can be visualized to provide guidance on the level of energy consumption of the target building (50).

[0065] The memory (180) can store operation codes for the server (100) to operate and operation data for estimating energy consumption standard information of the target building (50).

[0066] The processor (190) can control the overall operation of the server (100). The processor (190) processes signals, data, information, etc. input or output through the components discussed above, or drives an application program stored in the memory (120) to provide or process appropriate information or functions for estimating energy consumption standard information of the target building (50).

[0067]

[0068] FIG. 5 is a diagram illustrating a process for estimating energy consumption reference information according to an embodiment of the present invention.

[0069]

[0070] *Referring to the drawing, the process for estimating building energy consumption standard information of the present invention can first collect basic building information via the server (100) (S120). Basic building information may refer to information such as the building footprint (the building's floor), building use information, and building height information. This basic building information can be received from building information already stored by organizations such as the Ministry of Land, Infrastructure and Transport and the Korea Appraisal Board.

[0071] In addition, power consumption information of the target building (50) can be received. Power consumption information of the target building (50) can be received through an organization such as Korea Electric Power Corporation, and in addition to power consumption information of the target building (50), information on energy consumption reduction conditions such as energy information subsidies can also be collected.

[0072] Meanwhile, when generating basic information, the basic information can be generated by including construction-related time information. Here, the time information can include at least one of the following information regarding the groundbreaking, commencement, construction, completion, and completion of the target building (50). That is, the type of building construction, external characteristics, etc., may vary depending on the time of construction of the target building (50). Based on these characteristics, the external appearance of the target building (50) and the shape of its windows can be determined at the time of construction of the target building (50).

[0073] Thereafter, the exterior information and window information of the target building (50) can be generated (S130, S140). When generating the exterior information of the target building (50), the exterior type of the target building (50) can be identified from an exterior database that includes information on multiple standard exterior types distinguished according to the building's construction time information.

[0074] Specifically, the exterior appearance of a building may include different trends depending on the time the building was built, the architect, etc. The exterior appearance database that classifies the building exterior information by year, architect, etc. and the server (100) can be connected to each other, and the exterior appearance information of the target building (50) generated through the basic information of the target building (50) can be used to determine at which time and by which architect it was built in the exterior appearance database.

[0075] In addition, since the type of window installed in the building, the shape of the window, the insulation standard of the window, etc. may be different depending on the time information of the building when it was constructed, it is possible to divide it into multiple standard window information according to the time, architect, etc., and estimate the window type of the target building (50) based on the standard window information.

[0076] In particular, based on the exterior information and window information of the target building (50) measured in preparation for the time of construction of the building, energy consumption standard information of the target building (50) can be generated based on the window information on the exterior of the target building (50), the type, shape, insulation, etc. of the windows installed in the target building (50).

[0077] Thereafter, energy consumption standard information of the target building (50) can be generated (S150). That is, the energy consumption rate of the target building (50) can be estimated based on information such as the building's construction date and window shape, and problems of the target building (50) can be estimated. If the interior of the target building (50) is improved based on the estimated problems of the target building (50), the energy savings of the target building (50) can also be calculated.

[0078] In an embodiment, when window information is generated in the external information of the target building (50), estimated image information of the target building (50) can be generated. Based on the generated estimated image information of the target building (50) and the energy consumption information of the target building (50), the energy consumption status of the target building can be displayed.

[0079] In this way, based on basic information such as the building's footprint, use, and height, the building's exterior information can be generated. Furthermore, the energy consumption standard information can be generated based on an estimated building image by combining the generated exterior information with the building's window information. This energy consumption standard information can be used to determine whether the building is consuming unnecessary energy. By estimating the cause of energy waste, the system can guide building defect repairs. Based on this guidance, building remodeling can be implemented.

[0080] The technical features disclosed in each embodiment of the present invention are not limited to that embodiment, and, unless they are mutually incompatible, the technical features disclosed in each embodiment may be combined and applied to different embodiments.

[0081] Therefore, although each embodiment focuses on its own technical features, each technical feature can be applied in combination with each other as long as they are not mutually incompatible.

[0082] The present invention is not limited to the above-described embodiments and the attached drawings, and various modifications and variations are possible within the scope of those skilled in the art. Therefore, the scope of the present invention should be defined not only by the claims of this specification but also by equivalents thereof.
