Due to the recent economic development and expansion of urban functions, most new buildings are aiming for high-tech, high-rise, and large-scale buildings, and the facilities of buildings consume relatively high energy in consideration of the convenience of maintenance and the increase and stability of office equipment. Building of form to say is done.

On the other hand, a lot of research has been conducted to reduce the energy consumed in the building, for example, air conditioning, power, and lighting systems are separately constructed and the energy management system is operating based on this. In particular, many studies have been conducted to improve energy management efficiency, such as air conditioner performance diagnosis, control and management technology, and analysis of energy consumption to buildings based on IT technology. .

However, the existing researches on energy management efficiency of the same kind of equipment are technologies that can maximize energy savings by comprehensively analyzing and managing the energy consumption of the air conditioning, power, and lighting control systems that are operating in buildings. For the development of the situation is insufficient.

In particular, energy plus developed by Lawrence-Berkeley National Laboratory with support from the US Department of Energy, for example, a program or system to simulate the amount, distribution, or trend of energy consumed by buildings under certain conditions. Energy simulation tools, such as Energy Plus, are complex enough to run a program that only a few experts can run, and the simulation results are also provided as text files in raw raw data.

For this reason, it is difficult for an administrator to continuously manage a building to view simulation results, and thus, accessibility and utilization of a built building energy simulation system are low.

The present invention has been conceived based on these points, and the problem to be solved by the present invention is to provide a building energy simulation results analysis system having high accessibility and utilization of the energy simulation results.

A more detailed example of the building energy simulation result analysis system according to the present invention will be described later in the embodiments with reference to the drawings.

The input unit 110 receives simulation data necessary for the simulation unit 120 from the outside. The input unit 110 may collectively refer to various input means for inputting all types of information desired by a building manager or a user using the building energy simulation result analysis system 100 according to the present embodiment.

For example, the input unit 110 may include a keyboard used for inputting text-based information, which is generally adopted in a desktop or laptop computer, or a mouse that facilitates menu selection or command input based on coordinates. have. In addition, various types of readers that directly transmit information may include, for example, a barcode reader or a smart tag reader, and may include an optical input device such as a CD or a DVD, a flash memory type card reader, or a USB connected external storage medium. It may mean a configuration connected with.

The input value 10 input through the input unit 110 may include all variables for simulating building energy consumption. Specifically, the input value 10 that may be input through the input unit 110 is a first input value for the condition of the building itself, such as the interior area, the number of floors, the location, the location of the building, the number of equipment and equipment included in the building. A second input for operating conditions, including the capacity of each equipment / equipment, the number of employees in the building, the number of full-time workers on each floor, and the third input for external environmental conditions such as outside temperature, weather, humidity, etc. It may include.

Since the amount of energy consumed by a building for a predetermined time may be changed by a myriad of variables, the building is not limited to the first to third input values described above. 110 may be provided.

A user of the system may input a plurality of input values 10 for performing a building energy simulation to the input unit 110 to perform a simulation. The plurality of input values 10 may be changed to generate a building energy consumption pattern under various environments. I can figure it out.

The simulation input value 10 may include a simulation target pattern 50 (see FIG. 4). That is, the user may output not only the input value 10 required for the simulation through the input unit 110 but also the target pattern 50 for the purpose of performing the simulation, and finally output the desired result in a desired form. have. This will be described later in detail.

As shown in FIG. 2, the simulation unit 120 performs a simulation on a building energy consumption state based on various input values 10 input through the input unit 110, and thus, the first result value 20. Will print

According to a presentation by the World Business Council for Sustainable Development (WBCSD), the total energy consumed in a building accounts for 40% of the world's energy consumption. Energy bills such as heating bills cannot be used for quantitative analysis. Building energy simulation is needed to analyze quantitative and dynamic energy performance through numerous variables such as weather conditions, surrounding environment, building envelopes, windows, and air conditioning facilities.

Therefore, building managers can identify the current trend of energy consumption in the building through continuous building energy simulations, and make reasonable judgments as to which input value (10) can be increased or reduced to reduce energy consumption. The simulation can be repeated to determine the optimal energy consumption conditions in the current building.

As the simulation engine used in the simulation unit 120, a known energy simulation engine, for example, BLAST, Bsim, eQUEST, EnergyPlus, TRANSYS, ESP-r, DOE-2, etc. may be used without limitation.

The simulation unit 120 generates a virtual building according to the input condition through a predetermined modeling process based on the input value 10, and how much the total energy consumption is for a predetermined time, and how much energy is used for each zone for each floor. For example, the energy consumption for each plant can be calculated separately, eg boiler energy consumption, air conditioning system energy consumption and refrigeration energy consumption.

In addition, the simulation unit 120 may perform cost modeling such as construction cost or equipment maintenance cost in advance before the completion of the building, and may perform environmental load modeling such as greenhouse gas emissions such as carbon monoxide (CO) or carbon dioxide (CO2). It may be.

As such, the first output value 20 that is the building energy simulation result according to the input value 10 may be obtained through the building energy simulation result analysis system 100 according to the present embodiment.

However, the first result value 20 output by a known energy simulation engine, for example, BLAST, Bsim, eQUEST, EnergyPlus, TRANSYS, ESP-r, and DOE-2 as a simulation result is raw data of a text type (raw data). ) Form.

Therefore, it is necessary to analyze the first result value 20 directly by an energy simulation expert to simplify it. That is, the energy simulation expert first searches for a file including desired data among the plurality of text files generated as the first result value 20, and then generates a report by reading the required data directly from the retrieved file or selecting desired data. It is necessary to process a predetermined task by reading the included file with a separate data extraction program.

When building energy simulation is performed to analyze the energy consumption pattern after completion before building, there is no problem because the energy analysis specialist performs the work. An inexperienced building manager will identify building energy trends.

Therefore, even if a general building manager executes a simulation by putting input values into a pre-built building energy simulation, since the data derived as a result is raw data in text form, it is difficult to analyze the data and has low utilization. As a result, continuous building energy simulations are difficult to perform, and efficient management of building energy is difficult to achieve. On the other hand, it is not economical to ask the energy analysis expert to analyze the results every time the building energy simulation is performed periodically.

As shown in FIG. 3, the building energy simulation result analysis system according to the present embodiment includes a data processor 130 for converting the first result value 20, which is raw data, into the processed second result value 30. can do.

The data processor 130 may process the first result 20 to derive the second result 30 and store it in the database 140.

The data processor 130 loads the first result value 20 in the form of a plurality of text files on the memory and / or the storage space, and the first result value loaded on the memory and / or the storage space. Index unit 132 for generating an index list by performing an indexing operation so as to quickly search the components of (20), an index search unit for accessing a desired element of the index list to search for a value (value) (133) a result generator 134 for generating a dataset in a format different from the first result value 20 based on the plurality of retrieved values, and the data set generated by the result generator 134; It may include a result storage unit 135 for storing the converted data transmitted to the database unit 140.

The load unit 131 loads the first result value 20 in the virtual memory area or the physical storage space. The load unit 131 may activate the cache function to increase the access speed of the first result value 20. As such, the access speed may be increased by loading the first result value 20 in the form of a file into the memory area.

The index unit 132 may extract the header information of the first result value 20 by accessing the memory area and perform an indexing operation based on this to generate an index list of the first result value 20. The generated index list may be in the form of directly referencing a memory address directly accessible to the desired data. Based on the index list, a desired value of the first result value 20 can be quickly accessed.

The index search unit 133 may search for a necessary value by accessing a desired element of the index list. For example, as a result of the building energy simulation, the first result value 20 may include lighting electricity usage, facility electricity usage, and energy production. We can access to obtain the memory location that stores the lighting electricity usage value of the area and then access the memory location to extract the required value.

The index search unit 133 may selectively search for values according to the data desired by the simulation worker. For example, assuming that the simulation target is six elevators of Nos. 1 to 6 that operate in a building, and all elevators currently operate all floors, Nos. 1 to 3 run only odd floors. Unit 6 can simulate changes in energy consumption before changing elevators to run even-numbered floors. In order to understand how the energy consumed by the elevator changes, the elevator is divided into an even-floor elevator and an odd-floor elevator. In this case, the energy consumption of the odd-numbered elevators can be determined separately by selectively searching only the values of the first and third elevators, and the energy consumption of the even-numbered elevators can be separately determined by selectively searching the values of the fourth and sixth elevators. I can figure it out.

The result generator 134 may store the value selectively retrieved by the index searcher 133 in a separately generated dataset. Since the result corresponding to the result value to be obtained by the simulation is not the entire first result value 20 but a value selectively queried by the index search unit 133 therefrom, these values are separately stored in the data set and the operator Can selectively output only the desired data.

The result storage unit 135 may output the second result value 30 by storing the generated data set in a physical space or a memory area. At the same time, the data set may be transmitted to the database unit 140 to store simulation results, and later, the simulation results may be checked by querying past simulation results.

The database unit 140 may be a physical or logical area including a plurality of simulation result information. The database unit 140 may include one or more data tables, and each data table may have a plurality of columns and corresponding values.

The database unit 140 may store the data set received from the data processing unit 130, and may return the result value data generated by the query statement transmitted from the data processing unit 130 to the data processing unit 130 again. .

The database unit 140 may be provided in an electronic form and may be in the form of a program driven by an information processing apparatus including a microprocessor. For example, it may be in the form of Oracle DBMS of Oracle, MS-SQL DBMS of Microsoft, SYBASE DBMS of Sybase.

The database unit 140 may include an index list generated by the index unit 132 to quickly search the stored simulation result information.

4A to 5, the interface output unit 150 is a graphical user interface that is finally output to the simulation operator based on the second result value 30 derived by the data processing unit 130. 40 may be generated.

The data processor 130 generates an interface 40 corresponding to the second result value 30 generated based on the first result value 20 in the raw form, thereby allowing the user to intuitively display the second result value 30. ) Can be recognized. That is, the second result value 30 in the form of processed data may not be directly output, but may be output in correspondence with the graphic user interface 40.

As shown in FIG. 4B, the graphical user interface 40 may be composed of a fixed area 41 and a variable area 42. The fixed area 41 is a common area constituting the graphic user interface 40 and is a part that remains the same regardless of the change of the second output value 30. On the other hand, the variable region 42 is a portion into which a part and / or the entirety of the second output value 30 is inserted. When the second output value 30 is changed, the variable region 42 may also be changed.

On the other hand, the fixed region 41 does not mean a constant region, and as described above, it may be changed to another output mode according to the target pattern 50 of the simulation. That is, the interface output unit 150 may generate different visualized interfaces according to the simulation target pattern 50 and provide them to the user.

Specifically, referring to FIG. 5, the interface output unit 150 may include a control unit 151 managing a plurality of output modules, and first to third output modules 152 and 153 controlled by the control unit and outputting different interfaces. , 154).

The first output module 152 may output the predicted energy consumption and the total predicted energy usage for each area of the building. The first output module 152 provides an overall energy forecast usage amount of the building based on the input second result value 30, so that an energy saving method suitable for energy consumption of each zone can be determined in advance.

The second output module 153 may output the load applied to each equipment in the building. The second output module 153 calculates the capacity of the equipment in advance and calculates the maximum load value and the maximum heating and cooling load value of the equipment, and based on this, the equipment that selects the appropriate equipment or falls short of the applied load value is new equipment in advance. Can be replaced.

The third output module 154 may compare and output the current energy usage and the predicted energy usage of the building. The third output module 154 has the purpose of identifying the effect of the improved energy use compared to the current state of energy use, and the energy saving amount and the energy reduction rate and / or environmental impact reduction rate, etc. Output the interface.

As described above, the building energy simulation result analysis system according to the present embodiment provides the user with a second output value processed based on interfaces generated by different output modules according to the purpose of the simulation, so that the user intuitively recognizes the simulation result. Based on the simulation results, building energy can be managed efficiently.

It is difficult to determine whether the desired result is listed in.

Subsequently, the first result value transmitted to the data processor 130 is processed and transformed into a second result value in the form of a processed data set (S14). The series of processes performed by the data processor 130 is as described above.
