However, this conventional technology has the following problems. As described above, it takes several months (approximately 5-6 months) to calculate the required energy after inputting the information into the simulation tool. Therefore, in order to calculate the required energy in order to calculate the required energy when various conditions, for example, the size of the building or the operating environment, are changed, enormous time and cost are required to calculate the required energy. There was this.

According to an embodiment of the present invention, a method for generating required energy data is to prepare a simulation table for required energy of buildings having various conditions as described above. In other words, the required energy for each case is simulated under conditions such as various building sizes and azimuth angles, various room temperature or humidity conditions, and various outside air temperatures, and the calculated values are prepared in a table.

According to the present invention, if the required energy values are prepared in a table, the required energy values can be conveniently and quickly calculated by reading the corresponding table values for each condition of the building to be calculated.

To do this, first perform 3D modeling of standard buildings, input building information, calculate the required energy by using simulation tools, and operate the simulation tools while continuously changing the variables for the building information. You will create a table of simulation data for the required energy of the buildings.

Such a present invention will be described with reference to FIGS.

First, a standard building is set by performing a first step S100 of performing 3D modeling of a building. The 3D modeling may use a well-known SKETCH UP program. The third step S300 of operating the simulation tool is performed by performing a second step S200 of inputting the modeled building information into a simulation tool. The simulation tool may use software such as Trnsys, Energy Plus, DOE-2, ESP-r and the like as described above.

The third step (S300) performs a fourth step (S400) for calculating the required energy amount by simulating the energy consumption of the building for a specific condition.

On the other hand, the present invention is a fifth step of determining whether the change of the input information to implement the various conditions by completing the required energy to the table after calculating and calculating the required energy for the various conditions as described above is completed Perform (S500). When the change of the information input by the fifth step S500 is not completed, the sixth step S600 of changing the information and performing the second step S200 again is performed, which will be described separately.

On the other hand, when the change of the information input by the fifth step (S500) is completed, the seventh step (S700) of creating the necessary energy for the table in a variety of conditions according to each changed information to the table is carried out separately Explain.

In addition, the information input to the simulation tool in the second step (S200) includes building information, operating environment and weather information. At this time, the building information includes building size, building orientation, window ratio, shadow ratio, and the operating environment includes humidity and temperature for the room of the building. The weather information includes the outside air temperature.

Meanwhile, as described above, the present invention calculates the required energy under various conditions, and for this purpose, after changing the related information in the sixth step S600, the changed information is input to the simulation tool by the second step S200. do.

In the sixth step S600, the building size is divided into a horizontal direction size, a width direction size, and a height direction size of the building, and is changed by increasing a different size for each size by a specific multiple. For example, in the first step (S100), the horizontal direction of the building modeled as 3d is defined as the x-axis, the width direction is y and the height direction is z, and then the size of the x, y, x, direction is defined. (For example, 1.1 times 1.2 times, 1.3 times, ... 2 times, 3 times, 4 times, etc.).

In addition, the building orientation is changed by a specific orientation. For example, it simulates by inputting each direction changed 30 degrees clockwise from north.

The window ratio is changed by increasing the ratio occupied by windows in a building by a specific multiple, for example, 10%, 20%, 30%, and the like.

The shadow ratio is changed by increasing the proportion of the shadowed area in the building by a specific multiple, and for example, 10%, 20%, 30%, etc. as described above.

The humidity and temperature for the room of the building which is the operating environment is increased by a specific multiple, and the weather information is changed by increasing the outside temperature by a specific temperature interval.

After changing the various conditions in the sixth step (S600) and input in the second step (S200) to calculate the required energy by the simulation.

On the other hand, by the seventh step (S700) the necessary energy for the building under various conditions is created as a table.

In this case, as shown in FIG. 4, the size of each building is defined as the first condition A1, and the respective building orientation with respect to the first condition A1 is the second condition A2.

For example, as described above in the size of the building, the size of the x direction is increased 1.1 times 1.2 times, 1.3 times, ..., 2 times, 3 times, 4 times as the A1 condition, and then the size of the y direction is 1.1 times 1.2 times. , 1.3 times, ..., 2 times, 3 times, 4 times, then increase the z direction size 1.1 times 1.2 times, 1.3 times, ..., 2 times, 3 times, 4 times (A1_1 ~ A3_i) In this case, for each A1 condition, each orientation, for example, north is 0 degrees and 30 degrees (or larger or smaller) in the clockwise direction is changed (A2_1 to A2_i).

Similarly, each window ratio for each second condition A2 is arranged as the third condition A3, and each shadow ratio for the third condition A3 is the fourth condition A4. Arrange.

The operating environment conditions for the fourth condition A4 are set as a table with the fifth condition A5.

On the other hand, the first condition (A1) to fifth condition (A5) is a gaseous condition is arranged for each outside air temperature. That is, as shown, for example, the ambient air temperature between -40 degrees Celsius and 50 degrees Celsius is arranged in a predetermined temperature interval (for example, 10 degrees Celsius), and a simulation value corresponding to each ambient temperature, that is, required energy is calculated. To arrange.

According to the present invention, it is possible to easily calculate the required energy for each building to be calculated by simulating the required energy for each condition from the table.

On the other hand, after creating the table in the seventh step (S700), and performing the eighth step (S800) to find the required energy of the building to be analyzed from the data table.

In this case, in the eighth step S800, when some of the conditions of the data table and the building to be analyzed do not coincide, the necessary energy data of the inconsistent condition is secured and then linearly generated by the data adjacent to the inconsistent condition. The interpolation method is used to calculate the required energy.

As shown in FIG. 4, the size of each building is referred to as the first condition A1, and each building orientation with respect to the first condition A1 as the second condition A2. The window area ratios for the second condition A2 are arranged as the third condition A3, and the shadow area ratios for the third condition A3 are the fourth condition A4. Arrange as follows. The operating environment conditions for the fourth condition A4 are set as a table with the fifth condition A5. At this time, the first condition (A1) to the fifth condition (A5) are arranged in the weather conditions, that is, for each outside air temperature. That is, as shown, for example, the ambient air temperature between -40 degrees Celsius and 50 degrees Celsius is arranged in a predetermined temperature interval (for example, 10 degrees Celsius), and a simulation value corresponding to each ambient temperature, that is, required energy is calculated. To arrange.

After such a table is created, it is necessary to find the required energy of a building that meets a predetermined condition.

However, in the second step S200, some of the conditions of the data table and the analysis target building may not match. In this case, the necessary energy is calculated using linear interpolation based on the data adjacent to the inconsistent condition.

For example, as shown in Figure 5, if the data corresponding to the condition (A2) for the azimuth angle of the above conditions does not appear in the data table, the need for inconsistent conditions by the interpolation method using Equation 1 below Calculate the energy.

[Equation 1]

Where Y is the required energy of the building to be analyzed, and L11 and L12 are the ratios of low and high values adjacent to the data of inconsistent conditions, and E11 and E12 are the low values adjacent to the data of inconsistent conditions. And the respective required energy corresponding to the high value.

As shown in Fig. 5, if the outside temperature is 20 ° and the inconsistent condition is 48 ° as the orientation A2, it cannot be found in the data table. In this case, the required energy for the case where the orientation factor is 48 ° is calculated by Equation 1 above.

At this time, since L11 and L12 are ratios for the low value and the high value respectively adjacent to the data of the inconsistent condition, the low value is 45 ° and the high value is 50 ° in the present embodiment. At this time, since the mismatched orientation factor is 48 °, the ratio L11 is 3 and L12 is 2. By each of these ratios, the weighting value existing between the data of the inconsistent condition and the adjacent data can be reflected in the required energy.

Further, E11 and E12 are respective required energy corresponding to low and high values adjacent to data of inconsistent conditions. In this case, there are a plurality of required energy data corresponding to the low value and required energy data corresponding to the high value. In this case, the average value of the required energy data is taken. That is, the required energy corresponding to the low value (45 °) is 12, 12, 13, 14, 15, 16, 17, and 18, respectively. Taking the average of these values gives 14.625, which is E11. In addition, the required energy against the high value (50 °) is 13, 15, 17, 18, 19, 20, 21, 22, respectively. The average of these values is 18.125, which is E12.

Therefore, Y to be obtained is 16.725 by Equation 1, and when there is one mismatch condition by this method, the required energy of the building to be analyzed can be calculated.

If data corresponding to two conditions do not appear in the data table as shown in FIG. 6, calculating a plurality of necessary energy data for the inconsistent condition by interpolation using Equation 2 below; A step of calculating the required energy of the building to be analyzed is performed by averaging a plurality of calculated required energy.

[Equation 2]

At this time, Y1, Y2: the required energy of the building to be analyzed for the inconsistent condition, L11, L12, L21, L22, L23, L24 are ratios for the low and high values adjacent to the data of the inconsistent condition, respectively. , E11, E12, E21, E22 are the energy required for each of the low and high values adjacent to the data of inconsistent conditions.

On the other hand, when there are two inconsistent conditions, there is a low value and a high value for one condition, for example, a mismatched azimuth condition, and another inconsistency condition, for example, a creation condition, exists for a low value. Since the window condition is also present, the energy consumption calculated is two (Y1, Y2) and the average is calculated to calculate the required energy of the building to be analyzed.

For example, if the azimuth condition (A2) is 48 ° and the condition (A3) for the window area is 30 as a mismatched condition, L11 and L12 become 3 and 2, respectively. L21 and L22 and L23 and L24 are ratios of adjacent low and high values of the window area condition (A3), so L21 and L22 are 1 and L23 and L24 are 8 and 13. By each of these ratios, the weighting value existing between the data of the inconsistent conditions and the adjacent conditions can be reflected in the required energy.

In addition, there are two (Y1, Y2) energy requirements to calculate, and two energy pairs adjacent to each other are needed. That is, one of the two pairs has a plurality of low values E11, so if the average is 12.75, the high value E12 is 16,75. In addition, among the other pairs of required energy, the low value E21 is 15.75 and the high value E22 is 20.5. By putting these values in Equation 2 and calculating the average of each of Y1 and Y2, the required energy of the building to be analyzed can be calculated.

In addition, as shown in FIG. 7, when data corresponding to three conditions do not appear in the data table, calculating a plurality of necessary energy for inconsistent conditions by interpolation using Equation 3 below. In addition, calculating the required energy of the building to be analyzed by calculating the average of the plurality of calculated required energy.

[Equation 3]

At this time, Y1, Y2, Y3, Y4 is the required energy of the building to be analyzed for the inconsistent conditions, L11, L12, L21, L22, L23, L24, L31, L32, L33, L34, L35, L36, L37 and L38 are ratios for low and high values adjacent to data of inconsistent conditions, respectively, and E11, E12, E21, E22, E31, E32, E41, and E42 are low values adjacent to data of inconsistent conditions and It is the energy required for each of the higher values.

On the other hand, if there are three inconsistent conditions, the required energy is calculated to be four (Y1, Y2, Y3, Y4), and the average is calculated to calculate the required energy of the building to be analyzed, which is similar to the above. Omit.

Of course, there may also be a case where there are four inconsistent characteristic factors, which may be inferred by applying the method of the present invention to calculate the energy consumption of the building to be analyzed.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains can realize that the present invention can be carried out in other specific forms without changing the technical spirit or essential features. I can understand.

Therefore, the above-described embodiments are to be understood as illustrative and not restrictive in all respects, and the scope of the present invention described in the above detailed description is represented by the following claims, and the meanings of the claims and All changes or modifications derived from the scope and equivalent concepts thereof should be construed as being included in the scope of the present invention.
