TECHNICAL FIELD [0001] The present invention relates to a device for calculating a sunshine amount and a method for calculating a sunshine amount,

The present invention relates to an apparatus for calculating an amount of sunshine and a method for calculating an amount of sunshine.

As the number of high - rise buildings increases, the importance of sunshine rights is also increasing. This is one of the important requirements for the real estate transaction as well as the quality of the individual residential environment, so it is required to accurately calculate and digitize the amount of sunshine.

In addition, development of natural energy is an important task, especially solar power energy has been put into practical use and widely spread. In the case of solar energy, it may be important to collect as much solar energy as possible during the day. Therefore, it is necessary to install a solar panel on the terrain where the solar energy can be collected as much as possible, and it is required to accurately calculate the amount of sunshine in the corresponding terrain.

Thus, the amount of sunshine in a building (e.g., an apartment complex, a downtown building) and the amount of sunlight in a particular terrain can be widely used for various purposes. However, the conventional technology provides only a simple viewpoint analysis according to the building direction, the space between the buildings, and the height of the building. In addition, the prior art is a numerical value calculated by a simple formula based on the seasonal southern mid-way and average sunshine hours in the amount of sunshine of a building or a terrain, and does not consider the effect of covering surrounding buildings or complicated terrain.

Therefore, it is necessary to develop an apparatus and a method that can calculate accurate sunshine amount considering the relationship between the surrounding building and the terrain of the building, and reduce the complexity at the location of the building where the actual sunshine amount is to be calculated.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to or limited by the embodiments. Like reference symbols in the drawings denote like elements.

The sunshine amount calculation apparatus and the method of calculating the amount of sunshine described in the present specification can calculate a relatively accurate sunshine amount in comparison with the prior art in consideration of the light blocking effect of the surrounding environment in a building complex or complex terrain.

1 is a block diagram showing an apparatus for calculating an amount of sunshine according to an embodiment of the present invention.

The apparatus 100 for calculating the amount of sunshine of the present invention may include a creating unit 110, a projecting unit 120, and a processing unit 130.

The creating unit 110 creates a virtual area having the direction in which the sunlight is incident vertically. That is, the creating unit 110 can create the virtual area in consideration of the direction in which the sunlight enters the ground. At this time, the virtual region may be a plane formed in any shape such as a rectangle or a circle. In addition, the virtual area may include a unit area divided into arbitrary sizes. For example, the creating unit 110 can create a virtual area composed of a rectangular plane perpendicular to the incident direction of sunlight. Furthermore, the creating unit 110 can be formed by dividing a rectangular plane so as to include a unit area having a width of 1 cm. A more detailed description of the virtual area will be described with reference to FIG. 2 and FIG. 3 which will be described later.

The creating unit 110 sets the solar water surface perpendicular to the direction in which sunlight is incident, taking into consideration the solar incident angle according to at least one of the time, the latitude, and the hardness on the surface occupied by the building, The virtual area can be created by dividing the solar water surface surface into a plurality of unit areas. That is, the creating unit 110 can set the solar water surface in consideration of the incidence time, the latitude, and the hardness of sunlight on the surface (ground) including the building for which the solar heat input amount is to be calculated. The solar water surface is perpendicular to the direction of sunlight incidence, and sunlight can be any area that is incident on the surface that contains the building. Then, the creating unit 110 can create a normalized area divided into unit areas within the solar water surface as a virtual area.

Furthermore, the preparation unit 110 can reset the solar water surface in accordance with the passage of time in consideration of the season. In other words, the creator 110 can reset the solar water surface at the corresponding time in consideration of the sun altitude which changes according to the season. For example, since the solar altitude varies depending on spring, summer, autumn, and winter at the same index and the same time, the creating unit 110 can set the solar water surface in consideration of the solar incident angle at the corresponding season and time.

For a more detailed description of the virtual region, reference is made to Fig.

FIG. 2 is a diagram illustrating a process of orthogonally displaying a building to be measured in a virtual area according to an exemplary embodiment of the present invention.

The creating unit 110 can set the solar water surface (210, dotted line) perpendicular to the direction in which sunlight is incident. The creating unit 110 can create the virtual area 211 (thick line) in consideration of the solar incident angle according to the time, the latitude, and the hardness with respect to the index including the plurality of buildings A and B. [ At this time, the creating unit 110 can create a virtual area 211 parallel to the solar water surface 210 and perpendicular to the sunlight. At this time, the creating unit 110 can create the size of the virtual area 211 as a part or the same as the solar water surface 210. In FIG. 2, the case where there are two buildings is described as an example, but the present invention is not limited thereto. A more detailed description of the process for calculating the amount of sunshine will be further described in the description of the projection part 120 below.

Referring again to FIG. 1, the creating unit 110 receives the horizontal, vertical, and height values of the building as building data, and models the shape of the building based on the building data. In other words, the building block 110 can input the horizontal, vertical, and height values of the building in which the solar incident heat inflow is to be calculated, and model buildings having the same width, height, and height. In this specification, the object to be modeled is described as 'building', but the present invention is not limited thereto. That is, the creating unit 110 can model not only buildings but also topographic features such as mountains, hills, and the like.

Also, the creating unit 110 may model the shape of the building in a three-dimensional graphic including polygonal surfaces according to the building data. That is, the creating unit 110 can model buildings and terrains as polygons such as triangles or squares. For example, it can be modeled as a hexahedron including a rectangular face with respect to a building, and a tetrahedron including a triangular face with respect to an acid. The creating unit 110 can determine and model the polygonal surface based on the input building data.

Further, when the building has a plurality of buildings, the building block 110 can further receive the building block data as the building data. In other words, when the building 110 includes a plurality of buildings in an arbitrary area, it is possible to input the interval value between the buildings. Therefore, when modeling the shape of the building, the location between the buildings can be determined and modeled. For example, the creating unit 110 can input 2 m as an interval value between the buildings A and B, and modeling the building A and the building B as a three-dimensional figure while spreading the distance between them to 2 m .

The projecting unit 120 orthogonally projects a building reaching the sunlight to the virtual area. That is, the projection unit 120 can orthogonally project the virtual area along the direction in which the sunlight is incident, so that the building surface can be projected to the virtual area where the building is located, and can pass through the building without the building. For example, in the case where the projecting part 120 is at the time of sunlight at a southern high altitude, the roof of the building can be orthogonalized to a virtual area.

In addition, the projecting unit 120 may project the modeled shape of the building onto the virtual area to perform orthographic projection. That is, the projecting unit 120 may vertically project a shape of a building modeled by a polygon into a virtual area, thereby realizing a virtual appearance of sunlight reaching the modeling building. For example, in the case of a building modeled as a rectangular parallelepiped, the projection unit 120 can project a plane of a rectangular parallelepiped corresponding to a roof of an actual building onto a virtual area to achieve orthographic projection, if it is time with sunlight at a southern height.

In addition, the projection unit 120 may vertically scan at least one of the edges of the graphic object constituting the orthographic projection so as to be within the virtual region. That is, the projecting unit 120 may vertically or alternately include one or both of the edges of the graphic object of the modeled virtual region, or all of them. For example, when orthogonal projection is performed on a building modeled as a rectangular figure, the projective part 120 may include at least one corner of the rectangle or may be orthogonal so as to include all four corners.

In order to explain the orthogonal projection process and the orthogonal projection virtual area more specifically, the description will be made with reference to FIG. 2 and FIG.

As shown in FIG. 2, the projecting portion 120 can orthogonally project the virtual region 211 in the solar light incidence direction. Partial areas 220 and 230 of the virtual area 211 are perpendicular to the building surfaces 221 and 231 of the building A and partial areas 220 and 230 of the virtual area 211 are formed on the building surfaces 241 and 251 of the building B 240, and 250 may be orthogonal. That is, the projecting part 120 projects the building surface 221 of the building A to a partial area 220 of the virtual area 211, and the building surface 231 of the building A is projected onto a part of the virtual area 211 The building surface 241 of the B building is projected onto the partial area 240 of the virtual area 211 and the building surface 251 of the B building is projected onto the partial area 250 of the virtual area 211, So that the image can be projected orthogonally.

FIGS. 3 and 4 are views for explaining the process of calculating the amount of sunshine through an orthographic virtual region according to an embodiment of the present invention.

Fig. 3 and Fig. 4 show a shape in which the buildings A and B in Fig. 2 are projected onto a virtual area. That is, the building surface 221 of the building A in FIG. 2 corresponds to a partial area 220 of the virtual area 211 in FIG. 2, a partial area 320 of the virtual area 310 in FIG. 3, And the building surface 231 of the building A corresponds to a partial area 230 of the virtual area 211, a partial area 330 of the virtual area 310, And may correspond to a partial area 430 of the area 410. The building surface 241 of the building B corresponds to a partial area 240 of the virtual area 211, a partial area 340 of the virtual area 310 and a partial area 440 of the virtual area 410, The building surface 251 of the B building may correspond to a partial area 250 of the virtual area 211, a partial area 350 of the virtual area 310 and a partial area 450 of the virtual area 410. [

In other words, FIG. 3 shows an area 320 where the surface of the building to which sunlight reaches the virtual area 310 overlaps with the virtual area 310, when the buildings A and B in FIG. 330, 340, and 350, respectively. At this time, the projection unit 120 may be orthogonal to include at least one of the corners of the areas 320, 330, 340, and 350 where the plane of the building to which the sunlight reaches overlaps with the virtual area 310. When the regions 320, 330, 340 and 350 shown in FIG. 3 are viewed as one rectangle, three corners of the regions 320, 330, 340 and 350 are out of the virtual region 310, It can be confirmed that it is included in the virtual area 310. That is, the projecting part 120 may vertically scan the buildings A and B so that one corner of the areas 320, 330, 340, and 350 is included.

4, the projection unit 120 may be configured to include all four corners of the areas 420, 430, 440, and 450 where the plane of the building to which the sunlight reaches the virtual area 410 overlaps, can do.

As shown in FIGS. 3 and 4, the creating unit 110 may include unit areas 311 and 411 constituting the virtual areas 310 and 410. In FIGS. 3 and 4, only some of the unit areas 311 and 411 are shown in the drawing, but all of the same size areas may mean a unit area.

Referring again to FIG. 1, the processing unit 130 calculates an orthogonally projected area of each building in the virtual area as the solar incident heat inflow amount of each building. That is, the processing unit 130 can calculate the solar incident heat inflow amount for the building by calculating an area for a partial area where the building surface overlaps the orthogonal projection virtual area. For example, the processing unit 130 can calculate an area of a roof of an orthographic building when the sunlight is at a high altitude. At this time, the solar heat input amount may be in units of watt.

In addition, the processing section 130 can calculate the solar incident heat inflow amount by counting a unit area overlapping the orthogonal projection. That is, the processing unit 130 can count the number of unit areas overlapping the building in the unit area in the virtual area, and calculate the solar heat input amount as the solar incident heat inflow. 3 for the sake of understanding.

The processing unit 130 calculates the solar heat input amount for some regions 350 of the orthogonal projection regions 320, 330, 340, and 350 shown in FIG. 3 when the unit area 311 ) Can be counted to calculate the solar heat input amount. The processing unit 130 can calculate the total solar heat input amount by multiplying the solar incident heat inflow amount per unit area 311 by 12 since the total number of the unit areas 311 overlapping the partial region 350 is 12 in total.

For example, the orthographic regions 240 and 250 of the B building shown in FIG. 2 correspond to the orthographic regions 340 and 350 shown in FIG. 3, and the processing unit 130 corresponds to the orthographic regions 340 and 350 ) Can be summed to calculate the amount of solar heat input to building B.

Referring again to FIG. 1, the processing unit 130 can count the overlapping unit areas satisfying the predetermined ratio with the orthographic deflection. Here, the 'selected ratio' may be a reference value of the ratio of overlap of the unit area and the orthographic region. For example, when the selected ratio is 50%, the processing unit 130 can count only a unit area in which the degree of overlap of the unit area with the orthographic region is 50% or more. 3 for the sake of understanding.

For the partial area 350 shown in FIG. 3, when the predetermined ratio is 50%, the processing unit 130 can count the unit area that satisfies the 50% ratio is 7.

Referring again to FIG. 1, the processing unit 130 may count the unit area overlapping the orthogonal projection at the time, and reset the solar incident heat inflow amount, as the sunlight water surface is reset. That is, when the solar water surface is reset in accordance with the season and time, the processing unit 130 can re-count the solar incident heat inflow amount by recounting an area where the unit area overlaps with the orthographically illuminated area.

Referring again to FIG. 1, when there is a fluctuation in the solar heat input amount based on the building data, the processing unit 130 can determine that overlapping occurs between the plurality of buildings according to the interval value. That is, since the building is positioned by the interval value according to the building data, the processing unit 130 calculates the surface area of the building (for example, the surface area of the building includes only the area of a part of the surface of the building in the direction in which sunlight is incident And the backside of a building where no sunlight is incident) can be identified as having overlap between buildings.

The processing unit 130 may check whether the solar incident heat inflow amount is smaller than the surface area of the plurality of buildings when overlapping occurs between the plurality of buildings according to the interval value. If the inspection result is not small, The calculated solar incident heat inflow amount can be discarded. Here, the surface area of the building may include only the area of a part of the surface of the building in the direction in which sunlight is incident. For ease of understanding, reference will be made to FIG.

For example, when the building A shown in FIG. 2 is located in front of the building B by the interval value according to the building data, and thus a part of the building surface of the building B does not reach the sunlight, Can be performed. First, the processing unit 130 can calculate the surface area of the buildings A and B as the sum of the areas of the areas 221, 231, 241, 242, and 251. The processing unit 130 can calculate the sum of the partial regions 220, 230, 240, and 250 of the orthogonal virtual region 211 as the solar incident heat inflow.

At this time, the processing unit 130 determines whether or not the areas 220, 230, 240, and 250 of the orthogonality regions 220, 230, 240, and 250 of the virtual area 211 are larger than the sum of the areas of the areas 221, 231, 241, If the sum of the orthographic regions 220, 230, 240 and 250 of the virtual region 211 is larger than the sum of the orthogonal regions 220, 230, 240 and 250 of the virtual region 211, , 250) can be discarded. This is because if the solar incident heat flux larger than the sum of the surface areas is calculated despite the overlap between the buildings, it is not reflected in the overlap between buildings or is not orthogonal due to the wrong incidence direction of the virtual area, . ≪ / RTI >

1, the processing unit 130 counts a unit area with respect to the surface of the building closest to the sun when at least some of the areas of the plurality of buildings occupy the same area in the virtual area, The shade of the building caused by the overlapping of the plurality of buildings can be processed. That is, when overlapping occurs between the plurality of buildings according to the interval value, the processing unit 130 calculates only the surface closest to the sun or the light source based on the distance from the building surfaces overlapping within the same unit area of the virtual area You can choose to target. At this time, the processing unit 130 can determine that the remaining surfaces are a shaded area in which sunlight is shielded by overlapping between buildings. In this way, the sunshine calculation apparatus 100 can save the calculation amount by replacing a complicated shielding operation to process only the nearest surface even though the number of surfaces of the building overlapping the same virtual area is large. Here, the surface area of the building may include only the area of a part of the surface of the building in the direction in which sunlight is incident. For ease of understanding, reference is made to Figs. 2 and 3.

In the case of the building surface 241 among the building surfaces 241 and 242 of the building B in FIG. 2, since the processing unit 130 is the surface closest to the sun, it is directly orthogonal to the partial area 240 of the virtual area, Can be regarded as a plane on which sunlight is incident on the building surface 241 of the B building. The region 240 can correspond to the region 340 as shown in FIG.

In the case of the building surface 242 of the building B in FIG. 2, when the building surface 242 is orthogonally projected to the virtual area, the processing unit 130 creates virtual areas 220 and 230 that are the same as the building surfaces 221 and 231 of the building A The processing unit 130 can confirm that the area 242 overlaps with the building planes 221 and 231 of the building A. [ At this time, the processing unit 130 can regard the building surface area selected to be closest to the sun for each overlapping unit area as the building planes 221 and 231 of the A building. That is, the area corresponding to the partial areas 220 and 230 of the virtual area may be the areas 320 and 330 in FIG. The processing unit 130 can regard the building surfaces 221 and 231 nearest to the sun individually as the planes incident on the sunlight. Thus, the surface to which the sunlight is incident can be referred to as the building surfaces 221 and 231 of the building A and the building surface 241 of the building B, and the building surface 242 of the building B is shielded by the building A Can be processed.

Referring again to FIG. 1, the processing unit 130 may further reflect the solar absorption rate, integrate the solar incident heat inflow with respect to time, and calculate the total solar incident energy amount at a certain time period as the sunshine amount. That is, the processing unit 130 can calculate the amount of solar incident energy in the building by further reflecting the solar absorption rate of each building. In addition, the processing unit 130 can calculate the solar incident energy amount by numerically integrating the solar incident heat inflow amount according to the time, and the solar incident energy amount unit may be joule or wat (Wh). In this specification, the apparatus 100 for calculating the amount of sunshine can provide the solar heat input amount or the total solar incident energy amount as the amount of sunshine.

The sunshine calculation device 100 effectively calculates the amount of sunshine for a building covered with sunlight due to the surrounding landform / artifact along the incident direction of sunlight, It is possible to provide the sunshine for the day.

In addition, the sunrise calculation apparatus 100 can reduce the computational complexity in the simulation by modeling the building using actual building data, creating the incident sunlight as a virtual area, and vertically modeling the building modeled in the virtual area.

FIG. 5 is a view for explaining a process of calculating an amount of solar incident energy according to an embodiment of the present invention.

First, the sunshine calculation apparatus 100 receives the building data, the terrain data, and the time-of-sun incident angle (510).

Next, the sunrise calculation apparatus 100 can model the building complex and the surrounding terrains as triangles or quadrilateral polygons based on the input data (520).

Next, the sunrise calculation apparatus 100 calculates the solar incident heat input amount (Watt) to reach the building and the terrain with the latitude and longitude of the location and the sun incident angle according to the season (530). When projecting the faces of the two buildings in a plane (virtual region) perpendicular to the direction of incidence of sunlight, the apparatus 100 for calculating the amount of sunlight can consider the closest surfaces to the solar vertical plane.

2 and 3, the sunlight amount calculation device 100 can consider that some surfaces 221, 231, 241, and 251 of the buildings A and B receive sunlight, In the case of the surface 241 of B, it can be regarded as receiving only a partial amount of sunshine because it is covered by the preceding A building. At this time, the area of the sunlight actually received by each of the surfaces 221, 231, 241, and 251 is a figure (220, 230, 240, 250 in FIG. 2 and 320, 330, 340, 350). The sunrise calculation apparatus 100 can easily calculate the projected area of the nearest object planes 320, 330, 340, and 350 projected to the respective lattice planes, with respect to the virtual area 310 divided by the square grid.

Next, the sunrise calculation device 100 introduces the solar absorption rate to the solar incident heat inflow amount, numerically integrates the process according to the time, and calculates the total solar incident energy amount (Joule or Wh) (540).

The apparatus 100 for calculating the amount of sunshine of the present invention can effectively calculate the ray blindness due to the surrounding terrain / object along the direction of the sun's rays. Therefore, the sunrise calculation apparatus 100 may have a calculation complexity O (n * m). In the case of KD Tree Ray Tracing, which is a widely used ray tracing technique in computer graphics in the prior art, the calculation complexity is O (nlogn). If one-to-one occlusion search is used for all sides, n ^ 2), where n is the number of surface polygons in the terrain / building and m is the average number of grid lines in the vertical plane of the solar surface per surface polygon.

In addition, the sunshine calculation device 100 can be used for the thermal efficiency of a building, the location of a suitable position of a solar panel, and the calculation of the amount of produced electricity, and ecological researches on ecosystem distribution according to the amount of sunshine of complex terrain (eg, My ecosystem), and to select suitable plants and crops for the terrain.

6 is a workflow diagram specifically illustrating a method for calculating the amount of sunshine according to an embodiment of the present invention.

First, the method of calculating the amount of sunshine according to this embodiment can be performed by the above-described sunshine amount calculation apparatus 100. [

First, the sunrise calculation device 100 creates a virtual area having a direction in which sunlight enters vertically (610). That is, the step 610 may be a process of creating a virtual area in consideration of the direction in which sunlight enters the ground. At this time, the virtual region may be a plane formed in any shape such as a rectangle or a circle. In addition, the virtual area may include a unit area divided into arbitrary sizes. For example, the sunrise calculation device 100 can create a virtual area composed of a rectangular plane perpendicular to the direction of sunlight incidence. In addition, the sunshine quantity calculation device 100 can be formed by dividing a rectangular plane so as to include a unit area having a width of 1 cm.

In addition, step 610 sets the solar water vertical plane perpendicular to the direction in which the sunlight is incident, taking into consideration the solar incident angle according to at least one of the time, the latitude and the longitude in the land occupied by the building, It is possible to divide the light-incident surface into a plurality of unit areas equal in width and height to create the virtual area. That is, the sunrise calculation device 100 can set the solar water surface in consideration of the incidence time, the latitude, and the hardness of sunlight on the surface (ground) including the building for which the solar heat input amount is to be calculated. The solar water surface is perpendicular to the direction of sunlight incidence, and sunlight can be any area that is incident on the surface that contains the building. Then, the sunrise calculation device 100 can create a normalized area divided into unit areas within the solar water surface as a virtual area.

Next, the sunrise calculation device 100 orthogonally projects the building reaching the sunlight to the virtual area (620). That is, in step 620, the virtual area may be orthogonalized along the direction in which the sunlight is incident, thereby allowing the building surface to be projected on the virtual area, and allowing the building area to pass therethrough. For example, in the case where the sunrise calculation device 100 is at the time of sunlight at a southern high altitude, the roof of the building can be vertically moved to a virtual area.

In addition, step 620 may be a process of orthogonally rendering at least one of the edges of the graphic object constituting the ortho-rectangle so as to be within the virtual area. In other words, the sunrise calculation device 100 may be orthogonalized so as to include at least one corner of a figure of a building in which a virtual region for ortho-projection is modeled. For example, when orthographic projection is performed on a building modeled as a rectangular figure, the apparatus 100 for calculating the amount of sunlight can be orthogonalized so as to include at least one corner of the rectangle.

Next, the sunrise calculation apparatus 100 can calculate an orthorectified area of each building in the virtual area by the solar incident heat inflow amount of each building (630). In other words, the step 630 may be a process of calculating the solar incident heat inflow amount for the building by calculating an area for a partial area where the building surface overlaps the orthographic virtual area. For example, when the sunrise calculation device 100 is at a time when there is sunlight at a southern high altitude, the area for the roof of the orthopedic building can be calculated. At this time, the solar heat input amount may be in units of watt.

In addition, the step 630 may be a step of counting the unit area overlapping with the orthogonal projection and calculating the solar incident heat inflow amount. In other words, the sunrise calculation device 100 can count the number of unit areas overlapping the building in the virtual area within the virtual area, and calculate the solar incident heat inflow.

In addition, step 630 may be a process of counting overlapping unit areas satisfying the predetermined ratio with the orthogonal projection. Here, the 'selected ratio' may be a reference value of the ratio of overlap of the unit area and the orthographic region. For example, when the predetermined ratio is 50%, the sunrise calculation apparatus 100 can count only a unit area in which the degree of overlap between the orthographic area and the unit area is 50% or more.

According to the embodiment, the step of setting the solar water surface of step 610 may be a process of resetting the solar water surface in accordance with the flow of time considering the season. In other words, the sunrise calculation apparatus 100 can reset the solar water surface at the corresponding time in consideration of the sun altitude which changes according to the season. For example, since the sun altitude varies depending on spring, summer, autumn, and winter at the same index and at the same time, the sunlight amount calculation apparatus 100 can set the solar water surface in consideration of the sun's incident angle at the corresponding season and time .

At this time, the step 630 may be a process of counting a unit area overlapping the orthogonal projection at the time, and resetting the solar incident heat inflow amount, as the solar water surface is reset. That is, when the solar water surface is reset according to the season and the time, the sunrise calculation apparatus 100 counts the area where the orthogonal projection area overlaps with the unit area, and re-counts the solar incident heat inflow amount.

According to the embodiment, the sunshine calculation apparatus 100 receives the horizontal, vertical and height values of the building as building data, and can model the shape of the building based on the building data. In other words, the sunshine calculation device 100 can input the horizontal, vertical, and height values of the building for which the solar incident heat inflow is to be calculated, and model a building shape having the same width, height, and height. In this specification, the object to be modeled is described as 'building', but the present invention is not limited thereto. That is, the apparatus 100 for calculating the amount of sunshine can model not only buildings but also topographical features such as mountains, hills, and the like.

At this time, the step 620 may be a process of projecting the modeled shape of the building onto the virtual area and performing the orthographic projection. That is, the sunrise calculation device 100 can implement a shape of a building modeled by a polygon orthogonally to a virtual area, so that a modeling building can virtually realize the appearance of sunlight. For example, in the case of a building modeled as a rectangular parallelepiped, the sunrise calculation device 100 can project the plane of the rectangular parallelepiped corresponding to the roof of the actual building to the virtual area and perform orthographic projection if the sunlight is of high altitude.

According to the embodiment, the sunshine calculation apparatus 100 can model the shape of the building in a three-dimensional figure including a polygonal surface according to the building data. In other words, the sunshine calculation apparatus 100 can model buildings and terrains as polygons such as triangles or squares. For example, it can be modeled as a hexahedron including a rectangular face with respect to a building, and a tetrahedron including a triangular face with respect to an acid. The sunshine quantity calculation device 100 can determine and model a polygonal surface based on input building data.

According to an embodiment, if the building is a plurality of buildings, the step of receiving the input of the step 610 may be a process of further inputting the interval value between the buildings as the building data. That is, when a plurality of buildings are included in an arbitrary area, the sunshine quantity calculation device 100 can receive the interval value between the buildings, and when the shape of the building is modeled in the modeling step, . For example, the sunshine quantity calculation device 100 may further input 2 m as an interval value between the buildings A and B. In the modeling step, the sunshine quantity calculation device 100 calculates the sunshine quantity of the building A and the building B as stereoscopic shapes The modeling can be performed such that the distance between the two becomes 2 m.

At this time, if there is a fluctuation in the solar incident heat inflow amount based on the building data, the step 630 can determine that overlapping occurs between the plurality of buildings according to the interval value. In other words, the sunshine quantity calculation device 100 determines that the solar incident heat inflow amount is smaller than the surface area of the building (for example, the surface area of the building is only the area of a part of the surface of the building in the direction And the backside of a building where no sunlight is incident can be excluded). If a smaller change occurs, it can be confirmed that there is overlap between buildings.

According to an embodiment, step 630 may include checking if the solar incident heat inflow is less than the surface area of the plurality of buildings when overlapping occurs between the plurality of buildings according to the interval value, The calculated solar heat input amount may be discarded. Here, the surface area of the building may include only the area of the surface of the building in the direction in which sunlight is incident. This is because if the solar incident heat flux larger than the sum of the surface areas is calculated despite the overlap between the buildings, it is not reflected in the overlap between buildings or is not orthogonal due to the wrong incidence direction of the virtual area, . ≪ / RTI >

According to an embodiment, step 630 may include counting the unit area for the surface of the building closest to the sun if the at least some of the areas of the plurality of buildings in the virtual area occupy the same area, And processing the shade of the building caused by the overlapping of the buildings with each other. In other words, when overlapping occurs between the plurality of buildings according to the interval value, the sunshine calculation apparatus 100 calculates only the surface closest to the sun or the light source based on the distance from the building surfaces overlapping within the same unit area of the virtual area It can be selected as an object of calculation. At this time, the sunshine calculation device 100 can determine that the remaining surfaces are shaded areas in which sunlight is shielded by overlapping between buildings. In this way, the sunshine calculation apparatus 100 can save the calculation amount by replacing a complicated shielding operation to process only the nearest surface even though the number of surfaces of the building overlapping the same virtual area is large. Here, the surface area of the building may include only the area of a part of the surface of the building in the direction in which sunlight is incident.

According to the embodiment, the amount of sunshine calculation device 100 further reflects the solar absorption rate, and integrates the solar incident heat inflow amount with respect to time to calculate the total solar incident energy amount at a certain time interval as a sunshine amount. In other words, the sunrise calculation device 100 can calculate the amount of solar incident energy in the building by further reflecting the solar absorption rate of each building. In addition, the sunrise calculation apparatus 100 can calculate the amount of solar incident energy by numerically integrating the solar incident heat inflow amount according to the time, and the unit of solar incident energy amount can be a joule or a wattage Wh have. In this specification, the apparatus 100 for calculating the amount of sunshine can provide the solar heat input amount or the total solar incident energy amount as the amount of sunshine.

This method of calculating the amount of sunshine effectively calculates the amount of sunshine for a building covered with sunlight due to the surrounding topography / ground due to the incidence direction of the sunlight so that the amount of sunlight for sunlight that can be substantially received at the place where the building is actually located .

In addition, the method of calculating the amount of sunshine can reduce the computational complexity in the simulation by modeling the building through the data of the actual building, creating the incident sunlight as a virtual area, and vertically modeling the building modeled in the virtual area.
