Description

[0001] DESCRIPTION [0002] BUILDING ENERGY DIAGNOSIS METHOD, APPARATUS AND SERVER [0003]

The present invention relates to a technology for diagnosing building energy.

There are two major directions for countermeasures against depletion of fossil fuels and climate change caused by greenhouse gases. One is to replace the use of fossil fuels by developing renewable green energy technologies and the other is to reduce energy use and greenhouse gas emissions by increasing energy efficiency.

Building energy diagnosis technology belongs to the latter, which is a technology that grasps the state of buildings and suggests remedies to find areas where energy is wasting inefficiently.

In building energy diagnosis technology, the state of a building can be grasped in terms of energy consumption, especially insulation. For example, the state of a building can be classified as an insulation grade. According to this method, a building with a low insulation level is considered to have low energy efficiency.

The degree of insulation can be determined according to the heat conduction rate. The heat conduction rate is a value obtained by dividing the thermal conductivity by the thickness of the heat insulating material. The lower the heat conduction ratio, the higher the heat insulating grade.

It is important to accurately grasp the heat transfer rate of the building in the conventional building energy diagnosis technology that follows this series of processes. In the conventional building energy diagnosis technology, which determines the thermal insulation rating based on the heat transfer rate, it is difficult to accurately correct the building unless accurate corrective measures can be obtained without accurate diagnosis.

However, the heat conduction rate is calculated by knowing the thickness of the insulation used in the building and the thermal conductivity of the insulation. If there is no information on the insulation used in the building, the conventional technology based on the heat conduction rate is difficult to apply. In particular, when performing an energy improvement (for example, remodeling) project for an old building, it is difficult for a practitioner to actually understand the insulation information installed in the building. In this case, There may be a problem with the method.

SUMMARY OF THE INVENTION In view of the foregoing, an object of the present invention is to provide a technology for diagnosing building energy by detecting the insulation state of a building without direct information on the insulation material installed in the building.

According to another aspect of the present invention, there is provided a method of diagnosing energy of a building, the method comprising the steps of: acquiring an inside temperature and an outside temperature value of the building and thermally imaging the inside surface of the building; Transmitting the indoor temperature and the outdoor temperature value and the thermal imaging file to a building energy diagnosis server; And a step of receiving thermal insulation material information from the server and outputting the thermal insulation material information to a display, wherein the server determines the difference between the inside temperature and the inside surface temperature by the thermographic image file as a numerator, And the insulation parameter information is generated using a first parameter having a difference as a denominator.

According to another aspect of the present invention, there is provided an image processing apparatus comprising: a first photographing unit for photographing a thermal image; A communication unit for transmitting an indoor temperature and an outdoor temperature value of a building and a thermal imaging file of the building to a building energy diagnosis server and receiving insulation material information from the server; And a display for outputting the heat insulating material information, wherein the server calculates a difference between the inside air temperature and the outside air temperature by using the difference between the inside air temperature and the inside surface temperature of the building, Wherein the first parameter is used to generate the thermal insulation material information.

FIG. 2 is a block diagram of a building energy diagnosis system 100 (hereinafter, referred to as 'system') according to an embodiment.

2, the system 100 may include a thermal imager 222, an image imager 224, a display 226, a controller 212, a database 214, and the like. Each block may be located at the terminal 120 or at the server 110. For example, the thermal imaging unit 222, the image capturing unit 224, and the display 226 may be located at the terminal 120. The control unit 212 and the database 214 may be located in the server 110.

Each block can exchange information with each other through a communication unit. The terminal 120 may be located in the terminal communication unit 228 and the server 110 may be located in the server communication unit 216.

In the following description, the terminal 120 includes a thermal imaging unit 222, an image capturing unit 224, a display 226, and a terminal communication unit 228, and the server 110 includes a control unit 212, a database 214 and a server communication unit 216 will be described.

3 is an information flow diagram between a terminal and a server according to an exemplary embodiment of the present invention.

Referring to FIG. 3, the terminal 120 acquires or measures input information necessary for building energy diagnosis (S310).

The input information may be obtained by user input. Terminal 120 includes a display 226, which may be an input device that is capable of accepting user input in the form of a touch screen. The terminal 120 can acquire information inputted by the user through the touch screen. In addition, the terminal 120 may further include a user input device such as a keyboard and a mouse. Through the user input device, the terminal 120 can acquire information inputted by the user.

The input information may be measured through a measurement device included in the terminal 120. For example, the terminal 120 can measure the temperature through the thermo-radiographic part 222. The thermal imaging unit 222 is a device for measuring temperature and storing thermal images at one or more points. The terminal 120 can measure the temperature for one point through the thermal imaging unit 222 You can also measure the temperature for two or more points.

The terminal 120 may further include a measuring device other than the thermal imaging part 222. [ For example, the terminal 120 may include an azimuth sensor. The terminal 120 can measure the azimuth angle using the azimuth sensor. The azimuth sensor may comprise a gyro sensor and a geomagnetic sensor.

The terminal 120 may process the acquired or measured data to generate input information. For example, the terminal 120 may perform image processing on an image photographed through the image photographing unit 224 to identify characteristics of the image and generate the feature as input information. Of course, the photographed image itself may be used as input information.

The terminal 120 can transmit the input information generated by the acquisition, measurement or processing to the server 110 as described above (S320). At this time, communication between the terminal 120 and the server 110 can be performed by the terminal communication unit 228 and the server communication unit 216.

The server 110 may perform the energy diagnosis process using the input information (S330). The energy diagnostic process can be performed by the control unit 212. [ The control unit 212 may perform the energy diagnosis process using the input information received from the terminal 120 and the diagnostic data stored in the database 214. [

The server 110 may transmit the result of the energy diagnosis process to the terminal 120 as diagnostic information (S340).

The terminal 120 outputs the diagnosis information received from the server 110 through the display 226 to allow the user to check the diagnosis result on the building (S350).

4 is a detailed flowchart of the energy diagnosis process in FIG.

Referring to FIG. 4, the server 110 obtains indoor temperature and outdoor temperature of a building to be diagnosed (S402). Then, the server 110 obtains the inner surface temperature of the building (S404). In FIG. 4, the acquisition of the inside air temperature and the outside air temperature and the acquisition of the inside surface temperature are shown as different steps, but the two steps may be performed in one step. For example, the input information received from the terminal 120 may include both the indoor temperature, the outdoor temperature, and the inner surface temperature. The reference temperature means the indoor temperature of the building, the outside temperature means the outdoor temperature of the building, and the inner surface temperature means the indoor surface temperature of the building.

The server 110 calculates a first variable value as shown in the following Equation 1 by using the indoor temperature, the outdoor temperature, and the inner surface temperature received from the terminal 120 (S406).

The server 110 calculates the adiabatic performance index using the first variable (S408).

The process of calculating the adiabatic performance index using the first variable in step S408 will be described in more detail with reference to FIG.

5 is a graph showing the correlation between the first parameter and the heat conduction rate.

Referring to FIG. 5, the first parameter and the heat conduction rate have a proportional relationship. As the first parameter value increases, the value of the heat conduction rate also increases.

The heat transfer rate can be used as an indicator of the insulation performance of a building, particularly a building wall. The server 110 can use this heat conduction ratio as an index of heat insulating performance. The server 110 according to the embodiment does not calculate the heat conduction rate as a value obtained by dividing the thermal conductivity by the thickness of the heat insulating material according to the conventional method.

The server 110 according to an embodiment calculates the first variable and calculates the heat conduction rate according to the correlation between the first variable and the heat conduction rate.

The server 110 may store correlation information of the first variable and the heat conduction rate. The correlation information to be stored may be stored in the form of a table as shown in FIG. 5 (a) or as a function formula showing the graph shown in FIG. 5 (b) as data obtained through experiments.

The server 110 calculates the first parameter using the temperature of the inside air, the outside temperature and the inside surface temperature received from the terminal 120. Then, the first parameter value thus calculated can be substituted into the stored correlation information to calculate the heat conduction rate.

The following section focuses on the use of the heat transfer rate calculated from the first parameter as an index of insulation performance. However, depending on the embodiment, the first parameter may be used as a direct insulation performance index without using the heat conduction ratio as an insulation performance index.

Referring to FIG. 4 again after the description of step S408, the server 110 transmits heat insulation material information suitable for a building to be diagnosed to the terminal using the heat conduction rate calculated through the first variable (S410).

For example, the server 110 can transmit information on the heat insulating material having a superior heat insulating performance to the terminal as the heat conduction rate is higher. The user can remodel the building according to the insulation information to improve the insulation performance of the building.

An example of the thermal insulation information that the server 110 can provide to the terminal 120 will be described in further detail.

The server 110 may transmit to the terminal 120 thermal insulation information that allows a user to additionally install a thermal insulation material on the building to improve the thermal insulation performance of the building.

For example, the server 110 may transmit the heat insulating material type information suitable for the additional construction to the terminal 120. The terminal 120 may display on the display 226 the types of the heat insulating materials included in the heat insulating material type information in the form of a list. At this time, the server 110 may transmit the insulation improvement index improvement value information, which is improved when the respective insulation materials are installed, to the terminal 120 by including them in the insulation material information.

Fig. 6 is a diagram showing an improvement in insulation performance index which is improved when additional insulation is applied. Fig.

Referring to FIG. 6, if a thermal reflection material is additionally applied to a building wall having a thermal conductivity of 1.05, the heat conduction ratio can be improved to 0.36.

The server 110 can store the insulation improvement index improvement value information, which is improved upon construction by insulation material, in the database, and can transmit such information to the terminal.

The server 110 may include the construction cost information on the insulation material in the insulation material information and transmit the construction cost information to the terminal 120. When the server 110 transmits information on two or more insulation materials to the terminal 120, the server 110 may transmit the construction cost information on the respective insulation materials to the terminal 120.

The server 110 may transmit the energy saving cost information according to the construction of the thermal insulation material to the terminal 120 by inserting the information into the thermal insulation material information. The energy saving cost may vary depending on the area of the building, and the server 110 may further calculate the energy saving cost by using the area information of the building. The area information can be received from the terminal 120. Of course, the server 110 may calculate the energy saving cost by assuming the area of the building as a standard area.

The cost of energy savings may vary depending on the climate information of the area in which the building is located, and the server 110 may use the climate information to calculate energy savings costs. At this time, the server 110 may obtain climate information of the building using the building location information received from the terminal 120, while storing the climate information data for the region in the database 214. [

The energy saving cost may vary depending on the direction in which the insulation is installed in the building. The server 110 may calculate the energy saving cost by further using the insulation direction construction direction information. At this time, the server 110 may use the azimuth information received from the terminal 120 as the insulation material construction direction information.

The server 110 may generate the period information required to recover the construction cost by using the construction cost information and the energy saving cost information described above and transmit the generated period information to the terminal 120. [

On the other hand, the terminal 120 measures the inner surface temperature using the thermal image radiographing section 222. Since the thermal imaging unit 222 is a device capable of measuring temperature at various points, the terminal 120 acquires an inner surface temperature value for at least two points using the thermal imaging unit 222 .

At this time, the terminal 120 may transmit the inner surface temperature value to one of the acquired inner surface temperatures for at least two points to the server 110 as input information. In this way, when the terminal 120 transmits the inner surface temperature value for one point to the server 110, the server 110 can calculate the first variable value for the point.

However, the terminal 120 may transmit the inner surface temperature values for two or more points to the server 110 as input information. In some embodiments, the terminal 120 may transmit the thermal image file itself to the server 110. In this case, the server 110 may obtain an inner surface temperature value for a plurality of points stored in the thermal image file.

In this way, when the server 110 obtains the inner surface temperature value for two or more points, the following two embodiments can be implemented.

The first of the subembodiments is that the server 110 selects one of the inner surface temperature values for two or more points and calculates the first variable. In this case, the server 110 may select the lowest inner surface temperature value. According to Equation (1), the smaller the inner surface temperature value, the larger the first variable value. As the first variable value increases, it means that the adiabatic performance is poor. Therefore, the server 110 can use the lowest inner surface temperature value to improve the worst case of adiabatic performance.

The second of the lower embodiment is that the server 110 calculates the first variable using all the inner surface temperature values. In this case, the server 110 may select one of the calculated first variable values to proceed with the energy diagnosis process. As the first variable value increases, it means that the heat insulating performance is poor. Therefore, the server 110 can use the first largest variable value to improve the worst case of the heat insulating performance.

Figure 7 is an illustration of an infrared image of the building interior surface.

Referring to FIG. 7, it can be seen that the inner surface temperature of the portion 720 where the ceiling and wall face meet is lower than the ceiling portion 710. It is called heat bridging that the heat insulating performance is lowered at the portion where different members intersect, such as the portion 720 where the ceiling and the wall meet each other. When the server 110 uses the lowest internal surface temperature or uses the largest first variable value as in the above-described sub-embodiment, the server 110 can perform the energy diagnosis process for the heat- have.

Of course, the present invention is not limited to the above-described lower embodiment. In addition, the server 110 may generate a representative value (e.g., average value or median value) for the inner surface temperature value for two or more points to calculate the first parameter.

An embodiment has been described in which the first parameter value is used to calculate the heat conduction rate and the energy diagnostic process is performed using the first heat conduction rate. However, a large error may occur in the heat transfer rate calculated through the first parameter and the heat transfer rate of the insulation used in the actual building. For example, if there is a large measurement error in the trap temperature or outside temperature value, the first parameter is miscalculated and there is a large error between the rate of heat transfer calculated using this first parameter and the heat transfer rate of the insulation used in the actual building .

The server 110 can correct the heat conduction rate by using the information about the heat insulating material installed in the building. At this time, the information about the insulation material installed in the building can be indirectly estimated through the completion year information of the building. Because the building is subject to different regulations according to the year of completion, knowing the year of construction can estimate the information about the insulation used in the building.

The server 110 stores the insulation year information for the completion year in the database 214 and obtains the year information for the completion year from the terminal 120 and substitutes the information for the insulation year information for the year of completion to the insulation material .

In the foregoing, one embodiment has been mainly described in terms of the system 100 and the server 110. [ One embodiment will be further described below in terms of the terminal 120.

8 is a flowchart of a screen displayed on the display 226 of the terminal 120 according to an embodiment.

Referring to FIG. 8, the display 226 may display selection buttons for user-selectable building energy diagnostic types, such as wall diagnostics, window diagnostics, facility diagnostics, process generation, etc. (S802).

When the user clicks the wall diagnosis button, the display 226 outputs a button for inputting the outdoor temperature (outdoor temperature) and the indoor temperature (indoor temperature) (S804).

At this time, when the user clicks the outdoor temperature button, a window for inputting characters although not shown in FIG. 8 may appear. The terminal 120 may transmit the characters input by the user to this window to the server 110 as the outside temperature. The terminal 120 may further include a temperature sensor. In this case, when the user clicks the outdoor temperature button, the terminal 120 measures the temperature using the temperature sensor included therein, Can be transmitted to the roadside server 110.

When the user clicks the room temperature button, a window for inputting characters may be displayed although not shown in FIG. The terminal 120 can transmit the characters input by the user to this window to the server 110 as the betting temperature. The terminal 120 may further include a temperature sensor. In this case, when the user clicks the room temperature button, the terminal 120 measures the temperature using the temperature sensor included therein, To the server 110 as the temperature.

The terminal 120 can control the generation of a thermographic image file or transmission of the thermographic image file to the server 110 only when the difference between the indoor temperature and the ambient temperature is equal to or higher than a predetermined temperature. When the difference between the inside temperature and the outside temperature is small, the sensitivity of the first parameter increases due to a large molecule of the first parameter. In this case, a large error can be caused in the first variable even by a small noise or an error.

In this embodiment, the terminal 120 can control the display 226 to proceed to the next step S808 only when the difference between the indoor temperature and the outdoor temperature is equal to or greater than 10 degrees Celsius. If the process does not proceed to the next step (S808), thermal imaging is not performed.

When the input of the indoor temperature and the outdoor temperature is completed, a button for performing image shooting can be displayed on the display 226 (S808).

The image photographing button may be divided into various types, and may be classified into an image photographing button for a wall surface and an image photographing button for a heat bridge site according to an embodiment. When the image taking button is clicked, an image is taken by the image taking section 224 in the terminal 120.

The display 226 can simultaneously output the image photographed by the image photographing section 224 and the thermal image photographed by the thermal image radiographing section 222. [ In the case of deteriorated images, it is often difficult to grasp the shape. At this time, when the images are output simultaneously, the user can accurately recognize the shape of the part where the thermal image is captured while comparing the image and the thermal image.

The image shooting section 224 may further include an image processing function for the photographed image. At this time, when the light reflection on the surface of the object to be imaged is recognized through the image processing, the image shooting unit 224 can output a warning message to the display 226 or control the terminal 120 to prevent thermal imaging have. One of the methods for controlling the thermal imaging is to prevent the terminal 120 from outputting the button of the next step S812. If light reflection occurs on the surface, an error may occur in temperature measurement by thermography. The image capturing unit 224 may recognize the light reflection to output a warning message or control the terminal 120 so that the thermal image capturing is not performed, as described above in order to reduce such errors.

When the image shooting ends, a thermal image shooting button may be displayed on the display 226 (S812).

As shown in Fig. 8, the thermal imaging button can be displayed in subdivided directions. When the user clicks a button in each direction, the thermal image radiographing section 222 can take a thermal image. When the thermal image pickup button is divided by direction, the terminal 120 can transmit the thermal image pickup direction information (azimuth information) to the server 110 by including the thermal image pickup file in the thermal image pickup file. The server 110 can use this direction information (azimuth information) to calculate the energy saving cost or to generate the insulation information.

With regard to embedding azimuth information in the thermographic file, the terminal 120 may further include an azimuth sensor. The thermal imaging unit 222 acquires the azimuth angle information from the azimuth angle sensor at the time of thermal imaging and the terminal communication unit 228 further transmits the azimuth information acquired through the azimuth sensor at the time of transferring the thermal imaging file to the server 120 .

The thermal imaging unit 222 acquires thermal flow information about a surface on which a thermal image is captured, and can correct the thermal imaging file according to the thermal flow information and transmit the corrected image to the server 110. The surface temperature of a region where a heat flow (for example, a cold water pipe or a hot water pipe) is present may be distorted by this heat flow. The thermal imager 222 can acquire the heat flow information and correct the thermal imager file. The heat flow information can be obtained by user input. When the user views the thermal image displayed on the display 226 and displays the heat flow portion, the thermal imaging unit 222 determines that there is a heat flow in the relevant portion and can correct the temperature of the portion. As an embodiment of the correction, the thermal imager 222 can match the temperature of the portion indicated as having a heat flow with the temperature of the peripheral portion.

When the thermal imaging step S812 is completed, the display 226 can output the basic input button and the approval button (S816).

The user can click a basic input button and enter the completion year, direction, and area information of the building. The server 110 can calculate the energy saving cost when the insulation material is additionally constructed using this information.

When the user clicks the approval button, the display 226 may pop up the approval window. When the settlement is completed, the server 110 can cause the energy diagnosis process (S330 in FIG. 3) to proceed.

Upon completion of the approval step S816, the display 226 receives the information from the server 110, displays information on the current pass rate of the building, and outputs the heat insulating material information suitable for the heat conduction rate in operation S820.

The current heat transfer rate of the building can be determined according to the first parameter, which is calculated from the inside temperature, the outside temperature and the inside surface temperature. The server 110 may calculate the first parameter using the indoor temperature, the outdoor temperature, and the inner surface temperature information received from the terminal 120, and calculate the heat conduction rate using the first variable. Then, the server 110 may search the database 214 for the heat insulation material information corresponding to the calculated heat conduction rate, and transmit the information to the terminal 120.

The insulation information may include a list of two or more selectable insulation materials. At this time, if the user selects a suitable heat insulating material, the display 226 displays an improved heat conduction rate value (or an insulation grade) when the heat insulating material is additionally applied and displays the cost for the construction (S824). In addition, the display 226 displays the energy cost that can be saved by the additional construction, and further outputs the period information required to recover the construction cost to the energy saving cost (S824).

9 is a workflow diagram of a user utilizing a system according to an embodiment.

Referring to FIG. 9, the user first visits the field and proceeds with a tenant interview (S902). At this time, input information for driving the energy diagnosis process can be obtained from the tenant. At this time, it is also possible to check the housing status and obtain basic information. Basic information includes direction of the building, cladding material (enclosure surrounding the insulation), and completion year information.

After the basic survey, the user confirms the wall of the building (S904). Visually inspect where the insulation is weak on the wall. At this time, the energy diagnosis process can select surfaces to calculate the first parameter.

Then, the user confirms the indoor temperature and the outdoor temperature of the building (S906). The user can confirm the inside temperature and the outside temperature using a separate thermometer or the inside temperature and the outside temperature using the temperature sensor built in the terminal 120.

The user can also image images of major diagnostic areas while checking the temperature of the air and the temperature of the outside air (not shown).

The user can check the temperature of the inside air, the temperature of the outside air, and the main part image and determine the time point of the thermal imaging. For example, thermal imaging is preferably performed when the indoor / outdoor temperature difference is 10 degrees Celsius or more. In addition, when light reflection occurs, an error may occur in thermal imaging, so that the thermal imaging region can be selected differently depending on the position of the sun. In the case of excessive wind, it may affect the surface temperature, so it is desirable to shoot a thermal image when the wind speed is 3 m / sec or less.

Then, the user shoots a thermal image on the surfaces to calculate the first parameter by using the thermal image radiographing section 222 (S908).

The photographed thermal image is transmitted to the server 110 and a first variable is calculated. At this time, since the thermal image includes surface temperature values for a plurality of points, a plurality of first variable values can be derived.
