Description

  The present invention relates to a system that can easily diagnose the heat insulation performance by simulating the energy saving effect obtained when installing a heat insulation window in an existing house, particularly in an existing house using a single-layer glass in the opening, It is a system for diagnosing the effect of heat insulation performance of an opening obtained by attaching a heat insulating window formed of a material having a heat insulating effect to a single layer glass to form a double window.

  In recent years, energy saving has become an inseparable matter in daily life, and the spread of double-glazed glass with a high thermal insulation effect is increasing in the openings of newly built buildings. However, many of the openings in existing houses and apartment buildings use single-layer glass, and heat insulation windows made of heat-insulating materials are attached to the single-layer glass of these buildings. Insulation refurbishment to make double windows is required.

  In a conventional apparatus for evaluating the dwelling performance of a house, how the dwelling performance changes depending on the type of glass used in the house is evaluated by simulation. For example, a glass database 1 that stores characteristics of various types of glass used for residential use, an environment / needs acquisition unit 2 that acquires a family structure of a consumer, regional information, and a client's need level, and specific data from the glass database A residence comprising a glass selection unit 3 to be selected, a performance evaluation unit 4 that evaluates the residence performance when the selected glass is used in a model residence prepared in advance in association with the environment and needs, and an output unit 5 that outputs the evaluation result In the performance evaluation system, the characteristics of the glass selected by the glass selector 3 are acquired from the glass database 1, and the five characteristics of light, heat, sound, humidity, and safety are associated one by one with the five rooms of the model residence. Evaluate the performance and display or graph the evaluation results of illuminance distribution, temperature distribution, sound insulation effect, indoor condensation, impact load resistance and glass breakage. Automation display technology is described in Patent Document 1.

There is also a simulation device that performs quantitative evaluation of indoor thermal environment and air conditioning energy saving performance at the planning and design stage. For example, input processing means can be used for building use, area, orientation, exterior wall type, window glass material, blind type, perimeter Enter the air conditioning method and other building specifications, edit the data for calculating the thermal environment index, annual heat load, and energy saving index based on the above-mentioned input data by the data editing processing means, and the thermal environment index, annual Patent Document 2 describes a technique for calculating and outputting a heat load and an energy saving index.

  However, as described above, the apparatus for evaluating the performance of the living environment of a conventional house uses a model house prepared in advance, and has five characteristics of light, heat, sound, humidity, and safety of glass selected from a glass database. A graph or a graph showing the evaluation results weighted according to the needs level of the unknown, latent, abstract manifestation, and manifestation of the customer, with the performance corresponding to the five rooms of the model residence one by one. Animated display. Therefore, there is a problem that cannot be applied to the present invention for evaluating the heat insulation performance such as annual load and power consumption when a heat insulation window is attached to the single-layer glass installed in the opening of an existing house. It was.

  In addition, a simulation device that quantitatively evaluates the indoor thermal environment and energy-saving performance of air conditioning in a room, the indoor thermal environment due to differences in building use, area, window orientation, size, glass material, fence / blind, etc. Since the air-conditioning energy-saving performance is quantitatively evaluated, there is a problem in that it is not possible to evaluate the performance when an existing house is used and a heat insulating window is attached to the opening and the window is repaired.

  Furthermore, it has been desired to provide a system that enables a person who does not have specialized knowledge such as energy saving performance and window structure to easily evaluate the energy saving effect by a simple input operation.

  Furthermore, since the simulation evaluation using the model house and the house at the planning and design stage is less accurate than the simulation evaluation using the existing housing environment, improvement in accuracy has been desired.

The present invention was made in view of the above-described problems, and is an insulation performance diagnostic system for an opening that evaluates the insulation performance effect by installing an insulation window in the opening of an existing house, Area selection means for selecting an area classification corresponding to the area where the house to be repaired is present from the area information database, structure information, exterior wall information, roof information and opening information before the repair of the house, and power of the house Pre-renovation house information input means for inputting pre-renovation house information including the volume charge and CO ₂ emission basic unit, and the air conditioner COP (Coefficient Of Performance) of the house, the thickness of the air layer of the heat insulation window of the house, And post-renovation housing information input means for inputting renovation conditions including specifications of polycarbonate and glass windows, and post-renovation housing conditions including design room temperature after renovation, and before the renovation A calculation means for calculating heat insulation performance before and after refurbishment using home information, information on the house after renovation and information in the local information database, and diagnosing an energy saving effect by the heat insulation window by comparing the heat insulation performance before and after renovation, The problem is solved by having diagnostic display means for displaying the diagnosis result on a display unit, and storage means for storing the pre-renovation house information, the post-renovation house information, and the diagnosis result in a diagnosis result database for each house. .

  In addition, the regional information database has extended degree data for each regional section.

Furthermore, the heat insulation performance is characterized by comprising items of annual load, power consumption, power charge, and CO ₂ emission.

  Further, the diagnostic display means displays the diagnosis result values of the heat insulation performance before and after the renovation and the value of the energy saving effect of the heat insulation performance by installing the heat insulation window in a list, which is visually easy. It is characterized by being able to understand.

As described above, the thermal insulation performance diagnosis system for an opening according to the present invention includes an area selection means for selecting an area classification of a house to be repaired from a regional information database, and pre-renovation house information for inputting the pre-renovation house information of the house. Input means, renovation conditions for the heat insulation window of the house and post-renovation house information input means, calculation means for calculating the heat insulation performance before and after installing the heat insulation window in the house, By providing a diagnostic display means for diagnosing the heat insulation performance effect by the heat insulation window and displaying the diagnosis result, and a storage means for storing the home information before renovation, the home information after renovation and the diagnosis result in a diagnosis result database for each house, It is possible to diagnose the effects of the heat insulation performance of the annual load, the power consumption, the power charge, and the CO ₂ emission amount when the heat insulation window is attached to the opening of the existing house. This makes it possible to diagnose the heat insulation performance of non-newly built houses and collective homes that use single-layer glass in the opening, and attach a material with heat insulation effect to the single-layer glass. It is possible to diagnose the energy saving effect obtained by renovating to a double window and display the result.

  In addition, the regional information database can obtain the total amount of heat required for the heating (or cooling) period by having the extended degree data for each region. Thereby, since the climatic conditions of the area where the house exists can be reflected in the diagnosis of the heat insulation performance, a highly accurate diagnosis result can be obtained.

  Further, the diagnostic display means can easily visually understand the diagnosis result by displaying the value of the heat insulation performance before and after the repair and the value of the energy saving effect of the heat insulation performance by installing the heat insulation window in the list. As a result, the degree of improvement before and after the repair, which was difficult to be transmitted only by the calculation result of the calculation means, is displayed in comparison and can be easily recognized.

  Furthermore, by calculating the heat insulation performance with the calculation means based on the pre-renovation housing information and post-renovation housing information entered at the computer terminal, it is easy even for those who do not have expertise in energy saving performance, window structure, etc. It is possible to easily evaluate the energy saving effect through an input operation. As a result, until now we have been seeking specifications for heat insulation windows based on the experience of people such as window renovators and construction companies, but even those without this experience can easily determine the energy saving effect and specifications of heat insulation windows. Can do.

  Furthermore, by inputting the pre-renovation housing information of the house to be refurbished using the pre-renovation housing information input means, the diagnostic result value is more accurate than in the case of simulation evaluation using a model residence or a residence at the planning and design stage. Comes out. As a result, it is possible to improve the accuracy of the diagnosis result that could not be obtained by the conventional simulation apparatus.

  Initially, the structure of the opening part of a house is demonstrated easily using FIG. FIG. 1 is a cross-sectional view illustrating a state where a heat insulating window is installed in an opening of a house to be repaired.

  As shown in FIG. 1, the opening 40 is provided in the outer wall surface 41 of the house to be repaired, and the single-layer glass 42 is already used for the opening. A heat insulating window 43 formed of a material having a heat insulating effect is attached to the outside of the single layer glass 42 to constitute a double window. An air layer 44 (sealed dry air layer) is formed between the single-layer glass 42 and the heat insulating window 43, and the heat insulating performance varies depending on the thickness of the air layer. Although FIG. 1 shows the case where the heat insulating window 43 is installed outside the single layer glass 42, the heat insulating performance effect is obtained even when the heat insulating window 43 is installed inside the single layer glass 42. It is done.

  Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS.

  The opening thermal insulation performance diagnosis system of the present invention includes a computer terminal including an input unit, an output unit, a display unit, a storage unit, a calculation unit, and the like, and a database that stores regional information and information on diagnosis results of simulation evaluation. Consists of a system.

  FIG. 2 is a configuration diagram of an opening thermal insulation performance diagnosis system according to an embodiment of the present invention.

  As shown in FIG. 2, the opening thermal insulation performance diagnosis system includes at least a computer terminal 1, a regional information database 2, and a residential diagnosis result database 3.

  The computer terminal 1 is a terminal that can use the thermal insulation performance diagnosis system for the opening, and includes at least an input unit, an output unit, a display unit, a storage unit, a calculation unit, and a contractor who undertakes a window repair work, It is installed at stores that handle insulated windows. For example, the computer terminal 1 includes an area selection unit 11, a pre-renovation housing information input unit 12, a post-renovation housing information input unit 13, a calculation unit 14, a diagnosis display unit 15, and a storage unit 16. The area information, housing structure, repair conditions, and other data are input, and the diagnostic results evaluated by the simulation unit are displayed on the display unit.

  The area selection means 11 is a means for selecting an area classification corresponding to the area where the house to be repaired is present from the area information database 2, and the selected area classification is displayed on the display unit. For example, if the location of the house to be repaired (in this case, Osaka) is entered in the input section, it is selected from among the regional divisions managed in the regional information database (in this case, the 12 regional divisions A to L). Search and select the area corresponding to “Osaka Prefecture” (in this case, J area). The regional information database 2 will be described in detail later.

The housing information input means 12 before renovation includes structure information, exterior wall information, roof information, and opening information before renovation of the house, the electricity charge and CO ₂ emission basic unit of the house, and the air conditioner COP (Coefficient Of) of the house. It is a means to input the pre-renovation housing information including “Performance” at the input section. For example, enter the number of exterior walls and the number of roofs in the structure information, and enter the orientation, width, area, solar absorptivity, thickness and material of each layer of the walls or roof in the exterior wall information or roof information. In the opening information, the window specification, presence / absence of blinds, and window area are input. Enter the unit price before fuel cost adjustment by the fuel cost adjustment system for the electricity charge for the house, enter the value obtained by dividing the CO ₂ emission by the amount of electricity for the CO ₂ emission basic unit, and the air conditioner COP for the air conditioner Enter energy saving performance. COP is called “coefficient of performance” and indicates the ratio of the amount of heat and cold produced by an air conditioner to the amount of power consumed, and the higher the COP value, the better the energy efficiency. The COP calculation method is
COP = Cooling / Heating Capacity / Power Consumption For example, in the case of a heating COP of an air conditioner that obtains a heating capacity (heat) of 5.0 kW with power consumption of 1.0 kW,
Heating COP = 5.0kW / 1.0kW
= 5
It is.

  The post-renovation housing information input means 13 inputs the post-renovation home information including the thickness of the air layer when the heat insulation window is attached to the single-layer glass, the renovation conditions of the polycarbonate or glass window, and the design room temperature after the renovation at the input unit. Means. For example, the refurbishment conditions include a column for specifying the thickness of the air layer and a column for selecting the specification of the heat insulating window. The thickness of the air layer is a value that takes into consideration the thickness of the outer wall and the heat insulating effect (in this case, 6 mm). In the heat insulation window specification, a material having a heat insulation effect (in this case, polycarbonate) is selected from the polycarbonate or glass window list. Polycarbonate is a material that has not only sound insulation but also an effect as a heat insulating material. In addition, a room temperature to be maintained during cooling or heating at the design room temperature (in this case, 26 degrees during cooling and 22 degrees during heating) is input.

The calculating means 14 is a means for calculating the heat insulation performance before and after the renovation using the pre-renovation housing information, the renovated housing information, and the information in the regional information database 2. For example, the heat insulation performance is an annual load, power consumption, power charge, and CO ₂ emission, and the calculation means 14 calculates the values before and after the modification.

  Here, the extended degree day method when the calculation means 14 calculates the annual load will be described. FIG. 3A is a graph showing the heating degree day, and FIG. 3B is a graph showing the cooling degree day.

  (1) First, consider the thermal load q of a building at a certain time. Heat loss from the room during heating in winter can be ignored if the effects of solar radiation and effective radiation are ignored.

Is required.

  (2) Next, consider the daily heat load h. When the room temperature is constant throughout the day, the load at each time of the day changes according to changes in the outside air temperature. For example, the load at 1 o'clock

Is required.

  (4) Next, consider the winter heating degree day. Degree day (degree day) is the difference between the indoor reference temperature in the heating or cooling season and the average outside air temperature for a day.

の形で表示される。例えば、図３（Ａ）に示すごとく、暖房を開始する限界外気温度平均値（θ_om）を１６℃、暖房期の室内基準温度（θ_ｉ）を１８℃とした場合、デグリーデーＤ_{１８−１６}は、１日の平均外気温が１６℃を下回ると暖房を始め、室温を１８℃に保つ場合の暖房デグリーデーを表している。暖房デグリーデーとは、暖房期間に渡ってデグリーデーについて集計したものをいい、地域の気候によって値が変わり、寒いところの暖房デグリーデーは温暖地域より大きくなる。

Is displayed. For example, as shown in FIG. 3A, when the limit outside air temperature average value (θ _om ) at which heating is started is 16 ° C. and the indoor reference temperature (θ _i ) in the heating period is 18 ° C., Degree Day D _18-16 Represents a heating degree day when heating is started when the average outside temperature of the day falls below 16 ° C and the room temperature is kept at 18 ° C. The heating degree day is the sum of the degree days over the heating period. The value changes depending on the local climate, and the heating degree day in the cold place is larger than the warm area.

(5) Next, consider air conditioning degree days in summer. For example, FIG. 3 (B) is a graph showing cooling degree days when the limit outside air temperature average value (θ _om ) for starting cooling is 28 ° C. and the indoor reference temperature (θ _i ) in the cooling period is 26 ° C. is there. The cooling degree day is a total of the degree days over the cooling period, and is obtained in the same manner as the heating degree day. Detailed description is omitted here.

  (6) Finally, consider extended degree day. The above-mentioned degree day method considers only the influence of outside air temperature, and does not consider factors such as solar radiation and indoor heat generation. These effects were taken into account in the “Extended Degree Day” method, and when extended Degree Day is used, the heat load during the winter and summer periods is

It can be calculated by

  As described above, the calculation means 14 of the present invention obtains the heating and cooling loads in summer and winter using the extended degree day method in consideration of solar radiation, effective radiation, and heat generated in the room, and the window structure of the outer wall and opening before renovation. Based on this, the annual load before the repair is calculated, and then the annual load after the repair is calculated based on the window structure of the opening in the repair condition. Note that these calculated values are temporarily stored in the storage unit of the computer terminal 1 for use in the diagnostic display means 15.

  The diagnosis display means 15 is means for comparing the heat insulation performance before and after the repair calculated by the calculation means 14 to diagnose the energy saving effect by the heat insulation window and displaying the diagnosis result on the display unit. For example, the ratio of the degree of improvement is calculated by dividing the value before the improvement of each insulation performance calculated by the calculation means 14 by the value after the improvement, and the value of the improvement is calculated for each insulation performance before and after the improvement. Display side by side.

  The storage unit 16 stores the pre-renovation home information input by the pre-renovation home information input unit 13, the post-renovation home information input by the post-renovation home information input unit 14, and the diagnosis result displayed by the diagnosis display unit 15. It is a means of storing in the house-specific diagnosis result database 3 in association with each other. The diagnosis result database 3 for each house will be described later in detail.

  The regional information database 2 is a database that manages at least the extended degree data of the regional division. For example, the country created by the Foundation for Building Environment and Energy Conservation is divided into 12 regions (here, A to L regions), and regional information in consideration of the climate of each region is managed. In the case of region J, southern Mie Prefecture, Yoshino-gun, Nara Prefecture, Osaka Prefecture, Wakayama Prefecture, Awaji Island, Hyogo Prefecture, Kagawa Prefecture, Tokushima Prefecture, Kochi Prefecture, Ehime Prefecture, Fukuoka Prefecture, Saga Prefecture, Nagasaki Prefecture (the Tsushima branch office Oita Prefecture, Kumamoto Prefecture (excluding Amakusa Islands), and the regional information of Osaka Prefecture is displayed as the representative region of these regions.

  In addition, in order to deal with the finer climate differences than the 12 regions created by the Building Environment and Energy Conservation Organization, the extended degree day data for each prefecture may be created and managed in the regional information database 2 .

  The house-by-house diagnosis result database 3 is a database that manages house information before repair, house information after repair, and diagnosis results for each house. For example, the area classification of the area selection means 11, the housing information input means 12 before renovation and the housing information input means 13 after renovation, the diagnosis result of the diagnosis display means 15, and the like are managed.

This is a screen on which a part of post-housing information is input. For example, the first input screen 20 includes an area column 20a, a structure information column 20b, a design room temperature column 20c, and other columns 20d. The region column 20a is a column in which the region segment selected by the region selection means 11 (in this case, J region) is set, but the button on the right end of the region column is pressed to display a list of region segments, A desired region segment may be directly selected. The structure information column 20b is a column for inputting the number of outer walls and roofs of the house before renovation (in this case, the outer wall 4 and the roof 1), and the desired value is selected by pressing the button at the right end of each item. You can also. The design room temperature column 20c is a column for inputting the indoor reference temperature during cooling and heating of the house after renovation (in this case, 26 ° C. during cooling and 22 ° C. during heating). The other column 20d is a column for inputting the air conditioner COP installed in the house to be repaired, the electric energy charge, and the CO ₂ emission basic unit.

  After the input in each field is completed, the second input screen 30 is developed by pressing the OK button at the lower right of the screen. In addition, as shown in the figure, the input field of the pre-renovation house information may be represented by a straight line, and the input field of the post-renovation house information may be represented by a broken line so that the data content at the input location can be easily identified.

  As shown in FIG. 4 (B), the second input screen 30 is displayed by the region selection means 11, the pre-renovation housing information input means 12, or the post-renovation housing information input means 13, and the area classification, a part of the pre-renovation housing information, the renovation. This is a screen on which a part of post-housing information is input. For example, the second input screen 30 includes a tag for inputting information on an outer wall and a tag for inputting information on a roof, and the tag for inputting information on the outer wall includes a wall information column 30a, a window information column 30b before renovation, It consists of a wall structure column 30c and a window repair condition column 30d. The wall information column 30a is a column for inputting the outer wall information of the house before renovation, and the outer wall information is information on the azimuth, width, area, and solar radiation absorption rate. The window information column 30b before renovation is a column for inputting the specifications of the opening of the house before refurbishment (in this case, glass is 5 mm), the presence / absence of a blind, and the area. The wall structure column 30c is a column for inputting the outer wall of the house before renovation, and the thickness and material of each layer are input. The window modification condition column 30d is a column for inputting the thickness of the air layer and the material of the heat insulating window selected from the list of polycarbonate or glass windows. The roof information input tag includes a roof information column 31a for inputting a roof orientation, a roof area, and a solar radiation absorption rate, and a roof configuration column 31c for inputting the configuration of the roof of the house before renovation (see FIG. 9). .

  When the calculation button at the lower right of the screen is pressed after the input in each column is completed, the calculation means 14 starts calculating the heat insulation performance values before and after the modification.

  Next, FIG. 5 is an example of a screen displaying the diagnosis result of the opening thermal insulation performance diagnosis system according to the embodiment of the present invention.

As shown in FIG. 5, the diagnosis results are displayed in a list in order of the value before the repair, the value after the repair, and the value of the improvement degree by the repair for each item of the heat insulation performance. As a result, it is possible to easily grasp the annual energy saving effect in the items of heat insulation performance (in this case, annual load, power consumption, power charge, CO ₂ emission amount). It becomes easy to grasp at a glance the effect produced by the heat insulation modification to which the heat insulation window is attached. The list of diagnosis results may be expressed in a shape that is easy to understand visually, such as a line graph or a bar graph.

  If you want to redo the simulation by changing the renovation condition of the heat insulation window or the design room temperature of the refurbished house, if you press the calculation start button on the upper right of the screen, the first input screen 20 is developed and the house The process returns to the information input screen.
