  Next, simulations performed using the various data and various means will be described using examples.

<First simulation example: Building opening design simulation for builders>
First, “building opening design simulation for builders” will be described as a first simulation example. The purpose of this simulation is to provide information to the builder.

  For example, while simulating indoor airflow (path, air volume) based on the layout of the specified opening device, and comparing each simulation result, the comparison result is evaluated, and the builder supports the design. Is to do. In the evaluation, by using the comfort index, the simulation result is more easily understood by the builder and is effectively used.

  The first simulation is not only provided to the builder by the housing equipment manufacturer using the client system 10 (FIG. 1), but also to the client system 10 (see FIG. 1) on the builder side information terminal (such as a personal computer or a mobile phone). It is conceivable that the same operation as in the case of using 1) is performed by the builder itself.

In the first simulation example described below, what is shown in the following figures is output.

First, in the client system 10, a condition setting screen is displayed on the display 12, and various conditions are set (step S01) using the keyboard 14 or the like.

  The various conditions set here may be selected based on the various data 101 to 113, or may be appropriately input and additionally registered in the various data. For example, in the case of simulating a floor plan or layout arrangement of an opening device for a building, it is possible to make a selection from the layout or layout of the opening device already registered in the design data 101, or to add a new design. It may be input.

  In addition, for example, while setting a specific period and time zone, it is set to refer to weather data corresponding to the set period and time zone, or while setting a specific period and time zone, It is good also as setting weather conditions (outdoor environment) arbitrarily (for example, the presence or absence of a wind). In addition, conditions may be set from the above-described scenes. For example, it is possible to perform settings such as performing simulation only for the scene 6A shown in Table 1 or executing simulation for all scenes.

  Also, an output form of simulation is set. In this simulation for the purpose of providing information to the builder, various output formats shown in FIGS. 5 to 10 are set.

  Further, in the condition setting in step S01, a design to be compared is set in order to evaluate the superiority by the current condition setting. In other words, for example, when a so-called “specified plan” (basic design) is to be compared, various conditions corresponding to the “specified plan” are set, or various conditions corresponding to the plan that has been studied in the past by simulation. A condition is set (designation of attribute information described above).

  Next, the various conditions set in step S01 are recognized by the simulation condition recognition unit 143 (step S02). As a result, conditions necessary for the simulation (building, floor plan, elevation, opening device arrangement, opening / closing state of the opening device, scene, etc.) are recognized by the client system 10, and a specific building is specified. It becomes a state in which a simulation of airflow and comfort in the building room during the period and time zone can be executed.

  Next, the simulation executing means 140 performs a simulation of the airflow (ventilation) when there is an outdoor wind shown in FIG. 6 based on the various conditions set in step S01 (step S04).

  Specifically, an arrow-shaped airflow K1, K2,... Is calculated with respect to the set floor plan by a well-known simulation technique, and processing for enabling display on the floor plan is performed. The airflows K1 and K2 are calculated based on the set floor plan and elevation, the arrangement and opening / closing state of the opening device, the outdoor weather conditions, and the like. The design data 101, the opening device Data 102, period data 104, geographic data 108, and weather data 151 are referred to as appropriate. In this simulation, it is set as a condition that there is an outdoor wind (wind flow). Note that the calculation processing method in the simulation is not particularly limited (the same applies to the simulation described below).

  Next, the simulation execution means 140 performs a simulation of the airflow (temperature difference ventilation) when there is no outdoor outdoor air as shown in FIG. 7 based on the various conditions set in step S01 (step S05).

  Specifically, an arrow-shaped airflow K1, K2,... Is calculated with respect to the set floor plan by a well-known simulation technique, and processing for enabling display on the floor plan is performed. The airflows K1 and K2 are calculated based on the set floor plan and elevation, the arrangement and opening / closing state of the opening device, the outdoor weather conditions, and the like. The design data 101, the opening device Data 102, period data 104, geographic data 108, and weather data 151 are referred to as appropriate. In this simulation, it is set as a condition that there is no outdoor wind especially in the daytime period (for example, 11:00 to 19:00).

  Next, the simulation execution means 140 performs a simulation of the airflow (temperature difference ventilation) when there is no outdoor wind at bedtime shown in FIG. 8 based on the various conditions set in step S01 (step S06).

  Specifically, an arrow-shaped airflow K1, K2,... Is calculated with respect to the set floor plan by a well-known simulation technique, and processing for enabling display on the floor plan is performed. The airflows K1 and K2 are calculated based on the set floor plan and elevation, the arrangement and opening / closing state of the opening device, the outdoor weather conditions, and the like. The design data 101, the opening device Data 102, period data 104, geographic data 108, and weather data 151 are referred to as appropriate. Further, in this simulation, it is set as a condition that there is no outdoor wind especially during a bedtime (for example, from 23:00 to 7:00).

  Next, the simulation execution means 140 performs a process for creating the proposed plan shown in FIG. 9 based on the various conditions set in step S01 (step S07).

  Specifically, processing is performed to enable the selected opening device to be displayed in the north elevation, the south elevation, the west elevation, and the east elevation. This display is calculated based on the set elevation, the arrangement of the opening device, and the like, and the design data 101 and the opening device data 102 are appropriately referred to.

  Next, the simulation executing means 140 performs processing for creating the comparison display sheet shown in FIG. 10 based on the various conditions set in step S01 (step S08).

  Specifically, the comfort determination means 134 obtains the comfort index corresponding to the various conditions set in step S01 by calculation, and the calculation result can be displayed in the “suggested plan display area H2” in the comparison display sheet. Process to do.

  In this embodiment, the comfort index according to the PMV shown in FIG. 3 is obtained, and the numerical value of PMV (−3 to +3) is obtained by calculation. The calculation of the numerical value of PMV is performed by referring to various conditions set in step S01 and the airflow information simulated in steps S04, S05, and S06, and is calculated by a known technique. Can do. A specific calculation processing method is not particularly limited.

  Further, in this embodiment, as shown in FIG. 10, the PMV values are as follows. When there is an outdoor wind, when there is no outdoor wind, each period (June, July...) And each time zone in each case. The face icons 207a, 207b, and 207c that are obtained for each scene defined by the combination of elements (morning, noon, night, and bedtime) and that correspond to the numerical values are displayed on the comparison display sheet. In addition, when the outside air temperature is equal to or higher than a predetermined temperature, an “air conditioner” icon 207e is displayed.

  In addition, the simulation execution unit 140 sets the comfort index when the condition corresponding to the specified design is set in the “current plan display area H1” in the comparison display sheet shown in FIG. The evaluation result of the comfort index performed before the number of times (past simulation)) is in a state in which it can be compared and displayed.

  Specifically, the process for acquiring the comparison target data 112 by the comparison target data acquisition unit 132 and displaying the evaluation result of the comfort index corresponding to the acquired condition setting in the “current plan display area H1”. I do.

  Further, the simulation execution means 140 stores the current simulation condition setting in the comparison target data 112 for use as a comparison target in subsequent simulations (step S09).

  Thereby, in the simulation after the next time, the condition setting of this simulation can be acquired. As described above, the combination of condition settings for each simulation is stored in the comparison target data 112 together with the attribute information (ID number and the like). In later simulations, the combination of the condition settings is specified by the attribute information. Acquired in a batch. In addition, the comparison target data 112 stores information on the calculation result of the comfort index and the calculation result of the simulation together with the attribute information, so that the calculation time in step S08 can be shortened, for example.

  In addition, the simulation is performed by the simulation execution unit 140 as described above, and the simulation result can be displayed on the display 12 by the simulation result output unit 141 or printed out from the printer 15 (step S10).

  Various outputs shown in FIGS. 5 to 10 can be obtained by the series of processes (steps S01 to S10). By repeating this series of processing arbitrarily, that is, by performing a simulation by setting various conditions and comparing the output, it is possible to select an optimum condition setting.

  Further, each output shown in FIG. 5 to FIG. 10 will be described. In the “architectural feature sheet” shown in FIG. 5, an aerial photograph (map) 209a, a layout diagram 209b, and a wind map 209d are displayed. The builder can visually understand the characteristics of the building, and can examine and evaluate based on numerical values. Note that the explanatory text 209e can be displayed by arbitrary input by the operator, or can be automatically displayed by comparing text stored in advance in the storage device with weather data.

  Further, in the simulation results shown in FIGS. 6 to 8, the airflows K1, K2,... Flowing through the room are displayed on the floor plan, so that the builder can visually understand the characteristics of the airflow flowing through the room. It becomes possible. Further, it is conceivable that the explanation of the consideration sentence 261 and the proposal sentence 262 shown in FIG. 6 can be displayed by arbitrary input by the operator. It is also conceivable that the icon 263 of the opening device actually arranged can be displayed arbitrarily.

  Here, FIG. 6 is a simulation of the airflow when there is an outdoor wind, FIG. 7 is when there is no outdoor wind during the day, and FIG. 8 is a simulation when there is an outdoor wind when there is no outdoor wind at bedtime. For each scene defined by the combination of elements in each period (June, July ...) and each time zone (morning, noon, night, bedtime) in the absence of outdoor wind Will be able to study and evaluate airflow.

In the above embodiment, simulation is performed in each of “when there is an outdoor wind (FIG. 6)” and “when there is no outdoor wind (FIGS. 7 and 8)”.
First, when “there is an outdoor wind (FIG. 6)”, the simulation can be performed from the viewpoint of “ventilating and collecting air effectively using the outdoor wind” such as “ventilating the outdoor wind through the room”. . Then, in order to make it easier for the builder to understand the viewpoint such as ventilation, a suggestion sentence 262 (“the ventilation effect is enhanced by changing to a wind sampling model”) along the principle of improving comfort is displayed.

  The explanatory text 262 may be in any form, such as being automatically displayed and set in the calculation process of step S04, or appropriately input by the operator. Also, the ventilation keyword V6 is automatically displayed and set in the calculation process of step S04 in the output format shown in FIG. 6, or stored in advance in the format data of FIG. 6, or appropriately by the operator. By inputting the information, the builder can be surely grasped that the comfort is improved by the concept of ventilation.

  On the other hand, when “there is no outdoor wind (FIGS. 7 and 8)”, the simulation can be performed from the viewpoint of “temperature difference ventilation” such as “ventilating by making use of the height difference of the opening position”. Further, in the simulation shown in FIG. 7, since it is a daytime time zone, basically a simulation for improving comfort by effectively opening the opening device on each floor is performed. On the other hand, in the simulation shown in FIG. 8, since it is a night time zone, taking into account the prevention of crime prevention and quietness, the improvement of comfort by the effective opening of the opening device of the room (bedroom) on the second floor or loft floor. A simulation is performed.

  In order to make it easier for the builder to understand the viewpoint of this temperature difference ventilation, in FIG. 7, the explanation 264A of the principle of improving comfort (“air on the first floor passes through the vent (staircase) to the second floor”. ")", Explanatory document 264B ("Two air passes through the vent (staircase) and goes up to the loft floor") is displayed. Further, in FIG. 8, a proposal 264C (“Temperature differential ventilation is possible at bedtime by installing a waist window / ground window”) is displayed in accordance with the principle of improving comfort. In addition, in order to clarify the viewpoint of temperature difference ventilation, the flow direction icons 207g (to the second floor), 207h (from the first floor), 207j (to the loft floor), 207k (from the second floor) are on the floor plan. Is displayed.

  The explanatory texts 264A and 264B, the proposal text 246C, and the flow direction icon are automatically displayed and set in the calculation processing of steps S05 and S06, respectively, or stored in advance in the format data of FIGS. Or may be input as appropriate by the operator. In addition, in the output formats shown in FIGS. 7 and 8, the temperature difference ventilation keywords V7 and V8 are automatically displayed and set in the calculation processing of steps S05 and S06, or the data in the formats of FIGS. In advance, the builder can be surely grasped that the comfort is improved by the concept of temperature difference ventilation.

  In the “proposed plan” shown in FIG. 9, the builder can visually understand the arrangement of the opening device in the north elevation, the south elevation, the west elevation, and the east elevation, and Therefore, it will be possible to examine and evaluate the arrangement. In addition, in this “suggestion plan”, it is conceivable to arrange a proposal 291 about the arrangement and installation of the opening device, an icon 263 of the opening device actually arranged, and the like. May be in any form, such as being automatically displayed and set in the calculation process of step S07, or stored in advance in data in the format of FIG. 9, or appropriately input by the operator.

  Further, in the “contrast display sheet” shown in FIG. 10, in the “current plan display area H1” and the “suggested plan display area H2,” the comfort index for each combination of period and time zone is the face icon 207a / 207b.・ Displayed by 207c. Thereby, the builder can visually understand the comfort of each plan (condition setting set in step S01 described above), and can examine and evaluate the arrangement. In particular, by using a face icon that expresses a human expression, it is possible to instantly image a comfortable range, an allowable range, and an outside of the allowable range.

  In the “contrast display sheet” shown in FIG. 10, in the “current plan display area H1” and the “proposed plan display area H2,” the period (month, time, season, etc.) is shown in the vertical column, and the time zone ( (Morning, noon, night, bedtime, etc.) are displayed in a matrix (table format) that can be displayed as items, and a comfort index is displayed in each item. FIG. 11 is a partially enlarged view of the “contrast display sheet”.

  By displaying in the matrix in this way, it becomes possible to display the comfort index for each scene in the period and time zone in an easily understandable manner. The display relationship between the vertical column and the horizontal column may be reversed.

  Further, in the “contrast display sheet” shown in FIG. 10, the “current plan display area H1” and the “proposed plan display area H2” are displayed in a vertical contrast, so that “which plan is more comfortable?” This can be compared.

  For example, in the morning time zone when there is a wind in the example of FIG. 10, the face icon 207c indicating “out of range” is displayed in the current plan display area H1 except for the end of July and the beginning of August. However, in the proposed plan display area H2, it is either “comfortable range” or “acceptable range”, and it can be easily confirmed that a more comfortable environment can be obtained in the proposed plan. Further, since the comfort index conforms to the ISO standard PMV, the objectivity is ensured in the evaluation, so that the builder can be used as highly reliable information.

  Further, in the “contrast display sheet” shown in FIG. 10, simulation of ventilation when there is wind and simulation of temperature difference ventilation when there is no wind are displayed in parallel. (Scene) can be viewed at a time. By displaying in parallel in this way, ventilation and temperature difference ventilation can be compared, and simulation can be evaluated in consideration of the difference in the situation (scene). Of course, simulation results of ventilation and temperature difference ventilation may be displayed on individual sheets.

  Further, in the “contrast display sheet” shown in FIG. 10, in addition to the face icon, the display of the average temperature in each scene is written together, and it is possible to refer to this average temperature. If the outside air temperature is too high and the user is not comfortable even if outside air is taken in, the “air conditioner” icon 207e is displayed instead of the face icon. Thereby, the builder can examine and evaluate that “the air conditioning by the air conditioner is necessary in a certain scene”.

  In FIG. 10, the simulation result under a specific condition is displayed as previous information (“Before” / “current plan”) in the “current plan display area H1”, and is displayed separately in the “suggested plan display area H2”. As a simulation result based on the above condition, change information (“After” / “Proposed plan”) is displayed.

  As a result, it is possible to show how to be conscious of Before / After, that is, how to show before and after the examination, and the builder can perform an easy-to-understand evaluation.

  Further, the way of showing the “Before / After” may be applied to the display of each simulation result shown in FIGS. 6 to 8 in addition to the comparison display sheet of FIG. That is, for example, in FIG. 6, the air current K1, K2,... In the case of the “current plan” is displayed in red as “Before”, and the airflow K1, K2,. It can be considered that the difference between the airflows K1, K2,...

<Second simulation example: Ventilation simulation for residents>
Next, “residential ventilation simulation” will be described as a second simulation example. The purpose of this simulation is to provide the occupants with the ventilation conditions that are realized when they actually live.

  For example, providing the resident with what ventilation is provided and how comfortable is expected (expected) when the opening device is opened in the plan proposed by the builder It is. Thereby, in the resident, while being able to imagine the state of ventilation before living, it can be used as a guide for the ventilation method after living.

  This second simulation is not only provided to the resident by the housing equipment manufacturer or builder using the client system 10 (FIG. 1), but also the client system in the resident side information terminal (such as a personal computer or a mobile phone). It is conceivable that the same operation as in the case of using 10 (FIG. 1) is performed by the resident himself.

  Further, the operations of steps M01 to M05 described below and the calculation of the comfort index in step M06 are the same as the processes performed in steps S01, S2, S4 to S6, S08 in the first simulation example described above. It is. For this reason, for example, in the case where the first simulation and the second simulation are performed simultaneously, in the second simulation, by obtaining the calculation result of the first simulation, the comfort index and the simulation recalculation time are obtained. May be shortened or omitted. Conversely, in the first simulation, the calculation result of the second simulation may be acquired.

In the second simulation example described below, what is shown in the following figures is output.
・ Simulation of the airflow (ventilation) when there is an outdoor wind shown in FIG. 13 ・ Simulation of the airflow (temperature difference ventilation) when there is no outdoor air as shown in FIG. 14 ・ Outdoor at the time of sleep shown in FIG.

An example of the simulation will be described with reference to the flowchart shown in FIG. In addition, please refer FIG.1 and FIG.4 suitably for the code | symbol of the term used below.
First, in the client system 10, a condition setting screen is displayed on the display 12, and various conditions are set (step M01) using the keyboard 14 or the like.

  The various conditions set here may be selected based on various data 101 to 112, or may be appropriately input and additionally registered in various data. For example, when simulating a floor plan or layout arrangement of an opening device for a building, the floor plan already registered in the design data 101 can be selected from the layout of the opening device, or a new design can be added. It may be input.

  In addition, for example, a specific period and time zone are set and the weather data corresponding to the set period and time zone is referred to, or a specific weather is set while setting the specific period and time zone. It is good also as setting a situation (outdoor environment) arbitrarily (for example, the presence or absence of a wind). In addition, conditions may be set from the above-described scenes. For example, it is possible to perform settings such as performing simulation only for the scene 6A shown in Table 1 or executing simulation for all scenes.

  Also, an output form of simulation is set. In this simulation for the purpose of providing information to the resident, various output formats shown in FIGS. 13 to 15 are set.

  Further, in the condition setting in step M01, various settings set in the “building opening design simulation for builders” which is the first simulation described above may be set. That is, for example, the attribute information (ID number or the like) described above is designated.

  Next, the various conditions set in step M01 are recognized by the simulation condition recognition unit 143 (step M02). As a result, the conditions necessary for the simulation (building, floor plan, elevation, opening device arrangement, opening / closing state of opening device, period, etc.) are recognized by the client system 10, and a specific building is specified. It becomes a state in which a simulation of airflow and comfort in the building room during the period and time zone can be executed.

  Next, the simulation execution means 140 performs a simulation of the airflow (ventilation) when there is an outdoor wind shown in FIG. 13 based on the various conditions set in step M01 (step M03).

  Specifically, an arrow-shaped airflow K1, K2,... Is calculated with respect to the set floor plan by a well-known simulation technique, and processing for enabling display on the floor plan is performed. Further, in order to express the open / closed state of the opening device in an easily understandable manner, a process for enabling the opening icon (with outdoor wind) 207x to be displayed near the portion of the opening device to be opened is performed.

  The airflows K1 and K2 are calculated based on the set floor plan and elevation, the arrangement and opening / closing state of the opening device, the outdoor weather conditions, and the like. The design data 101, the opening device Data 102, period data 104, geographic data 108, weather data 151, icon data 107, and the like are referred to as appropriate. In this simulation, it is set as a condition that there is an outdoor wind (wind flow).

  Next, the simulation execution means 140 performs a simulation of the airflow (temperature difference ventilation) when there is no outdoor outdoor air as shown in FIG. 14 based on the various conditions set in step M01 (step M04).

  Specifically, an arrow-shaped airflow K1, K2,... Is calculated with respect to the set floor plan by a well-known simulation technique, and processing for enabling display on the floor plan is performed. Further, in order to express the open / closed state of the opening device in an easily understandable manner, a process for enabling an open icon (no outdoor wind (daytime)) 207y to be displayed near the portion of the opening device to be opened is performed.

  The airflows K1 and K2 are calculated based on the set floor plan and elevation, the arrangement and opening / closing state of the opening device, the outdoor weather conditions, and the like. The design data 101, the opening device Data 102, period data 104, geographic data 108, weather data 151, icon data 107, and the like are referred to as appropriate. In this simulation, it is set as a condition that there is no outdoor wind especially in the daytime period (for example, 11:00 to 19:00).

  Next, based on the various conditions set in step M01, the simulation execution means 140 performs a simulation of the airflow (temperature difference ventilation) when there is no outdoor wind at bedtime shown in FIG. 15 (step M05).

  Specifically, an arrow-shaped airflow K1, K2,... Is calculated with respect to the set floor plan by a well-known simulation technique, and processing for enabling display on the floor plan is performed. Further, in order to express the open / closed state of the opening device in an easy-to-understand manner, a process for enabling an open icon (no outdoor wind (at bedtime)) 207z to be displayed near the portion of the opening device to be opened is performed. .

  The airflows K1 and K2 are calculated based on the set floor plan and elevation, the arrangement and opening / closing state of the opening device, the outdoor weather conditions, and the like. The design data 101, the opening device Data 102, period data 104, geographic data 108, weather data 151, icon data 107, and the like are referred to as appropriate. Further, in this simulation, it is set as a condition that there is no outdoor wind especially during a bedtime (for example, from 23:00 to 7:00).

  Next, the simulation execution means 140 performs processing for enabling the display of the opening / closing guideline table N shown in FIGS. 13 to 15 based on the various conditions set in step M01 (step M06).

  Specifically, the comfort determination means 134 obtains a comfort index corresponding to the various conditions set in step M01 by calculation, and enables an icon based on the calculation result to be displayed on the open / close guide table N. Process. This open / close indication table N includes a matrix that can display the period in the vertical column and the time zone in the horizontal column as items, and the open / close setting of the opening device is displayed in each item. Yes. The items in the vertical column and the horizontal column may be reversed.

  In this embodiment, the comfort index according to the PMV shown in FIG. 3 is obtained, and the numerical value of PMV (−3 to +3) is obtained by calculation. The calculation of the numerical value of PMV is performed with reference to various conditions set in step M01 and information on airflows simulated in steps M03, M04, and M05. Is not particularly limited.

  Further, in this embodiment, the PMV values are as follows: when there is an outdoor wind, when there is no outdoor wind, each period (June, July ...) and each time zone (morning, noon, night) For each scene defined by a combination of elements.

  And, for the scene where the PMV value is within the range of −1 to +1, the comfort determination unit 134 can expect to improve the comfort of the airflow by opening the opening device, In the example of FIG. 13, it is determined that the open icon (with outdoor wind) 207x is displayed in the open / close guide table N.

  On the other hand, when the outside air temperature is equal to or higher than the predetermined temperature, it is determined that the “air conditioner” icon 207e is displayed in the open / close guide table N. In this way, the open icon (with outdoor wind) 207x and the “air conditioner” icon 207e can be displayed in each scene of the open / close guide table N.

  Further, the simulation is performed by the simulation execution unit 140 as described above, and the simulation result can be displayed on the display 12 by the simulation result output unit 141 or printed out from the printer 15 (step M07).

  Various outputs shown in FIGS. 13 to 15 can be obtained by the series of processes (steps M01 to M07). By repeating this series of processing arbitrarily, that is, by performing a simulation by setting various conditions and comparing the output, it is possible to select an optimum condition setting.

  In the simulation results shown in FIG. 13 to FIG. 15, the airflows K1, K2,... Flowing through the room are displayed on the floor plan. It becomes understandable. The explanatory texts 265 and 266 shown in FIG. 13 are automatically displayed and set in the calculation process of step M03, or stored in advance in the format data of FIG. 13, or appropriately input by the operator. Any form may be used.

  Further, FIG. 13 shows the simulation of the air flow when a specific opening device is opened when there is an outdoor wind, FIG. 14 shows no daytime outdoor wind, and FIG. 15 shows no outdoor wind at bedtime. If there is outdoor wind, there is no outdoor wind, each period (June, July ...), each time zone (morning, noon, night, bedtime) in each case For each scene defined by the combination, the resident can imagine the flow of the airflow and how to open the opening device. Specifically, the open / close setting in each scene can be easily grasped by referring to the open / close guide table N.

  For example, as shown in FIG. 13, an open icon (with outdoor wind) 207x is displayed in a scene having a combination of outdoor wind, period = June, time zone = morning, and in this scene, It can be grasped that the effect of improving the comfort can be expected by opening the opening device. Similarly, an “air conditioner” icon 207e is displayed in a scene consisting of a combination of period = early August and time period = morning, and in this scene, the effect can be expected even if the opening device is opened. It can be understood that air conditioning using an air conditioner is necessary.

In the above embodiment, the simulation is performed in each of “when there is an outdoor wind (FIG. 13)” and “when there is no outdoor wind (FIGS. 14 and 15)”.
First, when “there is outdoor wind (FIG. 13)”, it is possible to perform simulation from the viewpoint of “ventilation and wind taking advantage of outdoor wind” such as “ventilate the outdoor wind through the room”. .

  In order to make it easier for residents to understand this aspect of ventilation, the explanation 267 of the principle of improving comfort (“What is ventilation? ... The wind passes through. ”) Is displayed. The explanatory text 267 is automatically displayed and set in the calculation process of step M03, stored in advance in the format data of FIG. 13, or appropriately input by the operator. It may be.

  On the other hand, when “there is no outdoor wind (FIGS. 14 and 15)”, the simulation can be performed from the viewpoint of “temperature difference ventilation” such as “ventilating by making use of the height difference of the opening position”. Further, in the simulation shown in FIG. 14, since it is the daytime time zone, basically, a simulation for improving comfort by effectively opening the opening device on each floor is performed.

  In addition, in the simulation shown in FIG. 15, since it is a night time zone, taking into account the prevention of crime prevention and quietness, it is possible to improve comfort by effectively opening the opening device of the room (bedroom) on the second floor or loft floor. A simulation is performed.

  In order to make it easier for residents to understand this viewpoint of temperature difference ventilation, in FIG. 14, explanation 268 of the principle for improving comfort (“What is temperature difference ventilation? ... warm air rises upwards. This is a ventilation method that uses the nature. It can be ventilated even when the wind is not blowing. ”) Is displayed, and in FIG. 15, the explanation 269 of the principle that improves comfort (“ What is temperature difference ventilation?・ This is a ventilation method using the property that warm air rises up. Ventilation can be performed with the indoor door closed. ”) Is displayed.

  Moreover, as shown in FIG. 14, in order to clarify the viewpoint of temperature difference ventilation, flow direction icons 207g (to the second floor), 207h (from the first floor), 207j (to the loft floor), 207k (from the second floor) ) Is displayed on the floor plan. The explanatory texts 268 and 269 and the flow direction icons are automatically displayed and set in the arithmetic processing of steps M04 and M05, or stored in advance in the format data of FIGS. Any form may be employed such as an appropriate input by the operator.

  Moreover, the simulation results shown in FIGS. 13 to 15 can be provided to a resident as a guide for a ventilation method after residence. And in a resident, after residence, the improvement of comfort can be aimed at by referring to the simulation result of each figure and setting opening and closing of an opening device according to each scene. In addition to providing the simulation result to the resident before residence, the simulation result may also be provided after residence, or to be viewable online on a personal computer or mobile phone owned by the resident.

  Also, it should be noted here that the concept of “scene” is to be able to grasp the opening / closing setting of the opening device and a measure of comfort. That is, conventionally, there has been a technique for providing information such as “a specific opening device opening / closing setting for a specific date and time”, but the concept of providing information such as “opening device opening / closing setting according to a scene” It did not exist.

  For example, assuming the use of simulation in the prior art, the resident needs to make the system recognize the specific date and time to be simulated, and the opening setting of each opening device corresponding to the setting of the date and time Was obtained. In this case, there is a concern that it is troublesome to specify the date and time, and that a detailed opening setting instruction gives a troublesome impression to the resident.

  On the other hand, assuming the use of the simulation of the present embodiment, the resident refers to the icon of the corresponding scene from the opening / closing guideline table N, and determines whether or not the comfort can be improved by opening the opening device. I can grasp it. That is, when an open icon (207x (FIG. 13) or the like) is displayed, it can be expected to ensure comfort by opening the opening device, while when an air conditioner icon 207e is displayed. Therefore, it can be understood that it is difficult to ensure comfort by opening the opening device.

  Thereby, first, it can be set as the condition where a resident can judge easily whether it opens or not. For example, it can be expected that an intention to “open and take in the outside air because the open icon is displayed!” Will be born.

  In addition, since the explanation 267 (FIG. 13) and the like are displayed, the resident can understand that the effect of opening can be expected, so the resident can expect to open the opening device positively. That is, it can be expected that the resident performs “aggressive opening and closing work”.

  Furthermore, if the intent of “aggressive opening and closing work” is born by the resident, it is expected that the resident will open based on the opening icon (207x (FIG. 13), etc.) displayed on the floor plan. This is not a matter of course, but the arrangement of windows optimally designed by simulation can be used effectively, and the simulation can be effectively used for residents.

  The simulation according to the present invention can be widely used as a tool for evaluating comfort based on ventilation and temperature difference ventilation of a building. Moreover, it becomes possible to provide the building which can implement | achieve evaluation of the simulated comfort by utilizing a simulation.
