And this drive control part is connected to the control part 22 via the said communication part 28, from the ventilation path selection apparatus 21 regardless of the drive control according to the operation | movement of the control part 22, and the operation | movement of the control part 22. It is set so that independent drive control is possible. In other words, ON / OFF switching of the ceiling fan 34, switching of driving strength, and the like can be independently controlled even from the ventilation path selection device 21.

Although not shown, the ventilation fan 35 is provided in each room such as the kitchen 10, the toilets 4 and 12, and the bathroom, and is attached to a ventilation hole formed in the wall or ceiling of the room. Other rooms may be provided as appropriate.
The ventilation fan 35 also includes a drive control unit that controls its own rotational drive, like the ceiling fan. And it is connected to the control part 22 via the said communication part 28, The drive control according to operation | movement of the control part 22, and the drive control independent of the ventilation path | route selection apparatus 21 irrespective of the operation | movement of the control part 22 are carried out. It is set to be possible. That is, ON / OFF switching of the ventilation fan 35 and switching of driving strength can be controlled independently from the ventilation path selection device 21.

Although not shown, the air conditioners 36 are arranged at a plurality of locations inside the building 1.
In this embodiment, for example, an air conditioner 36 is provided in each room formed so as to be separable from other rooms by a door, such as the first-floor bedroom 3, the second-floor bedroom 13, and the child rooms 15 and 16. It has been. Further, it is assumed that an appropriate number of spaces are provided in an integrated space such as a shared living space including the living room 7 and the like.
The air conditioner 36 also has its own control unit, and is connected to the control unit 22 via the communication unit 28. Therefore, the control according to the operation of the control unit 22 and the control independent of the ventilation path selection device 21 regardless of the operation of the control unit 22 are set. That is, ON / OFF switching of the air conditioner 36, switching of operation modes (cooling, heating, dehumidification, etc.), adjustment of the air volume, adjustment of the wind direction, etc. can be controlled independently from the ventilation path selection device 21. Yes.

The ventilation path selecting system 20 is constituted by the skylight and ceiling fan 34, the ventilation fan 35, the air conditioner 36, and a control device (not shown) for controlling the ceiling fan 34, the ventilation fan 35 and the air conditioner 36. Different ventilation systems can be operated.
In other words, this ventilation system uses the property that warm air rises, and is configured to take in natural wind while removing the hot air remaining in the vicinity of the ceiling of the room by the operation of the ceiling fan 34 and the ventilation fan 35. In addition, by operating the air conditioner 36 in an auxiliary manner, the operation time of the ventilation system itself can be reduced.
The control device for such a ventilation system is connected to the control unit 22 of the ventilation path selection device 21, and the ventilation path selection device regardless of the control according to the operation of the control unit 22 and the operation of the control unit 22. 21 is set so that the control can be performed independently of the control 21. That is, the ventilation system can be operated independently, and can be operated in conjunction with the ventilation path selection device 21.

The shutter device 37 enables ventilation while blocking intrusion of people through an opening such as a window or a line of sight from the outside. As shown in FIG. 2 and FIG. Is provided on the outer wall of the building 1 in which the opening 3a is formed.
The shutter device 37 includes a shutter curtain having a plurality of slats and a ventilation portion formed between the slats and other slats as the slats rotate. Moreover, this shutter curtain is slidably and firmly attached to the guide rail fixed to the outer wall, and is excellent in crime prevention.
The shutter device 37 also has a unique control unit, and is connected to the control unit 22 via the communication unit 28. Therefore, the control according to the operation of the control unit 22 and the control independent of the ventilation path selection device 21 regardless of the operation of the control unit 22 are set. In other words, the shutter curtain winding / unwinding operation, the slat rotating operation, and the like can be controlled independently from the ventilation path selection device 21.

Next, a ventilation route selection method using the above-described ventilation route selection system, and a building ventilation method including this ventilation route selection method will be described.
First, data 27b of internal information of the building 1 is stored in the data storage unit 27 of the storage unit 25.
The building internal information data 27b includes basic data including information such as the arrangement of the room inside the building 1, the position of the opening, and the room allocation of the resident, the location of the ventilation target set by the resident, and the ventilation non-target And additional data including information such as the location to be leeward.

  Of the basic data, the information on the layout of the rooms and the position of the openings are not easily changed after completion of the building except during renovation, so it may be set by the resident or set in advance by the contractor. May be. The room layout is also considered by the residents once, and it is difficult to change greatly after the room layout. Therefore, information such as the arrangement of the rooms is stored in advance as basic data.

The place to be ventilated in the additional data refers to a place where wind is taken into the building 1 and ventilation is particularly desired by this wind.
Further, the non-ventilated place refers to a place where the wind is not allowed to pass when the wind is taken into the building 1.
Moreover, the place which should be leeward refers to the place which does not want to be on the wind path on the ventilation path when taking in the inside of the building 1.

Of the additional data non-ventilated location and the location to be leeward, preset locations are set in advance.
That is, examples of the place that should be set in the leeward in advance include a room that cannot change the arrangement of the room and emits an odor, such as the toilets 4 and 12 and the kitchen 10. The room that emits this odor may be a non-ventilated place that does not allow the passage of wind.
When both the toilets 4 and 12 and the kitchen 10 are on the selected ventilation path, the toilets 4 and 12 are made leeward rather than the kitchen 10.
Since the toilets 4 and 12 and the kitchen 10 are not rooms in which the arrangement location in the building 1 can be easily changed, they are additional data set by a resident, but are close to the nature of the basic data. Yes.
Moreover, the room which emits this odor is set also in the place where ventilation is not intended and the place where it should be leeward when the resident is absent.

  In addition, a bathroom is an example of a place that should be leeward where the room layout cannot be changed. That is, if the bathroom is winded up in the high humidity season such as in the summer season or the rainy season, the humid air spreads inside the building 1 and it may be difficult to form a comfortable living environment. On the contrary, in the season when the air is dry like winter, the bathroom may be set upwind on the ventilation path. Especially when the bathroom is set up on the ventilation path immediately after bathing, the air with high humidity is in the building 1 This is preferable because it reaches inside. In other words, it is desirable to fully consider the weather, seasons, etc. when placing the bathroom on the ventilation path.

Moreover, as another place which should be leeward, the room where a sick person exists is mentioned, for example. The room where the sick person is is in accordance with the room allocation among the residents, and it is uncertain which resident is the sick person. Therefore, the bedroom of the resident who has become sick is set as a place to be leeward each time. In addition, the room where this sick person exists is good also as a non-ventilated place which does not let a wind pass.
If both the toilets 4 and 12 and the room where the sick are are located on the selected ventilation route, the toilets 4 and 12 are basically leeward. , So that most of the residents do not pass through the toilet used by the residents, and discharge it to the outside.

In addition, examples of the non-ventilated place that does not allow the passage of wind include not only the place where the odor is generated and a room where a sick person is present, but also a room where air conditioning is performed independently from other rooms. That is, for example, the air conditioner 36 or the like may adjust the temperature of the room according to the individual preference of the resident, or may adjust the temperature of a dressing room or the like as a heat shock countermeasure.
Such a place where air conditioning is performed independently is set each time a ventilation route candidate is selected. Moreover, the room which is air-conditioning independently from other rooms is set so that the non-ventilated state continues until the setting is canceled.

Among the additional data, data including information on places that can be set in advance such as the toilets 4 and 12 and the kitchen 10 is referred to as first additional data for convenience of explanation. In addition, for convenience of explanation, the second additional data includes information on a place to be set when selecting a ventilation route, such as a room where a bathroom or a sick person is present, or a room where air conditioning is performed independently of other rooms. Called.
The building internal information data 27b stored in the data storage unit 27 of the storage unit 25 includes basic data stored in advance and additional data including the first additional data and the second additional data.
When the ventilation route selection system 20 is introduced into the building 1, the basic data and the first additional data are stored in advance in the data storage unit 27 of the storage unit 25 as part of the building internal information data 27b. deep. That is, what can be stored in advance as building internal information data 27b is stored in advance so that ventilation can be started immediately when ventilation is to be performed.

When attempting to ventilate a building, first, as shown in FIG. 5, a resident selects a ventilation target place (step S1). At this time, for example, the floor plan of the building 1 as shown in FIGS. 2 to 4 is displayed on the display monitor so that the resident can select the ventilation target place.
In addition, when the resident inputs information to the system or stores data in this manner, the input unit 24 is used.

In addition, the reference value of the ventilation frequency is set in advance in a room that can be selected as a ventilation target place.
Here, the number of ventilations is a numerical value representing how many times the room air is replaced with outside air per hour, and is a value obtained by dividing the ventilation amount by the room volume. The unit is represented by “times / hour (h)”. In this embodiment, the standard value for ventilation frequency is “Design guidelines for self-supporting recyclable housing (supervised by the National Institute for Land and Infrastructure Policy, Ministry of Land, Infrastructure, Transport and Tourism, Building Research Institute, Building Environment and Energy Conservation Organization). Issuing) ”and 10 times / h as a guide. Moreover, in this Embodiment, the ventilation frequency of 1 hour is measured as a predicted value by confirming how much ventilation was performed within predetermined time (for example, 10 minutes). Therefore, a plurality of sensors (airflow sensors) for detecting the air flow are also installed inside the building 1.
In addition, the reference value data of the indoor volume and the ventilation frequency is included in the building interior information data 27b and is set for each room. Further, the reference value data of the ventilation frequency is set according to the day, night, season, etc. with 10 times / h as a guide, and can be determined based on the above-described calendar / clock function. For example, since the temperature is higher at night than at night, the number of ventilations during the day is set higher than the number of ventilations during the night.

Subsequently, environmental information data 27a outside and inside the building 1 is acquired based on the environmental information acquisition program 26a (step S2).
That is, the wind direction / air volume sensor 30 and the outside air temperature sensor 31 measure the wind direction / air volume outside the building 1 and the outside air temperature, and the room temperature sensor 32 measures the room temperature inside the building 1. The data is stored in the data storage unit 27 as environment information data 27a.

Subsequently, ventilation route candidates are selected based on the ventilation route selection program 26b.
The ventilation path selection program 26b is set to select a ventilation path when the room temperature inside the building 1 is equal to or higher than the outside temperature. First, the room temperature and the outside temperature acquired based on the environment information acquisition program 26a are set. Are compared (step S3).
At this time, when the room temperature is lower than the outside air temperature, warm air is taken into the building 1 and the temperature inside the building 1 may rise. Therefore, the selection of the ventilation path and the ventilation of the building are finished. .

If the room temperature is equal to or higher than the outside air temperature, it is determined whether or not the outside air temperature is equal to or higher than 30 degrees (step S4).
When the outside air temperature is 30 ° C. or higher, the air conditioner 36 is assisted by a ventilation system different from the above-described ventilation path selection system 20 to promote a decrease in room temperature and an increase in warm air (step S5). ). In addition, when not introducing the ventilation system different from this ventilation path | route selection system 20, step S4 and step S5 are abbreviate | omitted.

If the outside air temperature is 30 ° C. or lower, a ventilation route candidate is selected (step S6).
Although details will be described later, in this step S6, based on the building internal information data 27b set and stored before step S1 and the ventilation route data 27c, the location not to be ventilated and the location to be leeward Is selected, and candidates for the ventilation path inside the building 1 are selected (steps S12 to S19).
Further, when selecting a ventilation path candidate in step S6, the ventilation effect can be calculated for each ventilation path candidate based on the ventilation effect determination program 26c and the ventilation resistance value data 27d.

Subsequently, based on the notification program 26d, the information on the ventilation path is notified to the resident using the output unit 23 such as a display monitor and a speaker (step S7). Examples of the contents to be notified include options of a plurality of ventilation path candidates, advice on ventilation effects of ventilation paths listed as candidates, and the like.
The resident selects an arbitrary ventilation path from among the ventilation path candidates selected in this way as a regular ventilation path for ventilating the building (step S8).

Subsequently, based on the ventilation effect determination program 26c and the reference value data of the room volume and the ventilation frequency of the ventilation target location included in the building internal information data 27b, the ventilation effect of the ventilation target location is determined by the ventilation frequency. It is determined whether or not the reference value is exceeded (step S9).
Here, if the ventilation frequency is less than the reference value, for example, the ceiling fan 34, the ventilation fan 35, etc. are operated as a ventilation assist device (step S10). That is, by operating the ceiling fan 34 and the ventilation fan 35, the air flow rate can be improved.
On the other hand, if the ventilation frequency is equal to or greater than the reference value, the entrance door 2b, fitting 3c, doors 3d, 4b, 7b, 9b, 12b, 13c, 14b, 15c, 16c, etc., are selected according to the selected ventilation path. The fitting is appropriately controlled to open the opening (step S11).
As described above, the ventilation path can be selected and ventilation of the building can be started. Note that such ventilation can be terminated by a resident's option, a timer, or the like, or can be automatically terminated based on environmental information.

  In addition, a ventilation path different from the regular ventilation path may be additionally selected as an auxiliary to the regular ventilation path. That is, for example, in the building 1 shown in FIGS. 3 and 4, a ventilation path F through which wind passes from the first floor to the second floor is used as an auxiliary.

Next, step S6 described above will be described in detail.
First, as shown in FIG. 6, based on the ventilation route selection program 26b, the environment information data 27a acquired by the environment information acquisition program 26a, and the information on the ventilation target location selected by the resident in step S1, It is determined from which opening of the building 1 the wind can be taken in, and at least one opening serving as a wind entrance is selected (step S12).

Subsequently, considering the structure of the building 1, the ventilation target location and the opening selected as the wind entrance in the ventilation route data 27 c including information on the configurations of all ventilation routes that can be selected as candidates are selected. The included ventilation path is selected as a temporary candidate (step S13).
That is, a ventilation path including a ventilation target location and an opening selected as a wind entrance is selected at random.

Based on the ventilation route selection program 26b, the building internal information data 27b, and the ventilation route data 27c, some of the selected temporary candidates for the ventilation route include a place to be leeward on the route. It is determined whether or not (step S14). At this time, it is determined that all the selected temporary candidates for the ventilation path are determined.
If any of the selected temporary candidates for the ventilation route includes a place to be leeward on the route, remove the temporary candidate for the ventilation route that has a place to be leeward on the route from the provisional candidates. (Step S15).

  If any of the selected temporary candidates for the ventilation route does not include a place to be leeward on the route, or excludes a provisional candidate for a ventilation route that has a place to be leeward on the route from the provisional candidates After that, among the remaining provisional candidates for the ventilation path, those that include a place not subject to ventilation are excluded from the candidates. At this time, first, the system side confirms whether or not there is a place where the resident is desired not to be ventilated (step S16).

If there is a place that is not to be ventilated, the resident uses the input unit 24 to select and input a place that is not to be ventilated (step S17).
The system side, after removing the temporary candidate of the ventilation path with the place to be leeward, from the remaining temporary candidates of the ventilation path, the temporary candidate of the ventilation path including the non-ventilated location entered by the resident Are excluded from the provisional candidates (step S18).

If the temporary candidate for the remaining ventilation route after removing the temporary candidate for the ventilation route that has a place to be leeward does not include the non-ventilated location entered by the resident, or is not subject to ventilation The provisional candidates for the ventilation path including the location are removed from the provisional candidates, and the remaining ventilation path candidates are regarded as regular candidates, and the ventilation effects of the regular candidates for these ventilation paths are calculated (step S19).
The calculation of the ventilation effect of the normal candidate of the ventilation path is performed based on the ventilation effect determination program 26c and the ventilation resistance value data 27d.
This ventilation resistance value data 27d is set for the configuration of the ventilation path and the fittings of each opening, and is stored in the data storage unit 27 in advance. That is, the ventilation resistance value data 27d is obtained by converting, for example, joinery, obstacles, corners, and the like into numerical values. Using the ventilation resistance value data 27d, the ventilation path ventilation is determined based on the ventilation effect determination program 26c. Calculate the effect.
For example, the ventilation effect varies depending on how many joinery are present on the ventilation path, how many obstacles are present, how many corners exist, when the joinery is opened, or when the joinery is closed. Therefore, if the selected ventilation path is configured in a straight line without an obstacle, the ventilation effect is enhanced.

Next, the ventilation route selection method while the resident is out and the ventilation method of the building including this ventilation route selection method will be described. Hereinafter, the ventilation route selection method while the resident is out is referred to as an outing mode. On the other hand, the above-described normal ventilation route selection method is referred to as a normal mode.
In the description of the outing mode, constituent parts different from the above-described normal ventilation route selection method will be described in detail, and only the outline of the same constituent parts will be described.

In this outing mode, as shown in FIG. 7, first, the resident sets the outing start time (step S20). The ventilation route selection device 21 is provided with a calendar / clock function, and can use a control or a timer function corresponding to the date and time, so that the start time of going out can be set using this function. . Therefore, in the outing mode, the ventilation path can be automatically selected and the building can be ventilated when the outing start time set by the resident is reached.
In this step S20, not only the start time to go out but also the scheduled return time may be set.

Subsequently, the system side confirms whether or not there is a place where the resident is desired not to be ventilated (step S21).
When there is a place that is not to be ventilated, the resident uses the input unit 24 to select and input a place that is not to be ventilated (step S22). The ventilation non-target location selected in step S22 is referred to when a provisional candidate for the ventilation route is selected in a subsequent process.

Subsequently, when there is no place to be excluded from ventilation, or after selecting a place to be excluded from ventilation, the human sensor 33 is activated (step S23).
Then, the presence / absence of the resident is confirmed by the human sensor 33 (step S24), and if the resident is still at home, the detection operation is continued until the resident is absent.
After the resident is absent, environmental information data 27a outside and inside the building 1 is acquired based on the environmental information acquisition program 26a (step S25).

Subsequently, ventilation route candidates are selected based on the ventilation route selection program 26b.
First, the room temperature acquired based on the environmental information acquisition program 26a is compared with the outside air temperature (step S26).
At this time, if the room temperature is lower than the outside air temperature, warm air is taken into the building 1 and the temperature inside the building 1 may rise. Therefore, the room temperature inside the building 1 exceeds the outside air temperature. Environmental information is acquired intermittently until.

If the room temperature is equal to or higher than the outside air temperature, it is determined whether or not the outside air temperature is equal to or higher than 30 degrees (step S27).
If the outside air temperature is 30 ° C. or higher, the air conditioner 36 is assisted to drive down the room temperature and increase the warm air (step S28).

  Subsequently, based on the ventilation route selection program 26b, the environment information data 27a acquired by the environment information acquisition program 26a, and the information on the ventilation non-target location selected by the resident in step S22, any of the buildings 1 It is determined whether or not wind can be taken in from the opening, and at least one opening serving as a wind inlet is selected (step S29).

Subsequently, in consideration of the structure of the building 1, the ventilation path data 27 c including information on the configurations of all ventilation paths that can be selected as candidates is selected as a wind entrance that does not include a ventilation non-target place. A ventilation path including the opening is selected as a temporary candidate (step S30).
In other words, a ventilation path that does not include a ventilation non-target location and includes an opening selected as a wind inlet is randomly selected.

Subsequently, it is determined whether or not any of the selected temporary candidates for the ventilation route includes a place to be leeward on the route (step S31).
If any of the selected temporary candidates for the ventilation route includes a place to be leeward on the route, remove the temporary candidate for the ventilation route that has a place to be leeward on the route from the provisional candidates. (Step S32).

If any of the selected temporary candidates for the ventilation route does not include a place to be leeward on the route, or excludes a provisional candidate for a ventilation route that has a place to be leeward on the route from the provisional candidates After that, the remaining ventilation path candidates are regarded as normal candidates, and the ventilation effects of these normal ventilation path candidates are calculated (step S33).
And the thing with the highest ventilation effect is selected as a regular ventilation path | route among these normal candidates of a ventilation path | route (step S34).

Subsequently, based on the ventilation effect determination program 26c and the reference value data of the room volume and the ventilation frequency of the ventilation target location included in the building internal information data 27b, the ventilation effect of the ventilation target location is determined by the ventilation frequency. It is determined whether or not it is equal to or greater than a reference value (step S35).
Here, if the ventilation frequency is less than the reference value, for example, the ceiling fan 34, the ventilation fan 35, and the like are operated as a ventilation assist device (step S36) to improve the ventilation rate.
On the other hand, if the ventilation frequency is equal to or greater than the reference value, the entrance door 2b, fitting 3c, doors 3d, 4b, 7b, 9b, 12b, 13c, 14b, 15c, 16c, etc., are selected according to the selected ventilation path. The fitting is appropriately controlled to open the opening (step S37).
As described above, the ventilation route can be selected and ventilation of the building can be started even when the resident is out. Note that such ventilation in the outing mode can be terminated by a timer or the like, or can be automatically terminated based on environmental information.

In addition, the ventilation route selection system 20 according to the present embodiment may be configured to select a ventilation route while the occupant is sleeping and to select a sleeping mode that ventilates the building. Shall.
This sleeping mode is substantially the same as the normal mode. The major difference from the normal mode is that the reference value of the ventilation frequency at the place to be ventilated is set smaller than when it is awake (in normal mode). The point and the point which concerns on control of the opening width of the opening part at the time of introducing external air into the building 1 inside are mentioned.
The reason why the reference value of the ventilation frequency during the sleep mode is smaller than the reference value of the ventilation frequency during the normal mode is to prevent the body from cooling down during the sleep mode.
The reason why the opening width of the opening is controlled is to prevent intrusion of rainwater during sudden rain and intrusion of human beings other than residents into the building 1. Therefore, the shutter device 37 is particularly utilized during the sleep mode.

Next, an example of the ventilation path in the case of the building 1 will be described.
On the first floor of the building 1 shown in FIG. 2, the living room 7 is set as a ventilation target place, and the kitchen 10 is set as a non-ventilation target place or a place to be leeward.

  When the kitchen 10 is a place to be leeward and the wind around the building 1 is the northward wind W1 (that is, the wind blowing from the lower side to the upper side in FIG. 2), the wind W1 is It is possible to select the ventilation path A that is taken into the living room 7 that is the ventilation target place from the opening 7a, passes through the dining room 9 and flows into the kitchen 10, and is discharged from the opening 10a of the kitchen 10 to the outside.

  When the kitchen 10 is a non-ventilated place and the wind around the building 1 is the southwest facing wind W2 (that is, the wind blowing from the upper right side to the lower left side in FIG. 2), W2 can be taken into the dining room 9 from the opening 9a, flowed into the living room 7 without passing through the kitchen 10, and the ventilation path B discharged from the opening 7a of the living room 7 to the outside can be selected.

  Further, the kitchen 10 is a place not to be ventilated or a place to be leeward, and the wind around the building 1 is a southward wind W3 (that is, a wind blowing from the upper side to the lower side in FIG. 2). In this case, since the wind W3 must flow into the kitchen 10, the ventilation path C in FIG. 2 cannot be selected as a ventilation path candidate.

  In the case of the building 1 shown in FIG. 2, the resident can select the ventilation path selected by the ventilation path selection program 26b among the ventilation paths A and B selected according to the environmental information data 27a. The ventilation path C cannot be selected basically, and the building internal information data 27b needs to be changed.

  Subsequently, FIG. 3 shows the first floor of the building 1, and FIG. 4 shows the second floor of the building 1. On the second floor of the building 1 shown in FIG. 4, the first child room 15 is set as a ventilation target location, and the second child room 16 is set as a ventilation non-target location. In addition, a wind W4 blows around the building 1 north and northeast.

In FIG. 4, the wind W4 is taken into the second-floor bedroom 13 through the opening 13a, passes through the corridor 11 and flows into the first child room 15, and is discharged from the opening 15b of the first child room 15 to the outside. The route D and the wind W4 are taken into the second child room 16 from the opening 16a, pass through the corridor 11, and flow into the first child room 15, and are discharged from the opening 15b of the first child room 15 to the outside. A ventilation path E is shown.
In this case, the resident cannot select the ventilation path E including the second child room 16 set as the ventilation non-target place among the ventilation paths D and E, and can select the ventilation path D.

Furthermore, in addition to the ventilation path D, the resident can additionally select the ventilation path F as an auxiliary. The ventilation path F merges with the ventilation path D in the vicinity of the upper end portion of the stairs 6 so that the ventilation effect at the ventilation target location can be improved.
Such auxiliary ventilation route information is notified as advice to the resident based on the notification program 26d.

  The ventilation path selected by the ventilation path selection system 20 is selected from all the ventilation path candidates in the building due to various factors such as the structure and location of the building, the local climate, weather, and seasons. Therefore, it is not limited to the above-described ventilation paths A, B, C, D, E, and F, and can be changed as appropriate.

According to the present embodiment, the control unit 22 is based on the environmental information data 27a acquired by the environmental information acquisition means configured by the control unit 22 and the environmental information acquisition program 26a and the building internal information data 27b. And the ventilation path selection means constituted by the ventilation path selection program 26b and the like determine the place not to be ventilated and the place to be leeward, and then select candidates A, B, C, D, E, and F of the ventilation path. Since the resident can be selected, the resident can appropriately select a ventilation path in consideration of a place not to be ventilated and a place to be leeward from the selected candidates.
As a result, for example, the odors of the toilets 4 and 12 and the kitchen 10 are spread throughout the building 1 due to ventilation, or the air environment of the room that is air-conditioned independently of other rooms is hindered. Since this can be reliably prevented, it is possible to form a comfortable living environment for the resident.

  Moreover, since the place which should not be ventilated and the place which should be leeward is set to the room which emits odors, such as the toilets 4 and 12, the kitchen 10, etc., the wind which flowed into the inside of the building 1 is the place which is not subject to ventilation. In addition to being avoided, the place to be leeward is discharged to the outside of the building 1 as the final passing place. As a result, it is possible to reliably prevent odors from spreading throughout the building 1 through the ventilation path.

  In addition, because the place that is not subject to ventilation and the place that should be leeward are set in the room where the sick are, the wind that has flowed into the building 1 avoids the place that is not subject to ventilation and the place that should be leeward. It will be discharged outside the building 1 as the final passage location. Thereby, it is possible to reliably prevent pathogens scattered in the air as sprays and chemical odors from spreading throughout the building 1.

  In addition, the non-ventilated place is set in a room that is air-conditioned independently of the other rooms, so that the wind that flows into the building 1 is outside the building 1 while avoiding the non-ventilated place. Will be discharged. Thereby, the air environment of the place where air conditioning is performed independently from other places can be reliably held without being obstructed by the wind flowing into the building 1.

In addition, since the presence sensor 33 that detects the presence / absence of the resident is provided, the presence / absence of the resident can be detected. The absence of air can be detected to stop ventilation.
In addition, the location where ventilation is not possible and the location to be leeward in the absence are set in rooms that emit odors such as the toilets 4, 12, kitchen 10, etc. Can be reliably prevented from spreading throughout the building through the ventilation path.

  Moreover, since the information program 26d for notifying the resident of the information related to the ventilation path is provided, for example, a plurality of ventilation paths are displayed as options or the ventilation effect of the ventilation path is displayed by the notification means. Or a suitable ventilation route can be advised. As a result, the resident can arbitrarily select a ventilation path suitable for himself, check the ventilation effect of the ventilation path as appropriate, or select a ventilation path according to the advice. It is possible to easily obtain an air environment according to the intention of the resident.

  Further, the ventilation assist devices such as the ceiling fan 34 and the ventilation fan 35 are set to operate when the ventilation frequency in the location to be ventilated is less than a reference value, so that the wind is allowed to flow into the building 1. However, if it is determined that the ventilation frequency at the ventilation target location does not reach the reference value, ventilation assistance can be performed by the ventilation assist device, and the ventilation frequency at the ventilation target location can be increased.

  In addition, since the shutter device 37 is provided on the outer wall of the building 1 to allow ventilation while blocking intrusion of people through the opening 3a and the line of sight from the outside, the shutter 1 can be used when the resident is absent or sleeps. Even inside, it is possible to ventilate by opening the opening 3a and the like. As a result, the air environment inside the building 1 can be kept good even when the resident is absent or sleeping, so that discomfort such as hot air at the time of going home can be reduced, and sleepiness at night in midsummer can be reduced. Can be eliminated.

  In addition, the entrance door 2b and the doors 3d, 7b, 12b, etc. in the building 1 are set to be openable / closable according to the ventilation path selected by the resident among the candidates, so that the resident can change the ventilation path. When selected, the entrance door 2b and the doors 3d, 7b, 12b in the building 1 can be automatically controlled to be opened and closed. This facilitates the flow of wind into the building 1 and can save the resident himself from opening and closing the entrance door 2b and the doors 3d, 7b, 12b and the like inside the building 1.
