An air state changing device 16 for changing the state of air disposed in an air passage between the air blower 15, the air state changing device 16, and the notification device 8 based on a target set by the user Us on the operation unit 5. And a control unit 17 for controlling the

  The air condition changing device 16 is, for example, a device for adjusting the quality of air in the living room 2, such as a humidifying device for increasing humidity, a dehumidifying device for decreasing humidity, a heating device for increasing temperature, a cooling device for decreasing temperature, and a fragrance.

  In the present embodiment, a humidifier is provided.

  Further, an air path switching damper 21 is provided as the exhaust device 20. The air path switching damper 21 switches the flow direction of air from the outlet 7 side to the outlet 11 in the main body of the air environment adjusting device 1 (in the case of switching to the white arrow direction side in FIG. 2). It is. Thereby, when the blower 15 is operated, the airflow can be discharged to the outdoor side.

  As shown in FIG. 3, the control unit 17 includes at least an acquisition unit 23, a clock unit 24, a storage unit 29 storing physical control values, achievement degrees, and delay times as information, a processing unit 30, Means 31.

  The acquisition unit 23 acquires a signal of a detection signal of the sensor 8 and a signal of a target command from the operation unit 5.

Time measuring means 24 is to start the time measurement from the time of the operation unit 5 receives the signal as a command for targets.

Storage means 29, the signal and associating a physical control value of the blower 15 and an air state change device 16 of the acquisition unit 23, and achievement of the goals that are referenced from the input value of the sensor 8, and the change in the air in the state On the other hand, each of the delay times until a person perceives the change is stored as information. For example, a temperature, a humidity, and a target (“very moist”, “slightly moist”, “moist”) as shown in FIG. 5 or a temperature and a CO2 concentration as shown in FIG. And the target.

The processing means 30 calculates the physical control value and the degree of achievement of the target from the signal of the obtaining means 23 and the above-mentioned information.

  The instructing means 31 instructs the blower 15, the air condition changing device 16, and the notification unit 9 to operate based on the signal of the processing means 30.

In the above configuration, when the user Us wants to obtain a moist feeling (moist feeling) with respect to the air in the living room 2, for example, the operation unit 5 presses an operation button displayed as “very moist”.

When the operation of such desired sense as the target, the transmitted signal as a command of the target from the operation unit 5 to the remote control receiving portion 10 of the air environment adjusting apparatus 1 main body, signals are sent further to the control unit 17. Control unit 17, the signal as command targets (hereinafter, the target signal) acquired, and acquires the state of the air in the room 2 from the sensor 8 at the same time. Subsequently, the control unit 17, from the acquired signal (air condition) from the sensor 8, defines a physical control value, the blower 15 based on the physical control value, it actuates the air state change device 16.

  The air condition changing device 16 of the present embodiment is a humidifier, and can increase the humidity of the living room 2. When the blower 15 operates, the air in the living room 2 is sucked in from the suction port 6, the air is humidified by the air state changing device 16, and is blown out from the air outlet 7 into the living room 2.

  The control unit 17 records the time-series transition of the temperature and humidity in the living room 2 from the sensor 8 at predetermined time intervals. Then, by grasping the change tendency of the temperature and the humidity in time series by the control unit 17, it is possible to estimate the degree of achievement of the target at that time (time) and the time at which the achievement of the target can be perceived. If the estimated time is not reached, the notifying unit 9 outputs the color temperature of the light emitter associated with the degree of achievement of the target, and issues a command to the notifying unit 9. When the estimated time has come, a command is issued to the notification unit 9 to output a color temperature associated with the degree of achievement of the target. At this time, the control unit 17 issues a command to increase the output of the light emitter as the degree of achievement of the target is higher.

  The control contents of the control unit 17 will now be described with reference to FIG.

For example, when the operation unit 5 acquiring unit 23 a target of the signal of "very moist" from receives, along with the current temperature and humidity signal in the latest room 2, the signal of goals to the processing means 30 is sent. Processing means 30 stores from their No. signal, as a time t = 0 the signal temperature and humidity in the storage unit 29. When receiving the target signal, the processing means 30 starts the operation of the time keeping means 24 (step 1). Note that the timer 24 can send a signal to the processor 30 at predetermined time intervals, and in the present embodiment, the predetermined time interval, which is a unit time, is set to one minute.

  Next, the processing unit 30 refers to the signal obtained from the obtaining unit 23 and the information in the storage unit 29. The storage means 29 stores the physical control value relating to the moist feeling at each temperature, the degree of achievement of the moist feeling, and the moist feeling (relative to the humidity for realizing the moist feeling), that is, the delay time as the time until the humidity change can be realized. Information is stored.

Here, the processing means 30 calculates a physical control value associated with “very moist” of the target signal. For example, in the case of an air environment of 22 ° C., the relative humidity, which is a physical control value, is 56%. After calculating the physical control value, the processing means 30 sends a signal to the instruction unit 31 a physical control value, indicating means 31 operates the blower 15 and the air condition change unit 9 on the basis thereof (Step 2).

  Further, the processing means 30 associates the temperature and humidity signals at that time with the degree of achievement of the moist feeling “very moist”. For example, as shown in FIG. 5, in an air environment at a temperature of 22 ° C., “very moist” achieves 100% when the humidity is 56% and 0% when the humidity is 40%. The 50% point at 22 ° C. where the relative humidity is between these two points is calculated linearly and the degree of achievement is calculated as follows.

That is, 100 [%] ÷ (56 [ % ]-40 [ % ]) × (50 [%]-40 [%]) = 62%.

  The processing means 30 transmits the signal of the degree of achievement of the target calculated in this way to the instruction means 31.

  The instructing unit 31 instructs the notification unit 9 to display the information based on the degree of achievement, associating as shown in FIG. For example, as shown in (a) and (d) of FIG. 6 (in FIG. 6, the degree of achievement of the target is indicated as the degree of achievement. Hereinafter, this is referred to as “color temperature”). May be changed stepwise. Further, as shown in FIG. 6A, the scale may be raised stepwise. Further, as shown in FIG. 6C, the processes from flower bud to flower blossoming may be associated stepwise, and any process that changes stepwise may be used.

In the present embodiment, the achievement degree of “very moist” is associated with the stepwise change of the color temperature in FIG. 6A, and when the achievement degree is 62% , The luminous body provided in the notification unit 9 outputs a color temperature of 4000K.

  In addition to the change in the color temperature, the output value of the luminous body is adjusted according to the degree of achievement. In the present embodiment, when the degree of achievement is 100%, when the luminous body shows 10 W (watt), it is calculated linearly, and when it is 62%, the degree of achievement is made clearer by outputting at 6.2 W. (Step 3).

  After step 3, the processing unit 30 stores the temperature and humidity signals obtained from the acquisition unit and the target signal in the storage unit 29 (step 4).

  If the predetermined time interval set in the timer 24 has not elapsed after the completion of the processes of Steps 1 to 4, the process returns to (a) as shown in FIG. If the time has elapsed, a signal is sent from the timing means 24 to the processing means 30 (step 5).

  Based on this signal, the processing unit 30 collects the signal of the sensor 8 from the acquisition unit, and stores the temperature / humidity signal at time t = 1 in the storage unit 29 (Step 6).

  Next, the processing unit 30 refers to the signal obtained from the obtaining unit 23 and the information in the storage unit 29. Here, the processing means 30 calculates a physical control value associated with “very moist” from the target signal, and changes it appropriately. After calculating the physical control value, the processing unit 30 sends a signal to the instruction unit 31 with the changed physical control value.

  The instructing means 31 moves the blower 15 and the air condition changing unit 9 based on the changed physical control value (Step 7).

  Further, the processing means 30 associates the temperature and humidity signals at that time with the degree of achievement of the moist feeling, and calculates the degree of achievement. Then, based on the calculated degree of achievement, the notifying unit 9 is operated via the instructing means 31, and a command is issued to the notifying unit 9 based on the associated color temperature of the illuminant and the output value (step 8). ).

  Next, as a predetermined time, at time t = 1, a time at which it is estimated that the user Us can perceive the achievement of the target is calculated. An example of the calculation method is described below.

  First, the time at which the physical control value is achieved is calculated. As shown in FIG. 5, the humidity at time t = 0 was 40%, and the humidity at time t = 1 was 43%. In this case, when the calculation is performed linearly, the calculation is performed as follows, and it is estimated that the target is achieved at time t = 6.

First, as the observed humidity change rate,
(43 [ % ]-40 [ % ]) ÷ (1 [t] -0 [t]) = 3 [% / Δt]

Next, the time required to reach the target humidity is
(56 [ % ]-40 [ % ]) ÷ 3 [% / Δt] = 5.3 [t] Since the unit time is 1 minute, it can be estimated to be 5.5 [minutes].

  Further, a delay time is calculated. In the case of "very moist", the physical control value to be operated is humidity. Generally, the higher the temperature, the more easily the humidity is perceived. As an example, the delay time at 20 ° C. is set to 5 minutes, the delay time at 25 ° C. is set to 0 minutes, and the delay time at 22 ° C. can be estimated linearly as follows.

The delay time is
(5 [minutes] -0 [minutes]) / (25 [° C] -20 [° C]) x (22 [° C] -20 [° C]) = 1.5 [minutes].

Since the time to reach the goal is 5.3 minutes and the delay time is 1.5 minutes,
5.3 [minute] ÷ 1 [minute / Δt] +1.5 [minute] ÷ 1 [minute / Δt] = 6.8 [t],
That is, the time until it is estimated that achievement of the goal is perceived is 6.8 minutes. Since the current time t = 1, it is presumed that when the time is reached, it is possible to perceive that the target achievement has been perceived when the time t = 7.8 has been reached.

  The processing unit 30 records the estimated time in the storage unit 29 (step 9).

  After the process from step 6 to step 9, if the predetermined time interval set in the timer 24 has not elapsed, the process returns to the state shown in FIG. If the predetermined time interval has elapsed, the timer 24 sends a signal to the processor 30 (step 10).

  The processing unit 30 refers to the estimated time from the storage unit 29 and determines whether the current time has arrived. If the time at which it is estimated that the arrival at the target can be perceived has not passed, the process returns to step 6 following (c) as shown in FIG. Here, if the time at which it is estimated that the arrival at the target can be perceived has elapsed, the fact that the degree of achievement is 100% is transmitted to the instruction unit 31 (step 11).

Since the degree of achievement is 100%, the instruction unit 31 instructs the notification unit 9 of the associated output. In this embodiment, when the degree of achievement is 100%, the output is set to 10 W at a color temperature of 2000 K. Based on the output, the notification unit 9 is operated to inform the user Us that the target “very moist” has been reached. (Step 12). Then, the operation ends.

  The example of the operation for the goal of “very moist” has been described above. Next, an operation example for the goal of “very refreshing” will be described.

  In the present operation example, it is possible to drive the reduction of the CO2 concentration with a feeling of "freshness" by the ventilation operation, and the operation will be described with reference to FIGS.

In the configuration described above, when the user Us wants to obtain a refreshing feeling about the air, the user presses the operation button of the operation unit 5 which is displayed as "Very refreshing".

  When an operation is performed with such a desired sensation as a target command, a target signal is transmitted from the operation unit 5 to the remote control reception unit 10 of the air conditioner 1, and a signal is transmitted to the control unit 17. The control unit 17 acquires the target signal, and at the same time, acquires the state of the air in the living room 2 from the signal of the sensor 8. The control unit 17 determines a physical control value from these acquired signals, and operates the blower 15 and the air path switching damper 21 based on the physical control value.

  The air path switching damper 21 according to the present embodiment is a plate fixed by a hinge for switching the air path, and the air path is switched by closing the air outlet 7 and opening the discharge port 11 so that the living room 2 becomes dirty. The air can be exhausted outdoors. When the blower 15 operates, the air in the living room 2 is sucked in from the inlet 6, and the air is sent out from the outlet 11 by the air path switching damper 21 and blown out through the duct.

  The control unit 17 records the time-series transition of the temperature and the CO2 concentration in the living room 2 from the sensor 8 at predetermined time intervals, and the control unit 17 grasps the change tendency of the temperature and the CO2 concentration in a time-series manner. It is possible to estimate the degree of achievement of the target at that time and the time at which the target can be perceived. If the estimated time is not reached, a command is issued to the notifying unit 9 to output the color temperature of the luminous body corresponding to the degree of achievement as shown in FIG. When the estimated time has come, a command is issued to the notifying unit 9 to output the color temperature associated with the target. At this time, the control unit 17 issues a command such that the higher the degree of achievement, the higher the output of the light emitter.

  The acquisition unit 23 of the control unit 17 can acquire signals from the sensor 8 and the operation unit 5.

  The control contents of the control unit 17 will now be described with reference to FIG.

  When the acquisition unit 23 receives a target signal “very refreshing” from the operation unit 5 as a target command, the target signal is transmitted to the processing unit 30 together with the latest signal of the current temperature and CO2 concentration in the living room 2. Is done.

  The processing unit 30 stores the signal of the temperature and the CO2 concentration in the storage unit 29 with the signal as time t = 0. When the processing means 30 receives the target signal, the processing means 30 outputs a signal to the time counting means 24 to start the operation (step 1). The clock unit 24 can send a signal to the processing unit 30 at predetermined time intervals, and is set to one minute in the present embodiment.

  Next, the processing unit 30 refers to the signal obtained from the obtaining unit 23 and the information in the storage unit 29. The storage unit 29 stores information on the physical control value of the moist feeling at each temperature, the degree of achievement of the refreshing feeling, and the delay time for the CO2 concentration for realizing the refreshing feeling.

  Here, the processing means 30 calculates a physical control value associated with “very refreshing” of the target signal. For example, in the case of an air environment of 22 ° C., the physical control value is 1000 ppm. After calculating the physical control value, the processing means 30 sends a signal to the instruction means 31 for the physical control value, and the instruction means 31 moves the blower 15 based on the signal (step 2).

  Further, the processing unit 30 associates the temperature and CO2 concentration signals at that time with the degree of achievement of the refreshing feeling of "very refreshing". For example, as shown in FIG. 9, in an air environment at a temperature of 22 ° C., “very refreshing” is achieved 100% when the CO2 concentration is 1000 ppm, and is 0% when the CO2 concentration is 1900 ppm. By calculation, the degree of achievement at the time of 22 ° C. and 1500 ppm is calculated as follows.

That is, 100 [%] ÷ (1000 [ppm] -1900 [ppm]) × (1500 [ppm] -1900 [ppm]) ≒ 44 [ % ] .

  The processing means 30 transmits a signal indicating the degree of achievement calculated in this way to the instruction means 31. The instructing means 31 instructs the notifying unit 9 to display based on the degree of achievement, associating as shown in FIG.

  In the present embodiment, the achievement degree of “very refreshing” is associated as shown in FIG. 6D, and when the achievement degree is 44%, the color temperature of 5000 K is output. .

  In addition, the output value of the light emitter is adjusted according to the degree of achievement. In the present embodiment, when the luminous body shows 10 W when the achievement degree is 100%, it is calculated linearly, and when it is 44%, it is output at 4.4 W to express the achievement degree. (Step 3).

  After step 3, the processing unit 30 stores the CO2 concentration signal obtained from the acquisition unit and the target signal in the storage unit 29 (step 4).

If the predetermined time set in the timer 24 has not elapsed after the completion of the processes in steps 1 to 4, the process returns to (a) as shown in FIG. If the time has elapsed, a signal is sent from the timing means to the processing means 30 . Processing means 30, this signal, collects the signal of the sensor 8 from the acquisition unit 23. The latest temperature and CO2 concentration signals in the living room 2 are received from the sensor 8 at predetermined time intervals, and the latest temperature and CO2 concentration in the living room 2 are always recorded in the acquisition means 23. the signal acquisition, as a time t = 1, stores the signal of the temperature and CO2 concentration in the storage unit 29 (step 6).

  Next, the processing unit 30 refers to the signal obtained from the obtaining unit 23 and the information in the storage unit 29. Here, the processing unit 30 converts the physical control value associated with “very refreshing” from the target signal. Calculate and change as appropriate. After calculating the physical control value, the processing unit 30 sends the physical control value to the instruction unit 31, and the instruction unit 31 operates the blower 15 based on the physical control value (step 7).

Further, the processing means 30 associates the temperature and CO2 concentration signals at that time with the achievement degree of the refreshing feeling, and calculates the achievement degree. Subsequently, through the instruction unit 31 on the basis of achieving a degree activates the notifying unit 9 issues a color temperature of the light emitting element associated with a command to the notification section 9 on the basis of the output value (Step 8) .

  Next, at time t = 1, a time at which it is estimated that the target is perceived is further calculated. An example of the calculation method is shown below.

  First, the time at which the physical control value is achieved is calculated. The CO2 concentration at the time t = 0 is 1900 ppm, the CO2 concentration at the time t = 1 is 1800 ppm, and when linearly calculated, it is calculated as follows, and the target is achieved at the time t = 6. At time t = 1.

First, as the rate of change of the observed CO2 concentration,
(1800 [ % ]-1900 [ % ]) ÷ (1 [ t ] -0 [ t ]) = − 100 [% / Δt ] can be calculated. Next, the time required to reach the target CO2 concentration is
(1000 [ % ]-1900 [ % ]) ÷ (−100) [% / Δt ] = 9 [ t ] Since the unit time is 1 minute, it can be estimated to be 9 [minute].

Further, a delay time is calculated. In the case of "very refreshing", the physical control value to be operated is the CO2 concentration. Generally, the higher the temperature, the more easily the CO2 concentration is perceived. As an example, the delay time at 20 ° C. is set to 60 minutes, the delay time at 25 ° C. is set to 45 minutes, and the delay time at 22 ° C. can be estimated linearly as follows.
(60 [minutes] -45 [minutes]) ÷ (25 [° C] -20 [° C]) × (22 [° C] -20 [° C]) = 10 [minutes]
The goal is 9 minutes and the delay is 10 minutes,
9 [minutes] ÷ 1 [minutes / Δt ] +10 [minutes] ÷ 1 [minutes / Δt ] = 19 [ t ]
That is, the time until it is estimated that achievement of the goal can be perceived is 19 minutes.
Since the current time t = 1, it is assumed that when the time is reached, the target achievement can be perceived when the time t = 20 is reached.

  The processing unit 30 records the estimated time in the storage unit 29 (step 9).

  After the process from step 6 to step 9, if the predetermined time interval preset in the timer 24 has not elapsed, the process returns as shown in FIG. 8B. If the predetermined time interval has elapsed, the timer 24 sends a signal to the processor 30 (step 10).

  The processing unit 30 refers to the estimated time from the storage unit 29 and determines whether the current time has reached the estimated time. If the time at which it is estimated that the target can be perceived has not passed, the process returns to step 6 following (c) as shown in FIG. Here, if the estimated time has elapsed, the informing unit 31 is informed that the achievement degree is 100% (step 11).

  Since the degree of achievement is 100%, the instruction unit 31 instructs the notification unit 9 of the associated output. In the present embodiment, when the degree of achievement is 100%, the output value is 10 W at a color temperature of 8000 K, so that the notifying unit 9 is operated based on the output value to inform the user Us that the target can be perceived as “very refreshing”. (Step 12). Then, the operation ends.

  In addition, as a method of associating the physical value with the target, it is desirable to create the data based on the data of the subject experiment. For example, multiple conditions are set for temperature and humidity, and multiple subjects are allowed to stay, and a questionnaire survey is conducted to determine how much the target sensations (moist, refreshing, warm, cool, fresh, clean, etc.) are felt. Then, by grasping the tendency, it is possible to make correspondence. The evaluation method includes the Likert method, the SD method, and the like. The degree can be evaluated stepwise and the distribution can be checked to determine the degree.

  In the subject experiment for linking to such a goal, a more accurate connection can be made by accumulating a large amount of experimental data on young and old and men and women of various attributes.

  As for the delay time, it is considered that the delay time until the change is perceived in the order of the fragrance concentration, the temperature, the humidity, and the CO2 concentration becomes longer.

  In the case of the fragrance concentration, odor molecules in the air dissolve into the olfactory mucosa and are stimulated by the olfactory cells, which are receptors, to reach the brain, where they are transmitted quickly. As for temperature, peripheral sensory nerves in human skin transmit temperature stimuli to the brain, but it takes time for the temperature to transmit to receptors in the skin. In addition, no direct receptor has been found for humidity, and it is perceived as slower than perfume concentration and temperature because it is sensed by dry mucous membranes and changes in skin and hair. Also, the CO2 concentration is a colorless and odorless gas, and if it is a concentration that generally occurs, it does not directly feel the concentration, but it acts on the body eventually by continuing to dissolve into the blood from the lungs. CO2 concentration is the most time-consuming to perceive.

  In deriving the delay time for a new element other than the above, it is desirable to create the delay time based on the data of the subject experiment. By staying in the experimental space for a certain period of time and examining how it feels when the environment changes, it is possible to understand how long people can perceive after physical value changes .

  As a method of associating the expression used for the notification with the degree of achievement, it is desirable to extract many opinions and derive an appropriate expression through a Web survey, a group interview, or the like. For example, prepare a large number of images that change in stages in advance, arrange them in the order that the subjects think that they will change in stages, and analyze the data to derive the order in which the majority thinks that it will increase in stages. You may.

  In addition, as a method of obtaining appropriate expressions, we investigate what expressions are appropriate for the target words of sensation such as "moist feeling" and "refreshing feeling" and use the ones selected by more than half Thereby, a more empathetic expression can be extracted. In addition, by unifying the attributes of the surveyees at this time, it is possible to extract an expression that a person with a more specific attribute can sympathize with. For example, by aligning information such as gender, age, and hobby, a more appropriate expression may be extracted, and an expression according to the user's preference may be set in advance.

  The expression associated with the degree of achievement is not limited to the expression shown in FIG. 6 as long as the state of the stepwise change can be understood. Although the musical scale is used as an example of the auditory expression, for example, the musical scale may be a single tone or a chord, and may be a sound that gradually increases or decreases. The direction in which the scale changes may be not only the ascending direction but also the descending direction. Examples of visual expressions are color temperature changes and time-series changes in flowers.For example, puzzles with pictures and illustrations may be assembled, or landscape images may be displayed in the morning. It may be a state that changes from time to time such as from night to night.

  What the air environment adjusting device 1 provides does not necessarily need to be “moist” or “fresh”. As other expressions relating to the comfort of air, a feeling that can be obtained from the air state such as “warm”, “cool”, “fresh”, and “clean” can be set as a target.

  The operation buttons in the operation unit 5 do not necessarily need to be set in stages, and may be only “fresh” and “moist”. Further, even when the setting is performed stepwise, the expression is not limited to “slightly” or “very”, but may be expressed in another expression such as “slightly” or “significantly”.

  It should be noted that the manner of associating with the achievement level does not necessarily need to be determined at the intervals shown in FIG. 6, and the range may be divided into equal intervals, or the range may be reduced as the achievement level increases. Moreover, the calculation method of the achievement degree is an example, and does not necessarily need to be linear regression.

  It is not always necessary to stop the operation after the process is completed, and the operation may be based on an instruction from the user Us, or may be ended after a certain time elapses by setting a timer or the like.

  The air environment adjusting device 1 does not necessarily need to be installed on the ceiling 3 and may be installed on the floor surface, the wall 4, or the like. Further, it may not be embedded in the ceiling 3 or the wall 4 and may be an independent structure that can be moved and carried.

  The operation unit 5 does not need to be hung on the wall 4 and may be freely detachable. In addition, the operation unit 5 may be one that introduces and uses an application in another device such as a tablet terminal or a mobile phone. Further, it is not always necessary to provide the operation section 5 separately from the main body, and the operation section 5 may be provided on the main body.

  In addition, the air environment adjusting device 1 is not limited to a humidifier or a ventilation fan, but includes an aroma diffuser for generating fragrance, a dehumidifier for lowering humidity, an ion generator for increasing ion concentration in the air, and discharging water droplets to the air. Any device that can act on a person by changing the state of air, such as a mist generator that generates air, a heating device that raises the temperature of air, and a cooling device that lowers the temperature of air, may be used.

According to the present invention, the processing unit adds the target achievement time calculated from the time-series change in the degree of achievement of the target, and the delay time until a person can perceive the change in the air quality change. hand,
I guess time that can perceive objectives and reaches the guessed time, via the instruction means, and the configuration of actuating the notification unit. With this, when the feeling obtained from the state of the air is set as a target by the operation unit, the processing unit calculates the physical control value and the degree of achievement of the target from the storage unit together with the input value of the sensor and is input to the acquisition unit, and The air condition changing device and the notification unit are operated.

In particular, processing means, by adding up and achieved time of the target, which is calculated from the time series changes of achieving the degree of goals, and a delay time until the user is able to perceive the changes in the air of the state, guess time achieving goals is felt reaches the guessed time, via the instruction means, by operating the notification unit, an effect that the user can feel the sensation should enjoy from the air environment adjustment device Can be obtained.

  Therefore, for example, it is expected to be used not only for general houses but also for public facilities such as hospitals and nursing homes, and industrial buildings such as factories and warehouses where people are expected to stay.
