However, the energy consuming device 15 is not necessarily limited thereto, and any device capable of consuming energy may be added, and various other devices may be added. For example, a humidifier, a lighting device, an electric fan, a dehumidifier, etc. may be further added as an energy consuming device.

In addition, the building energy management system 100 is a building from a plurality of internal sensors 11 provided in each interior room 10 in order to obtain building information for each interior room 10 from each interior room 10 of the building. Information can be obtained.

Here, as an example, the plurality of internal sensors 11 provided in each interior room 10 are a temperature sensor 11a that senses the temperature of the interior room, as shown in FIG. 2, and access detection that detects the number of occupants in the interior room. It may include at least one of a sensor 11b, a humidity sensor 11c that senses humidity in the inner room, and a carbon dioxide sensor 11d that can measure a carbon dioxide concentration in the inner room.

In addition, through the user of each interior room 10, the building energy management system 100 can obtain schedule information for knowing the number of rooms occupied by time slot for each interior room 10, as shown separately in FIG. Although not, a module capable of calculating the energy consumption of the building is separately provided in the control unit 110 to obtain the energy consumption information of the building as the building information.

Therefore, the system according to the present invention provides at least one of the temperature, the number of occupants, the number of occupants per time slot, the carbon dioxide concentration, or the energy consumption information of the building as building information for each interior room 10 inside the building. I can receive it.

In addition, the building energy management system 100 is electrically connected to a plurality of external sensors 13 provided on a roof of a building or an outer wall of a building in order to obtain atmospheric information outside the building, and the plurality of external sensors 13 Air quality information can be obtained from.

Therefore, the building energy management system 100 of the present invention has a fine dust concentration of 10 μm or less (PM10), an ultrafine dust concentration of 2.5 μm or less (PM2.5), nitrogen dioxide concentration, sulfur dioxide concentration, carbon monoxide concentration, and ozone concentration. At least one of them may be provided as waiting information.

In addition, the building energy management system 100 may be linked with a server of an external organization that provides weather information. The building energy management system 100 may receive at least one of information on temperature, humidity, and rainfall for an area in which the building is located from the outside as weather information.

The building energy management system 100 according to an example of the present invention may include a control unit 110, a database unit 120, an input interface 130, and an output interface 140, as shown in FIG. 2. .

The database unit 120 may store weather information, atmospheric information, and data on building information collected by the building energy management system 100, and each input by a user through an input interface 130 such as a keyboard and a mouse. Schedule information for the inner room 10 may be stored.

Here, as the energy consumption pattern information of the building, the energy consumption pattern information of the building may be calculated by calculating the energy consumption amount of the building for each time period within the control unit 110.

Such energy consumption pattern information may include information on power, gas, or district heating consumed in a building.

In order to predict the energy consumption of the building, the prediction module 113 includes building information including information on energy consumption patterns, indoor temperature, and indoor humidity, which is information on past building energy consumption, and outdoor temperature, outdoor humidity, and rainfall. At least one of fine dust concentration (PM10), ultrafine dust concentration (PM2.5), nitrogen dioxide concentration, sulfur dioxide concentration, carbon monoxide concentration, and ozone concentration is added to the prediction model using meteorological information including, etc. Predictive information can be calculated.

Accordingly, the building energy management system 100 according to an exemplary embodiment of the present invention, as shown in FIG. 3, collects the weather information, the building information, and the atmosphere information by the collection module 111, The prediction module 113 may generate more sophisticated prediction information reflecting the fluctuation of the load of the device such as the air purifier 15b and the decrease in the efficiency of the cooling/heating device 15a due to fine dust. Through this, the driving control module 115 ) Through the control of the driving of the various energy consuming devices 15 provided in the building, it is possible to more efficiently operate the energy use for the building.

The building energy management system 100 according to an example of the present invention may have different operating methods during night time and day time, as an example. This will be described in more detail with reference to FIGS. 4 to 7 as follows.

FIG. 4 is a diagram for explaining an example of a method of operating the building energy management system 100 according to an example of the present invention during night time, and FIG. 5 is a diagram for explaining an example of a change to the operation method described in FIG. 4. It is a degree.

6 is a diagram for explaining an example of a method of operating the building energy management system 100 according to an example of the present invention during the daytime, and FIG. 7 is a diagram for explaining an example of a change to the operation method described in FIG. It is a degree.

The building energy management system 100 according to an example of the present invention uses building information, atmospheric information, and weather information to consider the indoor temperature of the building and the concentration of external fine dust during the night time, and carbon dioxide in the interior of the building during the daytime. In consideration of the concentration and the external fine dust concentration, it is possible to control the operation of the energy consuming device 15 of the building, for example, the ventilation facility 15c.

Here, the night time may be a time from sunset time to sunrise time, and the daytime time may be a time from sunrise time to sunset time, but the present invention is not necessarily limited thereto, and night time and daytime time are building managers. It is also possible to set separately by.

As an example, as shown in FIG. 4, the building energy management system 100 according to an example of the present invention has a higher indoor temperature inside the building than the outdoor temperature outside the building during night time (S11), and the external fine dust concentration Only when is smaller than the first fine dust reference value (S12), the ventilation facility 15c for the entire building may be operated (S13).

For example, the external fine dust may be fine dust (PM10) or ultra-fine dust (PM2.5), and the first fine dust reference value is 60 ㎍ of the concentration of fine dust (PM10) or ultra-fine dust (PM2.5) May be the case /m³.

In this way, during nighttime, especially in summer, the temperature inside the building is relatively high, so when the outside fine dust is not serious, the inside of the building is ventilated with outside air to reduce the temperature inside the building to a minimum. You can make the interior of the building more comfortable while lowering it by using.

However, when the indoor temperature of the building is not higher than the outdoor temperature or the external fine dust reference value is not lower than the first fine dust reference value, the ventilation facility 15c for the entire building may not be operated (S14).

Accordingly, according to the present invention, when the internal temperature of the building is not high or the air quality is poor, ventilation is not performed, thereby minimizing the energy consumption of the building.

The present invention is a modification to FIG. 4, and when the ventilation equipment 15c is provided for each inner room 10, each of the ventilation equipment 15c of each inner room 10 may be controlled.

As an example, as shown in FIG. 5, the indoor temperature is higher than the outdoor temperature in at least one of the inner rooms 10 of the building at night time (S11'), and the fine dust concentration or ultrafine dust according to atmospheric information When the concentration of is lower than the first fine dust reference value (eg, 60 μg/m³) (S12), the driving control module 115 provides ventilation equipment 15c for at least one interior room having a high room temperature among the plurality of interior rooms. It can be operated (S13').

However, when the indoor temperature inside the building is high and the external fine dust concentration is higher than the first fine dust reference value, the ventilation equipment 15c for at least one interior room is not operated, and the air purifier 15b and the air conditioner are operated ( S15) You can do it.

In addition, during the daytime, as shown in FIG. 6, in at least one of the inner rooms 10 of the building, the indoor carbon dioxide concentration is higher than the carbon dioxide reference value, for example, 1000 ppm (S21), When the dust concentration or the concentration of the ultrafine dust is lower than the second fine dust reference value (for example, 120 μg/m³) (S22), the drive control module 115 according to the present invention is a ventilation facility 15c for the entire building. Can be operated (S23).

However, when the indoor carbon dioxide concentration is lower than the carbon dioxide standard value, or the fine dust concentration or ultra-fine dust concentration according to atmospheric information is higher than the second fine dust standard value (for example, 120 ㎍/m³), ventilation for the entire building The facility 15c may not be operated (S24).

In this way, when the outside air quality is good and the carbon dioxide concentration inside the building is high, by operating the pipes for the entire building, the inside of the building can be operated more comfortably at a lower energy cost.

In addition, when the ventilation equipment 15c for each interior room 10 is provided, as shown in FIG. 7, the indoor carbon dioxide concentration is higher than the carbon dioxide reference value in at least one interior room of each interior room 10 of the building ( S21), when the fine dust concentration or the ultrafine dust concentration according to the atmospheric information is lower than the second fine dust reference value (S22), the drive control module 115 according to the present invention does not operate the ventilation facility for the entire building. , The ventilation facility 15c may be operated (S23') only for at least one inner room, that is, an inner room having a relatively high carbon dioxide concentration.

In addition, when the indoor carbon dioxide concentration in at least one inner room is higher than the carbon dioxide reference value, but the fine dust concentration or the ultrafine dust concentration according to the atmospheric information is higher than the second fine dust reference value, the driving control module 115 The air purifier 15b can be operated (S25) without operating the ventilation equipment 15c for the inner room.

Accordingly, while minimizing the amount of energy consumption of the building, it is possible to selectively make only the relatively uncomfortable inner rooms among the inner rooms 10 inside the building.

Such a building energy management system 100 may operate a building in consideration of the peak power reference value set in the building.

8 is a diagram for explaining an example of a method in which the building energy management system 100 according to an example of the present invention is operated in consideration of a peak power reference value, and FIG. 9 is a view showing a modification of the operation method described in FIG. 8. It is a diagram for explanation.

As shown in FIG. 8, in at least one of the inner rooms 10 of the building, the indoor carbon dioxide concentration is higher than the carbon dioxide reference value (S31), and the current used power among the energy consumption of the building is the peak power reference value set in the building. When it exceeds (S32), the drive control module 115 stops the operation of the cooling and heating device (15a) provided in at least one interior room, and then the ventilation equipment (15c) or the air cleaner (15b) for at least one interior room. ) Can be operated (S33).

However, the present invention is not necessarily limited thereto, and when the current power consumption exceeds the peak power reference value (S32), after stopping the cooling and heating operation of the entire building, ventilation equipment 15c or air for at least one interior room When the purifier 15b is operated (S33) and the degree of comfort for the interior room is equal to or higher than the set level, it is also possible to operate the cooling and heating of the entire building back to its original state.

In addition, when the current use power is lower than the peak power reference value, the heating and cooling device 15a and the ventilation facility 15c or the air cleaner 15b provided in at least one interior room may be simultaneously operated.

Accordingly, the building energy management system 100 according to the present invention can operate the interior of the building more comfortably while appropriately optimizing the current used power of the building so as not to exceed the peak power reference value.

In addition, as shown in FIG. 9, the present invention may operate energy use for a building in consideration of the number of occupants in each interior room 10 provided in the building.

More specifically, as shown in FIG. 9, in at least one of the inner rooms 10 of the building, the indoor carbon dioxide concentration is higher than the carbon dioxide reference value (S41), and the current used power among the energy consumption of the building is set in the building. In a state in which the peak power reference value is exceeded (S42), when there is an internal room in which the number of occupants is greater than the minimum occupancy reference value among at least one interior room 10 (S43), the driving control module 115 The operation of the air conditioner 15a may be stopped, and the ventilation equipment 15c or the air cleaner 15b may be sequentially operated (S45) from an inner room larger than the minimum occupancy reference value among at least one inner room.

That is, in the present invention, the ventilation facility 15c or the air cleaner 15b may be operated with priority from the inner room in which the number of occupants is greater than the minimum occupancy reference value among at least one inner room having a high carbon dioxide concentration.

Or, using the prediction information generated by the prediction module 113, within a range in which the current power consumption of the building does not increase, the number of occupants among the at least one cabin with a high carbon dioxide concentration is the rest of the room except for the interior room whose occupancy is greater than the minimum occupancy reference value. It is also possible to stop the operation of the air conditioner 15a only for the inner room, and to operate the ventilation equipment 15c or the air cleaner 15b with priority from the inner room where the occupants are larger than the minimum occupancy reference value.

Accordingly, while maintaining the comfort of building users who use the inner room where the number of occupants is larger than the minimum occupancy standard value, the number of occupants is lower than the minimum occupancy standard value, and ventilation is set as a lower priority for the virtually vacant inner room, thereby using the energy of the building. While optimizing, you can create a more comfortable interior environment.

That is, the present invention takes into account the peak power standard value among the inner rooms of the inner rooms with high carbon dioxide concentration, and the number of occupants is higher than the minimum occupancy criterion rather than the empty inner rooms because there are few occupants, and preferentially and sequentially ventilate from inner rooms with many users By operating the facility 15c or the air purifier 15b, it is possible to selectively operate the building's energy management system for an interior room where substantially comfort is required.

In addition, even if the carbon dioxide concentration in the inner room is substantially higher than the carbon dioxide standard value, in the case of rooms where there are no users or very small occupants below the minimum occupancy standard value, the air conditioner 15a, ventilation equipment 15c, or air cleaner 15b By stopping the operation of the building, it is possible to minimize the energy consumption of the building.

10 is an example of schedule information used in the present invention, and FIG. 11 is a diagram for explaining an example of the invention in which the building energy management system 100 according to an example of the present invention operates in consideration of the schedule information of FIG. 10 , FIG. 12 is a diagram for explaining a modification example of the operation method described in FIG. 12.

In the building energy management system 100 of the present invention, the building information may further include schedule information for knowing the number of occupants per time slot for each interior room 10 inside the building.

For example, when the building is a school and each inner room 10 is a class, an auditorium, a teacher's office, or a music room, the schedule information may be a timetable for each class, as shown in FIG. 10.

Such a timetable can identify the number of occupants in the class. In other words, for general subjects that are not arts and sports such as music, art, and physical education, the schedule is performed in the corresponding internal room, and the number of occupants in one class is larger than the minimum occupancy standard, and most are occupied by the maximum. When performed in an arts and sports classroom, for example, a music room, an art room, or an auditorium or a playground, the number of occupants in the class may be less than the minimum occupancy standard.

In consideration of these points, it is possible to estimate the number of people in the room in the future from the schedule information, and by using this, it is possible to more effectively manage the energy use of the building.

As an example, the schedule information shown in FIG. 10 is schedule information used in the first room,

(1) Time zone before the 1st time zone: Tuesday 1st class, schedule-math, schedule execution place-1st inner room, (2) 1st time zone: Tuesday 2nd class, schedule-② music, schedule performance place-music room, (3 ) Time zones after the 1st time zone: 3 lessons on Tuesday, schedule-Korean, place to perform the schedule-in the case of the 1st room,

For example, as shown in FIG. 11, the number of occupants in the first time zone (Tuesday 2 class) from the previous time zone of the first time zone (Tuesday 1 class) is higher than the carbon dioxide reference value (S51) and schedule information If the number of occupants is lower than the minimum occupancy standard value, but the occupancy of the first time zone (Tuesday 3 hours) is higher than the minimum occupancy standard value (S52), the drive control module 115 is a ventilation facility for the first interior room during the first time zone. (15c) Or the air cleaner 15b can be operated (S53).

Accordingly, with respect to the interior room in which the comfort level of the interior room is deteriorated, the building can be operated more effectively by ventilating the interior room during a time period when there are few users of the interior room.

In addition, when the first time zone is a general subject other than an arts and sports class, the number of occupants in the first room may not change. In this case, the drive control module 115 does not wait until the first time zone, but During the previous time period, the ventilation facility 15c or the air purifier 15b for the first interior room may be operated (S55).

For example, if the time zone before the 1st time zone is Wednesday 1st class-English, the 1st time zone is Wednesday 2nd class-Korean, and the time zone after the 1st time zone is Wednesday 3rd class-Physical, carbon dioxide in the 1st room from English time of 1st class If the concentration is high and there is virtually no change in the number of occupants in the first inner room, the ventilation facility 15c or the air cleaner 15b for the first inner room should be operated immediately during the first period, without having to wait until the second period, which is the first time slot. I can.

In addition, according to the present invention, not only the schedule information described in FIG. 11 but also the energy consumption pattern information of the building can be used to more effectively operate the energy use of the building.

As an example, as shown in FIG. 12, the energy consumption pattern information in the first time zone is greater than the peak power reference value (S61), the number of occupants during the first time zone is smaller than the minimum occupancy reference value, and stayed in for a time zone after the first time zone. When the number of personnel is greater than the minimum occupancy reference value (S52), considering that the power is at the peak time, the driving control module 115 stops the operation of the air conditioner 15a for the first interior room during the first time period, and the ventilation facility 15c ) Or the air cleaner 15b may be operated (S53').

Specifically, in the present invention, it is possible to know whether the power consumption in the first time period exceeds the peak power reference value through the energy consumption pattern information and the schedule information.

As an example, in FIG. 10, the concentration of carbon dioxide exceeds the reference value from the biological time at 5th Wednesday, which is a time zone before the first time zone, and according to the energy consumption pattern information, the first time zone corresponds to the power peak time zone, and in the first time zone When the number of occupants in the first interior room decreases and the number of occupants in the first interior room increases after the first time period, the drive control module 115 performs the first time during the first time period when the first interior room is empty (6 lessons on Wednesday). It is possible to stop the operation of the air conditioner 15a for the inner room, and operate the ventilation equipment 15c or the air cleaner 15b.

As described above, the building energy management system 100 according to an example of the present invention uses the predicted information on the energy consumption of the building in the building information, such as atmospheric information, weather information, and occupants for fine dust, etc., and uses the energy of the building. Can be operated more efficiently.

In addition, the description of the operation of the above-described building energy management system is an example, and the present invention is not necessarily limited thereto, and each operation of the building energy management system has been described separately for each embodiment. It is not executed as, and may be merged and mixed with each other unless they are compatible with each other.

The present invention is not limited to the above-described embodiments and the accompanying drawings, and various modifications and variations are possible from the perspective of those of ordinary skill in the field to which the present invention pertains. Therefore, the scope of the present invention should be defined by the claims of the present specification as well as those equivalents to the claims.
