(Embodiment 1)
[Constitution]
First, the configuration of the space proposal system according to Embodiment 1 will be described. 1 is a block diagram showing a functional configuration of a space proposal system according to Embodiment 1. FIG.

The space proposal system 100 according to Embodiment 1 is a system that determines whether or not a designed space satisfies the evaluation criteria of the WELL Building Standard (registered trademark, hereinafter referred to as WELL certification). is. WELL certification is a certification program that aims to create a better living environment by adding the perspective of human health to the physical environment such as temperature, humidity, and air quality when designing spaces. WELL certification evaluation items include, for example, items related to air, items related to light, and items related to comfort. A space proposal system 100 includes a database 10 , a server device 20 and an information terminal 30 . The server device 20 includes a space design data generation unit 21 , a first acquisition unit 22 , a calculation unit 23 , a determination unit 24 and a presentation unit 25 . Each of these components is implemented by a microcomputer or processor provided in server device 20 .

[motion]
Next, the operation of the space proposal system 100 will be described. FIG. 2 is a flow chart of the operation of the space proposal system 100. As shown in FIG.

The space design data generator 21 generates space design data indicating the state of the designed space based on BIM (Building Information Modeling) data 11 and equipment data 12 provided by the database 10 (S11). The database 10 is, for example, provided by a server device other than the server device 20 , but may be provided by the server device 20 .

The BIM data 11 is data indicating the shape and dimensions (that is, the floor plan) of the building that constitutes the space, and is specifically three-dimensional CAD (Computer Aided Design) data. The BIM data 11 integrates a plurality of types of building-related data such as data related to members (materials) that constitute the building. The BIM data 11 may also include data that enables simulations of the environment inside or outside the building under various conditions.

The equipment data 12 is data indicating the specifications of the equipment arranged in the space. Equipment specifications include equipment model number, shape and size, maximum output, power supply specifications, and the like. Equipment here means equipment for adjusting the environment of the space. Specifically, equipment includes air conditioning equipment that adjusts the temperature and humidity in the space, ventilation equipment that adjusts the air flow in the space, air cleaners that adjust the concentration of particulate matter in the space, or Lighting equipment for adjusting brightness (light environment).

The space design data generation unit 21 generates a three-dimensional model of the designed space as space design data by, for example, arranging the facilities indicated by the facility data 12 in the building determined by the BIM data 11 . The space design data generation unit 21 generates space design data based on a designer's operation via a user interface device or the like included in the information terminal 30, for example.

Next, the first acquisition unit 22 acquires space design data (S12). In addition, it is not essential that the space design data is generated in the server device 20, and the first acquisition unit 22 may directly acquire the space design data from a server device other than the server device 20, or the like.

Next, the calculation unit 23 calculates the first spatial distribution (that is, three-dimensional distribution) of the environmental information in the designed space based on the space design data acquired by the first acquisition unit 22 (S13). The calculator 23 can calculate the spatial distribution using an existing analysis algorithm. The analysis algorithm used for calculating the spatial distribution is not particularly limited.

The calculation unit 23 calculates, for example, the spatial distribution of PMV (Predicted Mean Vote) in the designed space. The PMV is an index indicating the comfort of the space, and is environmental information indicating the environment of the space. PMV is an index that can be calculated using temperature, radiation temperature, humidity, airflow (wind speed), and the like. In addition, when calculating the PMV, the amount of clothing of the person in the room and the amount of work are required. may be used, or a limit value may be used.

Note that the calculation unit 23 may calculate the spatial distribution of environmental information other than PMV. Other environmental information includes temperature, humidity, airflow (wind speed), _CO2 concentration, concentration of particulate matter (such as PM2.5 or PM10), and VOC (Volatile Organic Compounds) concentration. That is, the calculator 23 may calculate the spatial distribution of these environmental information.

In addition, when calculating the spatial distribution, the initial value of the environmental information outside the space (that is, outdoors), the initial value of the environmental information in the space (that is, indoors), and the control parameters of the equipment (what kind of operation of the equipment state) is given as an analysis condition. The analysis conditions are given by the designer's operation via a user interface device provided in the information terminal 30, for example. The spatial distribution here is a spatial distribution assuming a state in which facilities such as air conditioners are operating, but may be a spatial distribution assuming a state in which the facilities are not operating.

Next, based on the spatial distribution calculated by the calculation unit 23, the determination unit 24 determines whether the environment in the designed space satisfies the determination criteria of the WELL certification evaluation items (S14). In other words, the criteria for the WELL certification evaluation items are the criteria used for real space environment certification. For example, in the evaluation item “comfort” of WELL certification, one criterion is that the PMV value is within the range of ±0.5 in 95% or more of the area in the space. Therefore, the determination unit 24 determines whether or not the spatial distribution of PMVs calculated by the calculation unit 23 satisfies this criterion.

When the judgment unit 24 judges that the environment in the designed space satisfies the judgment criteria of the WELL certification evaluation items (Yes in S14), the presentation unit 25 presents that fact (S15). Specifically, the presentation unit 25 outputs information indicating that the environment in the designed space satisfies the criteria of the WELL certification evaluation items. The output determination result information is transmitted to the information terminal 30 via, for example, a wide area communication network such as the Internet, and the information terminal 30 displays the determination result on the display screen. FIG. 3 is a diagram showing an example of a display screen indicating that the environment in the designed space satisfies the criteria for evaluation items of WELL certification.

On the other hand, when the determination unit 24 determines that the environment in the designed space does not satisfy the determination criteria of the WELL certification evaluation items (No in S14), the calculation unit 23 and the determination unit 24 The design space is optimized within the permissible range of the change (S16). In the optimization, the calculation unit 23 and the determination unit 24 change the design parameters, calculate the spatial distribution of the environmental information in the changed design space, and determine whether the calculated spatial distribution satisfies the determination criteria. The optimization of the design is attempted by repeating the determination of whether or not. The design parameter is, for example, the arrangement of air conditioners, and the calculation unit 23 and the determination unit 24 optimize the arrangement of air conditioners, for example. Design parameters are not particularly limited. Moreover, such an optimization method is just an example, and any existing algorithm may be used in the optimization.

After that, the determination unit 24 determines whether or not the environment in the optimized designed space satisfies the determination criteria of the WELL certification evaluation items (S17). When the judgment unit 24 judges that the environment in the designed space that has been optimized satisfies the judgment criteria of the WELL certification evaluation items (Yes in S17), the presentation unit 25 presents the optimum design solution (S18). . The presentation unit 25 specifically outputs the first presentation information indicating the optimum arrangement of the air conditioners. The output first presentation information is transmitted to the information terminal 30 via, for example, a wide area communication network, and the information terminal 30 displays a layout change proposal for air conditioners on the display screen based on the first presentation information. FIG. 4 is a diagram showing an example of a display screen of a layout change proposal for air conditioners. In this way, the presentation unit 25 presents, for example, the optimum solution for design change as a correction proposal for spatial design data.

On the other hand, when the judgment unit 24 judges that the environment in the optimized design space does not satisfy the judgment criteria of the evaluation items of WELL certification (No in S17), the presentation unit 25 presents a guideline for design change. (S19). In other words, the presentation unit 25 presents that a change within a predetermined allowable range cannot satisfy the criterion.

Specifically, the presentation unit 25 outputs the second presentation information indicating that replacement of the current air conditioner with another air conditioner or addition of the air conditioner is necessary. The output second presentation information is transmitted to the information terminal 30 via, for example, a wide area communication network, and the information terminal 30 displays a proposal (advice) such as replacement of the air conditioner based on the second presentation information on the display screen. to display. FIG. 5 is a diagram showing an example of a display screen for design change advice. In this way, the presenting unit 25 presents, for example, a design change guideline as a correction proposal for space design data.

As described above, the space proposal system 100 includes the first acquisition unit 22 that acquires space design data indicating the state of the space under design, and the spatial distribution of environmental information in the space under design based on the space design data. and a determination unit 24 that determines whether the environment in the designed space satisfies the criteria used for environment authentication of the real space based on the calculated spatial distribution. Prepare.

Such a space proposal system 100 can assist in designing a space that conforms to predetermined criteria (eg, criteria established for real spaces, such as criteria used for environmental certification).

Further, for example, the space proposal system 100 further includes a presentation unit 25 that presents a correction proposal for the space design data when the determination unit 24 determines that the environment in the designed space does not satisfy the determination criteria.

Such a space proposal system 100 can support the design of a space that conforms to a predetermined standard by presenting a correction proposal for space design data.

Further, for example, the space design data includes facility data regarding facilities for adjusting the environment, which are arranged in the designed space. The presentation unit 25 presents a layout change of equipment in the designed space as a correction proposal for the space design data.

(Embodiment 2)
[Constitution]
Next, the configuration of the space proposal system according to Embodiment 2 will be described. FIG. 6 is a block diagram showing the functional configuration of the space proposal system according to Embodiment 2. As shown in FIG.

The space proposal system 100a according to Embodiment 2 is based on suitable space design data, which is space design data for a designed space that has been determined to satisfy the WELL certification criteria. This is a system that proposes a method of controlling equipment in a space inside an object (hereinafter referred to as a real space 40). The space proposal system 100 a includes a database 10 , a server device 20 a, an information terminal 30 and a cause analysis database 50 .

The server device 20 a includes a space design data generation unit 21 , a first acquisition unit 22 , a calculation unit 23 , a determination unit 24 , a second acquisition unit 26 and an output unit 27 . Each of these components is implemented by a microcomputer or processor provided in server device 20a.

FIG. 6 also shows a plurality of sensors 41, an air conditioner 42, and a control device 43 installed in the real space 40. As shown in FIG. The space proposal system 100a may further include these components.

The sensor 41 includes a semiconductor gas sensor capable of sensing gas concentration, a temperature sensor, a humidity sensor, an airflow sensor, an illuminance sensor, a motion sensor, a microphone, a camera, and the like. Specifically, the gas concentration is CO ₂ concentration, particulate matter concentration, or VOC concentration. For example, a plurality of sensors 41 are installed in the real space 40, but at least one should be installed. The multiple sensors 41 are installed at different positions in the real space 40 . The sensor 41 may include a biosensor that senses biometric information of a person staying in the real space 40 .

The air conditioner 42 is an example of equipment installed in the real space 40 for adjusting the environment in the real space 40 . In Embodiment 2, an example in which control parameters for the air conditioner 42 are proposed will be described, but equipment for adjusting the environment in the real space 40 is not limited to the air conditioner 42 . Other examples of equipment for adjusting the environment in the real space 40 include ventilation equipment, air cleaners, lighting equipment, and the like.

The control device 43 is a device that controls equipment installed in the real space 40 . The control device 43 also functions as a gateway device that transmits the measured value of the sensor 41 to the server device 20a. The control device 43 is, for example, an EMS (Energy Management System) controller having an energy management function. The control device 43 is not limited to an EMS controller, and may be another controller that does not have an energy management function, or a gateway device.

[motion]
Next, the operation of the space proposal system 100a will be described. FIG. 7 is a flow chart of the operation of the space proposal system 100a.

As described above, the real space 40 is a space constructed based on the appropriate space design data, which is the space design data of the designed space determined by the determining unit 24 to satisfy the criteria. The second acquisition unit 26 acquires the actual measurement values of the environment information in such a real space 40 (S21). Specifically, the second acquisition unit 26 acquires the measured values of the plurality of sensors 41 via the control device 43 . The second acquisition unit 26 also acquires the operating state (set temperature, air volume, etc.) of the air conditioner 42 in the real space 40 .

The second acquisition unit 26 may directly acquire the measured values of the PMV calculated by the server device 20a or an external device (that is, the PMV calculated based on the measured temperature, humidity, airflow, etc.). In the following description, it is assumed that the measured value of PMV is acquired in step S21.

Next, the calculation unit 23 calculates the spatial distribution of design (that is, simulation) environment information (specifically, PMV) based on the suitable space design data that is the basis for constructing the real space 40. is calculated (S22). This spatial distribution is calculated by matching analysis conditions to the actual state of the current real space 40 (such as the operating state of equipment) as much as possible.

Next, the output unit 27 compares the measured PMV value obtained in step S21 with the spatial distribution of the PMV calculated in step S22, and compares the measured PMV value obtained in step S21 with the corresponding The cause of the difference from the design PMV value (hereinafter also referred to as the PMV design value) is analyzed (S23). Specifically, the output unit 27 specifies the position (coordinates) where the PMV is actually measured in the real space 40, and uses the PMV value at the specified position in the PMV spatial distribution as the design value of the PMV to perform cause analysis. conduct.

This cause analysis is performed, for example, by referring to a cause analysis database 50 constructed in advance. In the causal analysis data 51 provided by the causal analysis database 50, the difference between the measured PMV value and the designed PMV value is associated with the cause of such a difference. Such a cause analysis database 50 is empirically or experimentally created in advance. Also, the cause analysis database 50 is updated by accumulating data. Then, the output unit 27 generates control parameters (set temperature, air volume, air direction, etc.) of the air conditioner 42 for bringing the actual measured value of the PMV closer to the design value based on the analysis result of the cause (S24). It should be noted that the use of the cause analysis database 50 is not essential.

The calculation unit 23 recalculates the PMV spatial distribution using the generated control parameters (S25), and the determination unit 24 determines whether the recalculated PMV spatial distribution satisfies the determination criteria of the WELL certification evaluation items. (S26). That is, the determination unit 24 determines whether the control parameters generated in step S25 are configured so that the designed space satisfies the criteria of the evaluation items of WELL certification (whether the simulation is OK). In this way, the space proposal system 100a does not simply determine whether or not the measured value of the environmental information at a specific position in the real space 40 satisfies the criterion, but rather the distribution of the environmental information in the designed space (that is, space) satisfies the criterion.

When the determination unit 24 determines that the recalculated first spatial distribution does not satisfy the determination criteria of the WELL certification evaluation item (No in S26), the output unit 27 does not output the control information indicating this control parameter. Instead, another control parameter is generated again (S24).

On the other hand, when the determination unit 24 determines that the recalculated PMV spatial distribution satisfies the determination criteria of the WELL authentication evaluation item (Yes in S26), the output unit 27 outputs control information indicating this control parameter. (S27). The output control information is transmitted to the information terminal 30 via, for example, a wide area communication network, and the information terminal 30 displays the control parameters on the display screen based on the control information. FIG. 8 is a diagram showing an example of a control parameter display screen.

The output control information is also transmitted to the control device 43 via, for example, a wide area communication network, and the control device 43 controls the air conditioner 42 using the control parameters indicated by the received control information (S28). . After that, by repeating the processing of steps S21 to S28, the measured value of PMV approaches the design value.

[Effects, etc.]
As described above, the space proposal system 100a includes the first acquisition unit 22 that acquires the space design data indicating the state of the designed space, and the space design data (the space design data includes: (including equipment data related to equipment for adjusting the environment in which the A determination unit 24 that determines whether the environment in the designed space satisfies the criteria used for environment authentication of the real space 40, and the designed space determined by the determination unit 24 to satisfy the criteria. A second acquisition unit 26 that acquires the measured values of the environmental information in the real space 40 constructed based on the suitable space design data, which is the spatial design data of the suitable space design data and an output unit 27 for outputting control information indicating a control method for the equipment arranged in the real space 40 in order to approach the design value determined by the spatial distribution calculated based on the above.

Such a space proposal system 100a can propose a facility control method (for example, control parameters) for bringing the real space 40 closer to a space that satisfies the criteria used for environment authentication.

Also, for example, the output unit 27 outputs the control information to the control device 43 that controls the equipment arranged in the real space 40 .

Such a space proposal system 100a can control equipment to make the real space 40 closer to a space that satisfies the criteria used for environment authentication.

Further, for example, the output unit 27 generates control information based on the difference between the actually measured value and the design value of the acquired environmental information, and the spatial distribution recalculated using the generated control information satisfies the criterion. When it is determined that, the control information is output.

Such a space proposal system 100a can propose a control method that has been confirmed to make the real space 40 into a space that satisfies the criteria used for environment authentication.
