Background Art

[0002] Patent Document 1 describes a renewal support system that proposes replacement of equipment installed in a building. In the technique described in Patent Document 1, existing fixtures are estimated based on three-dimensional space information received by the renewal support system from a measuring device. Patent Document 1 describes an example in which the equipment to be replaced is a lighting fixture. Further, Patent Document 1 describes an example in which when selecting a candidate for a new lighting fixture to replace an existing lighting fixture, among lighting fixtures having the same or higher efficiency and functions as the existing lighting fixture, the lighting fixture with the minimum initial cost is selected as the new lighting fixture. Furthermore, Patent Document 1 describes an example in which a simulation of the light environment of a room is performed using the information created by the renewal support system. Also, Patent Document describes an example of obtaining the electricity cost when a new lighting fixture is used.

[0003] By the way, the initial cost when introducing a lighting control system including lighting fixtures varies depending on the control method of the lighting fixtures. However, in the technique described in Patent Document 1, when calculating the initial cost and the like, the control method of the lighting fixtures is not considered. Therefore, with the technique described in Patent Document 1, the initial cost when introducing a lighting control system cannot be appropriately calculated, and the design of the lighting control system cannot be appropriately supported.

[0011] <First Embodiment> The following describes a first embodiment of the lighting control design support system, lighting control design support method, and program of the present invention.

[0012] Figure 1 shows an example of the lighting control design support system 1 of the first embodiment. More specifically, Figure 1(A) shows an example of the lighting control design support system 1 of the first embodiment, and Figure 1(B) shows an example of a lighting control system LC that is the target of design support by the lighting control design support system 1 of the first embodiment. In the example shown in Figure 1, the lighting control system LC includes a lighting fixture LC1, a control device LC2 for controlling the lighting fixture LC1, a sensor LC3 used for controlling the lighting fixture LC1 by the control device LC2, and a distribution board LC4 connected to the lighting fixture LC1. The lighting control design support system 1 of the first embodiment assists the designer of the lighting control system LC in designing the lighting control system LC. The lighting control design support system 1 includes an acquisition unit 11 and a calculation unit 12. In the example shown in Figure 1, the lighting control system LC that is the target of design support by the lighting control design support system 1 includes a sensor LC3 used to control the lighting fixture LC1 by the control device LC2. However, in other examples (for example, in examples where scheduled control is applied), the lighting control system LC that is the target of design support by the lighting control design support system 1 does not need to include the sensor LC3.

[0013] The acquisition unit 11 acquires information (a part of the "input items", "memory items", and "calculated items" calculated by the calculation unit 12, which will be described later) used in the design of the lighting control system LC. The information acquired by the acquisition unit 11 includes, for example, information for calculating the initial cost H1 when the lighting control system LC is introduced, information for calculating the annual power usage fee J6 when the lighting control system LC is introduced, and information for calculating the annual power usage fee I5 when the lighting control system LC is not introduced. The information for calculating the initial cost H1 when the lighting control system LC is introduced includes the number B6 of lighting fixtures LC1, the cost F2 per lighting fixture LC1, the cost B7 of the control device LC2, the cost related to the distribution board LC4, the construction cost G4 of the lighting control system LC, and the like. The information for calculating the annual power usage fee J6 when the lighting control system LC is introduced includes the power consumption J1 per lighting fixture LC1, the usage time J2 of the lighting fixture LC1, the power usage fee unit price J3, and the reduction rate J4 indicating the ratio of the power usage amount by the lighting fixture LC1 when the lighting control system LC is introduced to the power usage amount by the non-controlled lighting fixture LE, which is the lighting fixture used when the lighting control system LC is not introduced. The information for calculating the annual power usage fee I5 when the lighting control system LC is not introduced includes the power consumption I1 per non-controlled lighting fixture LE, the usage time I2 of the non-controlled lighting fixture LE, the power usage fee unit price I3, and the like.

[0014] The calculation unit 12 calculates calculation items from the information (input items, storage items, and a part of the calculation items) acquired by the acquisition unit 11. The calculation unit 12 includes a control method selection unit 12A, an equipment quantity cost calculation unit 12B, a system engineer cost calculation unit 12C, a distribution board design equipment cost calculation unit 12D, a control system cost calculation unit 12E, a lighting fixture cost difference calculation unit 12F, a construction cost calculation unit 12G, an initial cost calculation unit 12H, a first electricity usage charge calculation unit 12I, a second electricity usage charge calculation unit 12J, a first initial cost recovery required years calculation unit 12K, an energy saving amount calculation unit 12L, a greenhouse gas reduction amount calculation unit 12M, a second initial cost recovery required years calculation unit 12N, and a system configuration diagram creation unit 12P. The control method selection unit 12A selects a control method A6 for the lighting fixture LC1 by the control device LC2. As will be described in detail later, in order to assist the designer of the lighting control system LC in designing the lighting control system LC, the lighting control design support system 1 performs simulations such as the initial cost H1 of the lighting control system LC and the annual electricity usage charge J6 when the lighting fixture LC1 is controlled by the control device LC2 with the control method A6 selected by the control method selection unit 12A.

[0015] FIG. 2 is a diagram showing an example of a map A5 used for the selection of the control method A6 for the lighting fixture LC1 by the control method selection unit 12A. In the example shown in Figure 2, the control method selection unit 12A selects the control method A6 for lighting fixture LC1 based on the following inputs from the designer of the lighting control system LC to the lighting control design support system 1: A1 (whether the lighting control system LC needs to cooperate with the security system), A2 (whether the lighting control system LC needs to cooperate with the disaster prevention system), A3 (whether the lighting control system LC needs to cooperate with the air conditioning management system), A4 (whether the lighting control system LC needs to cooperate with the air conditioning demand control system), and the map A5 shown in Figure 2. The security system, disaster prevention system, air conditioning management system, and air conditioning demand control system are systems different from the lighting control system LC. The control method A6 for lighting fixture LC1 selected by the control method selection unit 12A includes the high-function control method A61, the PLC (Power Line Communication) control method A62, the wireless control method A63, and the two-wire control method A64.

[0021] When the control method selection unit 12A selects PLC control method A62 as the control method A6 for lighting fixture LC1, the lighting control system LC can be linked with the air conditioning demand control system. In one example where the control method selection unit 12A selects PLC control method A62 as the control method A6 for lighting fixture LC1, the control device LC2 controls lighting fixture LC1 using power line communication by employing technology similar to that described on the website shown at the URL below. https: / / monoist.itmedia.co.jp / mn / articles / 2004 / 21 / news080.html

[0025] In another example where the control method selection unit 12A selects the two-wire control method A64 as the control method A6 for the lighting fixture LC1, the control device LC2 controls the lighting fixture LC1 using a two-wire multiplex transmission method, for example, by using a technology similar to the technology described on the website shown at the URL below. https: / / www2.panasonic.biz / jp / densetsu / bs / lighting_control / full2 / transmission /

[0026] In the example shown in Figure 2, the lighting control design support system 1 receives inputs from the designer of the lighting control system LC regarding the necessity of linking with a security system (A1), the necessity of linking with a disaster prevention system (A2), the necessity of linking with an air conditioning management system (A3), and the necessity of linking with an air conditioning demand control system (A4). In other words, the necessity of linking with a security system (A1), the necessity of linking with a disaster prevention system (A2), the necessity of linking with an air conditioning management system (A3), and the necessity of linking with an air conditioning demand control system (A4) are input items and are acquired by the acquisition unit 11. Map A5, shown in Figure 2, is stored as a memory item either inside or outside the lighting control design support system 1 and is acquired by the acquisition unit 11. When the control method selection unit 12A selects one of several control methods from among the high-function control method A61, PLC control method A62, wireless control method A63, and two-wire control method A64 as the control method A6 for the lighting fixture LC1 by the control device LC2, the lighting control design support system 1 performs simulations of the initial cost H1 of the lighting control system LC, the annual electricity usage fee J6, etc. for each of the multiple control methods.

[0027] In the example shown in Figure 1, the equipment cost calculation unit 12B calculates the number of control devices LC2 that control the lighting fixtures LC1, B6 (calculation item), based on the number of lighting fixtures LC1 B1, the necessity of motion control B2, the necessity of illumination control B3, the necessity of schedule control B4, and a predetermined relational expression B5. The number of control devices LC2 B6 calculated by the equipment cost calculation unit 12B includes the number of remote control relays, which will be described later. The lighting control design support system 1 accepts inputs from the designer of the lighting control system LC, including the number of lighting fixtures LC1 (B1), whether motion control is required (B2), whether illuminance control is required (B3), and whether schedule control is required (B4). In other words, the number of lighting fixtures LC1 (B1), whether motion control is required (B2), whether illuminance control is required (B3), and whether schedule control is required (B4) are input items and are acquired by the acquisition unit 11. The relational expression B5 is stored as a memory item either internally or externally within the lighting control design support system 1 and is retrieved by the acquisition unit 11. Furthermore, the equipment cost calculation unit 12B calculates the cost B7 (calculation item) of the control equipment LC2 that controls the lighting fixtures LC1, based on the number of lighting fixtures LC1 B1, the necessity of motion control B2, the necessity of illumination control B3, the necessity of schedule control B4, and the relational formula B5. Furthermore, the equipment cost calculation unit 12B calculates the number of sensors LC3 used to control the lighting fixtures LC1, B8 (calculation item), based on the number of lighting fixtures LC1, B2 whether motion control is required, B3 whether illumination control is required, B4 whether schedule control is required, and the relational formula B5. Furthermore, the equipment cost calculation unit 12B calculates the cost B9 (calculation item) of the sensor LC3 used to control the lighting fixture LC1, based on the number of lighting fixtures LC1 B1, the necessity of motion control B2, the necessity of illumination control B3, the necessity of schedule control B4, and the relational formula B5.

[0028] In one example of relational equation B5, when the control method A6 of lighting fixture LC1 by control device LC2 is PLC control method A62, the device cost calculation unit 12B calculates the number of control devices LC2 as B6, which is "the number of master units (= 1 unit per building where the lighting control system LC is installed (per property))" and "the number of control slave units (= the number of lighting fixtures LC1 B1 divided by 5)", and calculates the cost of control devices LC2 as B7, which is "the cost of the master unit (for example, 300,000 yen per building where the lighting control system LC is installed (per property))" and "the cost of the control slave units (for example, 30,000 yen / unit × 40 units = 1,200,000 yen)".

[0029] If the Lighting Control Design Support System 1 receives input indicating that motion control is not required (B2), the Equipment Cost Calculation Unit 12B calculates the number of motion sensors as "0" (B8) and the cost of the motion sensors as "0 yen" (B9). If the Lighting Control Design Support System 1 receives input indicating that motion control is required (B2), the Equipment Cost Calculation Unit 12B calculates the number of sensors as B8 by dividing the number of lighting fixtures as B1 by the number of lighting fixtures as B1 that can be handled by one motion sensor (for example, 20), and calculates the cost of the sensors as B9 by multiplying the number of motion sensors by the cost per motion sensor (for example, 50,000 yen / unit). If the Lighting Control Design Support System 1 receives input indicating that illuminance control is not required (B3), the Equipment Cost Calculation Unit 12B calculates the number of illuminance sensors as "0" (B8) and the cost of illuminance sensors as "0 yen" (B9). If the Lighting Control Design Support System 1 receives input indicating that illuminance control is required (B3), the Equipment Cost Calculation Unit 12B calculates the number of illuminance sensors as B8 by dividing the number of lighting fixtures LC1 by the number of lighting fixtures LC1 that can be handled by one illuminance sensor (for example, 20), and calculates the cost of illuminance sensors as B9 by multiplying the number of illuminance sensors by the cost per illuminance sensor (for example, 50,000 yen / unit). For motion-activated and illumination-controlled systems, control is performed using technologies similar to those described on the website at the URL below. https: / / www.jlma.or.jp / information / 220315cutback.pdf

[0030] If the Lighting Control Design Support System 1 receives input indicating that schedule control is not required (as B4), the Equipment Cost Calculation Unit 12B calculates "0 units" as the number of sensors LC3 (B8) and "0 yen" as the cost of sensors LC3 (B9). Similarly, if the Lighting Control Design Support System 1 receives input indicating that schedule control is required (as B4), the Equipment Cost Calculation Unit 12B calculates "0 units" as the number of sensors LC3 (B8) and "0 yen" as the cost of sensors LC3 (B9). Schedule control uses technologies similar to those described on the website indicated at the following URL. https: / / www.jlma.or.jp / information / 220315cutback.pdf

[0031] Relational equation B5 is similar to the relationship between the number of lighting fixtures LC1 B1, the necessity of motion control B2, the necessity of illuminance control B3, and the necessity of schedule control B4 when the control method A6 of lighting fixtures LC1 by the control device LC2 is the PLC control method A62, and the number of control devices LC2 that control lighting fixtures LC1 B6 when the control method A6 of lighting fixtures LC1 by the control device LC2 is the high-function control method A61, and the number of control devices LC2 that control lighting fixtures LC1 B6 This includes the relationship between the number of lighting fixtures LC1 B1, the necessity of motion sensor control B2, the necessity of illuminance control B3, and the necessity of schedule control B4 when the control method A6 of lighting fixture LC1 by control device LC2 is wireless control method A63, and the relationship between the number of lighting fixtures LC1 B1, the necessity of motion sensor control B2, the necessity of illuminance control B3, and the necessity of schedule control B4 when the control method A6 of lighting fixture LC1 by control device LC2 is two-wire control method A64, and the relationship between the number of lighting fixtures LC1 B1, the necessity of motion sensor control B2, the necessity of illuminance control B3, and the necessity of schedule control B4, and the number of control devices LC2 that control lighting fixture LC1.

[0032] Furthermore, equation B5 includes the same relationship as above when the control method A6 of lighting fixtures LC1 by control device LC2 is PLC control method A62, between the number of lighting fixtures LC1 B1, whether motion control is required B2, whether illuminance control is required B3, and whether scheduling control is required B4, and the cost B7 of the control device LC2 that controls the lighting fixtures LC1, when the control method A6 of lighting fixtures LC1 by control device LC2 is high-function control method A61, between the number of lighting fixtures LC1 B1, whether motion control is required B2, whether illuminance control is required B3, and whether scheduling control is required B4, and the cost B7 of the control device LC2 that controls the lighting fixtures LC1. This includes the relationship with 7, the relationship between the number of lighting fixtures LC1 B1, the necessity of motion sensor control B2, the necessity of illuminance control B3, and the necessity of schedule control B4 when the control method A6 of lighting fixtures LC1 by control device LC2 is wireless control method A63, and the relationship between the number of lighting fixtures LC1 B1, the necessity of motion sensor control B2, the necessity of illuminance control B3, and the necessity of schedule control B4 when the control method A6 of lighting fixtures LC1 by control device LC2 is two-wire control method A64, and the relationship between the cost of control device LC2 that controls lighting fixtures LC1 B7.

[0033] Furthermore, equation B5 contains the same relationship as the relationship between the number of lighting fixtures LC1 B1, the necessity of motion control B2, the necessity of illuminance control B3, and the necessity of schedule control B4 when the control method A6 of lighting fixtures LC1 by the control device LC2 is the PLC control method A62, and the number of sensors LC3 used to control lighting fixtures LC1 B8 when the control method A6 of lighting fixtures LC1 by the control device LC2 is the high-function control method A61, and the number of sensors LC3 used to control lighting fixtures LC1 B This includes the relationship with 8, the relationship between the number of lighting fixtures LC1 B1, whether motion control is required B2, whether illuminance control is required B3, and whether schedule control is required B4 when the control method A6 of lighting fixture LC1 by control device LC2 is wireless control method A63, and the relationship between the number of lighting fixtures LC1 B1, whether motion control is required B2, whether illuminance control is required B3, and whether schedule control is required B4 when the control method A6 of lighting fixture LC1 by control device LC2 is two-wire control method A64, and the relationship between the number of lighting fixtures LC1 B1, whether motion control is required B2, whether illuminance control is required B3, and whether schedule control is required B4, and the number of sensors LC3 used to control lighting fixture LC1.

[0034] Furthermore, equation B5 contains the same relationship as above when the control method A6 of lighting fixtures LC1 by the control device LC2 is the PLC control method A62, between the number of lighting fixtures LC1 B1, whether motion control is required B2, whether illuminance control is required B3, and whether schedule control is required B4, and the cost B9 of the sensor LC3 used to control lighting fixtures LC1, when the control method A6 of lighting fixtures LC1 by the control device LC2 is the high-function control method A61, between the number of lighting fixtures LC1 B1, whether motion control is required B2, whether illuminance control is required B3, and whether schedule control is required B4, and the cost B9 of the sensor LC3 used to control lighting fixtures LC1. This includes the relationship with 9, the relationship between the number of lighting fixtures LC1 B1, the necessity of motion control B2, the necessity of illuminance control B3, and the necessity of schedule control B4 when the control method A6 of lighting fixtures LC1 by control device LC2 is wireless control method A63, and the relationship between the number of lighting fixtures LC1 B1, the necessity of motion control B2, the necessity of illuminance control B3, and the necessity of schedule control B4 when the control method A6 of lighting fixtures LC1 by control device LC2 is two-wire control method A64, and the relationship between the cost of sensors LC3 used to control lighting fixtures LC1 B9.

[0035] In the example shown in Figure 1, the system engineer cost calculation unit 12C calculates the system engineer cost C3 (calculation item) based on the number of lighting fixtures LC1 B1, the control method A6 of the control device LC2 that controls the lighting fixtures LC1, and a predetermined relational expression C0. The lighting control design support system 1 accepts input of the number of lighting fixtures LC1 B1 from the designer of the lighting control system LC. In other words, the number of lighting fixtures LC1 B1 is an input item and is acquired by the acquisition unit 11. The relational expression C0 is stored as a memory item either internally or externally within the lighting control design support system 1 and is acquired by the acquisition unit 11. The relation C0 can be expressed, for example, by equation (1) below. In equation (1) below, C1 is the fixed cost per property, and C2 is the cost per lighting fixture LC1. C3 = C1 + C2 × B1 (1)

[0036] In one example of relational equation C0, when the control method A6 of lighting fixture LC1 by control device LC2 is PLC control method A62, the fixed cost C1 per property (per building in which the lighting control system LC is installed) is, for example, 50,000 yen, and the cost C2 per lighting fixture LC1 is, for example, 200 yen. The relation C0 includes the same relationship between the number of lighting fixtures B1 and the system engineer costs C3 when the control method A6 of lighting fixtures LC1 by the control device LC2 is the PLC control method A62, as described above, as well as the relationship between the number of lighting fixtures B1 and the system engineer costs C3 when the control method A6 of lighting fixtures LC1 by the control device LC2 is the high-function control method A61, the relationship between the number of lighting fixtures B1 and the system engineer costs C3 when the control method A6 of lighting fixtures LC1 by the control device LC2 is the wireless control method A63, and the relationship between the number of lighting fixtures B1 and the system engineer costs C3 when the control method A6 of lighting fixtures LC1 by the control device LC2 is the two-wire control method A64.

[0037] In the example shown in Figure 1, the distribution board design equipment cost calculation unit 12D creates a design drawing D2 for the distribution board LC4 (with the necessary equipment added to the design drawing template D1 for the distribution board LC4) based on the control method A6 for the lighting fixture LC1 by the control equipment LC2, the pre-created design drawing template D1 for the distribution board LC4, and a predetermined relational expression D0. Furthermore, the distribution board design equipment cost calculation unit 12D calculates additional equipment costs D3 (calculation items), which are the costs of equipment added to the distribution board LC4 design drawing template D1 when creating the design drawing D2 of the distribution board LC4, based on the control method A6 of the lighting fixture LC1 by the control equipment LC2 and the relational expression D0.

[0038] Figure 3 is a diagram illustrating an example of relational expression D0, which shows the relationship between the control method A6 for lighting fixture LC1 by control device LC2 and the equipment added to the design drawing template D1 for distribution board LC4 when creating the design drawing D2 for distribution board LC4. In the example shown in Figure 3, if the control method A6 for the lighting fixture LC1 by the control device LC2 is the high-function control method A61, the distribution board design equipment cost calculation unit 12D adds a "master unit" to the distribution board LC4 design drawing template D1 when creating the design drawing D2 for the distribution board LC4. Furthermore, when creating the design drawing D2 for the distribution board LC4, the distribution board design equipment cost calculation unit 12D increases the "cabinet vertical dimension" of the distribution board LC4 design drawing template D1 by "200 mm". In addition, when creating the design drawing D2 for the distribution board LC4, the distribution board design equipment cost calculation unit 12D calculates "5000 yen" as the additional equipment cost D3 (cost of "master unit", etc.), which is the cost of the equipment added to the distribution board LC4 design drawing template D1. Furthermore, if the control method A6 for the lighting fixture LC1 by the control device LC2 is the PLC control method A62, the distribution board design equipment cost calculation unit 12D adds a "master unit" to the distribution board LC4 design drawing template D1 when creating the design drawing D2 for the distribution board LC4. Also, when creating the design drawing D2 for the distribution board LC4, the distribution board design equipment cost calculation unit 12D increases the "cabinet vertical dimension" of the distribution board LC4 design drawing template D1 by "200 mm". In addition, when creating the design drawing D2 for the distribution board LC4, the distribution board design equipment cost calculation unit 12D calculates "5000 yen" as the additional equipment cost D3 (cost of "master unit", etc.) which is the cost of the equipment added to the distribution board LC4 design drawing template D1.

[0039] If the control method A6 for lighting fixture LC1 by control device LC2 is wireless control method A63, the distribution board design equipment cost calculation unit 12D adds a "remote control relay" to the distribution board LC4 design drawing template D1 when creating the design drawing D2 of the distribution board LC4. In addition, when creating the design drawing D2 of the distribution board LC4, the distribution board design equipment cost calculation unit 12D increases the "cabinet vertical dimension" of the distribution board LC4 design drawing template D1 by "100 mm for every 6 additional remote control relays". Furthermore, when creating the design drawing D2 of the distribution board LC4, the distribution board design equipment cost calculation unit 12D calculates an additional equipment cost D3 (cost of "remote control relays," etc.) which is the cost of the equipment added to the distribution board LC4 design drawing template D1, at "2,500 yen for every 6 additional remote control relays (for every 100 mm increase in cabinet vertical dimension)". If the control method A6 for lighting fixture LC1 by control device LC2 is a two-wire control method A64, the distribution board design equipment cost calculation unit 12D adds a "remote control relay" to the distribution board LC4 design drawing template D1 when creating the design drawing D2 for distribution board LC4. In addition, when creating the design drawing D2 for distribution board LC4, the distribution board design equipment cost calculation unit 12D increases the "cabinet vertical dimension" of the distribution board LC4 design drawing template D1 by "100 mm for every 6 additional remote control relays". Furthermore, when creating the design drawing D2 for distribution board LC4, the distribution board design equipment cost calculation unit 12D calculates an additional equipment cost D3 (cost of "remote control relays," etc.) which is the cost of the equipment added to the distribution board LC4 design drawing template D1, at "2,500 yen for every 6 additional remote control relays (for every 100 mm increase in cabinet vertical dimension)". As shown in Figure 6, the additional equipment cost D3 calculated by the distribution board design equipment cost calculation unit 12D is set to different values ​​depending on the control method A6 (high-function control method A61, PLC control method A62, wireless control method A63, and two-wire control method A64) of the lighting fixture LC1 by the control equipment LC2.

[0040] Figure 4 shows an example of a design template D1 for a distribution board LC4 used when creating the design drawing D2 for the distribution board LC4. Specifically, Figure 4(A) shows an example of a design template D1 for a distribution board LC4 used when creating the design drawing D2 for the distribution board LC4, Figure 4(B) shows the design drawing D2 for a distribution board LC4 created by the distribution board design equipment cost calculation unit 12D when the control method A6 for lighting fixture LC1 by the control equipment LC2 is a high-function control method A61 or when the control method A6 for lighting fixture LC1 by the control equipment LC2 is a PLC control method A62, and Figure 4(C) shows the design drawing D2 for a distribution board LC4 created by the distribution board design equipment cost calculation unit 12D when the control method A6 for lighting fixture LC1 by the control equipment LC2 is a wireless control method A63 and there are 20 remote control relays or when the control method A6 for lighting fixture LC1 by the control equipment LC2 is a two-wire control method A64 and there are 20 remote control relays. In the examples shown in Figures 4(A) and 4(B), the distribution board design equipment cost calculation unit 12D creates the distribution board LC4 design drawing D2 by adding a "master unit" as a required piece of equipment to the distribution board LC4 design drawing template D1. The distribution board design equipment cost calculation unit 12D also calculates 5,000 yen as the additional equipment cost D3, which is the cost of the equipment added to the distribution board LC4 design drawing template D1 when creating the distribution board LC4 design drawing D2. In the examples shown in Figures 4(A) and 4(C), the distribution board design equipment cost calculation unit 12D creates the design drawing D2 for the LC4 distribution board by adding "20 remote control relays" as necessary equipment to the design drawing template D1 for the LC4 distribution board. The distribution board design equipment cost calculation unit 12D also calculates an additional equipment cost D3 of approximately 8,000 yen (= 20 units × 2,500 yen / 6 units) as the cost of the equipment added to the design drawing template D1 for the LC4 distribution board when creating the design drawing D2 for the LC4 distribution board.

[0041] In the example shown in Figure 1, the control system cost calculation unit 12E calculates the control system cost E1 (= additional equipment cost D3 + cost of control equipment LC2 for controlling lighting fixture LC1 B7 + cost of sensor LC3 for controlling lighting fixture LC1 B9 + system engineer cost C3) (calculation items) by adding the additional equipment cost D3 calculated by the distribution board design equipment cost calculation unit 12D, the cost of control equipment LC2 for controlling lighting fixture LC1 B7 calculated by the equipment unit cost calculation unit 12B, the cost of sensor LC3 for controlling lighting fixture LC1 B9 + system engineer cost C3 calculated by the system engineer cost calculation unit 12C. In detail, the control system cost calculation unit 12E calculates the control system cost E1 for each control method that is the target of the simulation, such as the initial cost H1 of the lighting control system LC and the annual electricity usage fee J6, among the control methods A6 (high-function control method A61, PLC control method A62, wireless control method A63, and two-wire control method A64) of the lighting fixture LC1.

[0042] In the example shown in Figure 1, the lighting fixture cost difference calculation unit 12F calculates the lighting fixture cost difference F3 (additional cost of lighting fixtures due to the introduction of the lighting control system LC) (calculation item) based on the number of lighting fixtures LC1 B1, the cost of one uncontrolled lighting fixture LE F1, the cost of one lighting fixture LC1 F2, and the following equation (2). F3 = B1 × (F2 - F1) (2)

[0043] The cost F1 of one uncontrolled lighting fixture LE, the cost F2 of one lighting fixture LC1, and the relationship shown in equation (2) above are stored as memory items inside or outside the lighting control design support system 1 and are acquired by the acquisition unit 11.

[0044] In detail, the lighting fixture cost difference calculation unit 12F calculates the lighting fixture cost difference F3 for each control method among the control methods A6 (high-function control method A61, PLC control method A62, wireless control method A63, and 2-wire control method A64) of the lighting control system LC that is the subject of the simulation, such as the initial cost H1 of the lighting control system LC and the annual electricity usage fee J6. For example, the cost F1 of one uncontrolled lighting fixture LE is 10,000 yen, the cost F2 of one lighting fixture LC1 when the control method A6 of lighting fixture LC1 is the high-function control method A61 is 15,000 yen, the cost F2 of one lighting fixture LC1 when the control method A6 of lighting fixture LC1 is the PLC control method A62 is 13,000 yen, the cost F2 of one lighting fixture LC1 when the control method A6 of lighting fixture LC1 is the PLC wireless control method A63 is 16,000 yen, and the cost F2 of one lighting fixture LC1 when the control method A6 of lighting fixture LC1 is the 2-wire control method A64 is 13,000 yen. In other words, the cost F2 per lighting fixture LC1 is set to different values ​​depending on the control method A6 (high-function control method A61, PLC control method A62, wireless control method A63, and 2-wire control method A64) used by the control device LC2 for controlling the lighting fixture LC1.

[0045] In the example shown in Figure 1, the construction cost calculation unit 12G calculates the construction cost G4 (calculation item) based on the labor cost G1 corresponding to the control method A6 of the lighting fixture LC1, the building structure coefficient G2 which is a coefficient corresponding to the building structure (building structure in which the lighting control system LC is introduced) including the lighting fixture LC1 and the distribution board LC4, the construction material cost G3 corresponding to the control method A6 of the lighting fixture LC1, the number of lighting fixtures LC1 B1, and the following equation (3). G4 = (G1 × G2 + G3) × B1 (3)

[0046] Figure 5 shows an example of the relationship between the control method A6 (high-function control method A61, PLC control method A62, wireless control method A63, and 2-wire control method A64) of the lighting fixture LC1 used in calculating the construction cost G4 by the construction cost calculation unit 12G, labor costs G1, and construction material costs G3. In the example shown in Figure 5, when the control method A6 of the lighting fixture LC1 is the high-function control method A61, the labor cost G1 is set to 2,500 yen and the construction material cost G3 is set to 750 yen. When the control method A6 of the lighting fixture LC1 is the PLC control method A62, the labor cost G1 is set to 500 yen and the construction material cost G3 is set to 0 yen. When the control method A6 of the lighting fixture LC1 is the wireless control method A63, the labor cost G1 is set to 500 yen and the construction material cost G3 is set to 0 yen. When the control method A6 of the lighting fixture LC1 is the 2-wire control method A64, the labor cost G1 is set to 2,500 yen and the construction material cost G3 is set to 750 yen. The relationship between the control method A6 of the lighting fixture LC1, labor costs G1, and construction material costs G3, as shown in Figure 5, is stored as a memory item either internally or externally within the lighting control design support system 1 and is acquired by the acquisition unit 11.

[0047] Figure 6 shows an example of a relationship used to obtain the added value to the standard value "1.0" of the building structure coefficient G2, which is used in the calculation of construction cost G4 by the construction cost calculation unit 12G. In the example shown in Figure 6, when the control method A6 for lighting fixture LC1 is the high-function control method A61, and the building structure including lighting fixture LC1 and distribution board LC4 (the building structure in which the lighting control system LC is introduced) is a single-story building, no addition is made to the standard value of the building structure coefficient G2, which is "1.0" (i.e., a value of zero is added). When the control method A6 for lighting fixture LC1 is the high-function control method A61, a value of "0.2" is added to the standard value of the building structure coefficient G2, which is "1.0", for each additional floor in the building structure including lighting fixture LC1 and distribution board LC4. That is, for example, when the control method A6 for lighting fixture LC1 is the high-function control method A61, and the building structure including lighting fixture LC1 and distribution board LC4 is a two-story building, a value of "0.2" is added to the standard value of the building structure coefficient G2, which is "1.0". When the control method A6 for lighting fixture LC1 is the high-function control method A61, and the building structure including lighting fixture LC1 and distribution board LC4 is three stories high, a value of "0.4" is added to the standard value of "1.0" for the building structure coefficient G2. If the control method A6 for lighting fixture LC1 is the high-function control method A61, and the distance from the distribution board LC4 to lighting fixture LC1 is 1m or less, no addition is made to the standard value of the building structure coefficient G2, which is "1.0" (i.e., a value of zero is added). If the control method A6 for lighting fixture LC1 is the high-function control method A61, for every 3m increase in the distance from the distribution board LC4 to lighting fixture LC1 between 1m and LC1, a value of "0.1" is added to the standard value of the building structure coefficient G2, which is "1.0". That is, for example, if the control method A6 for lighting fixture LC1 is the high-function control method A61, and the distance from the distribution board LC4 to lighting fixture LC1 is greater than 1m but 4m or less, a value of "0.1" is added to the standard value of the building structure coefficient G2, which is "1.0". If the control method A6 for lighting fixture LC1 is the high-function control method A61, and the distance from the distribution board LC4 to lighting fixture LC1 is greater than 4m but 7m or less, then an additional value of "0.2" is added to the standard value of "1.0" for the building structural coefficient G2. If the control method A6 of lighting fixture LC1 is the high-function control method A61, and the ceiling height of the building in which the lighting control system LC is installed is 3m or less, then no addition is made to the standard value of the building structural coefficient G2, which is "1.0" (i.e., a value of zero is added). If the control method A6 of lighting fixture LC1 is the high-function control method A61, then for every 1m increase in the ceiling height of the building in which the lighting control system LC is installed from 3m, an additional value of "0.1" is added to the standard value of the building structural coefficient G2, which is "1.0". That is, for example, if the control method A6 of lighting fixture LC1 is the high-function control method A61, and the ceiling height of the building in which the lighting control system LC is installed is greater than 3m but 4m or less, then an additional value of "0.1" is added to the standard value of the building structural coefficient G2, which is "1.0". If the control method A6 for lighting fixture LC1 is the high-performance control method A61, and the ceiling height of the building where the lighting control system LC is installed is greater than 4m but less than or equal to 5m, then an additional value of "0.2" is added to the standard value of "1.0" for the building structural coefficient G2.

[0048] If the control method A6 for lighting fixture LC1 is the PLC control method A62, then no addition is made to the standard value "1.0" of the building structure coefficient G2, which corresponds to the building structure including lighting fixture LC1 and distribution board LC4 (the building structure in which the lighting control system LC is installed) (i.e., a value of zero is added). Furthermore, if the control method A6 for lighting fixture LC1 is PLC control method A62, the standard value "1.0" for the building structure coefficient G2, which corresponds to the distance from the distribution board LC4 to the lighting fixture LC1, is not added (i.e., a value of zero is added). When the control method A6 of lighting fixture LC1 is the PLC control method A62, and the ceiling height of the building in which the lighting control system LC is installed is 3m or less, no addition is made to the standard value of the building structure coefficient G2, which is "1.0" (i.e., a value of zero is added). When the control method A6 of lighting fixture LC1 is the PLC control method A62, for every 1m increase in the ceiling height of the building in which the lighting control system LC is installed from 3m, a value of "0.1" is added to the standard value of the building structure coefficient G2, which is "1.0". That is, for example, when the control method A6 of lighting fixture LC1 is the PLC control method A62, and the ceiling height of the building in which the lighting control system LC is installed is greater than 3m but 4m or less, a value of "0.1" is added to the standard value of the building structure coefficient G2, which is "1.0". If the control method A6 for lighting fixture LC1 is the PLC control method A62, and the ceiling height of the building where the lighting control system LC is installed is greater than 4m but less than or equal to 5m, then a value of "0.2" is added to the standard value of "1.0" for the building structural coefficient G2.

[0049] When the control method A6 for lighting fixture LC1 is either wireless control method A63 or two-wire control method A64, and the building structure including lighting fixture LC1 and distribution board LC4 (the building structure in which the lighting control system LC is installed) is a single-story building, no addition is made to the standard value of the building structure coefficient G2, which is "1.0" (i.e., a value of zero is added). When the control method A6 for lighting fixture LC1 is either wireless control method A63 or two-wire control method A64, a value of "0.2" is added to the standard value of the building structure coefficient G2, which is "1.0", for each additional floor in the building structure including lighting fixture LC1 and distribution board LC4. If the control method A6 for lighting fixture LC1 is wireless control method A63 or two-wire control method A64, and the distance from distribution board LC4 to lighting fixture LC1 is 1m or less, no addition is made to the standard value "1.0" of the building structure coefficient G2 (i.e., a value of zero is added). If the control method A6 for lighting fixture LC1 is wireless control method A63 or two-wire control method A64, an additional value of "0.1" is added to the standard value "1.0" of the building structure coefficient G2 for every 3m increase in distance from distribution board LC4 to lighting fixture LC1. If the control method A6 of lighting fixture LC1 is wireless control method A63 or two-wire control method A64, and the ceiling height of the building in which the lighting control system LC is installed is 3m or less, then no addition is made to the standard value of the building structural coefficient G2 of "1.0" (i.e., a value of zero is added). If the control method A6 of lighting fixture LC1 is wireless control method A63 or two-wire control method A64, then for every 1m increase in the ceiling height of the building in which the lighting control system LC is installed from 3m, an additional value of "0.1" is added to the standard value of the building structural coefficient G2 of "1.0".

[0050] For example, if the control method A6 for lighting fixture LC1 is PLC control method A62, the building structure including lighting fixture LC1 and distribution board LC4 is two stories high (i.e., no addition to the standard value "1.0" for the building structure coefficient G2), the distance from distribution board LC4 to lighting fixture LC1 is 3m (i.e., no addition to the standard value "1.0" for the building structure coefficient G2), and the ceiling height of the building where the lighting control system LC is installed is 5m (i.e., higher than 4m and 5m or less), then the construction cost calculation unit 12G calculates a value of "1.2 (= standard value "1.0" + added value "0.2")" as the building structure coefficient G2 (calculation item). Furthermore, the construction cost calculation unit 12G calculates "120,000 yen (= (500 yen × 1.2 + 0 yen) × 200 units)" as the construction cost G4 when the number of lighting fixtures LC1 B1 is 200 units. As shown in Figure 6, the value of the building structural coefficient G2 differs depending on the control method A6 of the lighting fixture LC1 by the control device LC2 (high-function control method A61, PLC control method A62, wireless control method A63, and two-wire control method A64). Therefore, it can be said that the construction cost G4 of the lighting control system LC is set to different values ​​depending on the control method A6 of the lighting fixture LC1 by the control device LC2. Furthermore, as shown in Figure 6, the value of the building structure coefficient G2 varies depending on the structure of the building in which the lighting control system LC is installed (number of floors, distance from the distribution board LC4 to the lighting fixture LC1, and ceiling height of the building). Therefore, it can be said that the construction cost G4 of the lighting control system LC is set to a different value depending on the structure of the building in which the lighting control system LC is installed.

[0051] In the example shown in Figure 1, the initial cost calculation unit 12H calculates the initial cost H1 when the lighting control system LC is introduced, based on at least the number of lighting fixtures LC1 B6, the cost per lighting fixture LC1 F2, the cost of control equipment LC2 B7, the cost related to the distribution board LC4, and the installation cost G4 of the lighting control system LC. The cost related to the distribution board LC4 includes, for example, the cost of additional equipment D3, which is the cost of equipment added to the design drawing template D1 of the distribution board LC4 when creating the design drawing D2 of the distribution board LC4. In detail, in the example shown in Figure 1, the initial cost calculation unit 12H calculates the control system cost E1 calculated by the control system cost calculation unit 12E (= additional equipment cost D3, which is the cost of equipment added to the design drawing template D1 of the distribution board LC4 when creating the design drawing D2 of the distribution board LC4 + cost B7 of the control equipment LC2 that controls the lighting fixture LC1 + cost B9 of the sensor LC3 used to control the lighting fixture LC1 + system engineer cost C3) and the lighting fixture cost difference F3 calculated by the lighting fixture cost difference calculation unit 12F ( The initial cost H1 (= control system cost E1 + lighting fixture cost difference F3 + construction cost G4) (calculated items) when the lighting control system LC is introduced is calculated by adding the number of lighting fixtures LC1 B1 × (cost per lighting fixture LC1 F2 - cost per uncontrolled lighting fixture LE F1)) and the construction cost G4 calculated by the construction cost calculation unit 12G (= (labor cost G1 according to the control method A6 of lighting fixture LC1 × building structure coefficient G2 + construction material cost G3) × number of lighting fixtures LC1 B1). In other words, the initial cost H1 when the lighting control system LC is introduced includes the difference in lighting fixture costs F3, which is the product of the difference between the cost F2 per lighting fixture LC1 and the cost F1 per uncontrolled lighting fixture LE (=F2-F1) and the number of lighting fixtures LC1 (B6) (=(F2-F1)×B6). In addition, the initial cost H1 when the lighting control system LC is introduced includes the installation cost G4 of the lighting control system LC. In detail, the initial cost calculation unit 12H calculates the initial cost H1 for each control method among the control methods A6 (high-function control method A61, PLC control method A62, wireless control method A63, and 2-wire control method A64) of the lighting fixture LC1 that is the subject of the simulation of the initial cost H1 of the lighting control system LC. In the example shown in Figure 1, the building structure coefficient G2 (information indicating the structure of the building in which the lighting control system LC is installed) is used to calculate the initial cost H1 when the lighting control system LC is installed. However, in other examples, the building structure coefficient G2 (information indicating the structure of the building in which the lighting control system LC is installed) may not be used to calculate the initial cost H1 when the lighting control system LC is installed. In the example shown in Figure 1, the lighting fixture cost difference F3 (= number of lighting fixtures LC1 B1 × (cost per lighting fixture LC1 F2 - cost per uncontrolled lighting fixture LE F1)) calculated by the lighting fixture cost difference calculation unit 12F is used to calculate the initial cost H1 when the lighting control system LC is introduced. However, in other examples, the lighting fixture cost difference F3 may not be used to calculate the initial cost H1 when the lighting control system LC is introduced.

[0052] In the example shown in Figure 1, the first power usage charge calculation unit 12I calculates the daily power usage charge I4 (calculation item) for uncontrolled lighting fixtures LE based on the power consumption I1 (input item) per uncontrolled lighting fixture LE, the number of uncontrolled lighting fixtures LE, the electricity usage time (usage time of uncontrolled lighting fixtures LE) I2 (input item), the power usage charge unit price I3 (storage item), and the following formula (4) (storage item). Specifically, the first power usage charge calculation unit 12I uses the number of lighting fixtures LC1 B1 as the number of uncontrolled lighting fixtures LE. Furthermore, the first power usage charge calculation unit 12I uses the electricity usage time (usage time of lighting fixture LC1) J2, which will be described later, as the electricity usage time (usage time of uncontrolled lighting fixtures LE) I2. In addition, the first power usage charge calculation unit 12I uses the power usage charge unit price J3, which will be described later, as the power usage charge unit price I3. I4 = I1 × B1 × I2 × I3 (4)

[0053] Furthermore, the first power usage charge calculation unit 12I calculates the annual power usage charge I5 (calculation item) for the uncontrolled lighting fixture LE based on the daily power usage charge I4 for the uncontrolled lighting fixture LE and the following formula (5) (storage item). The annual power usage charge I5 for the uncontrolled lighting fixture LE corresponds to the "annual power usage charge when the lighting control system LC is not installed". I5 = I4 × 365 (5)

[0054] In the example shown in Figure 1, the second electricity usage charge calculation unit 12J calculates the daily electricity usage charge J5 (calculation item) for lighting fixtures LC1 based on the power consumption J1 (input item) of each lighting fixture LC1 (i.e., lighting fixture LC1 on which lighting control method A6 is performed), the number of lighting fixtures LC1 B1, the electricity usage time (usage time of lighting fixture LC1) J2 (input item), the electricity usage charge unit price J3 (storage item), the reduced rate J4 (input item) which shows the ratio of electricity usage when control method A6 is applied to electricity usage when control method A6 is not applied, and the following equation (6) (storage item). Specifically, as the reduced rate J4 which shows the ratio of electricity usage when control method A6 is applied to electricity usage when control method A6 is not applied, a value greater than zero and less than 1 is input to the lighting control design support system 1 by the designer of the lighting control system LC. In other words, in the lighting control design support system 1 of the first embodiment, since control method A6 is applied to lighting fixture LC1, the power consumption when control method A6 is applied (power consumption by lighting fixture LC1) is assumed to be less than the power consumption when control method A6 is not applied (power consumption by uncontrolled lighting fixture LE). J5 = J1 × B1 × J2 × J3 × J4 (6)

[0055] Furthermore, the second power usage charge calculation unit 12J calculates the annual power usage charge J6 (calculation item) for lighting fixture LC1 based on the daily power usage charge J5 for lighting fixture LC1 and the following formula (7) (storage item). The annual power usage charge J6 for lighting fixture LC1 corresponds to the "annual power usage charge when the lighting control system LC is installed". J6 = J5 × 365 (7)

[0056] In the example shown in Figure 1, the first initial cost recovery period calculation unit 12K calculates the first initial cost recovery period K1 (calculation item), which is the number of years required to recover the initial cost H1, based on the initial cost calculation unit 12H's calculation of the initial cost H1 when the lighting control system LC is introduced (specifically, when the lighting control system LC is not linked with the air conditioning demand control system), the first electricity usage charge calculation unit 12I's calculation of the annual electricity usage charge for uncontrolled lighting fixtures LE (annual electricity usage charge when the lighting control system LC is not introduced), the second electricity usage charge calculation unit 12J's calculation of the annual electricity usage charge for lighting fixtures LC1 (annual electricity usage charge when the lighting control system LC is introduced), and the following equation (8) (storage item). K1 = H1 / (I5 - J6) (8)

[0057] In the example shown in Figure 1, the energy saving amount calculation unit 12L calculates the energy saving amount L2 (calculated item) at the point when the number of years L1 has elapsed since the introduction of the lighting control system LC, based on the initial cost calculation unit 12H's initial cost H1, the annual electricity usage charge for uncontrolled lighting fixtures LE (annual electricity usage charge when the lighting control system LC is not introduced) I5 calculated by the first electricity usage charge calculation unit 12I, the annual electricity usage charge for lighting fixture LC1 (annual electricity usage charge when the lighting control system LC is introduced) J6 calculated by the second electricity usage charge calculation unit 12J, the number of years elapsed since the introduction of the lighting control system LC L1, and the following equation (9) (storage item). Specifically, the energy saving amount L2 will be a negative value in years before the initial cost H1 is recovered, and a positive value in years after the initial cost H1 is recovered. L2 = I5 × L1 - (H1 + J6 × L1) (9)

[0058] In other words, the energy saving amount calculation unit 12L calculates the energy saving amount L2 at the point when L1 years have elapsed since the introduction of the lighting control system LC by adding the product of the annual electricity usage fee J6 when the lighting control system LC is introduced and the number of years elapsed since the introduction of the lighting control system LC (=J6×L1) (=H1+J6×L1) to the initial cost H1 when the lighting control system LC is introduced (=H1+J6×L1), and then subtracting this from the product of the annual electricity usage fee I5 when the lighting control system LC is not introduced and the number of years elapsed since the introduction of the lighting control system LC (=I5×L1) (=I5×L1-(H1+J6×L1)). In detail, the energy saving amount calculation unit 12L calculates the energy saving amount L2 for each control method of the lighting fixture LC1 by the control device LC2 (i.e., for each control method among the high-function control method A61, PLC control method A62, wireless control method A63, and two-wire control method A64 that is the subject of the energy saving amount L2 simulation) at the time when a number of years L1 has elapsed since the lighting control system LC was introduced.

[0059] Figure 7 shows an example of the relationship between the initial cost H1 when the control method for lighting fixture LC1 by control device LC2 is PLC control method A62, the product of the annual electricity usage fee J6 when PLC control method A62 is introduced and the number of years elapsed since PLC control method A62 was introduced (=J6×L1) (=H1+J6×L1), the product of the annual electricity usage fee I5 when the lighting control system LC is not introduced and the number of years elapsed since PLC control system LC was introduced (=I5×L1) (=I5×L1), and the amount of energy saved L2 (=I5×L1-(H1+J6×L1)). In the example shown in Figure 7, the control method for lighting fixture LC1 by control device LC2 is PLC control method A62, the initial cost H1 is 2,815,000 yen, the annual electricity usage fee I5 for lighting fixture LE without control (annual electricity usage fee when the lighting control system LC is not installed) is 481,800 yen, and the annual electricity usage fee J6 for lighting fixture LC1 (annual electricity usage fee when the lighting control system LC is installed) is 289,080 yen. As shown in Figure 7, the energy saving amount L2 is negative in the years before the initial cost H1 is recovered (i.e., when the number of years L1 elapsed since the introduction of the PLC control system A62 is 14 or less), and positive in the years after the initial cost H1 has been recovered (i.e., when the number of years L1 elapsed since the introduction of the PLC control system A62 is 15 or more). In detail, in the example shown in Figure 7, the first initial cost recovery period K1 is approximately 14.6 years (= 2,815,000 / (4,818,000 - 2,890,080)).

[0060] In the example shown in Figure 1, the greenhouse gas reduction calculation unit 12M calculates the daily greenhouse gas reduction amount M2 (calculation item) based on the power consumption J1 of each lighting fixture LC1, the value obtained by subtracting the reduction rate J4 from 1 (=1-J4), the number of lighting fixtures LC1 B1, the electricity usage time (usage time of lighting fixtures LC1) J2, the greenhouse gas emission coefficient M1 (input item or stored item) obtained from a website such as the one shown at the URL below, and the following equation (10) (stored item). M2=J1×(1-J4)×B1×J2×M1 (10) https: / / www.env.go.jp / press / files / jp / 115373.pdf https: / / ghg-santeikohyo.env.go.jp / files / calc / itiran_2020_rev.pdf https: / / ghg-santeikohyo.env.go.jp / files / calc / r04_coefficient_rev.pdf https: / / www.tepco.co.jp / ep / notice / news / 2021 / 1628675_8909.html https: / / www.enecho.meti.go.jp / about / whitepaper / 2016html / 1-3-3.html

[0061] Furthermore, the greenhouse gas reduction calculation unit 12M calculates the annual greenhouse gas reduction amount M3 based on the daily greenhouse gas reduction amount M2 and the following equation (11) (memory item). M3 = M2 × 365 (11)

[0062] In the example shown in Figure 1, the second initial cost recovery period calculation unit 12N calculates the initial cost H1 (specifically, the initial cost associated only with the introduction of the lighting control system LC) calculated by the initial cost calculation unit 12H when the lighting control system LC is introduced, the initial cost N1 (input item) for the air conditioning demand control system which is the initial cost when an air conditioning demand control system that works in conjunction with the lighting control system LC is introduced, and the annual electricity usage charge for uncontrolled lighting fixtures LE (when the lighting control system LC is introduced) calculated by the first electricity usage charge calculation unit 12I. Based on the annual electricity usage charge (if not installed) I5, the annual electricity usage charge for lighting fixtures LC1 calculated by the second electricity usage charge calculation unit 12J (annual electricity usage charge when the lighting control system LC is installed) J6, the amount of reduction in annual electricity usage charges due to the installation of the air conditioning demand control system N2, and the following formula (12) (memory item), the second initial cost recovery period N3 (calculation item), which is the number of years required to recover the initial cost H1 and the initial cost N1 of the air conditioning demand control system, is calculated. N3 = (H1 + N1) / (I5 - J6 + N2) (12)

[0063] Figure 8 shows an example of the simulation results obtained by the lighting control design support system 1 of the first embodiment. In the example shown in Figure 8(A), the lighting control design support system 1 calculates "0 yen" as the control system cost E1 in the case where the lighting control system LC is not introduced (i.e., uncontrolled lighting fixtures LE are used and lighting control is not performed using control method A6), calculates "0 yen" as the difference in lighting fixture costs F3, calculates "0 yen" as the construction cost G4, calculates "0 yen" as the initial cost H1, and calculates "481,800 yen" as the annual electricity usage charge I5 for uncontrolled lighting fixtures LE. Furthermore, in the case where the lighting control design support system 1 introduces the lighting control system LC and the high-performance control method A61 is selected as the control method A6 for lighting fixture LC1, the control system cost E1 is calculated as "2,500,000 yen", the difference in lighting fixture cost F3 is calculated as "1,000,000 yen", the construction cost G4 is calculated as "900,000 yen", the initial cost H1 is calculated as "4,400,000 yen", and the annual power usage of lighting fixture LC1 is calculated. We calculate the charge J6 as "289,080 yen", the first initial cost recovery period K1 as "22.8 years", the annual greenhouse gas reduction M3 as "3.85 tons", the initial cost N1 of the air conditioning demand control system as "1,000,000 yen", the annual reduction in electricity usage charges N2 due to the introduction of the air conditioning demand control system as "300,000 yen", and the second initial cost recovery period N3 as "11.0 years".

[0064] When the lighting control design support system 1 introduces the lighting control system LC and the PLC control method A62 is selected as the control method A6 for lighting fixture LC1, the control system cost E1 is calculated as "2,095,000 yen", the difference in lighting fixture cost F3 is calculated as "600,000 yen", the construction cost G4 is calculated as "120,000 yen", the initial cost H1 is calculated as "2,815,000 yen", and the annual power usage fee for lighting fixture LC1 is calculated. We calculate "289,080 yen" as the cost J6, calculate "14.6 years" as the first initial cost recovery period K1, calculate "3.85 tons" as the annual greenhouse gas reduction M3, calculate "300,000 yen" as the initial cost N1 of the air conditioning demand control system, calculate "300,000 yen" as the annual reduction in electricity usage charges N2 due to the introduction of the air conditioning demand control system, and calculate "6.3 years" as the second initial cost recovery period N3. Furthermore, the lighting control design support system 1 calculates the control system cost E1 as "1,700,000 yen" when the lighting control system LC is introduced and wireless control method A63 is selected as the control method A6 for lighting fixture LC1, calculates the lighting fixture cost difference F3 as "1,200,000 yen", calculates the construction cost G4 as "150,000 yen", calculates the initial cost H1 as "3,050,000 yen", calculates the annual electricity usage fee J6 for lighting fixture LC1 as "289,080 yen", calculates the first initial cost recovery period K1 as "15.8 years", and calculates the annual greenhouse gas reduction amount M3 as "3.85 t". Furthermore, the lighting control design support system 1 calculates the control system cost E1 as "1,500,000 yen" when the lighting control system LC is introduced and the 2-wire control method A64 is selected as the control method A6 for lighting fixture LC1, calculates the lighting fixture cost difference F3 as "600,000 yen", calculates the construction cost G4 as "900,000 yen", calculates the initial cost H1 as "3,000,000 yen", calculates the annual electricity usage fee J6 for lighting fixture LC1 as "289,080 yen", calculates the first initial cost recovery period K1 as "15.6 years", and calculates the annual greenhouse gas reduction amount M3 as "3.85 tons".

[0065] In the example shown in Figure 8(B), when PLC control method A62 is selected as the control method A6 for lighting fixture LC1, the energy saving amount L2 will be a negative value in the years before the initial cost H1 is recovered (i.e., when the number of years L1 elapsed since the introduction of PLC control method A62 is 14 or less), and a positive value in the years after the initial cost H1 has been recovered (i.e., when the number of years L1 elapsed since the introduction of PLC control method A62 is 15 or more). On the other hand, if the high-performance control method A61 is selected as the control method A6 for the lighting fixture LC1, the energy saving amount L2 will not be a positive value even if the number of years L1 elapsed since the introduction of the high-performance control method A61 reaches 15 years.

[0066] In the example shown in Figure 1, the system configuration diagram creation unit 12P calculates the number of lighting fixtures LC1 per floor P2 (calculated item) based on the number of lighting fixtures LC1 B1, the number of floors in the building where the lighting control system LC is installed P1 (input item), and the following equation (13) (storage item). P2 = B1 / P1 (13)

[0067] Furthermore, the system configuration diagram creation unit 12P calculates the number of control devices LC2 per floor P3 (calculation item) based on the number of control devices LC2 that control the lighting fixtures LC1 B6, the number of floors P1 in the building where the lighting control system LC is installed, and the following equation (14) (memory item). P3 = B6 / P1 (14)

[0068] Furthermore, the system configuration diagram creation unit 12P calculates the number of sensors LC3 per floor P4 (calculation item) based on the number of sensors LC3 used to control the lighting fixture LC1 B8, the number of floors P1 in the building where the lighting control system LC is installed, and the following equation (15) (storage item). P4 = B8 / P1 (15)

[0069] Furthermore, the system configuration diagram creation unit 12P creates a system configuration diagram P7 corresponding to the number of floors P1 of the building in which the lighting control system LC is installed, based on the number of lighting fixtures LC1 per floor P2, the number of control devices LC2 per floor P3, the number of sensors LC3 per floor P4, and the hierarchical unit basic system configuration diagram P5 and distribution board diagram P6 which are stored as memory items inside or outside the lighting control design support system 1.

[0070] Figure 9 shows an example of a hierarchical basic system configuration diagram P5 and a distribution board diagram P6 used by the system configuration diagram creation unit 12P. Figure 10 shows an example of a system configuration diagram P7 corresponding to the floor P1 of a building in which the lighting control system LC is installed, created using the hierarchical basic system configuration diagram P5 and distribution board diagram P6 shown in Figure 9. In the examples shown in Figures 9 and 10, the system configuration diagram creation unit 12P creates a system configuration diagram P7 when the PLC control method A62 is selected as the control method A6 for the lighting fixture LC1. In detail, the system configuration diagram creation unit 12P first stacks the hierarchical unit basic system configuration diagram P5 shown in Figure 9 by the number of floors P1 (in the example shown in Figures 9 and 10, "2") of the building in which the lighting control system LC is installed (that is, it stacks two hierarchical unit basic system configuration diagrams P5). Secondly, the system configuration diagram creation unit 12P changes the number of lighting fixtures LC1 "00" in the hierarchical unit basic system configuration diagram P5 to the number of lighting fixtures LC1 per floor P2 in the system configuration diagram P7, changes the number of control devices LC2 ("slave units") "00" in the hierarchical unit basic system configuration diagram P5 to the number of control devices LC2 per floor P3 in the system configuration diagram P7, and changes the number of sensors LC3 ("motion sensors") "00" in the hierarchical unit basic system configuration diagram P5 to the number of sensors LC3 per floor P4 in the system configuration diagram P7. Thirdly, the system configuration diagram creation unit 12P places the distribution board diagram P6 shown in Figure 9 next to the first floor portion of the system configuration diagram P7 shown in Figure 10. As a result, the system configuration diagram P7 shown in Figure 10 is created by the system configuration diagram creation unit 12P without the need for the designer of the lighting control system LC to create the system configuration diagram P7.

[0071] Figure 11 is a flowchart illustrating an example of the process performed in the lighting control design support system 1 of the first embodiment. In the example shown in Figure 11, in step S1, the lighting control design support system 1 receives input from the designer of the lighting control system LC, including the number of lighting fixtures LC1 B1 and the structure of the building in which the lighting control system LC will be installed. In step S3, the lighting control design support system 1 accepts input from the designer of the lighting control system LC regarding whether or not integration with other systems (security system, disaster prevention system, air conditioning management system, air conditioning demand control system) is necessary. In steps S1 and S3, the information received by the lighting control design support system 1 is acquired by the acquisition unit 11 as information used in the design of the lighting control system LC.

[0072] In step S4, the control method selection unit 12A selects the control method A6 for the lighting fixture LC1 using the control device LC2, and the equipment cost calculation unit 12B calculates the number of control devices B6 for controlling the lighting fixture LC1 and the number of sensors B8 used for controlling the lighting fixture LC1. In step S5, the equipment cost calculation unit 12B calculates the cost B7 of the control equipment LC2 that controls the lighting fixture LC1 and the cost B9 of the sensor LC3 used to control the lighting fixture LC1, and the system engineer cost calculation unit 12C calculates the system engineer cost C3. In step S6, the distribution board design equipment cost calculation unit 12D creates a design drawing D2 of the distribution board LC4 (with the necessary equipment added to the design drawing template D1 of the distribution board LC4), and calculates the additional equipment cost D3, which is the cost of the equipment added to the design drawing template D1 of the distribution board LC4 when creating the design drawing D2 of the distribution board LC4.

[0073] In step S7, the control system cost calculation unit 12E calculates the control system cost E1 (= additional equipment cost D3 + cost of control equipment LC2 that controls lighting fixture LC1 B7 + cost of sensor LC3 used to control lighting fixture LC1 B9 + system engineer cost C3). In step S8, the lighting fixture cost difference calculation unit 12F calculates the lighting fixture cost difference F3 (the additional cost of lighting fixtures due to the introduction of the lighting control system LC). In step S9, the construction cost calculation unit 12G calculates the construction cost G4. In step S10, the initial cost calculation unit 12H calculates the initial cost H1 when the lighting control system LC is introduced.

[0074] In step S11, the first power usage charge calculation unit 12I calculates the annual power usage charge I5 for uncontrolled lighting fixtures LE. In step S12, the second electricity usage charge calculation unit 12J calculates the annual electricity usage charge J6 for the lighting fixture LC1. In step S13, the first initial cost recovery period calculation unit 12K calculates the first initial cost recovery period K1, which is the number of years required to recover the initial cost H1. In step S14, the energy saving amount calculation unit 12L calculates the energy saving amount L2 at the time when L1 has elapsed since the introduction of the lighting control system LC. In step S14, for each control method A6 of the lighting fixture LC1 by the control device LC2, the energy saving amount L2 at the time when L1 has elapsed since the introduction of the lighting control system LC is calculated. In step S15, the greenhouse gas reduction calculation unit 12M calculates the annual greenhouse gas reduction amount M3.

[0075] When the lighting control system LC is linked with the air conditioning demand control system, in step S16, the second initial cost recovery period calculation unit 12N calculates the second initial cost recovery period N3, which is the number of years required to recover the initial cost H1 and the initial cost N1 of the air conditioning demand control system.

[0076] In step S17, the system configuration diagram creation unit 12P creates a system configuration diagram P7 corresponding to the floor P1 of the building where the lighting control system LC is installed.

[0077] According to the lighting control design support system 1 of the first embodiment, it is possible to support the design of the lighting control system LC while allowing the designer of the lighting control system LC to understand the amount of energy saved L2 by introducing the lighting control system LC for each control method A6 of the lighting fixture LC1.
