In addition, when a floor central (FC) type main ventilation fan is adopted, the control unit 11 outputs only "duct type first type ventilation equipment".

[0102] In addition, the control unit 11 selects one of options, such as "input specific power consumption," "do not input specific power consumption (do not evaluate energy saving methods)," or "do not input specific power consumption (adopt energy saving methods)," as the input for the specific power consumption to be output. In addition, if the main ventilation fan received as secondary information is a wall-mounted type, the control unit 11 selects one of options such as "enter specific power consumption" or "do not enter specific power consumption (use default value)" as the evaluation method to be output. Here, when "input specific power consumption" is selected as the input of the specific power consumption, the control unit 11 calculates the specific power consumption. On the other hand, if "Do not input specific power consumption (adopt energy saving method)" is selected as the input for specific power consumption, the control unit 11 selects an energy saving method from among options such as "Use a duct with a large diameter" or "Use a duct with a large diameter and adopt a DC motor".

[0103] Furthermore, the control unit 11 calculates the effective ventilation rate of each ventilator that has been input as secondary information. Then, the control unit 11 selects the lowest value from among the calculated effective ventilation rates as the effective ventilation rate to be output.

[0104] In addition, if the main ventilation fan whose input has been accepted as secondary information is a floor central type, in this generation process, the control unit 11 may refer to a table that lists combination patterns of various performance information, and select a pattern depending on the specific power consumption and the presence or absence of an auxiliary ventilation fan.

[0105] (Output of information on the ventilation performance of buildings) After accepting the input of the primary, secondary, and tertiary information, the control unit 11 executes an output process (step S14). In the information generation process according to the present embodiment, the control unit 11 33When the display indicates that the input of the tertiary information has been completed (all primary, secondary and tertiary information has been properly input), the output process is executed when the output button B on the first input screen S1 is clicked or touched. In this output process, the control unit 11 outputs the performance information generated in the above generation process. Since the performance information is generated based on primary information, secondary information, and tertiary information, this output process outputs the performance information based on the primary information, secondary information, and tertiary information.

[0106] In the output process according to this embodiment, the control unit 11 causes the display unit 13 to display an output screen. The output screen has, for example, a ventilation method display field 1, an evaluation method display field, a power / method display field, a ventilation rate display field, and an effective ventilation rate display field.

[0107] Then, the control unit 11 displays the ventilation facility type selected in the above generation process in the ventilation type display field. Moreover, the control unit 11 causes the input of the specific power consumption selected in the above generation process to be displayed in the evaluation method display field. In addition, if the specific power consumption is calculated in the generation process or an energy-saving method is selected, the control unit 11 displays the specific power consumption calculated in the generation process or the selected energy-saving method in the power / method display field. Furthermore, the control unit 11 causes the ventilation rate display field to display a predetermined ventilation rate per unit time (for example, 0.5 times / hour). Moreover, the control unit 11 causes the effective ventilation rate display field to display the effective ventilation rate selected in the above generation process.

[0108] Various performance information is required to be filled in on application documents for ventilation equipment. This allows the user to complete at least a portion of the application documents simply by copying the output information as is. Furthermore, since the output process according to this embodiment can only be executed once the primary, secondary, and tertiary information has been appropriately input, the output performance information is essentially error-free (no correction is required).

[0109] In the above generation process, the control unit 11 may calculate the ventilation rate per unit time based on the primary, secondary, and tertiary information. In the output process, the control unit 11 may output the ventilation rate calculated in the generation process. By executing the output process described above, the control unit 11 and the display unit 13 according to this embodiment function as an output unit.

[0110] [3. Other] In the output process according to the above embodiment, the control unit 11 is configured to output only performance information in the output process, but if necessary, information regarding heat exchange may be generated in the above generation process and output together with the performance information in the output process. Furthermore, in the above output process, the control unit 11 is configured to simply display the performance information, but it may also be configured to design the ventilation equipment (determine the layout, etc.) based on the performance information. In addition, the information generation program P may be capable of rewriting at least one of the arithmetic formulas and tables used to calculate various numerical values, and the options and thresholds used to select various information, in accordance with changes in laws and regulations.

[0111] [4. Effects] As described above, the information generation device 1 storing the information generation program P of this embodiment executes a first input process S2 that accepts input of primary information, a second input process S4 that accepts input of secondary information, a third input process S6 that accepts input of tertiary information, and an output process S8 that outputs performance information based on the primary information, secondary information, and tertiary information. The performance information output based on the primary information, secondary information, and tertiary information reflects information about the ducts of the ventilation equipment in addition to the primary information and secondary information. Therefore, according to the information generating device 1 of this embodiment, even if the ventilation equipment installed in the building has a duct, information on the ventilation performance of the equipment can be easily output.
