Embodiment 1 FIG.
FIG. 1 is a block diagram showing the configuration of the energy saving activity evaluation apparatus according to the first embodiment. The energy-saving activity evaluation apparatus shown in FIG. 1 includes an energy usage amount acquisition unit 1 that acquires the energy usage amount of each equipment in the facility, and an energy usage amount aggregation unit 2 that totalizes the energy usage amount for each predetermined evaluation group. Energy saving index registration means 3 in which one or more energy saving contribution degree evaluation indices are registered, and energy saving evaluation that quantifies the energy saving contribution for each evaluation group according to one or more indices registered in the energy saving index registration means 3 Means 4, evaluation result display means (evaluation result presentation means) 5 for displaying the evaluation result on the screen, and additional information display means (additional information presentation means) 6 for displaying the additional information of the evaluation result on the screen.

  The energy usage amount acquisition means 1 acquires the data by measuring the energy usage amount of equipment in a facility (for example, a building) that is an object of energy saving activity evaluation using a power meter or the like. Moreover, the energy usage amount totaling means 2 classifies each facility device for each predetermined evaluation group, and totals the energy usage amount of the facility device included in each evaluation group according to a predetermined aggregation condition. Units of evaluation groups include tenants, departments, floors, building east side, and building west side. As a totaling condition, for example, there is a condition that the energy usage amount of the air conditioning equipment acquired for each tenant (evaluation group) is totaled in units of one day and converted into the basic unit of energy. Assume that the unit of the evaluation group and the conditions for aggregation are set in advance for each of the indices described later.

  The energy saving index registration means 3 accepts and registers in advance an energy saving index to be evaluated by the energy saving activity evaluation apparatus through an input device (not shown) or the like. In addition, the energy saving evaluation means 4 converts the energy usage total result into a multi-stage numerical value for the index registered in the energy saving index registration means 3 to obtain an energy saving evaluation result. It also generates energy saving activity advice for energy saving promotion and uses it as additional information. As a method for generating additional information, the energy saving evaluation means 4 is preliminarily registered with the energy saving evaluation index and explanations, advices, etc. according to the index numerical values. It may be configured to select information, or each time the energy saving evaluation means 4 creates an energy saving evaluation result, it may be configured to accept input of additional information from the outside through an input device or the like. It doesn't matter.

  In addition, although what kind of index is used to evaluate the energy usage amount collection result, an index related to energy saving activities that can be implemented by a building occupant is desirable. Also, when evaluating each index, compare the amount of energy used with the reference value and set the degree of contribution to energy saving so that the maximum value is “most energy-saving” or “most active in energy-saving activities”. It will be converted to a numerical value in 5 stages. In order to maintain fairness, this reference value is desirably set in the energy saving evaluation means 4 after being disclosed to an object to be evaluated (ie, a resident) and obtaining consent.

Here, energy efficiency, overtime reduction rate, zero standby power consumption exercise, indoor environment comfort, and natural energy utilization rate will be described as specific examples of indices.
Energy efficiency is evaluated in terms of energy intensity of air conditioning equipment and lighting equipment. The energy saving evaluation means 4 converts the energy basic units of the equipment and equipment collected by the energy usage totaling means 2 into numerical values so that the numerical value in five steps decreases as the basic unit increases.

  The overtime operation reduction rate is evaluated by the ratio of the overtime operation time to the core time of the air conditioning equipment or lighting equipment. The energy saving evaluation means 4 calculates the ratio of the overtime operation time to the core time by setting the five hours when the overtime operation time of these facilities counted by the energy usage totalization means 2 is 0 hours, and the ratio increases. The numerical value conversion is performed so that the numerical value in 5 steps decreases as the value increases.

  The zero standby power movement at night is the ratio of the daytime power of OA equipment that can be disabled at night to the total amount of power of OA equipment that can be stopped at night and OA equipment for 24-hour operation. evaluate. In other words, the lower the use of OA equipment for 24-hour operation and the smaller the difference in power consumption between daytime and all-day OA equipment that can be used at night, the higher the rating. The energy saving evaluation means 4 obtains the ratio from the energy usage totalized by the energy usage totalization means 2 and performs numerical conversion so that the numerical value in five steps increases as the ratio increases.

  The comfort of the indoor environment is evaluated using an index used in the evaluation relating to room temperature in “CASBEE-existing” of the overall environmental performance evaluation system for buildings. For example, the output value of the temperature sensor provided in the air conditioning equipment is input to the energy saving evaluation means 4, and the energy saving evaluation means 4 evaluates the indoor temperature situation every hour by a numerical value such as 1 point, 3 points, 5 points, etc. The average value is numerically converted into 5 levels.

  The natural energy utilization rate is evaluated by the ratio of the natural energy utilization operation time such as the outside air cooling exercise time to the air conditioning time of the air conditioning equipment. That is, the state in which air conditioning using outside air is performed is highly evaluated. For example, an air-conditioning operation time value obtained by counting the operation state of the air-conditioning equipment by a predetermined device and an outside-air cooling operation time value obtained by counting the outside-air cooling operation state are input to the energy-saving evaluation unit 4. The period when the ratio of the outside air cooling time in the season is large is set to 5 in 5 stages, and the numerical value is converted so that the value in the 5 stages decreases as this ratio decreases, and the outside air cooling time in the summer season (especially midsummer) is 0 hours. Time is set to 0 in 5 stages.

  The index may be other than these. For example, as an index corresponding to cool biz or warm biz, the difference between the temperature setting value of the air conditioning equipment and the reference value may be numerically converted into five stages.

  The evaluation result display means 5 generates a radar chart, a bar graph, etc. from the energy saving evaluation results digitized by the energy saving evaluation means 4 and displays them on the screen of a display device (not shown). Further, when receiving the selection operation from the input device, the additional information display means 6 displays the additional information generated by the energy saving evaluation means 4 on the radar chart or the like being displayed on the screen. The energy saving evaluation unit 4 and the evaluation result display unit 5 may present the energy saving evaluation result and the additional information on the screen of the display device to the resident as a printed matter.

Next, operation | movement of an energy-saving activity evaluation apparatus is demonstrated using the flowchart shown in FIG.
In step ST1, the energy usage amount acquisition means 1 acquires the energy usage amount of each equipment in the facility, and the energy usage amount aggregation means 2 totals according to a predetermined aggregation condition in units of evaluation groups such as tenants and departments. In addition, the process of step ST1 shall be performed in parallel also during the process of the following steps ST2-ST5.

  In subsequent step ST2, the energy saving evaluation means 4 periodically (for example, every month) uses the energy usage amount acquired and collected during the period to evaluate for each index and generate additional information.

  In subsequent step ST3, the evaluation result display means 5 displays the energy saving evaluation result on the screen as a radar chart or the like. FIG. 3 shows a screen display example of the energy saving evaluation result. In this example, based on the results of energy usage totaling for one month from January 1st to 31st, 2010, with the tenant of company Z as one unit of the evaluation group in the building A to be evaluated The result of energy saving evaluation is shown. In addition, there are five indexes for energy saving evaluation: energy efficiency, overtime reduction rate, zero standby power exercise at night, indoor environment comfort, and natural energy utilization rate.

  In subsequent step ST4, when a selection operation for an arbitrary index on the display screen of the energy saving evaluation result is input to the additional information display means 6 (step ST4 "YES"), the additional information display means 6 is the index for which the selection operation has been performed. Display additional information on the energy saving evaluation result of. In the example of FIG. 3, when the overtime driving reduction rate on the display screen is selected, the additional information display means 6 promotes energy saving activities that “please perform overtime driving only within a predetermined range”. Are additionally displayed on the same display screen as the radar chart. In addition, when an indicator with a low energy conservation evaluation result is selected and operated, it explains which part of the energy consumption is large, and what kind of energy conservation activities can be used to increase the energy conservation contribution. You may give advice. The additional information only needs to be visible at the same time as the radar chart. For example, the additional information may be displayed superimposed on the radar chart as shown in FIG. 3, or a “comment column” display area is provided below the radar chart. May be displayed, or may be displayed on a display device different from a display device that displays a radar chart or the like on the screen.

  As described above, according to the first embodiment, the energy saving activity evaluation apparatus obtains the energy usage amount acquisition unit 1 that acquires the energy usage amount of each facility device in the facility, and for each predetermined evaluation group that classifies each facility device. , For each evaluation group, according to at least one energy saving index that is registered in the energy saving index registration means 3 and energy usage amount counting means 2 that totals the energy usage according to a predetermined counting condition An energy saving evaluation means 4 for evaluating the energy saving contribution degree by quantifying the energy consumption total results in multiple stages, and an evaluation result display means 5 for displaying the evaluation results quantified by the energy saving evaluation means 4 as a radar chart on the screen. It comprised so that it might be equipped with. As a result, energy conservation evaluation results objectively evaluated using multiple energy conservation indices are presented not only to facility owners but also to facility residents, so the current situation regarding energy conservation, understanding current problems, The resident of the facility can also confirm the contribution level objectively. Therefore, it is possible to support each resident to raise their awareness of energy conservation activities and actively participate and continue, and as a result, it can be linked to energy conservation of the entire building.

  In addition, according to the first embodiment, the energy saving activity evaluation apparatus adds to the energy saving evaluation result being displayed on the screen, and information on at least one of the explanation of the evaluation result and the advice for increasing the degree of energy saving contribution. Is provided with additional information display means 6 for displaying the image. For this reason, it becomes easy to understand how the energy saving activity that the resident performed is reflected in the evaluation, and the evaluation result can be fed back to the energy saving activity.

  In the above description, the energy saving evaluation result is displayed on the screen as a radar chart. However, the present invention is not limited to this. For example, the bar graph as shown in FIG. 4 may be displayed as shown in FIG. A simple ranking table may be displayed on the screen. In the bar graph of FIG. 4, the horizontal axis indicates tenants A to D, and the vertical axis indicates each index value of each tenant. Thus, the same effect can be obtained even if the energy saving evaluation result is displayed on the screen as a bar graph.

  The ranking table shown in FIG. 5 is obtained by converting the bar graph of FIG. 4 into a ranking format. FIG. 5A is a ranking obtained by summing up five indexes, FIG. 5B is an energy efficiency ranking, 5 (c) is a ranking of the zero standby power movement at night. In this way, by ranking the evaluation groups based on the energy conservation evaluation results and showing them to the building occupants as a ranking table, the results of comparison with the energy conservation evaluation results of other occupants can be visualized. As a result, awareness of the people will increase and more active participation in energy conservation activities can be expected.
