The personal computer 6 is connected to the processing means 4 via the Internet 7 and can exchange data mutually, and the processing means 4 is connected to the storage means 3 to exchange data mutually.

The input means 2 and the output display means 5 are provided adjacent to the storage means 3 and the processing means 4 to form an integrated energy-saving diagnostic apparatus 1 for a building or the like. It is convenient that the personal computer 6, which also serves as the means 2 and the output display means 5, is connected to the processing means 4 via a communication line such as the Internet 7.
In this case, it is considered that the personal computer 6 is almost the one for the building diagnosis applicant.

FIG. 2 is a flow chart for explaining the flow of data processing. In this embodiment, the input data is input in three stages of step 11 to step 13 as shown. First, when a person requesting a building diagnosis accesses a diagnosis item on the home page, in step 11, a display prompting the customer to input customer data is displayed on the display screen of the personal computer 6. Specifically, "company name / department",
“Name”, “address”, “E-mail address”, and “telephone number / facsimile number”. Of these,
Some items are required to be input, and if there is no input,
The configuration may be such that the subsequent processing cannot be continued.

Next, in step 12, a display prompting the user to input equipment / energy data is displayed on the display screen of the personal computer 6. Specifically, "building name", "location / building use", "scale / total floor area", "annual energy consumption", "electricity / gas / oil type", "contract electricity", "heat source / Air-conditioning system ".

Of these, for example, in the case of building use, "office", "hospital", "hotel", "school",
The items of "department store", "public office", "entertainment facility", and "other" are displayed, and the corresponding items are clicked. In the case of annual energy consumption and electricity, a blank is provided to input the value of kWh / year.

Even in this step 12, some of the items are required to be input, and if there is no input, the process after this may not be continued. It should be noted that the purpose of this step 12 is to obtain data for determining what level the energy consumption of the building or the like of the building diagnosis applicant is relative to the average value of the building for the same purpose.

Next, in step 13, a display prompting the user to input the energy saving efforts is displayed on the display screen of the personal computer 6. Specifically, "adoption of ice heat storage", "adoption of inverter", "adoption of outdoor air cooling", "adoption of all heat exchange", "setting of cooling and heating temperature", "air conditioning operation time", "light off during lunch break", Etc.

At the end of 3, although not shown in the figure, an input means for listening to the request of the building diagnosis applicant may be provided. For example,
"A: I'm interested in saving energy in buildings
There is no explanation and I want you to contact me. "," B: Send me related materials "," C: Contact me / Reply via E-mail. "," D: There is no problem in the current situation. " Use the input method to click the one you want to click.

In FIG. 2, the primary energy consumption is calculated from the data input in steps 12 and 13 (step 14). A specific algorithm for the calculation is performed by the processing means (server) 4 by a conventional method.

Next, the average value of energy consumption of buildings by the Japan Building Energy Management Technology Association is compared with the target project (primary energy consumption) (step 15). The average value of energy consumption for each application is read from the storage means (database) 3. Data of the total energy consumption unit for each building use as shown in the table of FIG. 3 is accumulated in the storage means 3 and can be read out by a command from the processing means 4. The table of FIG. 3 shows two types of data, “average value” and “simple average value”, but which one is used is determined according to the application.

In addition to the data illustrated in the table of FIG. 3, the storage means 3 stores, for example, data such as regional energy consumption and seasonal energy consumption. It is readable. For example, data on heating and cooling in winter in Kagoshima prefecture can be read.

The comparison between the average value of the energy consumption for each application and the target case is performed by the processing means 4 by a conventional method. Based on the comparison result, the energy saving diagnosis result is determined and output on the screen of the personal computer 6 which is the output display means 5 (step 16).

In this embodiment, the judgment result of the energy saving diagnosis result is classified into five types. When the energy consumption of the target project is less than 90% of the average value for each building use (step 17), the diagnosis result is “excellent” (step 18). When the energy consumption of the target project is 90% to less than 110% of the average value for each building application (Step 1
In 9), the diagnosis result is said to be “good” (step 20). When the energy consumption of the target project is less than 110% to 130% of the average value for each building application (Step 2
In 1), the diagnosis result is "normal" (step 22). If the energy consumption of the target project is less than 130% to 150% of the average value for each building application (Step 2
In 3), the diagnosis result is "partially required improvement" (step 24). When the energy consumption of the target project is 150% or more of the average value for each building use (Step 2
In 5), the diagnosis result is "Please contact us once" (step 26).

As described above, the diagnosis result is output to the screen of the personal computer 6 only by inputting the information of the person who desires the building diagnosis through the Internet, and the energy saving diagnosis result of the building or the like can be easily and quickly obtained. The person who desires to diagnose the building can obtain the guideline for energy saving measures, renewal of the building, etc. In addition, the present embodiment is merely an example, and the present invention can take various aspects without being limited thereto.
