Field of the Invention The present invention measures the amount of energy such as electric power, gas, and water supplied to each tenant in a building in which a plurality of tenants live and measures the amount of energy used. The present invention relates to a building management device that charges usage fees to each tenant.

[0002]

2. Description of the Related Art In a building in which multiple tenants live, electric power companies, gas companies, and water supply companies charge the usage fees for energy such as electric power, gas, and water supplied to each tenant. Install a former meter that measures the usage of the entire building without billing, and bill the building manager such as the building owner or building management company who manages this building with a usage fee according to the usage of this original meter. There is also.

In such a building, a meter is installed for each tenant, and the building manager checks the amount of energy used by each tenant, such as electric power, gas, water, etc. The billed amount was distributed to each tenant and charged according to the usage amount.

Therefore, each tenant may pay, for example, the usage fee stated in the bill sent from the building administrator at the end of the month to the building administrator. Naturally, the usage fee and the usage amount are described in this invoice.

[0005]

[Problems to be Solved by the Invention] However, some tenants occupying a building may use a large amount of electricity, gas or water such as a restaurant, or tenants or mechanical equipment operating overnight. Some tenants are in operation. For such a tenant, the ratio of the usage charge of electricity, gas, and water used for each month to the total cost is significantly higher than that of a general office.

Therefore, each tenant sees the bill sent at the end of the month, and for the first time confirms the usage amount and usage fee of electricity, gas, and water for this month, so that the usage fee is higher than expected. In some cases, payment may be difficult.

The present invention has been made in view of such circumstances, and by constantly monitoring the usage amount of the meter attached to each tenant, even during the prescribed period which is the issuance period of a bill. It is an object of the present invention to provide a building management device capable of notifying a usage amount and a usage fee at this point in time in response to a request from a tenant and significantly improving services for the tenant.

[0008]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides an amount of energy including at least electric power measured by a meter attached to each tenant in a building in which a plurality of tenants reside. In a building management device that aggregates each predetermined period for each predetermined period and bills each tenant a usage fee for the corresponding period, a meter monitoring unit that monitors the usage amount of each meter installed in each tenant, A measurement value buffer that stores and holds the usage amount of each meter for each unit cycle that is shorter than the specified cycle, and a transmission request acceptance unit that accepts a transmission request of the usage amount transmitted from the information terminal installed in each tenant via the network. And the accumulated amount of usage and usage charges from the start of the specified cycle to the reception of the transmission request, the usage and charge tables stored in the measurement value buffer. An intermediate progress calculating means for calculating as an intermediate progress, and an intermediate progress responding means for responding to the information terminal of the transmission request source via the network with the intermediate usage progress and usage charge calculated by the intermediate progress calculation means. It is equipped with.

In the thus constructed building management apparatus, the energy consumption of each tenant is stored in the measured value buffer for each unit cycle such as one day shorter than the prescribed cycle such as one month. . Therefore, when the usage request is received from each tenant, the usage amount and usage charge from the start time of the specified cycle to the current time is calculated using each usage amount stored in this measurement value buffer for each unit cycle. It is possible to send the integrated value as the progress to the tenant who requested the transmission.

Therefore, each tenant can confirm the progress of the usage amount and usage fee in the middle of a prescribed cycle such as one month.

Another aspect of the present invention is the building management device of the above-mentioned invention, further comprising a record database for storing the past record value in the usage amount and charge for each unit period and for each specified period for each tenant. And an actual value attaching means for attaching the usage amount and the usage charge for the corresponding period stored in the performance database to the progress of the usage amount and the usage charge responding to the information terminal of the transmission request source.

In the thus constructed building management apparatus, the tenant can compare and contrast the progress of the usage amount and the usage fee with, for example, the usage amount and the usage fee in the same period last month or the previous year.

Further, in another invention, a user ID for identifying a tenant to which each information terminal belongs is attached to each information terminal in advance, and the user ID and the password are used when receiving a transmission request of the usage amount from each of the information terminals. I am trying to confirm.

In the building management device thus configured, it is possible to improve operability and safety in information exchange via the network between the information terminals of the respective tenants and the building management device.

The usage amount is stored and held in the measurement value buffer 12 for each unit cycle such as one day shorter than a prescribed cycle such as one month. In addition, the past daily and monthly actual data of each tenant 3 is stored and retained in the actual result database 11.

Therefore, when the usage amount transmission request 29 is received from each of the tenants 3, the usage amount for each day stored in the measured value buffer 12 is used to start from the start time of one month to the present time. It is possible to transmit the integrated value of the usage amount and the usage charge as the midway progress 30 to the tenant 3 that is the transmission request source. In addition, it is possible to reply together with past usage data and usage fee data for the same period.

Therefore, the person in charge of each tenant 3 (employee)
Using the information terminal 9 of its own, it is possible to confirm the progress of the usage amount and usage fee in the middle of a prescribed cycle such as one month. Further, the tenant 3 can compare and contrast the progress of the usage amount and the usage fee with, for example, the usage amount and the usage fee in the same period of the last month or the previous year. As a result, it is possible to predict the billing amount at the end of the month and adjust the daily usage amount until the end of the month.
