Description

  The present invention relates to a system for evaluating the value of real estate.

Conventionally, a method for evaluating the value of a building has been adopted in which the quality of the entire building is evaluated. In the real estate securitization rating method,
(i) Market analysis such as location conditions, competitive property status, tenant supply and demand trends
(ii) Considering the quality of the target real estate such as the environment, building contractor, economic life and building age, in the case of offices and commercial facilities, the quality of asset management and the status of tenants are also evaluated as evaluation points. . Even in such an evaluation method, the quality of the entire building is an evaluation target in a broad sense.

  In recent years, more accurate evaluation results have been required for such value evaluation. With regard to real estate securitization in particular, the development of laws such as the Special Purpose Company (SPC) law, revision of the real estate tax system, review of real estate valuation methods, etc. are progressing rapidly. With such real estate securitization, several financial products have been born. One example is a real estate investment trust called REIT (Real Estate Investment Trust). In order for such financial products to become established with a wider range of investors, it is required that the value evaluation of real estate such as buildings will be more accurate than before.

  By the way, in order to more accurately evaluate the value of a building, it is considered effective to return to the building members constituting the building, perform value evaluation, and make a value judgment by a method of accumulating the value of each building member.

However, in the conventional property value evaluation, individual management of each building member is not normally performed, and it is practically impossible to perform the value evaluation as described above. The number of building elements that make up a building is usually enormous, and the description is substantial. It was practically impossible to assess the asset value of these building components individually and evaluate the value of the building by stacking them. For example, Patent Document 1 describes a conventional fixed asset management system using a computer. In such a system, a large number of fixed assets and their useful lives are registered in the storage device, but when registering, the relevant useful lives must be entered manually while checking against a written ledger. The problem of requiring a lot of labor and cost has been pointed out.

It is effective as an embodiment.

  ADVANTAGE OF THE INVENTION According to this invention, the system which accumulates management for every building member and implement | achieves the maintenance of the whole building is provided.

1st Embodiment The system which concerns on this embodiment arrange | positions an ID tag in a building member, and even after building a building using the member, it is the age of use, a deterioration state, and amortization for every building member. Information can be managed.

  FIG. 1 is a flowchart showing a usage mode of an ID tag according to the present embodiment. The following processing is performed in the building material manufacturer. First, asset information (also referred to as “product information” in FIGS. 1 to 4) related to the building member is written in the ID tag (S102). The asset information includes basic data for calculating the value of the building member and the identifier of the building member. Information is written by a predetermined reader / writer.

  Next, an ID tag storing predetermined information is arranged on the building member (S104). The member provided with the ID tag is packed in a predetermined package and shipped (S106).

  The purchaser of the building material receives the building member from the shipping source and receives the asset information table of each building member (S108). The asset information table has the same content as the asset information written in the ID tag, and is in a form in which the set of building members is summarized. FIG. 2 is an example of an asset information table. The member name, asset information, and purchase information are written in association with the ID tag management number.

  In the figure, the service life indicates a standard service life determined for each member. The data written in the ID tag in step 102 is data corresponding to each row in FIG.

  Subsequently, a building member is installed in a predetermined place (S110).

  After installation, asset information in each ID tag is read using a handy terminal type or stationary type ID tag reader. The reader / writer has a GPS function, and acquires the position information of the ID tag along with the asset information. These pieces of information are taken into a predetermined server in a form associated with each other and recorded in the information table (S112). FIG. 3 is an example of such a table. As described above, the position information of the ID tag is associated with the asset information.

  Thereafter, ID tag information is read and written during periodic inspections and abnormal inspections (S114). For example, together with the ID tag information, it is also possible to acquire position information where the ID tag is arranged, perform data processing in association with these, and detect an abnormality in a building or a building member.

  When the building member is repaired (S116), the repair contents are written in the above-mentioned table (S118).

  When the building member is replaced (S120), the ID tag and the building member are removed from the site, and the fact that the building member has been replaced is written on the table (S122).

  In the information table, such usage status is written as needed, and asset information is additionally written. FIG. 4 shows an example of a table to which such information is added.

  The removed building member is disposed of after removing the ID tag. The removed ID tag is discarded after being invalidated (S124). It is good also as reproducing | regenerating without discarding.

  FIG. 5 is a diagram illustrating an example of the configuration of the real estate management system according to the present embodiment.

  The ID tag 102 is arranged on each building member to be managed by this system. The ID tag 102 stores asset information of the building member. The asset information consists of data shown in FIG. 2 as already described. Note that the information stored in the ID tag 102 can be updated at any time. For example, when a building member is repaired, the information is written in the ID tag 102.

  The portable terminal 104 is a reader / writer that reads and writes information stored in the ID tag 102. The portable terminal 104 has a GPS function, and when reading information in the ID tag, it also obtains information regarding the position where the ID tag 102 is disposed at the same time. Thereby, the position information of the ID tag 102 and the information stored in the ID tag 102 are acquired in the associated form in the portable terminal 104 and stored in the ID tag information DB 108 via the ID tag data receiving unit 106. The The mobile terminal 104 may be mobile or fixed.

As a specific example of the combination of the ID tag 102 and the mobile terminal 104, an example in which an RFID tag is used as the ID tag 102 and a fixed or mobile reader / writer is used as the mobile terminal 104 can be given.
The present invention uses an ID tag as a means for grasping the position of an article as well as tracking the article over time. This makes it possible to grasp the position of a spatially dispersed member at a stage after construction and to track the member over time.
However, in order to enable such grasping (operation / management), it is necessary to solve the following problems in the real estate field where the building members are arranged.
(i) Arrangement of building members has a spatial (three-dimensional) spread within the asset (building).
(ii) The so-called “set” of the procured building components have various spatial expansions, such as A building, B house, C bridge, as well as specific assets (buildings). Being.
In order to enable tracking management (traceability) of building members while solving the above two problems, the present invention employs ID tag information acquisition means. As a configuration for realizing such a scheme, there is a combination of an RFID tag and a fixed or mobile type ridder. By carrying out like this, the log | history can be grasped | ascertained reliably about the building member spatially arrange | positioned.
For example, if the UHF band is used as the frequency range of the RFID tag, the detection range by the reader / writer is several meters. For example, by installing one or several mobile terminals 104 in one room, the building in the room It becomes possible to manage the members.

  When the ID tag 102 is an RFID tag, for example, a power supply circuit, a radio frequency (RF) circuit, a modulation circuit, a demodulation circuit, a CPU, and a memory connected to the CPU can be used. The power supply circuit includes a capacitor, and this capacitor forms a resonance circuit together with the tag antenna. When the tag antenna receives radio waves of a specific frequency (frequency at which the resonance circuit resonates), the capacitor is charged with electric power generated by the mutual induction effect. The power supply circuit rectifies and stabilizes this electric power, supplies it to the CPU, and activates the IC chip. The memory reads data stored in response to a read command by radio wave data communication from the reader / writer under the control of the CPU. Further, data is written into the memory in accordance with a write command from the reader / writer.

  Information stored in the portable terminal 104 is sent to the ID tag data receiving unit 106 by the operator, and the ID tag data receiving unit 106 stores the information in the ID tag information DB 108. An example of the stored information is shown in FIG.

  The purchaser 114 acquires asset information of the building member at the time of purchasing the building member and inputs it to the member information receiving unit 116. The member information receiving unit 116 stores the received asset information in the detailed information DB 110. This asset information is the same as that stored in the ID tag 102 and comprises data shown in FIG.

  The asset information DB 112 includes an ID tag information DB 108 and a detailed information DB 110, and is configured as a relational database using an ID tag management number as key data. The asset information DB 112 can be accessed at any time by the user 118 and is used for building management.

  The information processing unit 120 accesses asset information stored in the asset information DB 112 in response to a request from the user 118 and performs processing such as asset evaluation. The evaluation result is presented to the user 118 by the output unit 122.

  FIG. 6 is a diagram illustrating the internal configuration of the information processing unit 120 in detail. The information processing unit 120 includes a building member evaluation unit 160 and a real estate evaluation unit 162.

  The building member evaluation unit 160 accesses the asset information storage unit in response to a request from the user 118 and acquires asset information of each building member. And the value of a building member is calculated based on this asset information. Specifically, the value is calculated according to a predetermined mathematical formula taking into account the service life, depreciation rate, repair information, and the like. Building member evaluation data is created by associating the calculated value with an identifier corresponding to the building member.

  The real estate evaluation unit 162 calculates the value of the real estate based on the building member evaluation data. That is, the total sum of building material evaluation data is obtained, and the value is calculated in consideration of this, the environmental index, the real estate distribution index, and the like.

The user 118 can perform, for example, the following real estate value evaluation by using the asset information DB 112.
(i) Real estate value evaluation
(ii) Property tax calculation
(iii) Insurance premium calculation In performing these property value evaluations, a standard for evaluation and calculation is required. This system is configured to obtain such standards from the real estate value evaluation standard DB 150, the tax calculation standard DB 152, and the insurance premium calculation standard DB 154 connected via the network. That is, the information processing unit 120 and the member information receiving unit 116 acquire necessary information from a predetermined database via the transmission / reception unit 124.

  The system shown in FIG. 5 has a configuration in which a plurality of real estate management apparatuses 100 are connected via a network. Each real estate management apparatus 100 has the same configuration and includes an asset information DB 112. The asset information DB 112 holds durable data including data on the usage status of building members and data indicating a period from the start of use to member replacement. An arbitrary real estate management apparatus 100 configuring the management system shown in FIG. 5 is configured to access the asset information DB 112 of another real estate management apparatus 100 and use the durable data. This makes it possible to share information on building materials and realize efficient real estate value evaluation.

  According to this embodiment, by using an ID tag attached to each building member, real estate value evaluation can be performed for each building member, not for the entire building. Furthermore, even when a building member is repaired or replaced, real estate value evaluation that reflects such maintenance information becomes possible. In the conventional building material management system, it is difficult to grasp how and where the purchased member is used and in what state. In this embodiment, the building can be managed for each building member by attaching an ID tag to each building member and providing traceability.

That is, in this embodiment, since the ID tag 102 is attached to each building member, it is possible to perform a new real estate value evaluation that has not been conventionally performed. Conventionally, the specifications of building materials have been received collectively in order units, and such information is usually stored in the form of documents without being digitized. Moreover, once a building member is actually assembled and incorporated into a building, it has been virtually impossible to manage the building member thereafter. This is because it was impossible to grasp how and where the building members are arranged in the building. As a result, it was virtually impossible to reflect the information when repairing or replacing building components. On the other hand, according to the structure of this embodiment, the information of the building member can be acquired at any time via the ID tag arranged in each building member. Even after being taken into the building, the position information of the building member can be grasped. For this reason, it is possible to realize a precise real estate value evaluation in which management objects are subdivided into building material units. Furthermore, since the repair information of the building member and the actual useful life of the building member can be accurately reflected, the accuracy of the real estate value evaluation can be improved from this point.
As described above, according to the present embodiment, a technical scheme is realized that not only has the value information of individual assets but also enables unified management and analysis thereof.

Second Embodiment In the present embodiment, a configuration example of the real estate management apparatus 100 that quickly responds to various processing contents by including a plurality of modules is shown.

  FIG. 7 is a diagram illustrating a configuration example of the information processing unit 120 in FIG. The user 118 accesses the processing mode reception unit 172 and designates a desired processing mode. For example, real estate value evaluation in investment trust, real estate value evaluation in building sales, real estate value evaluation for determining property tax, real estate value evaluation for insurance premium calculation, and the like.

  The processing mode reception unit 121 assigns a processing code to the requested processing according to these evaluation contents. The processing code is sent to the calculation standard collection unit 174 and the classification code designation unit 176. The calculation standard collection unit 174 acquires standards and mathematical formulas necessary for calculating the evaluation result with reference to the asset information DB 112 or the DB in the external device connected via the network. On the other hand, the classification code specifying unit 176 refers to the processing code and extracts the building member that is the target of the requested processing from the asset information DB 112. In the extraction, the classification code assigned to each building member is used as a key, and the association table between the processing code and the classification code associated in advance is referred to. This table is held in the asset information DB 112. The calculated evaluation result is presented to the user 118 via the output unit 122. For example, even for the purpose of real estate value evaluation, the target range is different between value evaluation in real estate securitization and value evaluation for fixed asset tax calculation. As described above, by assigning a classification code to each building member and extracting an evaluation target using the classification code as a clue, efficient processing becomes possible.

  According to this embodiment, the minimum necessary data is accessed according to the processing code, and the result is output. For this reason, a quick and efficient process can be performed.

Third Embodiment FIG. 8 is a diagram illustrating another modification of the information processing unit 120. The information processing unit 120 includes a module group 170 and is configured such that an appropriate module is activated according to the processing content requested by the user. Here, the term “module” is used in a broad sense including systems, devices, apparatuses, components, programs, subprograms, processes, and the like.

  The user 118 gives the processing content to be executed to the processing mode reception unit 121. The processing mode reception unit 121 receives this instruction, converts it into a predetermined format, and sends the data to the module selection unit 138. The module selection unit 138 selects a processing module suitable for the received processing mode.

  The module group 170 includes a repair plan creation module 128, a real estate value evaluation module 202, a tax / insurance calculation module 204, and an asset management support module 206.

  For example, when executing a repair plan creation support process, a command is issued to the repair plan creation module 128 and subsequent processes are performed. As shown in FIG. 4, the asset information DB 112 stores data on the date when the building member was repaired and the useful life of the building member. The repair plan creation module 128 calculates a recommended repair time for the building member in consideration of the date of repair and the useful life.

  Further, when the real estate value evaluation process is performed, a command is issued to the real estate value evaluation module 202 and subsequent processes are executed. Since real estate value evaluation has different processing contents depending on the contents to be evaluated, the processing is executed as described in the second embodiment.

  In addition, in the case of tax / insurance calculation processing, the tax / insurance calculation module 204 is specified, and in the case of asset management support processing, the asset management support module 206 is designated to perform subsequent processing.

  According to the present embodiment, a processing module is selected according to the processing mode, and each processing module accesses the minimum necessary data according to the processing content and outputs the result, so that excellent processing efficiency can be obtained. it can.

Fourth Embodiment FIG. 9 shows the configuration of a management system according to this embodiment. This system has a configuration in which a plurality of real estate management apparatuses 100 and information management apparatuses 200 are connected via a network. Although two real estate management apparatuses 100 are shown in the figure, a large number of real estate management apparatuses 100 may actually be included.

  The real estate management apparatus 100 employs the configuration already described in the above embodiment. The member information storage unit in the real estate management apparatus 100 holds durability data including data relating to the usage status of building members and data indicating a period from the start of use to member replacement.

  The information management apparatus 200 includes therein a transmission / reception unit 142, a data processing unit 144, a data storage unit 146, and a database control unit 148. The information management apparatus 200 collects various pieces of information regarding building members acquired by the real estate management apparatus 100 via a network, processes them into a predetermined format, generates basic data for asset evaluation, and stores the data as data storage Stored in the unit 146. The basic data for asset evaluation is, for example, data including a useful life, characteristics, a depreciation rate, etc. in consideration of the actual usage of building materials, and is basic data for evaluating the asset value of building materials.

  For example, if you try to place a building member at a certain place in the building, obtain information such as how long the member can be used in the usage environment and how it will deteriorate. Is desired. Conventionally, the service life is uniformly determined for each building member, and it has been difficult to obtain information on how the service life fluctuates depending on the use environment and the like. On the other hand, according to the configuration of the present embodiment, what kind of service life is exhibited at the site where the member is actually used is acquired as performance data, so objective and rational real estate evaluation is performed. It becomes possible.

  The data stored in the data storage unit 146 is used in various forms according to the user's request. The user accesses the information management apparatus 200 through the real estate management apparatus 100 and requests predetermined information. This request is received by the transmission / reception unit 142 and transmitted to the database control unit 148. The database control unit 148 extracts data from the data storage unit 146 in response to such a request, and sends the extracted data back to the transmission / reception unit 142. The transmission / reception unit 142 transmits the extraction result to the requested 126 via the network.

  The type of data stored in the data storage unit 146 is not particularly limited, and various data may be stored in addition to the asset evaluation basic data.
