Building Facility Value Evaluation from Maintenance Service Records
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing real-estate valuation methods fail to evaluate the economic values of facilities in large buildings such as elevators and air-conditioning systems, which vary based on maintenance management services like repairs and inspections, despite their impact on facility conditions.
Innovation Solution
A facility evaluation apparatus and method that accesses service record and evaluation criterion information to determine facility values based on maintenance management service data, including lapse of time, number of services, and frequency, using rules to assess operational periods and conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing real-estate valuation methods are used, then prices of land and buildings can be evaluated, but values of facilities cannot be evaluated
Solution Approach 1:
The valuation process is segmented into separate components: land evaluation, building evaluation, and facility evaluation. Each component has its own evaluation method and criteria, allowing facilities to be independently assessed based on their specific characteristics and maintenance histories
Solution Approach 2:
The invention introduces new evaluation parameters specific to facilities, including maintenance service records, operational status, age, and condition. These parameters transform the evaluation from a generic real-estate approach to a specialized facility assessment that captures the unique value factors of building facilities
2Measurement precision
If facilities are not evaluated, then real-estate appraisal is simpler, but comprehensive value assessment is incomplete
Solution Approach 1:
The evaluation system is designed to handle multiple evaluation types (land, building, and facility) within a unified framework. The facility evaluation module can be integrated with existing real-estate valuation processes, allowing the system to perform comprehensive assessments without requiring entirely separate procedures
Solution Approach 2:
Maintenance service records and facility condition data are collected and stored in advance through building management systems. This preliminary data gathering enables the evaluation system to access ready-made information about facility maintenance histories, operational status, and condition, reducing the complexity of real-time assessment
3Measurement precision
If facility conditions are not considered, then evaluation is faster, but value determination is inaccurate
Solution Approach 1:
The evaluation system incorporates feedback loops that continuously update facility condition assessments based on maintenance service records and operational data. This feedback mechanism ensures that the most current facility status is reflected in the value determination, improving accuracy while using pre-collected data to minimize time loss

AI summary
A service-record information item about one maintenance-management service, the service-record information item being stored in a service record DB, includes first information about a date on which the one maintenance-management service was provided. An evaluation-criterion information item about one facility, the evaluation-criterion information item being stored in a facility evaluation DB, includes a value determination rule according to which an evaluation value that indicates a value of the one facility is determined. According to the value determination rule for the one facility, the evaluation value of the one facility is determined on the basis of an at least one of a lapse of time since provision of an at least one maintenance-management service that is possible to provide to the one facility, the number of times of the provision, and a frequency of the provision.
