노후 건축물의 그린 리모델링 계획을 위한 온톨로지 기반 의사결정 지원 모델

Abstract

Green remodeling projects are being activated to improve the energy performance of old buildings. However, the construction industry is having difficulty sharing knowledge and data management due to differentiated work and wide knowledge gap between stakeholders. Therefore, before performing green remodeling, an objective decision-making method that proposes technology is needed. In this study, an ontology-based model is proposed to support the green remodeling plan. Ontology collects various information existing on the web. Information is expressed and inferred in a human way of thinking to derive results. As a result, accurate data-based information can be searched and differences in interpretation according to individual evaluation can be reduced.

The research progress is as follows. Data is classified by collecting information on old buildings through the building register. The classified data is divided into standard module, core module, and condition module. The module is determined by grasping the effect of the collected data on energy performance improvement. Next, data relationships are organized through Protégé and converted into ontology. The converted information is stored on the web and searched within metadata.

In order to verify the usability of the developed model, a search was conducted for cases where actual green remodeling was performed. As a result, data that were remodeled to the grade desired by the user were derived. The result data can be selected according to the needs of stakeholders participating in the project and the green remodeling project can be carried out.
