Research On Intelligent Assistant Green Building Evaluation Based On Ontology And BIM

As a pillar industry of national economy,construction industry has brought a series of environmental problems,which calls for strategies of transformation development.Therefore,green building and its evaluation system come into being.The implementation of green building evaluation requires both evaluation standard and building information,and the traditional green building evaluation relies on manual operation itself would be not only laborious and time-consuming but also very error-prone due to more and more complicated building structure,huge amounts of the whole life-cycle building information,inefficient storage mode of current standard knowledge,limited experience and deficient energy of evaluation personnel as well as changeable standards.In BIM model,all the information during the whole life cycle of construction can be integrated and domain ontology can take structured organization to domain knowledge to achieve knowledge sharing and reuse.In order to share and reuse the information in Green Building Evaluation Standard GB/T50378-2014 and to solve the consuming,laborious and error-prone issues emerged in manual green building evaluation process,an intelligent green building evaluation system based on ontology and BIM is proposed after analyzing the details in this criteria.The main contents are as follows:? Based on knowledge management theory,ontology theory and some other relevant research,a domain ontology model is formulated to realize the structured organization of legal knowledge and then achieve knowledge sharing and reuse.? Based on the research of green building and its evaluation criterion system and BIM technology,specific provisions contained in Green Building Evaluation Standard GB/T50378-2014 is analyzed,classified and summarized by making use of BIM technology to obtain green building evaluation index.? According to the analysis of ontology-based knowledge management and BIM-based green building evaluation system,an intelligent green building evaluation system based on ontology and BIM is proposed to describe the specific establishing process of GBEvaluatingOntology in the ontology model.? According to parts of the details in Green Building Evaluation Standard GB/T50378-2014,a green building evaluation toward a certain building is carried out to verify the feasibility and validity of the intelligent green building evaluation system established above.The feasibility and validity of the intelligent green building evaluation system designed in this paper is validated through a practical example.The intelligent green building evaluation system based on ontology and BIM proposed in this paper can not only remedy evaluation personnel's shortage of limited experience and deficient energy but also decrease the occurrence of consuming,laborious and error-prone issues in manual green building evaluation process.
