Abstract
Many problems and issues affect the green construction process. Inaccurate assessment is one of the important factors for green construction. The objective of this study is to propose a BIM and ontology-based approach that enables the evaluation information of green construction to be inferred from a knowledge base in order to achieve scheme optimization. To automate the inference, this study established the BIM ontology that consists of BIM shared ontology and BIM construction ontology. First, IFC extension is adopted in green construction assessment system to generate attribute sets. IFC-based parameters stored in BIM models are mapped to OWL and will be used as the data source of the evaluation indicators. Then, BIM-shared ontology and BIM construction ontology are defined. Protégé is employed to simulate the evaluation indicator system. Last, utilizing BIM knowledge base, through the construction of SWRL rule language and the Drools inference, the scores of evaluation indicators could be obtained. The experimental results demonstrated that BIM knowledge base for the evaluation of green construction could realize the sharing, maintenance, and acquisition of knowledge among different participants of the project and improve the management of green construction. The proposed ontological inference of evaluation item enables an automated search of the aspects needing improvements in green construction and assist project managers in using BIM data more easily and effectively.

Green construction is the application of sustainable development idea in the AEC industry. e traditional construction method is to achieve the project quality, schedule, and cost as the basic goal [4]. e resource conservation and the environmental protection get less focus in the construction stage, while green construction emphasizes the efficient use of resources as the core and the environmental conservation as the priority principle in order to pursue the integrated construction method with the high efficiency, low consumption, and environmental protection [5]
Summary
Sustainability in the AEC (architecture, engineering, and construction) industry has gained popular momentum over the past decades to enable all people to meet their basic needs and improve their quality of life while saving our natural resources and diversity [1]. By virtue of its size, the construction industry is one of the largest users of energy, material resources, and water, and it is a formidable polluter [2]. Green construction is defined to ensure quality, safety, and other basic requirements and adopt scientific management and technological progress in the process to maximize the conservation of resources and reduce the construction activities which will bring negative impacts on the environment [3]. Architects, designers, engineers, and others involved in the construction process have their opportunities to reduce environmental impacts through the implementation of sustainability objectives
