Development of an ontology for construction carbon emission tracking and evaluation

Significant carbon emissions from construction sites necessitate improved management through integrating diverse data sources. Ontologies are widely employed for data integration but there is an absence of domainspecific ontologies for carbon emissions management during construction. We developed a Carbon Emission Management Ontology (CEMO) utilizing a hybrid development approach. CEMO comprises eight modules, namely Project, Quantity of Works, Environment Parameters, Agents, Equipment, Observation, KPI, and Calculation. To assess its efficacy, CEMO was evaluated by experts based on criteria such as clarity, coverage, consistency, and extensibility. The feasibility and effectiveness of CEMO were demonstrated through a case study, showcasing its utility in carbon intensity calculation and evaluation of earned carbon value. CEMO facilitates seamless integration of data from disparate sources, enabling real-time and automated management of onsite carbon emissions as well as disclosure of carbon-related information.
