| dc.description.abstract | Due to the increasing amount of human activities, global warming is becoming more and more serious, further causing climate abnormalities around the world, heightening awareness of energy saving and carbon reduction, and making people pay attention to improve environmental degradation. The carbon emissions generated by construction projects have always been one of the main parts of Taiwan ’s total carbon emissions, so the government continues to promote energy conservation and carbon reduction plans for different projects. The Environmental Protection Agency passed the “Greenhouse Gas Reduction and Management Law”in 2015, the first law related to climate change in Taiwan, with a view to reduce carbon emissions during construction.
In order to improve the calculation efficiency of carbon emissions, this study takes an embankment project as the object, and applies ontological modeling technique to clearly present the carbon emissions of various work items in the embankment project for assisting designers in estimating the carbon emissions. After analyzing the embankment project case, classifications for activity and the resource items are developed in an ontology; the specifications, quantities and carbon emission coefficients of each machinery and material are then represented as class properties, and the carbon emission calculation rules are defined using SWRL and SQWRL inference rules. The built ontology model includes a carbon emission representation framework and carbon emission calculation inference rules for the embankment project, so that users only need to input the quantity of an operation to calculate the total carbon emission of a project. This model can be quickly applied to other similar projects and can be reduced the time required for the emission assessment at the design stage can be reduced.Testing and comparing with the time required for past carbon emissions calculations, proceeding to actually combine carbon emissions with the problems faced by ontology. The results show that although the method of this study takes time for first-time users to learn, compared with other methods, the use of it will improve the designer′s computing efficiency. | en_US |
