建筑碳排放预测信息集成技术研究

Information Integration Technology of Building Carbon Emission Prediction

BIM技术在建筑全生命周期碳排放预测中还未得到充分应用。本文首先根据建筑碳排放预测信息需求,提出建筑碳排放预测信息集成架构;其次,基于IFC标准与gbXML数据格式,建立集成的建筑碳排放预测信息模型CeData,并提出项目信息子模型CeData_Pro、热工分析子模型CeData_Ther、能耗监测子模型CeData_Mor和碳排放子模型CeData_Coe四个子模型的信息结构。CeData可在BIM环境中高效获取和传递信息,为建筑碳排放预测系统的研发提供了信息基础。

This study first proposes an information integration framework of building carbon emission prediction,based on the demand for building carbon emission prediction information.Secondly,based on the IFC standard and gbXML data format,this study establishes an integrated building carbon emission prediction information model CeData,and the information structure of four sub-models(project sub-model CeData_Pro,energy monitoring sub-model CeData_Mor,thermal analysis sub-model CeData_Ther and carbon emission sub-model CeData_Coe).Information of CeData can be efficiently obtained and transmitted in the BIM environment,providing an information foundation for the research and development of the building carbon emission prediction system.
