摘　　要：设计前期作为建筑概念设计和方案设计的前置环节,其相关决策直接影响建筑全生命期碳排放水平.然而,设计信息和清单数据的匮乏,致使该阶段碳排放量化和设计优化面临着诸多困难.对此,本研究依据已有成果、案例统计和标准限额,构建了建筑设计前期全生命期碳排放预测模型,形成基于建筑高度和结构形式的隐含碳排放估算公式,以及不同能效等级及能源消耗模式下的运行碳排放量化指标.同时,整合涵盖“六化”设计策略等在内的各项降碳措施量化评估体系,从而为后续设计指明改进优化方向.本研究构建的建筑设计前期碳排放和降碳量预测方法能够有效指导建筑师在项目的设计前期阶段快速评估其碳排放总水平,明确降碳重点要素,最终实现建筑全生命期碳优化的源头把控.As a precursor to conceptual and schematic design,pre-design has a direct impact on the level of carbon emissions throughout the Whole-life of building.However,the lack of design information and listed data makes it difficult to optimise carbon emissions and reduce carbon emissions at this stage.In this regard,this study constructs a pre-design whole-life carbon emission prediction model based on existing studies,case statistics and standard limits,forming an implied carbon emission estimation formula based on building height and structural form,as well as an operational carbon emission index for each energy efficiency class and energy consumption mode.At the same time,a quantitative assessment system of carbon reduction measures,including the“six”design strategy,was integrated to indicate the direction of improvement for subsequent design.The prediction method of carbon emission and carbon reduction in the pre-design stage constructed in this study can effectively guide architects to quickly assess the carbon emission of the project in the pre-design stage,define the carbon reduction priorities,and ultimately achieve the source control of carbon optimisation in the whole life cycle of the building.
