以设计为导向的建筑生命周期碳排放计算体系与方法研究

Predicting building life cycle carbon emissions during the building design process and designing carbon reduction based on this is an effective means of reducing building carbon emissions. Existing building carbon emissions calculation methods are “product-oriented” first-level data inventory. The inventory data is large, the evaluation process is time-consuming and labor-intensive, and there is no directivity of carbon emissions reduction, which is not applicable to the architectural design process. Based on the life cycle assessment theory, this study aims to establish a “design-oriented” building life cycle carbon emissions calculation system and method with the goal of building carbon reduction feedback. First, based on the existing inventory analysis method, more than 2000 buildings life cycle carbon emissions databases will be established. Establishing the life cycle carbon emissions of buildings in accordance with existing building standards, norms and actual conditions for building materials processing, construction, operation, repair and renewal, demolition, waste disposal, material recycling and other aspects of building carbon emissions accounting. Standard situation." Combining the “standard scenario” with the main design elements, the statistical regression of the building life cycle carbon emissions database is carried out to establish a “design-oriented” building life cycle carbon emissions accounting system. The research results will be beneficial to the application of building life cycle carbon emissions assessment method in architectural design, and provide a theoretical basis for the scientific evaluation of energy saving and emissions reduction in China's construction industry.

在建筑设计过程中预测建筑生命周期碳排放并基于此进行碳减排设计，是降低建筑碳排放的有效手段。现有建筑碳排放计算方法都是“产品导向”的一级数据盘查，清单数据量大，评估过程费时费力，且没有碳减排的指向性，并不适用于建筑设计过程。本研究拟以生命周期评价理论为基础，以建筑减碳反馈为目标，建立“设计导向”的建筑生命周期碳排放计算体系与方法。首先基于现有的清单分析方法，建立2000个以上的建筑生命周期碳排放数据库。对于建筑碳排放核算所包含的建材生产加工、施工、运营、修缮更新、拆除、废弃物处理、材料循环再利用等方面按照现有建筑标准、规范与实际情况，建立建筑生命周期碳排放的“标准情境”。结合“标准情景”与主要设计要素，对建筑生命周期碳排放数据库进行统计回归，建立“设计导向”的建筑生命周期碳排放核算体系。研究结果将有利于建筑生命周期碳排放评价方法在建筑设计中的应用，为我国建筑行业节能减排的科学评价提供理论基础
