夏热冬暖地区公共建筑全生命周期碳排放特征及减排策略研究——以厦门市为例

Study on Carbon Emission Characteristics and Emission Reduction Strategies of Public Buildings in the Hot Summer and Warm Winter Areas throughout Their Life Cycles——Take Xiamen City as an Example

公共建筑因体量大、能耗高、减排潜力大等特点,已经成为我国建筑可持续发展的重点。本文基于LCA的视角,建立公共建筑碳排放评价模型,研究夏热冬暖地区公共建筑全生命周期的碳排放特征。研究发现公共建筑在使用阶段和建材生产阶段的碳排放贡献最大,应作为减排的重点,在此基础上针对性地提出夏热冬暖地区公共建筑减排的具体措施。

Public buildings, characterized by large size,high energy consumption,great emission reduction potential and the like, have become the focus of sustainable development of buildings in China. From the perspective of LCA, this paper constructs an evaluation model for carbon emissions of public buildings to study the characteristics of carbon emissions of public buildings in the hot summer and warm winter areas throughout their life cycles. It is found from the study that public buildings make the largest contribution to carbon emissions at the stages of use, and production of building materials, which should be the focus of emission reduction, thereby proposing the concrete measures for emission reduction of public buildings in the hot summer and warm winter areas.
