【摘要】：近年来,全球气候变暖等这些环境问题已成为了国际社会所关注焦点,其中主要成是二氧化碳。在建筑行业,在公共建筑的同步增长,所以公共建筑是建筑在建筑节能的重中之重。随着中国建筑业风生水起,正在产生大量的二氧化碳排放量来自建筑物,从而减少排放是非常重要的。本文通过生命周期理论(LCA)对公共建筑进行了碳排放源边界界定,再通过时间节点划分为生产和建材,建筑,维护,建筑垃圾回收利用这四个阶段,再根据物质流、能量流细分为统五个子系统。通过对国内外文献查阅、对相关数据进行计算与分析,可以得到关于主要建材、化石能源以及电力等物质的碳排放因子。通过子系统碳排放的各个阶段物质流-能量流计算分析,包含设备的主要类型和使用量,运输设备类型和能源消耗,建筑机械和设备类型号机械台班建材和施工,运营使用阶段,建立了公共建筑碳排放计算模型。然后,以北京市某写字楼这个公共建筑,通过研究和分析的项目,以研究各子系统办公室的碳排放和碳排放在生命周期的各个阶段的比例。最后,针对公共建筑生命周期以及物质流-能量流衍生出来四个阶段以及五个系统基于生命周期理论和碳交易两个视角提出相应碳减排的对策。本文所研究碳排放的计算模型可以用于公共建筑碳排量的计算,对碳减排提出了政策研究的方法,以扩大节能建筑工程,建设低碳发展,科学发展的政策也提供了相应的理论依据。
[Abstract]:In recent years, global warming and other environmental issues have become the focus of international attention, mainly carbon dioxide. In the construction industry, the growth of public buildings, so public buildings are the most important building energy-saving. It is important to reduce carbon dioxide emissions from buildings as wind-induced water in China's construction industry rises. In this paper, the boundary of carbon emission source of public buildings is defined by life cycle theory (LCA), and the time nodes are divided into four stages: production and building materials, building, maintenance, construction waste recycling, and then according to the material flow. The energy flow is subdivided into five subsystems. The carbon emission factors of the main building materials, fossil energy and electric power can be obtained by consulting the domestic and foreign literature and analyzing the relevant data. Through the calculation and analysis of material flow-energy flow in each stage of carbon emission of subsystems, including the main types and usage of equipment, the type of transportation equipment and energy consumption, the building materials and construction of construction machinery and equipment types. In the stage of operation, the calculation model of carbon emission of public buildings is established. Then, with a public building in Beijing, through research and analysis of the project, to study the subsystems of the office carbon emissions and carbon emissions at all stages of the life cycle. Finally, based on the theory of life cycle and carbon trading, the corresponding countermeasures of carbon emission reduction are put forward for the four stages of life cycle and the derivation of material flow-energy flow from the public building life cycle and the five systems based on the theory of life cycle and carbon trading. The carbon emission calculation model studied in this paper can be used to calculate the carbon emission of public buildings. The policy research method of carbon emission reduction is put forward in order to expand the energy saving building project and build low carbon development. The policy of scientific development also provides the corresponding theoretical basis.
