With the gradual warming of the global climate, the development of low-carbon buildings has become an inevitable trend, and research on the carbon emissions of buildings is also imperative. At present, in most studies on energy management of carbon emissions during the construction process, people cannot analyze them with a more accurate method. In order to find an effective carbon emission analysis method, based on the life cycle assessment method (LCA), this paper establishes a carbon emission model, and calculates the carbon emission of residential building materials in different areas, building materials in different industrial buildings, air conditioning cooling and heating schemes, and the whole life cycle of buildings. This article draws the following conclusions: The relationship between the carbon emissions of residential building materials in different regions is: severe cold area > cold area > hot summer and cold winter area > mild area > hot summer and warm winter area. In the analysis of frame structure, brick concrete structure and steel concrete structure, the most carbon emission is steel concrete structure, and the least is frame structure. The carbon emissions of different forms of air-conditioning cold sources are different. Among them, the second option is the direct-fired lithium bromide absorption chiller and hot water unit. The carbon emissions are related to the energy structure. For prefabricated buildings, the proportion of carbon emissions in the construction use phase is the highest, reaching 75% to 80%, and the sum of the construction use phase and the building material production phase accounts for more than 90% of the total.

基于LCA的预制建筑的碳排放能量管理分析

随着全球气候的逐渐升温,低碳建筑的发展已成为必然趋势,对建筑碳排放的研究也势在必行。目前,在大多数建筑过程中碳排放能量管理的研究中,人们无法用更准确的方法对其进行分析。为了找到有效的碳排放分析方法,本文基于生命周期评估方法(LCA)建立了碳排放模型,并计算了不同区域的住宅建筑材料,不同工业建筑的建筑材料的碳排放量,空调制冷和供暖方案,以及建筑物的整个生命周期。本文得出以下结论:不同地区民用建筑材料碳排放之间的关系为:严寒地区>严寒地区>炎热夏季和严寒地区>温和地区>炎热夏季和严寒地区 在框架结构,砖混结构和钢混结构的分析中,碳排放量最多的是钢混结构,最少的是框架结构。不同形式的空调冷源的碳排放量也不同。其中,第二种选择是直燃式溴化锂吸收式制冷机和热水装置。碳排放与能源结构有关。对于预制建筑物,在建筑使用阶段的碳排放比例最高,达到75%至80%,
