| 双碳背景下,民用建筑用能预测和节能减排方案设计研究对我国节能减排和双碳目标的实现有重要意义。建筑的围护结构是决定建筑能源性能的主要因素之一,特别是针对夏热冬暖地区建筑围护结构的能耗影响分析较少。此外,考虑到校园公共建筑在运营特性上与其他类型的公共建筑存在差异。本文以广东地区的某校园公共建筑为例,研究墙体各因素对其运行阶段能耗及建筑碳排的影响。本文建立某校园办公建筑模型,利用Energyplus软件分析不同墙体因素对建筑能耗的影响,并基于碳排因子法分析不同墙体因素对运行碳排的影响程度。开展各因素对能耗影响的敏感性分析, 研究发现:1)保温层位置对减碳效果贡献最大,其次是保温层厚度,然后是外墙结构,最后是保温层材料。2)根据以上因素的节能减碳效果得到的优化方案为选用挤塑苯乙烯泡沫板作为保温层,其厚度为 20 mm,且将该保温层设置于墙体外侧。 |

| Under the dualcarbon background, the research on predicting energy consumption and designing energy-saving and emission reduction plans for civil buildings is of great significance for achieving China"s energy-saving, emission reduction, and dual carbon goals. The enclosure structure of a building is one of the main factors determining its energy performance, especially in areas with hot summers and warm winters where there is limited analysis of the energy consumption impact of building enclosure structures. In addition, considering the differences in operational characteristics between campus public buildings and other types of public buildings. This article takes a campus public building in Guangdong Province as an example to study the impact of various wall factors on its energy consumption and building carbon emissions during operation. This article establishes a model of a campus office building, analyzes the impact of different wall factors on building energy consumption using Energyplus software, and analyzes the degree of impact of different wall factors on operational carbon emissions based on the carbon emission factor method. Conducting sensitivity analysis on the impact of various factors on energy consumption, the study found that: 1) the location of the insulation layer contributes the most to carbon reduction effect, followed by the thickness of the insulation layer, then the external wall structure, and finally the insulation layer material. 2) According to the energy saving and carbon reduction effect of the above factors, the optimization scheme is to select extruded styrene foam board as the insulation layer, with a thickness of 20 mm, and set the insulation layer outside the wall. |
