建筑物占全球能源使用量的40％以上，以及发达国家和发展中国家的全球温室气体排放量的33％。但是，尚未进行基于ecotect和Nanjing发展中的建筑物信息建模的建筑物生命周期的碳排放研究。因此，本文的结果和建议代表了对有关该主题的文献的贡献。本文的科学价值是，在建筑物的生命周期中，Ecotect和建筑信息建模可能有助于简化碳排放量的估计，因为它们可以提供大多数信息和计算工具，这可能会缓解执行建筑物LCA时不足的信息问题。通过更改几个参数来确定对建筑物绩效影响最大的参数来进行灵敏度分析。每个阶段的生命周期碳排放量的比较表明，操作阶段是碳排放的最大贡献者。在运行过程中，大约有85.4％的碳排放量产生。施工阶段占碳排放总量的12.6％。总碳排放量的大约2％发生在拆除阶段。与建筑物的整个生命周期中的总碳排放相比，植被固结是最小的。因此，这些发现表明，政府可以通过针对建筑物的运营阶段来实现碳排放量最大的减少。但是，解决非运营阶段的机会不应被忽视，因为非运营阶段每年工作区域的平均碳排放量远大于使用阶段的平均碳排放。 （c）2015 Elsevier Ltd.保留所有权利。
Buildings are responsible for more than 40% of global energy usage and as much as 33% of global greenhouse gas emissions in both developed and developing countries. However, the study of carbon emissions over a building's life cycle based on Ecotect and building information modeling in developing areas of Nanjing has yet to be conducted. Therefore, the results and recommendations of this paper represent a contribution to the literature on this topic. The scientific value of this paper is that Ecotect and building information modeling can be helpful in simplifying the estimation of carbon emissions over a building's life cycle because they can provide a majority of the information and calculation tools necessary for performing an life cycle assessment (LCA), which may alleviate the problem of insufficient information when executing an LCA of a building. A sensitivity analysis was performed by changing several parameters to identify the parameters that have the largest impacts on the performance a building. A comparison of the life cycle carbon emissions for each stage showed that the operational stage is the largest contributor to carbon emissions. Approximately 85.4% of the total carbon emissions were generated during operation. The construction stage accounted for 12.6% of the total carbon emissions. Approximately 2% of the total carbon emissions occurred during the demolition stage. Compared to the total carbon emissions over the entire life cycle of the building, carbon sequestration by vegetation was minimal. Thus, these findings indicate that governments can achieve the greatest reductions in carbon emissions by targeting the operational phase of buildings. However, the opportunity for addressing non-operational phases should not be ignored because the average carbon emissions per working area per year of non-operational stages are far greater than those of the use phase.
