Abstract Different construction activities may indicate distinct environmental impacts due to their uniqueness. Ability to assess and compare the environmental impacts from different construction activities can aid the process of minimising emissions at different building construction processes. The study presents a comparative impact assessment methodology to evaluate environmental impacts at different activities during the building construction stage. Significant impact related construction activities for five major impact categories namely global warming potential (GWP 100), acidification potential (AP), Eutrophication potential (EP), Photochemical oxidation formation potential (POFP) and Human toxicity potential (HTP) are compared from the global, regional and local perspectives. A case study of a residential building in Australia is used to demonstrate the application of the functions of the developed method. The results of the case study indicated that the method can be effectively used to compare environmental impacts of different construction activities at different geographical perspectives considered. The method can be used by designers and contractors in comparing impacts of various construction activities to identify the most emission effective construction processes.

一种建筑施工活动废气排放影响评价的比较方法

摘要 不同的建设活动由于其独特性，可能表现出不同的环境影响。评估和比较不同建筑活动对环境的影响的能力有助于最大限度地减少不同建筑施工过程中的排放。该研究提出了一种比较影响评估方法，以评估建筑施工阶段不同活动的环境影响。与全球变暖潜能值 (GWP 100)、酸化潜能值 (AP)、富营养化潜能值 (EP)、光化学氧化形成潜能值 (POFP) 和人类毒性潜能值 (HTP) 五个主要影响类别的重大影响相关的建设活动与全球进行了比较。 、区域和地方观点。澳大利亚住宅建筑的案例研究用于演示所开发方法的功能的应用。案例研究的结果表明，该方法可以有效地用于比较不同地理视角下不同施工活动的环境影响。设计师和承包商可以使用该方法比较各种施工活动的影响，以确定最有效的施工过程。
