本文报道了对改造和新建两种典型住宅的环境性能进行研究的结果。翻新工程按照Passivhaus标准完成，而新建筑则按照爱尔兰现行建筑法规完成。使用生命周期评估来衡量翻新和新建筑的环境绩效，检查了50年和80年生命周期中的组装、运行和报废阶段。利用基本信息、生命周期评估软件和生命周期评估数据库，模拟了每个阶段的环境影响。这两个案例研究的运作阶段被发现是造成最严重环境破坏的根源，其次分别是组装阶段和报废阶段。装配和寿命终结阶段的相对重要性随着寿命的延长而降低。研究发现，改造后的房屋在装配和使用阶段的性能优于新建筑，而新建筑的性能则优于新建筑。
This paper reports the findings of research on the environmental performance of two case-study houses, a retrofit and new build. The retrofit was completed to a Passivhaus standard while the new build was completed to current Irish building regulations. Environmental performance of the retrofit and new build was measured using life-cycle assessments, examining the assembly, operational and end-of-life stage over life spans of 50 and 80 years. Using primary information, life-cycle assessment software and life-cycle assessment databases the environmental impacts of each stage were modelled. The operational stage of both case studies was found to be the source of the most significant environmental damage, followed by the assembly and the end-of-life stage respectively. The relative importance of the assembly and end-of-life stage decreased as the life span increased. It was found that the retrofit house studied outperformed the new build in the assembly and operational stage, whereas the new build performed ...
