The growth of the building sector represents the progress of civilizations. There are environmental, social and economic implications, impeding the sustainability performance of buildings. A holistic life cycle sustainability assessment (LCSA) framework is inevitable to address the integrated sustainability performance of residential buildings. This paper aims to develop triple bottom line indicators to assess the sustainability performance of buildings, including sustainability objectives, impact categories and key performance indicators (KPIs) to implement in the life cycle sustainability assessment framework. The indicators have been developed through the consensus survey involving area experts from four key stakeholders' categories including, government and Engineers Australia, academia, practitioners, and structural engineers. A list of KPIs was compiled through a literature review, followed by an online census survey to collect feedback from the participants in terms of relevance and importance of initally selected KPIs. Secondly, a modified list of triple bottom line (TBL) KPIs and their weights was developed based on respondents' feedback. Finally, the threshold values were assigned to the selected KPIs and the LCSA framework was tested using a hypothetical case study. The LCSA framework using these scientifically valid KPIs would assist stakeholders to assess the sustainability performance of residential buildings and to identify the hotspots for proposing well-informed industry strategies in Western Australia.
建筑行业的发展代表着文明的进步。但它也会对环境、社会和经济产生影响，阻碍建筑的可持续性能。因此，有必要采用整体的生命周期可持续性评估（LCSA）框架来评估住宅建筑的综合可持续性能。本文旨在开发三重底线指标，以评估建筑物的可持续性能，包括可持续性目标、影响类别和关键绩效指标（KPI），以在生命周期可持续性评估框架中实施。这些指标是通过涉及包括政府和澳大利亚工程师协会在内的四个主要利益相关者类别的区域专家的共识调查制定的，其他类别还包括学术界、从业者和结构工程师。通过文献综述编制了 KPI 清单，然后通过在线普查调查收集参与者对最初选定 KPI 的相关性和重要性的反馈。其次，根据受访者的反馈，制定了经过修改的三重底线（TBL）KPI 清单及其权重。最后，为选定的 KPI 分配了阈值，并使用假设案例研究对 LCSA 框架进行了测试。使用这些经过科学验证的 KPI 的 LCSA 框架将有助于利益相关者评估西澳大利亚住宅建筑的可持续性能，并确定提出明智行业战略的热点。
