Potential Leading Sustainability Performance Indicators for Sustainable Low-Income Housing

Sustainability performance indicators (SPIs) are flexible tools developed based on specific frameworks to provide integrative strategies to assess sustainability. Indicators represent the pressing concerns and reflect the interests of project stakeholders. The residents' satisfaction level and the perspective of experts provide a solid base for identifying SPIs. Several frameworks and sets of indicators have been used. The triple bottom line +1 (TBL+1), which indicates social, environmental, economic, and governance aspects, was used here as an integrative framework to assess sustainability. This paper identifies and summarizes the significant potential leading sustainability performance indicators (PLSPIs) for low-income housing (LIH). A systemic literature review adapting three research design stages was used to identify and summarize the significant PLSPIs. Due to the length limitation, the paper presents two sets of PLSPIs, the PLSPIs related to social and environmental aspects. These sets include 10 social PLSPIs (SPLSPIs) and 14 environmental PLSPIs (EPLSPIs).
