Abstract
While numbers of green projects have been increasing recently, supported with various sustainable efforts implemented globally, still the sustainable impacts is considered as insignificant. Previous research reveals that this happen due to numbers of newly built sustainable building is small compared to existing building stock. Hence, to achieve better sustainability objectives, greening existing building through refurbishment has been introduced. This paper attempts to explore sustainable indicators that are required to assess the performance of existing building. To ensure the indicators incorporate triple pillars of sustainability, the concept of Life Cycle Sustainability Assessment (LCSA) will be adopted. Comparative methodology was used where six (6) prominent green building rating tools were reviewed and compared with literature to gather preliminary list of indicators and sub-indicators. Among selected tools include BREEAM, LEED, Green Mark, GBI, GreenRE, and MyCREST. Experts validation were conducted to further validate the list of indicators gathered. Upon completion, a total of 87 assessment indicators were proposed to greening existing buildings. These sub-indicators were grouped according to the components of LCSA namely environmental (40 indicators), social (43 indicators), and economic (4 indicators). © 2020, Construction Research Institute of Malaysia.
