“…However, even though numerous researches have highlighted the benefits of sustainable construction practice (Abidin, 2010;Sundayi et al, 2015;Whang & Kim, 2015;Afzan, 2016;Meron & Meir, 2017), construction practitioners seem to have little interest in adopting sustainable construction practice (Yahya & Abidin, 2013;Brennan & Cotgrave, 2014;Rostami et al, 2015;Afzan, 2016;Darko et al, 2017). Surveys have indicated this lack of support is due to the higher initial cost of sustainable building construction, which is termed "green cost premium" (Ahn et al, 2013;Bahaudin et al, 2013;Hwang & Ng, 2013;Brennan & Cotgrave, 2014;Shang & Peng, 2014;Qian et al, 2015;Sundayi et al, 2015;Afzan, 2016;Dodge Data & Analytics, 2016;Dwaikat & Ali, 2016;Mao et al, 2016;Amiril et al, 2017;. The following are several examples explaining the current problem regarding sustainable building construction and its higher initial cost: A study conducted on various types of sustainable buildings, such as residential, educational, office, commercial, public buildings, and health facilities, showed that the additional cost to construct such buildings is up to 12.5% (WorldGBC, 2013) and 5% to 10% (Hwang et.al, 2017) of the total construction budget.…”
