Therefore, retrofitting structure might contribute positive, impact, including cost-saving, living comfortability, environmental preservation. However, decision-making action needs detailed analysis. This identifying expenditure performance, potential benefits through lifecycle assessment cost-benefit presents Malaysia highlights twenty effective strategies successful for development. According summative analysis strategies, important element be addressed thoroughly assessing performance meet sustainability impact.
