conomic, social, and environmental sustainability comprise the general motivations in most green building developments. Deciding to spend additional costs on the optimum benefit results generally applies the cost-benefit analysis (CBA) method to evaluate green building implementation. However, previous studies have not investigated the general aspects affecting green building achievements in CBA. This article proposes the development of a CBA method for evaluating building aspects to define the goals of green building indicators. Disaggregating of the building development attributes and indicators through literature review showed that the CBA in green building implementation measured by several aspects such as regional, knowledge-based, and economic. The research method used a simple flow diagram to classify the building development attributes and indicators. This flow process aggregates attributes and indicators based on the CBA aspects in green building implementation. In-depth interviews with several building development experts are carried out to ensure this conceptual development implemented. This work confirmed that efficiency achievement, financial evaluation, and national economic evaluation measured the feasibility of investment in green building development. Incentive schemes were expected as the financial breakthrough to enhance green building investment feasibility.
