“…According to several studies, it is stated that energy optimization should be carried out in the pre-construction and construction phases which will directly affect a significant reduction in the operation phase [2,24]. The Embodied energy control in building materials used for building construction can have an impact efficiency of up to 60% of the energy life cycle.…”

The construction industries had a significant role as emission gas contributors through direct activities, such as the construction process, the operation and demolition of the building, and indirect activities, which is the designing process to decide the types of materials and the shapes of the building. This paper aimed to create an embodied and operational energy assessment concept based on a project life cycle using qualitative methods through a research questionnaire. In the questionnaire, there were 18 indicators based on a literature review relating to embodied and operational energy within the scope of the project life cycle (initiation, design, construction, and operation). Indicator assessment used a Likert scale and was analyzed by Structural Equation Modeling Partial Least Squares. Respondents in this study include consultants, contractors, and stakeholders. The results of the study showed a significant relationship between the initiation and design phases of the construction phase and the operational phase to minimize energy. Stakeholder commitment to the environment and planning that prioritizes energy efficiency (embodied and operational energy) had the highest T-Statistic values of 100.479 and 61.581 with a 95% confidence level. This showed the role of stakeholders and designers is crucial to the reduction in energy embodied and operational during the project life cycle, so that awareness and commitment are needed in realizing green construction.

“…Management's role is indispensable for monitoring and maintenance because bridge management consists of various activities ranging from planning to replacement. Maintenance is the final stage of a project, which passes due diligence to ensure its safety for users [1]. In addition to providing security, such as building maintenance, bridge maintenance also aims to minimize repair costs [2].…”
