Abstract
Abstract
Construction activities gradually consume energy during their life cycle, namely material extrusion, transportation, production, assembly line, installation, demolition and disposal. This research aimed to identify research about energy such as embodied and operational energy. Operational energy is energy that is used during building life cycle to decrease global warming effect. This research used a qualitative method to identify and review some literature related to decreased energy construction. This study showed that 98% of researchers focus on energy efficiency in the design, construction and operational stages. Only 2% were investigating at the initiation stage. Some recommendations can be drawn suggesting that energy reduction is possible by applying optimization strategy to all project life cycle (PLC). Initiation and design phase are indirect energy optimization phase through policies and design buildings, which significantly impact energy decrease for further phases. In contrast, construction and operations phase is direct energy optimization phase through energy efficiency on each activity.
