Growth in the construction sector could stimulate the development of other sectors. However, the construction industry has been known as a sector that brings a great contributes to energy consumption and produces Greenhouse Gases (GHG) emissions that harm the environment. To support the implementation of sustainable infrastructure, calculating the greenhouse gas emissions produced by a construction project through its lifecycle is necessary. This study analyzes greenhouse gas emissions produced in constructing a three-story precast building. The emission source was calculated from the materials, transportation activities, and erection activities using a Life Cycle Assessment (LCA) approach. The embodied carbon data was adopted from the Inventory of Carbon and Energy (ICE) database. From the analysis that has been carried out, the precast building project generated 124.882.7 kgCO 2 eq, or 283.18 kgCO 2 eq GHG per m 2 of building. The contribution of emissions from materials, the transportation precast components, and the erection of precast components was 119.649 kgCO 2 eq (95.81%), 632.41 kgCO 2 eq (0.51%), and 4,599.30 kgCO 2 eq (3.68%) respectively.
