Building construction is among the largest consumers of global energy and carbon producers. The building industry has led the public's environmental concerns such as resource depletion, climate change, and energy usage. This study presents an overview Life Cycle Assessment (LCA) of Cagayan State University - Carig Campus New Medical Building. The study follows the ISO 14040 protocol, which gives a systematic procedure of the study of building construction carbon footprint. The LCA procedure entails four general steps: goal and scope identification, inventory analysis, impact assessment, and result interpretation. The study is focused on the need for the estimation of the carbon emission of the New Medical Building. The most critical findings are that the operational stage of the building has the highest amount of carbon emission, which is a much greater amount of emission load than those generated during construction and raw material extraction. Finally, research determines that promoting environmental sustainability in institutional buildings requires a two-pronged approach: minimizing embodied carbon in building construction through better material selection and minimizing operational emissions through effective energy systems, controls, and technological upgrade.
