Abstract: For heavily loaded long-span (HLS) logistics buildings, embodied CO 2 (ECO 2 ) of a structural frame accounts for more than 80% of the CO 2 emissions of the entire building. To realize a sustainable structure from the CO 2 perspective, an innovative construction method that reduces ECO 2 of a structural frame is required. Through studies conducted over several years, we have developed a SMART (Sustainable, Measurable, Attainable, Reliable, and Timely) frame that is a steel connected composite precast concrete (CPC) frame that significantly reduces not only construction time and cost but also ECO 2 . If a SMART frame is applied to HLS logistics buildings, ECO 2 reduction effects are expected to be substantial. To prove this, this study aims to analyze ECO 2 reduction effects of the CPC frame for HLS logistics buildings. An HLS logistics building constructed with the existing precast concrete (PC) frame was selected as a case project. Thereafter, the typical PC girder was redesigned using the SMART frame; then, analysis was conducted on the quantity take-off of resources, such as form, rebar, steel, and concrete, as well as on ECO 2 and production cost. As a result of the analysis, in the case of a single typical girder of the SMART frame, 730 kg-ECO 2 , which accounts for 9.52% of the CO 2 emissions, was reduced compared to that of the existing PC frame. If only the typical girders of the case project are applied, a relatively larger quantity of 465 ton-ECO 2 will be reduced. The results of this study will contribute in securing structural stability, as well as achieving a sustainable structure that leads to an unprecedented reduction of ECO 2 .
