Abstract: When using concrete to produce exterior finishing panels of free-form building structures, different panel shapes make it difficult to reuse the forms. This results in increased formwork cost as well as a significant amount of embodied CO 2 (ECO 2 ) generation. Through years of research, we have developed a free-form panel (FCP) production technique engaging the 3D plastering technique (3DPT) without using conventional plywood forms. When 3DPT becomes available for free-form building projects, a great deal of ECO 2 reduction effects is expected in addition to reduced time and cost in FCP production. The purpose of this study is to prove this by analyzing ECO 2 reduction effects achieved through sustainable FCP production using 3DPT. The study involved project case selection, calculation of resources consumed for conventional plywood forms, and analysis of the reduction effects. As a result, it was demonstrated from the case project that 1196 tons of CO 2 were reduced using 3DPT, accounting for approximately 99% of the amount produced from conventional plywood forms (CPF). The study findings will be used as a basic reference for sustainable production of FCPs ensuring speed and precision in production as well as innovative ECO 2 reduction effects.
