This study aims to design a biomass utilization system considering residential energy demand. Biomass utilization system consists of 5 processes such as Resource, Preprocessing, Energy conversion, Energy consumption, and Waste treatment. In each process without Energy consumption, energy balance, CO_2 emission, and cost are evaluated. On the other hand, Energy consumption process plays a role of constraint. Especially, not only energy quantity but also energy quality is important for heat demand. In this study, biomass utilization system is modeled quantitatively and qualitatively.
