Repetitive reuse of components is expected to contribute to the reduction of energy use in construction process of detached houses. However, quantitative methodology to evaluate the potential reduction has not been established. The paper presents the methodology to evaluate the potential reduction by developing the energy use model of two generations of production process where components used in the house of first generation is reused in the house of second generation. Then the paper shows case studies to estimate the embodied energy over two generations in terms of four detached houses with same schematic planning by completely different building methods. The result of case studies demonstrates that intensive degree of reuse of components could generate up to 20% reduction of embodied energy for two generations' houses.
