PROBLEM TO BE SOLVED: To solve the problems that material and component information is prepared and summed up by manual input every time, conversion information to an LCA evaluation value for each material and energy is calculated while searching it, considerable man-hours are required and erroneous input is easily generated in the LCA evaluation of a conventional OA device. SOLUTION: This LCA evaluation device is provided with a constitution tree template 3 including hierarchical constitution information corresponding to the component constitution of an OA device (PC, for instance), a material and electronic component candidate list for respective low-order components, an assembly energy candidate list and the fuel and energy candidates of distribution, use and disposal side processes after manufacture, a constitution tree preparation means 2 for presenting the template 3, urging the input of using amounts for materials for the respective components, electronic components, assembly energy and the fuel and energy of the respective processes after the manufacture and outputting the constitution information of a PC being an evaluation object and the respective using amounts, a compressed D/B 4 provided with the LCA evaluation value of material and electronic component units and the conversion value of the energy and the fuel and an LCA evaluation value calculation means for calculating evaluation values from the output and the compressed D/B 4. |
