Device and method for building life cycle sustainability assessment using probabilistic analysis method, and recording medium storing the method

A device and method for building life cycle sustainability assessment using probabilistic analysis method, the device and method being capable of assessing and predicting building life cycle sustainability, and a recording medium storing the method. The device includes: a first storage unit storing a reference environmental impact assessment value of a reference building, and first and second environmental impact coefficient groups; an input unit receiving area information, amounts of building materials and energy sources; a probability distribution calculating unit storing a set value, and deducing probability distributions of the building materials and the energy sources; a first arithmetic unit calculating probability distributions of first and second environmental impact assessment values, and a probability distribution of a life cycle environmental impact assessment value; and a first output unit deducing a probability distribution of an environmental impact index, and outputting the deduced probability distribution of the environmental impact index.
