摘要

The present invention relates to a device for assessing the life-cycle sustainability of a building using a probabilistic analysis method, a method therefor, and a recording medium storing the method, wherein the life-cycle sustainability of a building is assessed and predicted probabilistically in the initial stage of a construction project. The device comprises: a first storage portion for storing a reference environmental impact assessment value regarding a reference building, a first set of environmental impact coefficients obtained by numericizing the degree of environmental impact per unit of introduction of a plurality of construction materials, and a second set of environmental impact coefficients obtained by numericizing the degree of environmental impact per unit of consumption of a plurality of energy sources; an input portion for receiving inputs of information regarding the area of a building, the amount of introduction of a plurality of construction materials, and the amount of consumption of a plurality of energy sources; a probability distribution calculation portion for storing setting values regarding probability distribution types of construction materials and of energy sources on the basis of the information regarding the area of a building, and deriving the probability distribution of the amount of introduction of the plurality of construction materials and the probability distribution of the amount of consumption of the plurality of energy sources according to the setting values with regard to the amount of introduction of the plurality of construction materials and the amount of consumption of the plurality of energy sources; a first operation portion for calculating, on the basis of Monte Carlo simulation, the probability distribution of a first environmental impact assessment value resulting from the construction materials using the probability distribution of the amount of introduction of the plurality of construction materials and the first set of environmental impact coefficients, the first operation portion calculating the probability distribution of a second environmental impact assessment value resulting from the energy sources using the probability distribution of the amount of consumption of the plurality of energy sources and the second set of environmental impact coefficients, and the first operation portion adding the probability distribution of the first environmental impact assessment value and the probability distribution of the second environmental assessment value, thereby calculating the probability distribution of a life-cycle environmental impact assessment value; and a first output portion for deriving the probability distribution of the probability distribution of an environmental impact index by dividing the reference environmental impact assessment value stored in the first storage portion by the probability distribution of the life-cycle environmental impact assessment value calculated by the first operation portion, and outputting the derived probability distribution of the environmental impact index.
